Note on subspecies in ichthyology

• No more subspecies in ichthyology … PLEASE

• Issues in matching name in GBIF, and IUCN

• Remains a number of subspecies in FishBase: to be treated case by case

• Number of discrepancies between FB and CofF are due to subspecies issues

Genetics Species

Barcode: some studies in progress

• Brazil: Potentially 3,7 times more spp. identified through barcode than morphologically recognized (Oliveira, FishBoL Conf. 2012);

• Kenya: 3 times more (Nyingi, Bart et coll. TDWG Conf. 2013)

• France: Gobio sp. 1 4 spp. (Kottelat, Doadrio et al.); Confirmed by barcode (Denys)

• West Africa: Hepsetus 1 sp. 4/5 spp. separated by basins from Senegal to Gabon Decru, Vreven et coll.)

Maps from IUCN

Consequences

• Estimation of number of spp.:33,000 valid spp. today

(7,500 exploited, 22.5%)

3 times more potentially with Barcode

Should we expect 100,000 spp. in final ???

• Flaws in this estimation: – “Potential” not confirmed yet;– Only in freshwaters (but think about Mugil cephalus

that could be a complex 14 different spp. around the world; Durand et coll.)

Taxonomy matters

• If 100,000 spp. 22,500 species are potentially exploitable (using the same current ratio 33,000 spp. with 7,500 exploited)

• Some are already exploited,but we did not know they were different spp.or worse, we still don’t know

• Consequences for biodiversity management both for exploitation and conservation

Species Genetics

Species Genetics

Fisheries

• 4,661 spp. used from subsistence to industrial fisheries: 270 stocks with info in FB.

• Characterize populations/stocks (population dynamics parameters)

• Population/stocks are trans-boundary• Analysis of global trends

(“Fishing down marine food webs”) at species rank only

• Need for documentation in accessible databases required

Aquaculture

• 364 farmed spp.: 74 strain stocks in FB.• Characterize strains• Characterize populations/stocks (growth

parameters, disease resistance, environmental plasticity) as genetic ressource

• GIFT tilapia: result of hybridization of wild populations. Will it still possible in the future for other commodities?

• The agriculture community has still to fully recognize that genetic resources matters also for aquatic environment (not only cattle, plants, forest, bacteria)

Population/Genetic “rank”

“Rank” “Stock” # Spp #cultured strain 74 8

hybrid 10 6subspecies 51 30wild stock/population 270 91

… for 125 species …

Different goals between fresh and marine water

• In freshwater basins, interest will be in characterizing species and populations for potential farming.

• while in the sea the main focus will be on characterizing population and stocks for adapted catch fisheries management plans.

Genetics and climate change

• Which species are the winners?Which ones the loosers?

• Hotspots• Requires a database at regional/global levels

to refine the prediction crudly based on occurrences and environmental parameters (so-called niche-modeling)

2010

2050

23 hotspots in Coral Triangle seas in 20102010

29 hotspots in Coral Triangle seas in 20502050

Adaptation to climate change

• Depends on genetics diversity• For example, for respiration and digestion

systems that impact growth• Use phylogeography linked to genetic diversity

analysis• Requires databases linking traits and genes• Extend the predictions only based on

occurrences and environmental parameters (so-called niche-modeling)

Documenting Aquatic Genetic Resources(AqGR)

A global database for Aquatic Genetic Resources

• CGFRA: Commission on Genetic Resources for Food and Agriculture (FAO) [SGRP, INGA, SINGER, …]

• Aquatic organisms barely recognized as animals (or all gathered under “fish”)

• No global database like for cattle, crops, …• Rejection by the commission of all projects

submitted for the past 20 years (last attempt in 2013)

Preparing the Status of the World of the AqGR

• Strengthening national data compilation capacity• Implement a correct framework for data sharing

– National and international standard procedures– Training on standard operating procedures– Improvement of FAO databases– Improvement of AqGR resource identification at

species level– Improvement and linking to the ongoing efforts to

the FAO fisheries and aquaculture questionnaires

Preparing the Status of the World of the AqGR

• Provision of additional resources to key databases for AqGR• Additional capacity building opportunities in data handling, archiving,

collation and dissemination.• Compilation of scattered information on AqGR through expert

consultancies• Standardization of the collection of primary and secondary data• Development of key targets and indicators necessary to determine the

effectiveness of actions and to monitor progress in tracking the state of the world’s AqGR

• Targeted introductions of changes to data collections to industry sectors or countries of particular importance (e.g. because of the volume of production or trade, the threatened nature of the resource, or particular lack of information).

• Specific actions to collate information in areas for which information in existing databases is inadequate.

Suggestions

• Data are scattered in many publications:It requires a massive effort for data entry

• FishBase and SeaLifeBase are structured to accommodate population/genetics entries (See poster on FB data encoding training)

• Advocacy for AqGR to your national delegate in FAO

• Start by regional scale in addition to national like in Portugal

Conclusions

Exploitation and conservation must be balanced for sustainable fish food supply.

Dedicated information systems such as FishBase are fundamental for reaching this goal for the biodiversity part.

Remains to link to socio-economics systems.

A key issue is education at all level of society.
