Millions of marine fishes and invertebrates are removed from coral reefs and associated habitats each year. The majority are imported into the United States, with the remainder sent to Europe, Japan, and a handful of other countries. Despite the recent growth and diversification of the aquarium trade, to date, data collection is not mandatory, and hence comprehensive information on species volume and diversity is lacking. This lack of information makes it impossible to study trade pathways. Without species-specific volume and diversity data, it is unclear how importing and exporting governments can oversee this industry effectively or how sustainability should be encouraged. To expand our knowledge and understanding of the trade, and to effectively communicate this new understanding, we introduce the publically-available Marine Aquarium Biodiversity and Trade Flow online database (https://www.aquariumtradedata.org/). This tool was created to communicate the volume and diversity of marine fishes and/or invertebrates imported into the US over three complete years (2008, 2009, and 2011) and three partial years (2000, 2004, 2005). To create this tool, invoices pertaining to shipments of live marine fishes and invertebrates were scanned and analyzed for species name, species quantities, country of origin, port of entry, and city of import destination. Here we focus on the analysis of the later three years of data and also produce an estimate for the entirety of 2000, 2004, and 2005. The three-year aggregate totals (2008, 2009, 2011) indicate that just under 2,300 fish and 725 invertebrate species were imported into the US cumulatively, although just under 1,800 fish and 550 invertebrate species were traded annually. Overall, the total number of live marine animals decreased between 2008 and 2011. In 2008, 2009, and 2011, the total number of individual fish (8.2, 7.3, and 6.9 million individuals) and invertebrates (4.2, 3.7, and 3.6 million individuals) assessed by analyzing the invoice data are roughly 60% of the total volumes recorded through the Law Enforcement Management Information System (LEMIS) dataset. Using these complete years, we back-calculated the number of individuals of both fishes and invertebrates imported in 2000, 2004, and 2005. These estimates (9.3, 10.8, and 11.2 million individual fish per year) were consistent with the three years of complete data. We also use these data to understand the global trade in two species (Banggai cardinalfish, Pterapogon kauderni, and orange clownfish, Amphiprion ocellaris / percula) recently considered for Endangered Species Act listing.

INTRODUCTIONThe live aquarium fish trade faces a multitude of potential threats including incidences ofreduced biodiversity from over-extraction habitat destruction in some source countries(Francis-Floyd amp Klinger 2003 Gopakumar amp Ignatius 2006) and negative impacts ofspecies invasions in the US and elsewhere (Chucholl 2013 Garciacutea-Berthou 2007Holmberget al 2015 Padilla amp Williams 2004) Despite these threats the aquarium trade can be aunique and significant positive force in reef-side communities (Rhyne Tlusty amp Kaufman2014) Benefits include but are not limited to saving threatened species from the brinkof extinction through the development of captive breeding programs (Tlusty 2002) andcatalyzing habitat preservation through sustainable supply-side practices (Firchau Dowd ampTlusty 2013) These sustainable practices include stewardship mechanisms for sustainablelivelihoods via poverty alleviation and the protection of threatened ecosystems (RhyneTlusty amp Kaufman 2014) Finally consumer education of aquarium trade sustainabilitycan promote widespread public appreciation for the worldrsquos aquatic ecosystems with theultimate goal of minimizing negative impacts of this trade (Tlusty et al 2013) While aproactive stance can transform a large consumer base into a powerful agent for biodiversityconservation increased sustainability and human well-being inaction will likely amplifythe deleterious threats currently faced by the trade Currently the lack of oversight leadingto a poor concept of trade volume and subsequent regulatory inefficiency has greatlyhampered the development of a sustainable industry Increasing the sustainability of themarine aquarium animal industry should be considered a primary initiative for the entireaquarium industry transport chain (Tlusty et al 2013) Increasing the sustainability ofthe transport chain of marine aquarium animals is achieved through a more thoroughunderstanding of the magnitude of the trade (Fujita et al 2014) which begins by assessingthe scale of imports into the US (the primary destination) (Rhyne et al 2012) Once theannual volume of US imports is gauged other relevant issues that lead to environmentaland economic benefits can then be tackled including animal quality and shipping survival

There is no clear picture of the number of live marine fish and invertebrate species orindividuals involved in the aquarium trade primarily due to insufficient global trackingof the import and export of these animals (Bruckner 2001 Fujita et al 2014 Green 2003Lunn amp Moreau 2004 Tissot et al 2010 Wabnitz et al 2003) Multiple sources of datahave been used to monitor this trade (Green 2003 Smith et al 2008 Wabnitz et al 2003Wood 2001) However not all of these data systems are sufficient for or were even intendedfor monitoring the aquarium trade For example compulsory data are maintained underfederal mandates for species listed by the Convention on International Trade in Endangered

Rhyne et al (2017) PeerJ DOI 107717peerj2949 236

Species of Wild Fauna and Flora (CITES) However previous studies found that CITESrecords were inaccurate incomplete or insufficient (Bickford et al 2011 Blundell ampMascia 2005 Rhyne et al 2012) Furthermore CITES-listed species (namely stony coralsgiant clams and seahorses) account for only a fraction of the total trade in live aquaticanimals Only a handful of studies (Rhyne et al 2012 Smith et al 2009 Smith et al 2008)have attempted to quantify the movement of non-CITES-listed aquarium species fromsource to market The Global Marine AquariumDatabase (GMAD) encouraged companiesto provide data on the marine aquarium trade (Green 2003) and until now GMAD wasthe only source for aquarium trade data recorded at a species-specific level While GMADcontains trade data from 1988 to 2003 some years and countries (eg Haiti) are missingand values reported in GMAD were found to be drastically fewer than other estimates oftrade data (Murray et al 2012) Furthermore the aquarium trade has been transformedby new technologies and husbandry breakthroughs since 2003 (Rhyne amp Tlusty 2012)which may dilute the relevance of this data set In addition to CITES and GMAD the LawEnforcement Management Information System (LEMIS) database has been used to betterunderstand the aquarium trade The United States Fish and Wildlife Service (USFWS)inspects wildlife shipments and through LEMIS maintains species-specific data in the caseof transporting CITES-listed species per CITES requirements However non-CITES-listedspecies are recorded with general codes (eg marine aquarium tropical fish regardless ofspecies are coded MATF) Recording data in this generalized manner eliminates specificinformation regarding the diversity and volumes of species traded (Smith et al 2009)While the need for accurate accounts of aquarium trade flow continually increases thecurrent monitoring methods remain static (Bickford et al 2011) The lack of specific datasystems for recording all species exported and imported for the marine aquarium traderaises two main concerns (1) because of the lack of trade data it is unclear how importingand exporting governments can monitor this industry effectively (2) it is also unclear howsustainability should be encouraged given the paucity of data

To date Balboa (2003) Wabnitz et al (2003) and Rhyne et al (2012) have cataloguedspecies-specific information provided on trade invoices Rhyne et al (2012) furthercompared invoice information to associated shipment declarations It was this effortthat led to the development of the Marine Aquarium Biodiversity and Trade Flow onlinedatabase (httpswwwaquariumtradedataorg) a public portal offering anonymized livemarine animal trade data collected through trade invoices Here we describe three years(2008 2009 2011) of fish and invertebrate invoice-based data from US imports that wereanalyzed for country of origin port of entry and quantity of species and individualsassociated with each port We also relate the findings from these three years of completetrade data to previously existing invoice-based trade data from the LEMIS databaseSpecifically Rhyne et al (2012) described one contiguous year of import data based on a12-month period from June 2004 (sevenmonths) untilMay 2005 (fivemonths) and Balboa(2003) described one month (October) of data from 2000 To address the missing monthsof data from these years and to increase the scope of the dataset we modeled data for themissing months based on the monthly volume patterns analyzed from the three completeyears of data available (2008 2009 2011) This work provides an enlarged snapshot of the

volume biodiversity and trade pathways for live marine aquarium fish and invertebratespecies beyond the information provided by other reporting systems (Wabnitz et al2003) Further this work demonstrates that LEMIS while well-designed for importexportcompliance and management of USFWS staffing needs is not designed to monitor thespecies-level activity of the live marine aquarium trade Finally we present two casestudies (the Banggai cardinalfish Pterapogon kauderni and the commonorange clownfishAmphiprion ocellarispercula) to demonstrate the use of these data for better understandingthe trade in marine species a first step toward advancing industry sustainability

METHODSThe goal of this project was to evaluate the number of live marine aquarium speciesimported into the US and to create a trade path analysis of the diversity of animalsinvolved in the trade The methods used to analyze trade invoices were described byRhyne et al (2012) and are briefly summarized here We reviewed all USFWS shipmentdeclarations and the attached commercial invoices coded as Marine Aquarium TropicalFish (MATF) for 2008 2009 and 2011 as indicated in the LEMIS database Whileabout 22000 invoices were marked as containing MATF in the LEMIS database wereceived approximately 20000 shipment declarations and their attached invoices CITESdata are specially coded on import declarations and thus are not integrated into thisdatabase

Invoices were considered a true statement of shipping contents as we were not able toassess the veracity of the information contained on the invoice Shipment information (dateport of origin and destination port) was collected from the declaration page and speciesand quantity information was tabulated from the associated invoices and catalogued into adatabase Within the trade of live marine organisms re-export information is not recordedand thus could not be assessed here Both manual entry and automated optical characterrecognition (OCR) software (ABBYY FlexiCapture 90) customized for wildlife shipments(Fig 1) were utilized to retrieve the above information from these documents The inputmethod varied with invoice quality and length Manual entry was utilized when invoiceswere of poor quality (blurry speckled darkened fonts less than six point handwritten) orbrief (less than 12 page) whereas all others were read using the OCR software Once allnecessary data were captured species names were verified using World Register of MarineSpecies (WoRMS Editorial Board 2015) FishBase (Froese amp Pauly 2015) and the primaryliterature (Appeltans et al 2011 Froese amp Pauly 2011) We corrected species informationonly when species names were misspelled listed under a junior synonym or listed byonly a common name Species were identified to the greatest taxonomic detail availableOccasionally genera were listed without species (eg lsquoChrysiptera sprsquo) or the specieswas otherwise ambiguous (eg lsquohybrid Acanthurus tangrsquo) In these cases the genus (andall higher-level taxonomic information) would be recorded and the species would berecorded as unknown Genus and species were recorded as unknown when listed onlyby an ambiguous common name (eg lsquocolorful damselrsquo lsquounknown damselrsquo lsquoassorteddamselsrsquo)

To determine if the volume of captive-bred P kauderni imported into the US hasincreased in recent years we reviewed invoice data from Los Angeles-based importerQuality Marine for two additional recent years of imports Quality Marine sourced fishfrom Thailand and these were known to have been captive-bred given that Thailandlies outside the native range of P kauderni At our request all shipments of MATF fromThailand to Quality Marine over the period of March 2012 to July 2014 were supplied andreviewed

In accordance with Rhyne et al (2012) this report focused on major geographic tradeflows the frequency of invoice detail to species-level and how invoice data compared toLEMIS data Invoice data for both fishes and invertebrates were retrieved concurrentlyTo help organize and visualize the trade data a publically accessible representation of thetrade data was created the Marine Aquarium Biodiversity and Trade Flow online database(httpswwwaquariumtradedataorg) This web-based graphical user interface poweredby the open source JavaScript library D3 (httpd3jsorg) is data-rich visually appealingand allows users to query more than 28000 invoices containing over 27 million lines ofinvoice data from 2000 2004 2005 2008 2009 and 2011

To back-calculate the estimated total annual imports of marine animals during yearswith incomplete data sets (years 2000 2004 2005) we first determined the proportion ofindividuals imported during the time interval (one month for 2000 sevenmonths for 2004and five months for 2005) based on the three years for which we had a complete 12-monthdataset (2008 2009 and 2011) For these three years there was variation between monthsbut the intra-month variation was less than that of the inter-month variation suggesting

Rhyne et al (2017) PeerJ DOI 107717peerj2949 536

that monthly import volumes were proportionally consistent This proportion was thenused to calculate the number of individuals for the unknown months using the followingrelation

(nPr)minusn

where n is the known number of imports per year for 1 (2000) 5 (2004) or 7 (2005)months and Pr is the average proportion of known imports from corresponding monthsfrom 2008 2009 and 2011 This estimated number of animals was then allocated across theunknown months proportionally for 2000 2004 and 2005 This method appears robustgiven the consistency of the most voluminous species across years (see results) We alsogenerated estimates for the source countries and ports of entry The database user canselect the type of data to view and within the selection tool can select to view actual dataor whether estimates should be included Even though these numbers are estimates wepresent them as numbers so that they coalesce with the complete database

increased to 1798 by 2011 While no more than 1800 species were imported in a singleyear 2278 unique species were imported across the three-year span (Table 1)

A similar trend in the overall trade was observed for non-CITES-listed invertebratesduring this time period although the invertebrate data were less voluminous and speciouscompared to the fish data A total of 43 million invertebrates representing 545 species wereimported into the US in 2008 The total number of invertebrates imported decreased toabout 37 million in 2009 and 2011 (Table 2) A total of 724 species were imported overthe three-year span Compared to fishes relatively fewer invertebrates were identified tospecies-level (729)

Export countriesForty-five countries in total exported marine fishes to the US during the three years(Table 1) with 41 37 and 36 countries noted in 2008 2009 and 2011 respectively ThePhilippines exported 56 of the cumulative total volume (127 million fishes Fig 5)The overall volume of fishes traded decreased by 17 between 2008 and 2011 withcommensurate export decreases from the Philippines and Indonesia Third-ranked SriLanka exported consistently across the three years Exports from fourth-ranked Haitidecreased by nearly 50 between 2008 and 2011 likely due to earthquake activity in 2010

The US imported marine invertebrates from a total of 38 countries during the threeyears (Fig 5 Table 2) although only 27 (2008 2009) or 28 (2011) countries were noted peryear The number of individuals exported per year decreased 14 between 2008 and 2011a rate similar to that of fishes The countries exporting the greatest volume over the threeyears were the Philippines (36 million invertebrates) and Haiti (31 million invertebrates)The number of individual invertebrates exported from the Philippines increased by 24

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

INTRODUCTIONThe live aquarium fish trade faces a multitude of potential threats including incidences ofreduced biodiversity from over-extraction habitat destruction in some source countries(Francis-Floyd amp Klinger 2003 Gopakumar amp Ignatius 2006) and negative impacts ofspecies invasions in the US and elsewhere (Chucholl 2013 Garciacutea-Berthou 2007Holmberget al 2015 Padilla amp Williams 2004) Despite these threats the aquarium trade can be aunique and significant positive force in reef-side communities (Rhyne Tlusty amp Kaufman2014) Benefits include but are not limited to saving threatened species from the brinkof extinction through the development of captive breeding programs (Tlusty 2002) andcatalyzing habitat preservation through sustainable supply-side practices (Firchau Dowd ampTlusty 2013) These sustainable practices include stewardship mechanisms for sustainablelivelihoods via poverty alleviation and the protection of threatened ecosystems (RhyneTlusty amp Kaufman 2014) Finally consumer education of aquarium trade sustainabilitycan promote widespread public appreciation for the worldrsquos aquatic ecosystems with theultimate goal of minimizing negative impacts of this trade (Tlusty et al 2013) While aproactive stance can transform a large consumer base into a powerful agent for biodiversityconservation increased sustainability and human well-being inaction will likely amplifythe deleterious threats currently faced by the trade Currently the lack of oversight leadingto a poor concept of trade volume and subsequent regulatory inefficiency has greatlyhampered the development of a sustainable industry Increasing the sustainability of themarine aquarium animal industry should be considered a primary initiative for the entireaquarium industry transport chain (Tlusty et al 2013) Increasing the sustainability ofthe transport chain of marine aquarium animals is achieved through a more thoroughunderstanding of the magnitude of the trade (Fujita et al 2014) which begins by assessingthe scale of imports into the US (the primary destination) (Rhyne et al 2012) Once theannual volume of US imports is gauged other relevant issues that lead to environmentaland economic benefits can then be tackled including animal quality and shipping survival

There is no clear picture of the number of live marine fish and invertebrate species orindividuals involved in the aquarium trade primarily due to insufficient global trackingof the import and export of these animals (Bruckner 2001 Fujita et al 2014 Green 2003Lunn amp Moreau 2004 Tissot et al 2010 Wabnitz et al 2003) Multiple sources of datahave been used to monitor this trade (Green 2003 Smith et al 2008 Wabnitz et al 2003Wood 2001) However not all of these data systems are sufficient for or were even intendedfor monitoring the aquarium trade For example compulsory data are maintained underfederal mandates for species listed by the Convention on International Trade in Endangered

Rhyne et al (2017) PeerJ DOI 107717peerj2949 236

Species of Wild Fauna and Flora (CITES) However previous studies found that CITESrecords were inaccurate incomplete or insufficient (Bickford et al 2011 Blundell ampMascia 2005 Rhyne et al 2012) Furthermore CITES-listed species (namely stony coralsgiant clams and seahorses) account for only a fraction of the total trade in live aquaticanimals Only a handful of studies (Rhyne et al 2012 Smith et al 2009 Smith et al 2008)have attempted to quantify the movement of non-CITES-listed aquarium species fromsource to market The Global Marine AquariumDatabase (GMAD) encouraged companiesto provide data on the marine aquarium trade (Green 2003) and until now GMAD wasthe only source for aquarium trade data recorded at a species-specific level While GMADcontains trade data from 1988 to 2003 some years and countries (eg Haiti) are missingand values reported in GMAD were found to be drastically fewer than other estimates oftrade data (Murray et al 2012) Furthermore the aquarium trade has been transformedby new technologies and husbandry breakthroughs since 2003 (Rhyne amp Tlusty 2012)which may dilute the relevance of this data set In addition to CITES and GMAD the LawEnforcement Management Information System (LEMIS) database has been used to betterunderstand the aquarium trade The United States Fish and Wildlife Service (USFWS)inspects wildlife shipments and through LEMIS maintains species-specific data in the caseof transporting CITES-listed species per CITES requirements However non-CITES-listedspecies are recorded with general codes (eg marine aquarium tropical fish regardless ofspecies are coded MATF) Recording data in this generalized manner eliminates specificinformation regarding the diversity and volumes of species traded (Smith et al 2009)While the need for accurate accounts of aquarium trade flow continually increases thecurrent monitoring methods remain static (Bickford et al 2011) The lack of specific datasystems for recording all species exported and imported for the marine aquarium traderaises two main concerns (1) because of the lack of trade data it is unclear how importingand exporting governments can monitor this industry effectively (2) it is also unclear howsustainability should be encouraged given the paucity of data

To date Balboa (2003) Wabnitz et al (2003) and Rhyne et al (2012) have cataloguedspecies-specific information provided on trade invoices Rhyne et al (2012) furthercompared invoice information to associated shipment declarations It was this effortthat led to the development of the Marine Aquarium Biodiversity and Trade Flow onlinedatabase (httpswwwaquariumtradedataorg) a public portal offering anonymized livemarine animal trade data collected through trade invoices Here we describe three years(2008 2009 2011) of fish and invertebrate invoice-based data from US imports that wereanalyzed for country of origin port of entry and quantity of species and individualsassociated with each port We also relate the findings from these three years of completetrade data to previously existing invoice-based trade data from the LEMIS databaseSpecifically Rhyne et al (2012) described one contiguous year of import data based on a12-month period from June 2004 (sevenmonths) untilMay 2005 (fivemonths) and Balboa(2003) described one month (October) of data from 2000 To address the missing monthsof data from these years and to increase the scope of the dataset we modeled data for themissing months based on the monthly volume patterns analyzed from the three completeyears of data available (2008 2009 2011) This work provides an enlarged snapshot of the

volume biodiversity and trade pathways for live marine aquarium fish and invertebratespecies beyond the information provided by other reporting systems (Wabnitz et al2003) Further this work demonstrates that LEMIS while well-designed for importexportcompliance and management of USFWS staffing needs is not designed to monitor thespecies-level activity of the live marine aquarium trade Finally we present two casestudies (the Banggai cardinalfish Pterapogon kauderni and the commonorange clownfishAmphiprion ocellarispercula) to demonstrate the use of these data for better understandingthe trade in marine species a first step toward advancing industry sustainability

METHODSThe goal of this project was to evaluate the number of live marine aquarium speciesimported into the US and to create a trade path analysis of the diversity of animalsinvolved in the trade The methods used to analyze trade invoices were described byRhyne et al (2012) and are briefly summarized here We reviewed all USFWS shipmentdeclarations and the attached commercial invoices coded as Marine Aquarium TropicalFish (MATF) for 2008 2009 and 2011 as indicated in the LEMIS database Whileabout 22000 invoices were marked as containing MATF in the LEMIS database wereceived approximately 20000 shipment declarations and their attached invoices CITESdata are specially coded on import declarations and thus are not integrated into thisdatabase

Invoices were considered a true statement of shipping contents as we were not able toassess the veracity of the information contained on the invoice Shipment information (dateport of origin and destination port) was collected from the declaration page and speciesand quantity information was tabulated from the associated invoices and catalogued into adatabase Within the trade of live marine organisms re-export information is not recordedand thus could not be assessed here Both manual entry and automated optical characterrecognition (OCR) software (ABBYY FlexiCapture 90) customized for wildlife shipments(Fig 1) were utilized to retrieve the above information from these documents The inputmethod varied with invoice quality and length Manual entry was utilized when invoiceswere of poor quality (blurry speckled darkened fonts less than six point handwritten) orbrief (less than 12 page) whereas all others were read using the OCR software Once allnecessary data were captured species names were verified using World Register of MarineSpecies (WoRMS Editorial Board 2015) FishBase (Froese amp Pauly 2015) and the primaryliterature (Appeltans et al 2011 Froese amp Pauly 2011) We corrected species informationonly when species names were misspelled listed under a junior synonym or listed byonly a common name Species were identified to the greatest taxonomic detail availableOccasionally genera were listed without species (eg lsquoChrysiptera sprsquo) or the specieswas otherwise ambiguous (eg lsquohybrid Acanthurus tangrsquo) In these cases the genus (andall higher-level taxonomic information) would be recorded and the species would berecorded as unknown Genus and species were recorded as unknown when listed onlyby an ambiguous common name (eg lsquocolorful damselrsquo lsquounknown damselrsquo lsquoassorteddamselsrsquo)

In accordance with Rhyne et al (2012) this report focused on major geographic tradeflows the frequency of invoice detail to species-level and how invoice data compared toLEMIS data Invoice data for both fishes and invertebrates were retrieved concurrentlyTo help organize and visualize the trade data a publically accessible representation of thetrade data was created the Marine Aquarium Biodiversity and Trade Flow online database(httpswwwaquariumtradedataorg) This web-based graphical user interface poweredby the open source JavaScript library D3 (httpd3jsorg) is data-rich visually appealingand allows users to query more than 28000 invoices containing over 27 million lines ofinvoice data from 2000 2004 2005 2008 2009 and 2011

To back-calculate the estimated total annual imports of marine animals during yearswith incomplete data sets (years 2000 2004 2005) we first determined the proportion ofindividuals imported during the time interval (one month for 2000 sevenmonths for 2004and five months for 2005) based on the three years for which we had a complete 12-monthdataset (2008 2009 and 2011) For these three years there was variation between monthsbut the intra-month variation was less than that of the inter-month variation suggesting

Rhyne et al (2017) PeerJ DOI 107717peerj2949 536

that monthly import volumes were proportionally consistent This proportion was thenused to calculate the number of individuals for the unknown months using the followingrelation

(nPr)minusn

where n is the known number of imports per year for 1 (2000) 5 (2004) or 7 (2005)months and Pr is the average proportion of known imports from corresponding monthsfrom 2008 2009 and 2011 This estimated number of animals was then allocated across theunknown months proportionally for 2000 2004 and 2005 This method appears robustgiven the consistency of the most voluminous species across years (see results) We alsogenerated estimates for the source countries and ports of entry The database user canselect the type of data to view and within the selection tool can select to view actual dataor whether estimates should be included Even though these numbers are estimates wepresent them as numbers so that they coalesce with the complete database

RESULTSAll data presented in this report are available at theMarineAquariumBiodiversity andTradeFlow online database (httpswwwaquariumtradedataorg) This site was developed toallow users to generate database queries using dropdownmenus On the lsquolsquoHomersquorsquo tab initialqueries can be filtered through large-scale source areas such as ocean basins or countries oforigin for a defined time period (Fig 2) Following user selections the software compilesdetailed information in the form of maps timeline charts and other data charts that allowusers to access data at a depth uncommon in user interfaces for the wildlife or seafoodtrades On further analysis it is possible using the lsquolsquoSpeciesrsquorsquo tab to query a single taxonomicfamily genus or species for one or more countries andor ports of entry The user-friendlydropdown menus are tree-based and progressive Figure 3 demonstrates successive screenswhere the user has successively selected the family Pomacentridae the genus Amphiprionand the species complex Amphiprion perculaocellaris The dashboard displays (A) adistribution map depicting the relative geographic importance using proportionally-sizedred dots and (B C) two graphs displaying export country- and port of entry-specificvolumes for the selected query To enhance the utility of the website and promote thedissemination of the data the user can download charts and graphs of data queries Userscan also share these charts directly to Facebook and Twitter (Fig 4) Further to ensure thedata within the invoice-based database is an accurate representation of the trade users canreport possible errors in data or features on the website If users find species that are likelyincorrect in distribution or taxa we can examine the invoice record verify its contents andupdate the database if needed This system also logs how users interact with the databasewhich provides feedback on the number and types of queries users generated

General trendsIn 2008 a total of 8299467 individual fishes (974 identified to species-level) representing1788 species were imported into the US The total number of fishes imported decreasedto 7102246 in 2009 and to 6892960 in 2011 However the number of species imported

increased to 1798 by 2011 While no more than 1800 species were imported in a singleyear 2278 unique species were imported across the three-year span (Table 1)

A similar trend in the overall trade was observed for non-CITES-listed invertebratesduring this time period although the invertebrate data were less voluminous and speciouscompared to the fish data A total of 43 million invertebrates representing 545 species wereimported into the US in 2008 The total number of invertebrates imported decreased toabout 37 million in 2009 and 2011 (Table 2) A total of 724 species were imported overthe three-year span Compared to fishes relatively fewer invertebrates were identified tospecies-level (729)

Export countriesForty-five countries in total exported marine fishes to the US during the three years(Table 1) with 41 37 and 36 countries noted in 2008 2009 and 2011 respectively ThePhilippines exported 56 of the cumulative total volume (127 million fishes Fig 5)The overall volume of fishes traded decreased by 17 between 2008 and 2011 withcommensurate export decreases from the Philippines and Indonesia Third-ranked SriLanka exported consistently across the three years Exports from fourth-ranked Haitidecreased by nearly 50 between 2008 and 2011 likely due to earthquake activity in 2010

The US imported marine invertebrates from a total of 38 countries during the threeyears (Fig 5 Table 2) although only 27 (2008 2009) or 28 (2011) countries were noted peryear The number of individuals exported per year decreased 14 between 2008 and 2011a rate similar to that of fishes The countries exporting the greatest volume over the threeyears were the Philippines (36 million invertebrates) and Haiti (31 million invertebrates)The number of individual invertebrates exported from the Philippines increased by 24

Figure 5 Trade flow of marine aquarium fishes and invertebrates from source nations into the USduring 2008 2009 and 2011Numbers within circles denote percent contribution to total imports Piechart within US represents Ports of Entry (with the Midwest starting at 0 degrees and clockwise NE SESW and NW)

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

Estimated fishIn October of 2000 810705 fishes and 124308 invertebrates were imported Duringthe years 2008 2009 and 2011 October represented on average 87 of fish and 86of invertebrate imports into the US Thus it can be estimated that 9327754 fish and1442859 invertebrates were imported into the US during calendar year 2000 Followingthis example 10766706 and 11229443 fish were imported into the US in 2004 and 2005respectively no invertebrate data was available for 2004 and 2005 data

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

Species of Wild Fauna and Flora (CITES) However previous studies found that CITESrecords were inaccurate incomplete or insufficient (Bickford et al 2011 Blundell ampMascia 2005 Rhyne et al 2012) Furthermore CITES-listed species (namely stony coralsgiant clams and seahorses) account for only a fraction of the total trade in live aquaticanimals Only a handful of studies (Rhyne et al 2012 Smith et al 2009 Smith et al 2008)have attempted to quantify the movement of non-CITES-listed aquarium species fromsource to market The Global Marine AquariumDatabase (GMAD) encouraged companiesto provide data on the marine aquarium trade (Green 2003) and until now GMAD wasthe only source for aquarium trade data recorded at a species-specific level While GMADcontains trade data from 1988 to 2003 some years and countries (eg Haiti) are missingand values reported in GMAD were found to be drastically fewer than other estimates oftrade data (Murray et al 2012) Furthermore the aquarium trade has been transformedby new technologies and husbandry breakthroughs since 2003 (Rhyne amp Tlusty 2012)which may dilute the relevance of this data set In addition to CITES and GMAD the LawEnforcement Management Information System (LEMIS) database has been used to betterunderstand the aquarium trade The United States Fish and Wildlife Service (USFWS)inspects wildlife shipments and through LEMIS maintains species-specific data in the caseof transporting CITES-listed species per CITES requirements However non-CITES-listedspecies are recorded with general codes (eg marine aquarium tropical fish regardless ofspecies are coded MATF) Recording data in this generalized manner eliminates specificinformation regarding the diversity and volumes of species traded (Smith et al 2009)While the need for accurate accounts of aquarium trade flow continually increases thecurrent monitoring methods remain static (Bickford et al 2011) The lack of specific datasystems for recording all species exported and imported for the marine aquarium traderaises two main concerns (1) because of the lack of trade data it is unclear how importingand exporting governments can monitor this industry effectively (2) it is also unclear howsustainability should be encouraged given the paucity of data

To date Balboa (2003) Wabnitz et al (2003) and Rhyne et al (2012) have cataloguedspecies-specific information provided on trade invoices Rhyne et al (2012) furthercompared invoice information to associated shipment declarations It was this effortthat led to the development of the Marine Aquarium Biodiversity and Trade Flow onlinedatabase (httpswwwaquariumtradedataorg) a public portal offering anonymized livemarine animal trade data collected through trade invoices Here we describe three years(2008 2009 2011) of fish and invertebrate invoice-based data from US imports that wereanalyzed for country of origin port of entry and quantity of species and individualsassociated with each port We also relate the findings from these three years of completetrade data to previously existing invoice-based trade data from the LEMIS databaseSpecifically Rhyne et al (2012) described one contiguous year of import data based on a12-month period from June 2004 (sevenmonths) untilMay 2005 (fivemonths) and Balboa(2003) described one month (October) of data from 2000 To address the missing monthsof data from these years and to increase the scope of the dataset we modeled data for themissing months based on the monthly volume patterns analyzed from the three completeyears of data available (2008 2009 2011) This work provides an enlarged snapshot of the

Rhyne et al (2017) PeerJ DOI 107717peerj2949 336

volume biodiversity and trade pathways for live marine aquarium fish and invertebratespecies beyond the information provided by other reporting systems (Wabnitz et al2003) Further this work demonstrates that LEMIS while well-designed for importexportcompliance and management of USFWS staffing needs is not designed to monitor thespecies-level activity of the live marine aquarium trade Finally we present two casestudies (the Banggai cardinalfish Pterapogon kauderni and the commonorange clownfishAmphiprion ocellarispercula) to demonstrate the use of these data for better understandingthe trade in marine species a first step toward advancing industry sustainability

METHODSThe goal of this project was to evaluate the number of live marine aquarium speciesimported into the US and to create a trade path analysis of the diversity of animalsinvolved in the trade The methods used to analyze trade invoices were described byRhyne et al (2012) and are briefly summarized here We reviewed all USFWS shipmentdeclarations and the attached commercial invoices coded as Marine Aquarium TropicalFish (MATF) for 2008 2009 and 2011 as indicated in the LEMIS database Whileabout 22000 invoices were marked as containing MATF in the LEMIS database wereceived approximately 20000 shipment declarations and their attached invoices CITESdata are specially coded on import declarations and thus are not integrated into thisdatabase

Invoices were considered a true statement of shipping contents as we were not able toassess the veracity of the information contained on the invoice Shipment information (dateport of origin and destination port) was collected from the declaration page and speciesand quantity information was tabulated from the associated invoices and catalogued into adatabase Within the trade of live marine organisms re-export information is not recordedand thus could not be assessed here Both manual entry and automated optical characterrecognition (OCR) software (ABBYY FlexiCapture 90) customized for wildlife shipments(Fig 1) were utilized to retrieve the above information from these documents The inputmethod varied with invoice quality and length Manual entry was utilized when invoiceswere of poor quality (blurry speckled darkened fonts less than six point handwritten) orbrief (less than 12 page) whereas all others were read using the OCR software Once allnecessary data were captured species names were verified using World Register of MarineSpecies (WoRMS Editorial Board 2015) FishBase (Froese amp Pauly 2015) and the primaryliterature (Appeltans et al 2011 Froese amp Pauly 2011) We corrected species informationonly when species names were misspelled listed under a junior synonym or listed byonly a common name Species were identified to the greatest taxonomic detail availableOccasionally genera were listed without species (eg lsquoChrysiptera sprsquo) or the specieswas otherwise ambiguous (eg lsquohybrid Acanthurus tangrsquo) In these cases the genus (andall higher-level taxonomic information) would be recorded and the species would berecorded as unknown Genus and species were recorded as unknown when listed onlyby an ambiguous common name (eg lsquocolorful damselrsquo lsquounknown damselrsquo lsquoassorteddamselsrsquo)

To determine if the volume of captive-bred P kauderni imported into the US hasincreased in recent years we reviewed invoice data from Los Angeles-based importerQuality Marine for two additional recent years of imports Quality Marine sourced fishfrom Thailand and these were known to have been captive-bred given that Thailandlies outside the native range of P kauderni At our request all shipments of MATF fromThailand to Quality Marine over the period of March 2012 to July 2014 were supplied andreviewed

In accordance with Rhyne et al (2012) this report focused on major geographic tradeflows the frequency of invoice detail to species-level and how invoice data compared toLEMIS data Invoice data for both fishes and invertebrates were retrieved concurrentlyTo help organize and visualize the trade data a publically accessible representation of thetrade data was created the Marine Aquarium Biodiversity and Trade Flow online database(httpswwwaquariumtradedataorg) This web-based graphical user interface poweredby the open source JavaScript library D3 (httpd3jsorg) is data-rich visually appealingand allows users to query more than 28000 invoices containing over 27 million lines ofinvoice data from 2000 2004 2005 2008 2009 and 2011

To back-calculate the estimated total annual imports of marine animals during yearswith incomplete data sets (years 2000 2004 2005) we first determined the proportion ofindividuals imported during the time interval (one month for 2000 sevenmonths for 2004and five months for 2005) based on the three years for which we had a complete 12-monthdataset (2008 2009 and 2011) For these three years there was variation between monthsbut the intra-month variation was less than that of the inter-month variation suggesting

Rhyne et al (2017) PeerJ DOI 107717peerj2949 536

that monthly import volumes were proportionally consistent This proportion was thenused to calculate the number of individuals for the unknown months using the followingrelation

(nPr)minusn

where n is the known number of imports per year for 1 (2000) 5 (2004) or 7 (2005)months and Pr is the average proportion of known imports from corresponding monthsfrom 2008 2009 and 2011 This estimated number of animals was then allocated across theunknown months proportionally for 2000 2004 and 2005 This method appears robustgiven the consistency of the most voluminous species across years (see results) We alsogenerated estimates for the source countries and ports of entry The database user canselect the type of data to view and within the selection tool can select to view actual dataor whether estimates should be included Even though these numbers are estimates wepresent them as numbers so that they coalesce with the complete database

RESULTSAll data presented in this report are available at theMarineAquariumBiodiversity andTradeFlow online database (httpswwwaquariumtradedataorg) This site was developed toallow users to generate database queries using dropdownmenus On the lsquolsquoHomersquorsquo tab initialqueries can be filtered through large-scale source areas such as ocean basins or countries oforigin for a defined time period (Fig 2) Following user selections the software compilesdetailed information in the form of maps timeline charts and other data charts that allowusers to access data at a depth uncommon in user interfaces for the wildlife or seafoodtrades On further analysis it is possible using the lsquolsquoSpeciesrsquorsquo tab to query a single taxonomicfamily genus or species for one or more countries andor ports of entry The user-friendlydropdown menus are tree-based and progressive Figure 3 demonstrates successive screenswhere the user has successively selected the family Pomacentridae the genus Amphiprionand the species complex Amphiprion perculaocellaris The dashboard displays (A) adistribution map depicting the relative geographic importance using proportionally-sizedred dots and (B C) two graphs displaying export country- and port of entry-specificvolumes for the selected query To enhance the utility of the website and promote thedissemination of the data the user can download charts and graphs of data queries Userscan also share these charts directly to Facebook and Twitter (Fig 4) Further to ensure thedata within the invoice-based database is an accurate representation of the trade users canreport possible errors in data or features on the website If users find species that are likelyincorrect in distribution or taxa we can examine the invoice record verify its contents andupdate the database if needed This system also logs how users interact with the databasewhich provides feedback on the number and types of queries users generated

General trendsIn 2008 a total of 8299467 individual fishes (974 identified to species-level) representing1788 species were imported into the US The total number of fishes imported decreasedto 7102246 in 2009 and to 6892960 in 2011 However the number of species imported

increased to 1798 by 2011 While no more than 1800 species were imported in a singleyear 2278 unique species were imported across the three-year span (Table 1)

A similar trend in the overall trade was observed for non-CITES-listed invertebratesduring this time period although the invertebrate data were less voluminous and speciouscompared to the fish data A total of 43 million invertebrates representing 545 species wereimported into the US in 2008 The total number of invertebrates imported decreased toabout 37 million in 2009 and 2011 (Table 2) A total of 724 species were imported overthe three-year span Compared to fishes relatively fewer invertebrates were identified tospecies-level (729)

Export countriesForty-five countries in total exported marine fishes to the US during the three years(Table 1) with 41 37 and 36 countries noted in 2008 2009 and 2011 respectively ThePhilippines exported 56 of the cumulative total volume (127 million fishes Fig 5)The overall volume of fishes traded decreased by 17 between 2008 and 2011 withcommensurate export decreases from the Philippines and Indonesia Third-ranked SriLanka exported consistently across the three years Exports from fourth-ranked Haitidecreased by nearly 50 between 2008 and 2011 likely due to earthquake activity in 2010

The US imported marine invertebrates from a total of 38 countries during the threeyears (Fig 5 Table 2) although only 27 (2008 2009) or 28 (2011) countries were noted peryear The number of individuals exported per year decreased 14 between 2008 and 2011a rate similar to that of fishes The countries exporting the greatest volume over the threeyears were the Philippines (36 million invertebrates) and Haiti (31 million invertebrates)The number of individual invertebrates exported from the Philippines increased by 24

Figure 5 Trade flow of marine aquarium fishes and invertebrates from source nations into the USduring 2008 2009 and 2011Numbers within circles denote percent contribution to total imports Piechart within US represents Ports of Entry (with the Midwest starting at 0 degrees and clockwise NE SESW and NW)

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

volume biodiversity and trade pathways for live marine aquarium fish and invertebratespecies beyond the information provided by other reporting systems (Wabnitz et al2003) Further this work demonstrates that LEMIS while well-designed for importexportcompliance and management of USFWS staffing needs is not designed to monitor thespecies-level activity of the live marine aquarium trade Finally we present two casestudies (the Banggai cardinalfish Pterapogon kauderni and the commonorange clownfishAmphiprion ocellarispercula) to demonstrate the use of these data for better understandingthe trade in marine species a first step toward advancing industry sustainability

METHODSThe goal of this project was to evaluate the number of live marine aquarium speciesimported into the US and to create a trade path analysis of the diversity of animalsinvolved in the trade The methods used to analyze trade invoices were described byRhyne et al (2012) and are briefly summarized here We reviewed all USFWS shipmentdeclarations and the attached commercial invoices coded as Marine Aquarium TropicalFish (MATF) for 2008 2009 and 2011 as indicated in the LEMIS database Whileabout 22000 invoices were marked as containing MATF in the LEMIS database wereceived approximately 20000 shipment declarations and their attached invoices CITESdata are specially coded on import declarations and thus are not integrated into thisdatabase

Invoices were considered a true statement of shipping contents as we were not able toassess the veracity of the information contained on the invoice Shipment information (dateport of origin and destination port) was collected from the declaration page and speciesand quantity information was tabulated from the associated invoices and catalogued into adatabase Within the trade of live marine organisms re-export information is not recordedand thus could not be assessed here Both manual entry and automated optical characterrecognition (OCR) software (ABBYY FlexiCapture 90) customized for wildlife shipments(Fig 1) were utilized to retrieve the above information from these documents The inputmethod varied with invoice quality and length Manual entry was utilized when invoiceswere of poor quality (blurry speckled darkened fonts less than six point handwritten) orbrief (less than 12 page) whereas all others were read using the OCR software Once allnecessary data were captured species names were verified using World Register of MarineSpecies (WoRMS Editorial Board 2015) FishBase (Froese amp Pauly 2015) and the primaryliterature (Appeltans et al 2011 Froese amp Pauly 2011) We corrected species informationonly when species names were misspelled listed under a junior synonym or listed byonly a common name Species were identified to the greatest taxonomic detail availableOccasionally genera were listed without species (eg lsquoChrysiptera sprsquo) or the specieswas otherwise ambiguous (eg lsquohybrid Acanthurus tangrsquo) In these cases the genus (andall higher-level taxonomic information) would be recorded and the species would berecorded as unknown Genus and species were recorded as unknown when listed onlyby an ambiguous common name (eg lsquocolorful damselrsquo lsquounknown damselrsquo lsquoassorteddamselsrsquo)

To determine if the volume of captive-bred P kauderni imported into the US hasincreased in recent years we reviewed invoice data from Los Angeles-based importerQuality Marine for two additional recent years of imports Quality Marine sourced fishfrom Thailand and these were known to have been captive-bred given that Thailandlies outside the native range of P kauderni At our request all shipments of MATF fromThailand to Quality Marine over the period of March 2012 to July 2014 were supplied andreviewed

In accordance with Rhyne et al (2012) this report focused on major geographic tradeflows the frequency of invoice detail to species-level and how invoice data compared toLEMIS data Invoice data for both fishes and invertebrates were retrieved concurrentlyTo help organize and visualize the trade data a publically accessible representation of thetrade data was created the Marine Aquarium Biodiversity and Trade Flow online database(httpswwwaquariumtradedataorg) This web-based graphical user interface poweredby the open source JavaScript library D3 (httpd3jsorg) is data-rich visually appealingand allows users to query more than 28000 invoices containing over 27 million lines ofinvoice data from 2000 2004 2005 2008 2009 and 2011

To back-calculate the estimated total annual imports of marine animals during yearswith incomplete data sets (years 2000 2004 2005) we first determined the proportion ofindividuals imported during the time interval (one month for 2000 sevenmonths for 2004and five months for 2005) based on the three years for which we had a complete 12-monthdataset (2008 2009 and 2011) For these three years there was variation between monthsbut the intra-month variation was less than that of the inter-month variation suggesting

Rhyne et al (2017) PeerJ DOI 107717peerj2949 536

that monthly import volumes were proportionally consistent This proportion was thenused to calculate the number of individuals for the unknown months using the followingrelation

(nPr)minusn

where n is the known number of imports per year for 1 (2000) 5 (2004) or 7 (2005)months and Pr is the average proportion of known imports from corresponding monthsfrom 2008 2009 and 2011 This estimated number of animals was then allocated across theunknown months proportionally for 2000 2004 and 2005 This method appears robustgiven the consistency of the most voluminous species across years (see results) We alsogenerated estimates for the source countries and ports of entry The database user canselect the type of data to view and within the selection tool can select to view actual dataor whether estimates should be included Even though these numbers are estimates wepresent them as numbers so that they coalesce with the complete database

RESULTSAll data presented in this report are available at theMarineAquariumBiodiversity andTradeFlow online database (httpswwwaquariumtradedataorg) This site was developed toallow users to generate database queries using dropdownmenus On the lsquolsquoHomersquorsquo tab initialqueries can be filtered through large-scale source areas such as ocean basins or countries oforigin for a defined time period (Fig 2) Following user selections the software compilesdetailed information in the form of maps timeline charts and other data charts that allowusers to access data at a depth uncommon in user interfaces for the wildlife or seafoodtrades On further analysis it is possible using the lsquolsquoSpeciesrsquorsquo tab to query a single taxonomicfamily genus or species for one or more countries andor ports of entry The user-friendlydropdown menus are tree-based and progressive Figure 3 demonstrates successive screenswhere the user has successively selected the family Pomacentridae the genus Amphiprionand the species complex Amphiprion perculaocellaris The dashboard displays (A) adistribution map depicting the relative geographic importance using proportionally-sizedred dots and (B C) two graphs displaying export country- and port of entry-specificvolumes for the selected query To enhance the utility of the website and promote thedissemination of the data the user can download charts and graphs of data queries Userscan also share these charts directly to Facebook and Twitter (Fig 4) Further to ensure thedata within the invoice-based database is an accurate representation of the trade users canreport possible errors in data or features on the website If users find species that are likelyincorrect in distribution or taxa we can examine the invoice record verify its contents andupdate the database if needed This system also logs how users interact with the databasewhich provides feedback on the number and types of queries users generated

General trendsIn 2008 a total of 8299467 individual fishes (974 identified to species-level) representing1788 species were imported into the US The total number of fishes imported decreasedto 7102246 in 2009 and to 6892960 in 2011 However the number of species imported

increased to 1798 by 2011 While no more than 1800 species were imported in a singleyear 2278 unique species were imported across the three-year span (Table 1)

A similar trend in the overall trade was observed for non-CITES-listed invertebratesduring this time period although the invertebrate data were less voluminous and speciouscompared to the fish data A total of 43 million invertebrates representing 545 species wereimported into the US in 2008 The total number of invertebrates imported decreased toabout 37 million in 2009 and 2011 (Table 2) A total of 724 species were imported overthe three-year span Compared to fishes relatively fewer invertebrates were identified tospecies-level (729)

Export countriesForty-five countries in total exported marine fishes to the US during the three years(Table 1) with 41 37 and 36 countries noted in 2008 2009 and 2011 respectively ThePhilippines exported 56 of the cumulative total volume (127 million fishes Fig 5)The overall volume of fishes traded decreased by 17 between 2008 and 2011 withcommensurate export decreases from the Philippines and Indonesia Third-ranked SriLanka exported consistently across the three years Exports from fourth-ranked Haitidecreased by nearly 50 between 2008 and 2011 likely due to earthquake activity in 2010

The US imported marine invertebrates from a total of 38 countries during the threeyears (Fig 5 Table 2) although only 27 (2008 2009) or 28 (2011) countries were noted peryear The number of individuals exported per year decreased 14 between 2008 and 2011a rate similar to that of fishes The countries exporting the greatest volume over the threeyears were the Philippines (36 million invertebrates) and Haiti (31 million invertebrates)The number of individual invertebrates exported from the Philippines increased by 24

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

Rhyne et al (2017) PeerJ DOI 107717peerj2949 2936

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

Figure 1 FlexiCapture 90 verification screen used to capture shipping data for the wwwaquariumtradedataorg database (A) Shipping decla-ration (B) shipping invoice (C) invoice table produced from Optimal Character Recognition (OCR) software Note grey shaded cells indicate au-tocorrected fields and red flags within cells indicate errors for user to correct manually

To determine if the volume of captive-bred P kauderni imported into the US hasincreased in recent years we reviewed invoice data from Los Angeles-based importerQuality Marine for two additional recent years of imports Quality Marine sourced fishfrom Thailand and these were known to have been captive-bred given that Thailandlies outside the native range of P kauderni At our request all shipments of MATF fromThailand to Quality Marine over the period of March 2012 to July 2014 were supplied andreviewed

In accordance with Rhyne et al (2012) this report focused on major geographic tradeflows the frequency of invoice detail to species-level and how invoice data compared toLEMIS data Invoice data for both fishes and invertebrates were retrieved concurrentlyTo help organize and visualize the trade data a publically accessible representation of thetrade data was created the Marine Aquarium Biodiversity and Trade Flow online database(httpswwwaquariumtradedataorg) This web-based graphical user interface poweredby the open source JavaScript library D3 (httpd3jsorg) is data-rich visually appealingand allows users to query more than 28000 invoices containing over 27 million lines ofinvoice data from 2000 2004 2005 2008 2009 and 2011

To back-calculate the estimated total annual imports of marine animals during yearswith incomplete data sets (years 2000 2004 2005) we first determined the proportion ofindividuals imported during the time interval (one month for 2000 sevenmonths for 2004and five months for 2005) based on the three years for which we had a complete 12-monthdataset (2008 2009 and 2011) For these three years there was variation between monthsbut the intra-month variation was less than that of the inter-month variation suggesting

Rhyne et al (2017) PeerJ DOI 107717peerj2949 536

that monthly import volumes were proportionally consistent This proportion was thenused to calculate the number of individuals for the unknown months using the followingrelation

(nPr)minusn

where n is the known number of imports per year for 1 (2000) 5 (2004) or 7 (2005)months and Pr is the average proportion of known imports from corresponding monthsfrom 2008 2009 and 2011 This estimated number of animals was then allocated across theunknown months proportionally for 2000 2004 and 2005 This method appears robustgiven the consistency of the most voluminous species across years (see results) We alsogenerated estimates for the source countries and ports of entry The database user canselect the type of data to view and within the selection tool can select to view actual dataor whether estimates should be included Even though these numbers are estimates wepresent them as numbers so that they coalesce with the complete database

General trendsIn 2008 a total of 8299467 individual fishes (974 identified to species-level) representing1788 species were imported into the US The total number of fishes imported decreasedto 7102246 in 2009 and to 6892960 in 2011 However the number of species imported

increased to 1798 by 2011 While no more than 1800 species were imported in a singleyear 2278 unique species were imported across the three-year span (Table 1)

A similar trend in the overall trade was observed for non-CITES-listed invertebratesduring this time period although the invertebrate data were less voluminous and speciouscompared to the fish data A total of 43 million invertebrates representing 545 species wereimported into the US in 2008 The total number of invertebrates imported decreased toabout 37 million in 2009 and 2011 (Table 2) A total of 724 species were imported overthe three-year span Compared to fishes relatively fewer invertebrates were identified tospecies-level (729)

Export countriesForty-five countries in total exported marine fishes to the US during the three years(Table 1) with 41 37 and 36 countries noted in 2008 2009 and 2011 respectively ThePhilippines exported 56 of the cumulative total volume (127 million fishes Fig 5)The overall volume of fishes traded decreased by 17 between 2008 and 2011 withcommensurate export decreases from the Philippines and Indonesia Third-ranked SriLanka exported consistently across the three years Exports from fourth-ranked Haitidecreased by nearly 50 between 2008 and 2011 likely due to earthquake activity in 2010

The US imported marine invertebrates from a total of 38 countries during the threeyears (Fig 5 Table 2) although only 27 (2008 2009) or 28 (2011) countries were noted peryear The number of individuals exported per year decreased 14 between 2008 and 2011a rate similar to that of fishes The countries exporting the greatest volume over the threeyears were the Philippines (36 million invertebrates) and Haiti (31 million invertebrates)The number of individual invertebrates exported from the Philippines increased by 24

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

Figure 5 Trade flow of marine aquarium fishes and invertebrates from source nations into the USduring 2008 2009 and 2011Numbers within circles denote percent contribution to total imports Piechart within US represents Ports of Entry (with the Midwest starting at 0 degrees and clockwise NE SESW and NW)

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

Estimated fishIn October of 2000 810705 fishes and 124308 invertebrates were imported Duringthe years 2008 2009 and 2011 October represented on average 87 of fish and 86of invertebrate imports into the US Thus it can be estimated that 9327754 fish and1442859 invertebrates were imported into the US during calendar year 2000 Followingthis example 10766706 and 11229443 fish were imported into the US in 2004 and 2005respectively no invertebrate data was available for 2004 and 2005 data

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

Export countriesForty-five countries in total exported marine fishes to the US during the three years(Table 1) with 41 37 and 36 countries noted in 2008 2009 and 2011 respectively ThePhilippines exported 56 of the cumulative total volume (127 million fishes Fig 5)The overall volume of fishes traded decreased by 17 between 2008 and 2011 withcommensurate export decreases from the Philippines and Indonesia Third-ranked SriLanka exported consistently across the three years Exports from fourth-ranked Haitidecreased by nearly 50 between 2008 and 2011 likely due to earthquake activity in 2010

The US imported marine invertebrates from a total of 38 countries during the threeyears (Fig 5 Table 2) although only 27 (2008 2009) or 28 (2011) countries were noted peryear The number of individuals exported per year decreased 14 between 2008 and 2011a rate similar to that of fishes The countries exporting the greatest volume over the threeyears were the Philippines (36 million invertebrates) and Haiti (31 million invertebrates)The number of individual invertebrates exported from the Philippines increased by 24

Figure 5 Trade flow of marine aquarium fishes and invertebrates from source nations into the USduring 2008 2009 and 2011Numbers within circles denote percent contribution to total imports Piechart within US represents Ports of Entry (with the Midwest starting at 0 degrees and clockwise NE SESW and NW)

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

Estimated fishIn October of 2000 810705 fishes and 124308 invertebrates were imported Duringthe years 2008 2009 and 2011 October represented on average 87 of fish and 86of invertebrate imports into the US Thus it can be estimated that 9327754 fish and1442859 invertebrates were imported into the US during calendar year 2000 Followingthis example 10766706 and 11229443 fish were imported into the US in 2004 and 2005respectively no invertebrate data was available for 2004 and 2005 data

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

Export countriesForty-five countries in total exported marine fishes to the US during the three years(Table 1) with 41 37 and 36 countries noted in 2008 2009 and 2011 respectively ThePhilippines exported 56 of the cumulative total volume (127 million fishes Fig 5)The overall volume of fishes traded decreased by 17 between 2008 and 2011 withcommensurate export decreases from the Philippines and Indonesia Third-ranked SriLanka exported consistently across the three years Exports from fourth-ranked Haitidecreased by nearly 50 between 2008 and 2011 likely due to earthquake activity in 2010

The US imported marine invertebrates from a total of 38 countries during the threeyears (Fig 5 Table 2) although only 27 (2008 2009) or 28 (2011) countries were noted peryear The number of individuals exported per year decreased 14 between 2008 and 2011a rate similar to that of fishes The countries exporting the greatest volume over the threeyears were the Philippines (36 million invertebrates) and Haiti (31 million invertebrates)The number of individual invertebrates exported from the Philippines increased by 24

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

Export countriesForty-five countries in total exported marine fishes to the US during the three years(Table 1) with 41 37 and 36 countries noted in 2008 2009 and 2011 respectively ThePhilippines exported 56 of the cumulative total volume (127 million fishes Fig 5)The overall volume of fishes traded decreased by 17 between 2008 and 2011 withcommensurate export decreases from the Philippines and Indonesia Third-ranked SriLanka exported consistently across the three years Exports from fourth-ranked Haitidecreased by nearly 50 between 2008 and 2011 likely due to earthquake activity in 2010

The US imported marine invertebrates from a total of 38 countries during the threeyears (Fig 5 Table 2) although only 27 (2008 2009) or 28 (2011) countries were noted peryear The number of individuals exported per year decreased 14 between 2008 and 2011a rate similar to that of fishes The countries exporting the greatest volume over the threeyears were the Philippines (36 million invertebrates) and Haiti (31 million invertebrates)The number of individual invertebrates exported from the Philippines increased by 24

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

Rhyne et al (2017) PeerJ DOI 107717peerj2949 2936

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

Figure 5 Trade flow of marine aquarium fishes and invertebrates from source nations into the USduring 2008 2009 and 2011Numbers within circles denote percent contribution to total imports Piechart within US represents Ports of Entry (with the Midwest starting at 0 degrees and clockwise NE SESW and NW)

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

Number of species exported per country (log10)

Figure 6 The cumulative summation of the number of (A) fishes and (B) invertebrates exported percountry by rank order of species The most-exported species represents a significant proportion of the to-tal individuals exported per country and this importance decreases as a country exports a greater numberof species

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

Estimated fishIn October of 2000 810705 fishes and 124308 invertebrates were imported Duringthe years 2008 2009 and 2011 October represented on average 87 of fish and 86of invertebrate imports into the US Thus it can be estimated that 9327754 fish and1442859 invertebrates were imported into the US during calendar year 2000 Followingthis example 10766706 and 11229443 fish were imported into the US in 2004 and 2005respectively no invertebrate data was available for 2004 and 2005 data

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

Estimated fishIn October of 2000 810705 fishes and 124308 invertebrates were imported Duringthe years 2008 2009 and 2011 October represented on average 87 of fish and 86of invertebrate imports into the US Thus it can be estimated that 9327754 fish and1442859 invertebrates were imported into the US during calendar year 2000 Followingthis example 10766706 and 11229443 fish were imported into the US in 2004 and 2005respectively no invertebrate data was available for 2004 and 2005 data

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

Figure 5 Trade flow of marine aquarium fishes and invertebrates from source nations into the USduring 2008 2009 and 2011Numbers within circles denote percent contribution to total imports Piechart within US represents Ports of Entry (with the Midwest starting at 0 degrees and clockwise NE SESW and NW)

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

Estimated fishIn October of 2000 810705 fishes and 124308 invertebrates were imported Duringthe years 2008 2009 and 2011 October represented on average 87 of fish and 86of invertebrate imports into the US Thus it can be estimated that 9327754 fish and1442859 invertebrates were imported into the US during calendar year 2000 Followingthis example 10766706 and 11229443 fish were imported into the US in 2004 and 2005respectively no invertebrate data was available for 2004 and 2005 data

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

Figure 5 Trade flow of marine aquarium fishes and invertebrates from source nations into the USduring 2008 2009 and 2011Numbers within circles denote percent contribution to total imports Piechart within US represents Ports of Entry (with the Midwest starting at 0 degrees and clockwise NE SESW and NW)

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

Figure 5 Trade flow of marine aquarium fishes and invertebrates from source nations into the USduring 2008 2009 and 2011Numbers within circles denote percent contribution to total imports Piechart within US represents Ports of Entry (with the Midwest starting at 0 degrees and clockwise NE SESW and NW)

between 2008 and 2011 This was likely a response to the decrease in volume from Haiti(52 decline from 2008 to 2011) Third-ranked Indonesia (18 million invertebrates)exported a consistent volume across the three years Even though Indonesia ranked thirdin volume it exported the most species (413) during the three years The Philippines (395)and Sri Lanka (87) were second and third respectively in terms of the number of speciesexported to the US

SpeciesMore than half (52) of the total fishes imported into the US (identified to species-levelTable 3) were represented by 20 species There was a great deal of consistency within thesetop 20 species among the years of this study The species ranking was identical between

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

Number of species exported per country (log10)

Figure 6 The cumulative summation of the number of (A) fishes and (B) invertebrates exported percountry by rank order of species The most-exported species represents a significant proportion of the to-tal individuals exported per country and this importance decreases as a country exports a greater numberof species

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

Estimated fishIn October of 2000 810705 fishes and 124308 invertebrates were imported Duringthe years 2008 2009 and 2011 October represented on average 87 of fish and 86of invertebrate imports into the US Thus it can be estimated that 9327754 fish and1442859 invertebrates were imported into the US during calendar year 2000 Followingthis example 10766706 and 11229443 fish were imported into the US in 2004 and 2005respectively no invertebrate data was available for 2004 and 2005 data

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

Estimated fishIn October of 2000 810705 fishes and 124308 invertebrates were imported Duringthe years 2008 2009 and 2011 October represented on average 87 of fish and 86of invertebrate imports into the US Thus it can be estimated that 9327754 fish and1442859 invertebrates were imported into the US during calendar year 2000 Followingthis example 10766706 and 11229443 fish were imported into the US in 2004 and 2005respectively no invertebrate data was available for 2004 and 2005 data

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

2008 and 2009 and only the 20th ranked fish was different in 2011 (the blueband gobyValenciennea strigata replaced the royal gramma Gramma loreto) The order of the topseven fish species was consistent across the years and represented nearly 33 of total fishimports The green chromis Chromis viridis was the most popular fish species across allthree years (gt10 of total fish imports) and was exported by 13ndash16 different countriesdepending on the year This Chromis species was unique in being collected from a largenumber of countries The only other fish that was equally sourced from a large number ofcountries (an average of 15 per year) was the blue tang Paracanthurus hepatus (Table 3)

Invertebrates demonstrated a similar but more extreme trend The top 20 species ofinvertebrates imported into theUSwere responsible for approximately 75of total imports(identified to species-level Table 3) yet there was more variability in the invertebrate top20 species list compared to the fish list Only the top two species (the scarlet hermitcrab Paguristes cadenati and the scarlet skunk cleaner shrimp Lysmata amboinensis) wereconsistently ranked across the three years Overall 25 invertebrate species were representedon the three yearly top 20 lists (Table 3)

Each country could be represented by a single most exported species Overall the singlemost imported species averaged 37 (fishes) or 63 (invertebrates) of total species volumeexported from that country (Tables 4 and 5) In general countries that exported greaterquantities of marine animals relied less on the contribution of the single most importantspecies to export volume (Fig 6)

Comparison to LEMIS dataThe LEMIS database contains information regarding non-CITES-listed species recordedon declarations under general codes LEMIS data is produced by US-based importersfrom shipment declarations where importers input shipment data into the required 3-177declaration form and present the completed shipment declaration with correspondinginvoice to USFWS prior to shipment clearance We have demonstrated elsewhere (Rhyne etal 2012) that this method of gathering import data is fraught with errors first importerscommonly mislabel shipments as containing marine aquarium species when they onlycontain freshwater fish non-marine species or non-aquarium fish (all increasing the totalnumber of fish reported in the LEMIS database) second the data do not appear to beupdated if shipments are canceled or modified (there is sometimes a significant mismatchbetween the number of individuals on the declaration and the corresponding values onthe invoices) third importers commonly misrepresent the country of origin and source(wild-caughtcaptive-bred) of species in shipments As previously discussed (Rhyne ampTlusty 2012) LEMIS is a tool designed for internal use by USFWS primarily relating tovolume of boxes arriving at ports and CITES compliance Shipments of non-CITES-listedspecies andor unregulated species are not held to any data integrity standards We proposethat the invoice-based method of data collection presented here can rectify many of thedata deficiency issues that currently exist within the marine aquarium trade Through thiswork it was observed that the numbers of fishes imported into the US were routinely60ndash72 fewer than the import volumes reported by the LEMIS database (Fig 7) A largeproportion of the declaration form overestimate was a result of importers misclassifying

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

Estimated fishIn October of 2000 810705 fishes and 124308 invertebrates were imported Duringthe years 2008 2009 and 2011 October represented on average 87 of fish and 86of invertebrate imports into the US Thus it can be estimated that 9327754 fish and1442859 invertebrates were imported into the US during calendar year 2000 Followingthis example 10766706 and 11229443 fish were imported into the US in 2004 and 2005respectively no invertebrate data was available for 2004 and 2005 data

Figure 8 Annual volume of Bangaii cardinalfish (Pterapogon kauderni) into the US by top exportcountries Exports from Sri Lanka (2009 2011) and Thailand (2013) illustrate the likely prevalence ofpreviously unrecognized captive-bred P kauderni in the trade

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

Rhyne et al (2017) PeerJ DOI 107717peerj2949 2936

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

Rhyne et al (2017) PeerJ DOI 107717peerj2949 2936

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

shipments as MATF when they only contained freshwater species Occasionally entirefreshwater shipments were erroneously listed as MATF A second unknown portion ofthis error was missing invoices Not all invoices were recovered from the LEMIS systemSeveral hundred records were either missing the invoice or exhibited invoicedeclarationmismatch making the data impossible to verify Similarly invoice-based data reporteda total of 45 countries exporting MATF which was only 60 of the 76 export countriesreported by the LEMIS database (Table 6) These countries represented 5 6 and 11of the total volume of MATF imported into the US according to the LEMIS databaseduring 2008 2009 and 2011 respectively (Table 6) Third is that the declaration is typicallycompleted days before the order is packed which invites variation between estimated andactual order volume Finally there was a lack of adherence to differentiating lsquolsquowild-caughtrsquorsquoand lsquolsquocaptive-bredrsquorsquo animals (Rhyne Tlusty amp Kaufman 2012) The case studies presentedbelow use the invoice-based dataset to shed light on this discrepancy

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

Rhyne et al (2017) PeerJ DOI 107717peerj2949 2936

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

CONFUSION BETWEEN ldquoWILDrdquo AND ldquoCULTUREDrdquoPRODUCTIONThe Banggai cardinalfish Pterapogon kauderni is a popular marine fish in the aquariumtrade (ranked the 10th 11th and 8th most imported fish into the US during 2008 2009and 2011 Table 5) It was one of the original marine aquarium aquaculture success stories(Talbot et al 2013 Tlusty 2002) which was supposed to reduce the need for wild-caughtfishes While aquaculture should dominate the source of the fish all P kauderni importedduring this three-year span were reported as wild-caught fish Yet import records from SriLanka in 2009 and 2011 and Thailand in 2013 (both outside the natural geographic rangeof P kauderni) suggest this is not the case (Fig 8)

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Figure 9 Temporal variability of the volume of captive-bred Bangaii cardinalfish (Pterapogon kaud-erni) imported into the US Temporal variability of the volume of assumed captive-bred Bangaii cardi-nalfish (Pterapogon kauderni) imported into Los Angeles California US This seasonal variability is con-sistent with the import of wild fish

The export volume of P kauderni from Thailand followed the typical aquarium tradepattern of lower volumes exported in the summer months (JunendashAugust) and in December(Fig 9) Interestingly in 2013 the only year with a 12-month data set starting in Januaryand ending in December the volume of P kauderni (sim120000 individualsyear) wasapproximately 75 of the average total import volume of this species recorded per yearfor 2008 2009 or 2011 Further these fish were listed on import declarations as rangingin size from 1 to 15 inches A 1-inch fish is smaller than the average wild-caught fish (ARhyne pers obs 2013) and instead represents the typical shipping size of a captive-bredfish Shipment manifests also list the number of Dead On Arrival (DOA) from previousshipments which were extremely low (lt05) for wild-caught P kauderni

The shipment manifests have common errors that can be observed on the 3ndash177 USFWSdeclarations On several occasions the importer incorrectly indicated that shipments werewild-caught animals (lsquolsquoWrsquorsquo) After examining the invoices and associated documents (iehealth and aquaculture certificates) we determined that all shipments of P kauderni fromThailand to Quality Marine during the period examined were captive-bred (lsquolsquoCrsquorsquo) and theimporter erroneously selected lsquolsquoWrsquorsquo in the Source box (Box 18B 3ndash177 form) Given thecurrent Endangered Species Act (ESA) listing for P kauderni (NOAA 2014) accurate andtimely trade data are crucial to the sustainable management of this species

MISIDENTIFICATION AND UNKNOWN TRADESimilar to the Banggai cardinalfish clownfishes exported from Southeast Asia arecommonly labeled as wild-caught while many are in fact captive-bred This inaccuracy iscompounded by the misidentification of clownfishes on export invoices especially amongspecies with similar morphological appearances (eg the orange clownfish Amphiprionpercula and the common clownfishA ocellaris) Use of httpwwwaquariumtradedataorgnot only sheds light on source-errors (as seen in the Banggai cardinalfish case study) butalso on potential species misidentifications

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Figure 10 Imports of orange clownfish (Amphiprion ocellarisA percula) into the US aggregated over2008 2009 and 2011 Export countries were grouped based on the documented geographic range of eachspecies All non-native individuals are either actually native (but of an unknown distribution) captive-bred or misidentified as to origin on the shipping invoice

Recently the orange clownfish (A percula) was proposed to be listed as threatened orendangered under the ESA mainly due to its small geographic distribution and obligaterelationship with giant sea anemones prone to bleaching events in the Coral TriangleHowever the proposition was also based on the assumption that out of the 400000individuals from the perculaocellaris complex imported into the US in 2005 (Rhyne etal 2012) (a) all specimens were wild-caught and (b) A percula and A ocellaris wereequally traded with 200000 individuals of each species being harvested Utilization ofhttpwwwaquariumtradedataorg can help clarify issues regarding origination of thesespeciesWhile in 2008 2009 and 2011 831398 individual clownfishes of the perculaocellariscomplex were imported into the US (Fig 10) only 163547 individuals were A percula(245 Fig 10) These data suggest that the original assumptions of trade volume used topetition for ESA listing were strongly overestimated

Further the Countries of Origin feature of the database revealed that of the ten exportcountries of A percula seven countries (41 of all individuals) fall outside the naturalgeographic range of this species (Fautin amp Allen 1997 Froese amp Pauly 2015) Furthermorefive of the seven non-native locations are established producers of captive-bred A perculaBased on this 7 of the non-native individuals are likely captive-bred specimens Theremaining two non-native countries (Singapore and the Philippines) account for theresidual 93 of the non-native individuals and are likely misidentifications Interestinglyboth Singapore and the Philippines fall within the natural geographic range of A ocellariswhich is commonly confused withA percula While these individuals may bemisidentifiedit is also important to note that Singapore is a known trans-shipping country and couldhave imported their specimens from another country making the true origin of thesespecimens unattainable Furthermore Singapore is a leader in captive-bred production ofaquarium fish and thus many clownfish could be of captive-bred origin

In summary 41 of A percula imported into the US over the three-year span (a)were misidentified as to species or export country (b) were misidentified as to source(wild-caught versus captive-bred) or (c) represent a recently expanded home range not yetnoted within the scientific literature (unlikely) Regardless of the reason the contribution

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3036

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3136

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

Rhyne et al (2017) PeerJ DOI 107717peerj2949 3236

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach

of A percula imports to the perculaocellaris complex is not only substantially less thanassumed but also is likely even lower based on the high percent of geographic anomaliesreported here Ultimately this case study confirms the need for more accurate and detailedtrade data such as that provided via httpwwwaquariumtradedataorg for any potentialESA listing activity

The orange clownfish case study demonstrates the effect that species-level nomenclatureconfusion can have on trade data Users of httpwwwaquariumtradedataorg haveilluminated other examples of species misidentification such as Centropyge argi anAtlantic species (Froese amp Pauly 2015) with a significant volume of reported exports fromIndonesia While species-level confusion may be common for specious genera of fishessuch as Centropyge and Amphiprion it is important to recognize instances of more blatantmisidentification For example the iconic yellow tang Zebrasoma flavescens althougha Hawaiian endemic appears in this database as being exported from 13 countries it isdifficult to imagine this fish being confused with anything else Continuous biogeographicalfiltering of invoice data by website users will help to minimize misidentification errorsOne of the egregious cases of identification error is invoice items listed as lsquolsquounknownrsquorsquoThese must find a home in the database and at this point in time are ultimately listedas lsquolsquoChordatarsquorsquo This lack of identification of fishes raises the issue that different countrieshave various reporting requirements that can create data deficiencies within the databaseIf one queries exports from Hong Kong there are no reporting requirements and thusall fish are entered into the database as the generic category lsquolsquoChordatarsquorsquo A deficiency ofreporting requirements for this database is the lack of between-country agreement

DISCUSSIONThe deficiency of comprehensive and overarching data relating to the global marineaquarium trade hinders progress toward its effective management (Foster Wiswedel ampVincent 2016 Fujita et al 2014Rhyne et al 2012)We believe that access tomore accuratedata will allow for increased public engagement in trade sustainability and guide responsibletrade management These data can stimulate action toward consumer education addresschallenges such as misidentification and better manage species Ideally these will resultin greater sustainability (Tlusty et al 2013) Currently there is no overarching systemfor tracking species-level importexport data for the marine aquarium trade This isexacerbated by the lack of standard recordkeeping between different countries (Green2003) Coupled with this is the fact that present data systems are either overly generalbased on declaration forms (LEMIS) or specific to the trade of rare and threatened species(CITES Foster Wiswedel amp Vincent 2016) The Global Marine AquariumDatabase (Green2003) attempted to make sense of some of these discrepancies but can be difficult to usedue to its data structures and relational databases These complications and data limitationspromote misinterpretation as evidenced by the trade volume under- and over-estimatesdiscussed here Changes to and standardization of the way live animal trade data arerecorded are necessary to accurately assess trade pathways and data inaccuracies This willavoid misinterpretations with potentially costly consequences of social economic and

ecological proportions (eg the use of such data to affect ESA listing status) Such costswill only be exacerbated as the aquarium industry continues to grow

Capturing invoice-based data can waylay many of the deficiencies of the extant databasesand should prove useful to both conservation organizations and government agencies byhelping to address the aquarium trade data deficiency that currently exists The benefit ofthe more detailed invoice data we focused on here is that it allowed for a truer estimate ofaquatic wildlife trade The recent ESA petitions for both the Banggai cardinalfish (NOAA2014) and the orange clownfish (Maison amp Graham 2015) were proposed based onincorrect trade data and in each of these cases we demonstrated that increased knowledgeof production areas and modalities do not support the underlining trade assumptions ofthese petitions The assumptions of these ESA listings were demonstrated to be erroneousin part due to reported source (wild-caught captive-bred farmed) inaccuracies of shippedanimals For example exporters will often mark farmed corals as wild corals even whenthey have proper CITES permits for the export of farmed corals (Rhyne Tlusty amp Kaufman2014) Many exporters do not have the appropriate paperwork or government supportneeded to accurately mark corals as captive-bred or farmed on CITES documents oftenbecause of the onerous process required to certify that corals are of farmed origin Whileimproved analysis of invoices will help limit some of this misreporting it will not be totallyunabated until a full fisheryfarm to retail traceability program is initiated

Further issues with the clownfish ESA listing occurred because of demonstratedgeographic misidentification Seven of the ten export countries of the orange clownfishfell outside the natural geographic range of this species Even though these can beindicated as erroneous data correcting these anomalies is outside the purview ofhttpwwwaquariumtradedataorg as it was deemed important to record data as indicatedon the invoice Further discussion of discrepancy can occur through in-depth analysis ofthese data and such efforts are welcomed As this database develops it will be important toidentify the commonlymisidentified species and to help the entire trade improve its speciesdocumentation Ideally lists of lsquolook-alikersquo species can be created and machine learningcan be used to derive biogeographically edited species lists One of the critical assumptionsof this work is that the invoice represents the true contents of the shipment There are anumber of reasons this may not be the case including but not limited to miscountingmisidentification and intentional substitution The question of invoice veracity has beenhighlighted by others (Jones 2008 Wabnitz et al 2003) and without a study directlycomparing invoice to box contents the exact correlation will remain unknown If it isassumed that the trade is based on above-board honest business practices then the invoiceshould be an accurate representation of the trade However the greater the dishonesty inthe trade (eg invoicing a shipment of corals as MATF) the greater the disconnect betweeninvoice and box contents This project was recently named a Grand Prize Winner of theWildlife Crime Tech Challenge (wwwwildlifecrimetechorg) which will spur continueddevelopment of this project with an emphasis on increasing honest business practices bymore easily identifying and enforcing illegal and inaccurate trade activity

The development of httpwwwaquariumtradedataorg is a first step toward improvingthe data which will allow for better management and oversight of the trade in marine

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

aquatic animals However the invoice analysis was developed from a post-importstandpoint The shipments were accepted at import the paperwork processed and theinvoices stored only to be recovered from storage and delivered for analysis within thisprogram However the OCR data processing has the potential to be utilized in real timeThis would allow for shipment diagnostics to be conducted which could potentiallyidentify misidentified or even illegal shipments Such an import risk-based screen toolexists under the FDArsquos Predictive Risk-based Evaluation for Dynamic Import ComplianceTargeting program (httpwwwfdagovForIndustryImportProgramucm172743htm)and we propose that a similar model would be effective for the aquatic wildlife tradeUltimately such an analysis would provide support to port agents to help them moreeffectively monitor the trade

Aquaculture is a significant means of fish production (Tlusty 2002) This will presenta challenge because the lack of reporting for domestic sales will obscure patterns in thetradeMurray amp Watson (2014) observed clownfish to be the most popular species kept byaquarists although they were not the most popular species imported in our database TheUS domestic production will obscure the relationship between fishes imported and thoseactually being kept by hobbyists However we need to step towards greater recordkeepingon species in the trade and while we focus on international trade it would be ideal ifrecords of domestic production could additionally be kept

While it was not implicitly necessary to estimate the number of individuals importedfor years of incomplete data (2000 2004 and 2005) incomplete data in 2004 and 2005compared to complete data in the later years could give the impression the trade wasincreasing A common query without the estimated number of fish would result in a figurewhere the total number of indivudals in 2000 was 8 while 2004 and 2005 data wouldbe approximately half that of 2008 2009 and 2011 Therefore the estimated fish numberswere calculated to create a more cohesive visual presentation of data and to avoid theincorrect analysis that numbers of US imports of marine aquarium fishes and invertebratesare increasing Prior analysis indicated the trade has decreased from its peak in 2005following the economic recession and a shift to smaller tank sizes (Rhyne amp Tlusty 2012Rhyne Tlusty amp Kaufman 2012) Estimated data should be treated with caution given their(by definition) degree of error We encourage users of this database to determine if moresufficient methods to estimate unknown data can be validated

In summary wildlife data tracking systems require improvement (Chan et al 2015Foster Wiswedel amp Vincent 2016) we are beyond the age of tracking animal shipmentvolume solely for the purpose of assessing port agent staffing needs The systems currentlyin place for tracking non-CITES-listed aquarium animals have proven ineffective inproducing meaningful data that can move the trade toward sustainability and conservation(Vincent et al 2014) The invoice-based dataset presented here while set up as a post-import assessment tool could be easily modified into a real-time aquarium trade datamonitoring system Ideally this can have a positive impact on increasing the veracity of theLEMIS system It behooves the largest aquatic wildlife importer in the world to showcasereal constructive intent to foster sustainability in the trade and to create positive changein an important industry This proof that the trade can be passivily monitored (Wallace

et al 2014) is a huge step toward driving positive change in the trade The next stepwill be to monitor aquarium trade pathways in real-time as this is crucial to effectivelyassist the management of the trade of marine aquarium wildlife for the home aquariumindustry A goal for real-time simultaenous monitoring of exports and imports is nowwithin reach
