KING CRAB, SHRIMP, AND BOTTOM FISHEXPLORATIONS FROM SHUMAGIN ISLANDS TO

UNALASKA, ALASKA - SUMMER AND FALL, 1957

By Harold C. Johnson*

SUMMARY

Exploratory fishing to determine the availability and abundance of "king crab,shrimp, and bottom fish in certain waters from the Shumagin Islands to Unalaska,Alaska, was conducted by the U. S. Bureau of Commercial Fisheries from July 18to October 1, 1957. The M/V Tordenskjold, a Seattle commercial trawler, waschartered with Saltonstall-Kennedy Act funds for the work.

A variety of fishing gear was used, including circular and rectangular king­crab pots, large-mesh otter trawls, and a Gulf of Mexico-type shrimp trawl.

During the invest~gations, 61 ot.ter-trawl drags and 36 shrimp trawl drags weremade and 534 individual king-crab pots were set.

Fig. 1 - Chartered vessel M/V Tordenskiold.

The best catch of king crab using an otter trawl occurred between Umga andCherni Islands. Other catches of king crabs with the trawl were generally smalland not considered productive enough to warrant commercial exploitation. Local­ities that yielded promising king crab catches while fishing with pots included Step­ovak Bay, Dorenoi Bay, and vicinity, off Chichagof Bay, between Umga and CherniIslands, and Cold Bay.* Fishery Methods and Equipment Specialist, Branch of Exploratory Fishing and Gear Research, Division of Industrial Re­

Excellent catches of shrimp were made using the lined otter trawl and the Gulfof Mexico-type shrimp trawl. Large catches of pink shrimp were made in BalboaBay, Unga Strait, Stepovak Bay, near Sealion Rocks, and in the vicinity of Beaver andPavlof Bays. The best shrimp trawl drag of the cruise produced a catch of 3,800pounds of shrimp in 30 minutes. Anumber of drags were made which yielded shrimp atrates exceeding 5,000 pounds an hour. Fair signs of larger size varieties such as side­stripe shrimp and coon-stripe shrimp were, at times, mixed with the pink shrimp.

With the exception of a 5-day storm, which occurred during the latter part ofAugust., little time was lost due to adverse weather conditions. As many of the areasfished were in semiprotected waters, small squalls did not hamper fishing activities.

INTRODUCTION

Exploratory fishing for king crab, shrimp, and bottom fish was carried out fromJuly 18 to October 1,1957, from the Shumagin Islands to Unalaska Bay, Alaska (fig.2), by the schooner-type trawler Tordenskjold. The vessel was chartered by theU. S. Bureau of Commercial Fisheries with funds provided by the Saltonstall-Ken­nedy Act of 1954.

The primary objective of this exploratory fishing was to. determine the distribu­tion and availability of king crab in waters beyond the range of those now commer­cially fished. In addition, in-formation on me distributionand availability of bottom .fishand shrimp inhabiting the areawas collected.

The presence of king crabin the inshore waters near theShumagin Islands and AlaskaPeninsula has been known formany years. Approximately4,000 male crabs were reported taken from Pavlof Bay and Canoe Bay in 1938. In1940 and 1941 fishing operations carried out in Pavlof I.ay and Canoe Bay by theAlaska Crab Investigations of the Fish and Wildlife Service revealed a crab popula­tion sufficient to support a profitable commercial operation (Anonymous 1942). Dur­ing the same investigation, Cold Bay and Volcano Bay were also reported to havefair concentrations of"king crab.

..'

The work was carried outin cooperation wit h the Bu­reau Is King Crab Investiga­tions, and during part of thecruise a biologist was aboardthe Tordenskjold to tag kingcrab and collect pertinent in­formation.

In the ensuing years the king crab fishery in this area developed slowly. Land­ings in recent years, however, have increased rapidly and between 1954 and 1956the catch from the Shumagin area rose from 316,660 pounds to 2,043,967 pounds.

Shrimp and bottom fish, with the exception of halibut and true cod, have not beencommercially exploited in the Shumagin Islands or in the areas explored along theAlaska Peninsula.

FISHING GEAR AND METHODS

Vol. 21, No. 3

Fig. 3 - The otter trawl on the surface showing the aluminumfloats.

OTTER TRAWLS; Standard 400-mesh eastern and western otter trawls were

used to carry out trawlin~ operations for king crab and bottom fish. The easterntrawl had 4t-inch mesh.!.r in the wings, square, and body, and 3t-inch mesh in theintermediate and cod end. Details of the eastern trawl have been described byGreenwood (1958). The western trawl was constructed of 4t-inch mesh throughout.

Specifications of this trawl havebeen described by Alverson (1951~From 16 to 22 aluminum-alloy 8­inch-diameter spherical floatswere spaced evenly along the headrope of each net. The last six feetof each cod end of both style trawlswere lined with 1t-inch cotton web­bing to retain shrimp and immatureking crab encountered during theexploration. All drags were madefor a period of one hour, when pos­sible, and the average towing speedwas 2.4 knots.

GULF SHRIMP TRAWL: Shrimpdrags were made with a 43-footflatGulf of Mexico-type shrimp trawl(Schaefers and Johnson 1957) con­structed from 1t- inch mesh cotton

webbing. The net, s,ecured directly to the aft end of the doors with 2-foot extensionsof the head rope and foot rope, was towed with a single warp using a 25-fathom bri­dle ahead of the doors. The shrimp trawl was usually towed for 30 minutes; how­ever, in areas where shrimp catches were large the towing time was reduced to 20minutes.

KING CRAB POTS: Cir­cular pots similar to thoseused in the commercial king­crab fishery of Alaska andpatented box-shaped collaps­ible pots were used during theinvestigation. The circularpots were 72 inches in diam­eter, and 24 inches high withtwo tunnels located oppositeeach other on the 24-inchside. The framework wasconstructed of t-inch mildsteel rod, and covered with4-inch (open mesh) webbinghandwoven from 16-gaugestainless steel wire. Ahinged access lid, approximatelythe pot.

Several variations of the standard circular pot were fished, including a 3-tun­nel pot and a number of pots with the top frame 12 inches less in diameter i:han thebottom frame.Y All mesh sizes in this report refer to stretched measure.

March 1959 COMMERCIAL FISHERIES REVIEW 11

The patented box-shape, collapsible pots were 36 by 72 inches at the base, 36by 60 inches on top, and 30 inches high. The frames were fabricated of i -inch-di­ameter galvanized mild steel rods (Schaefers et al 1955). The box-type pots provedtoo light for fishing in offshore waters and it was necessary to add approximately25 pounds of chain to the bottomof each pot to J,Jrevent drifting. I --- , \ '\\

BUOYS Ai\fDBUOY LINES:Most pot3 were fished using rub­berized canvas bags 14 to 18 inch­es in diameter as buoys. A singlebuoy served as a surface float foreach pot to hold at the surface theline from the pot on the bottomand provide a marker. Cotton belt­ing or manila rope were used asharnesses for these buoys but thelatter proved undesirable becauseof excessive chafing (see fig. 7).Cylindrical oxygen tanks of stain­less steel, painted yellow andhaving Ii· to 2 cubic feet displace­ment, were aJso used as buoys,but these were difficult to see

Fig. 5 - Weaving the webbing of stainless steel wire on a crabpot,

under certain light and water conditions.

Bu oy lines were assembled from 50-fathom lengths of to -inch orrinch-di-ameter manila rope joined to a 25-fathom length of M -inch diameter manila rope.

Sufficient sections were joined end­to-end so that the heavier lineswere always longer than the depthof water. A gill-net type, 8-inchplastic float was threaded on thelower· section of each buoy line andallowed to run free between the potand a stopper above the pot. Thismethod of rigging prevented chafingof the buoy line on the bottom or a­gainst the pot.

Marker buoys were used atboth ends of a pot string and oc­casionally at intermediate loca­tions to aid in locating the gear.These buoys were secured to an-

sisted of a taped bamboo pole 15 to 18 feet long, with a square red flag and a liferaft-type radar reflector on top. Locating gear in offshore waters proved to berelatively simple with the aid of radar reflectors (see fig. 8).

BAITlliG AND FISHING THE KING CRAB POTS: Bait bags consisted of It­inch mesh, 42-thread, treated cotton webbing, 23 meshes long and 20 meshes wide.To form the bag, square-cut webbing was folded in half and sewed along the openside and bottom. The throat was closed by threading an 18-gauge stainless steelwire through the selvage meshes so that it would operate in a slip-knot fashion.

The bag, baited with about 21 pounds of fresh or fresh frozen chopped fish wasplaced inside the pot midway between the tunnel entrances, and held in place by a

12 COMMERCIAL FISHERIES REVIEW Vol. 21, No. 3

double wire-hook arrangement. One hook was attached directly to the bait bag whilea short section of heavy rubber was used between the bait bag and the other hook.The hooks, formed from eight-gauge wire, were secured to the top and bottom ofthe bait bag and fastened to opposite tunnel entrance frames during fishing. Therubber section provided tension to hold the bait in place and allowed easy handlingof the bag.

Sculpin, arrow-toothed floun­der, and Alaska pollock were theprincipal baits, although occasion­ally other species of flat fish androundfish were tried.

The pots were usually set instrings or rows composed of 8 to20 individual pots. The totalnum­ber of pots in a string is called apot set, although for pUrpOSfil!lofcla:rity in the text and tables,some continuous strings are di­vided into two sets and other non­continuous strings are in c 1\I. d iii d

as a single and numbered accordingly.

Distances between individual pots in a string usually ranged from one-fourth toone-half mile.

As it was difficult to accommodate crabpots on deck concurrent with trawl fishing, thepots were usually hauled and reset during oneday Is operation. When feasible, trawl fishingwas conducted in the same general area on thefollowing day.

VESSEL USED: The Tord~nskjold, aschooner-type vessel, is 75 feet in length, witha beam of 18 feet, and a mean-load draft of 9feet. Built for the halibut fishery, the vesselwas converted in 1942 for use in trawl fisher­ies. This vessel was chartered by the U. S.Bureau of Commercial Fisheries earlier in1957 for bottom-fish explorations off South­eastern Alaska (Greenwood 1958).

FISHlliG RESULTS

Exploratory operations were conductedalong the south side of the Alaska Peninsulafrom Stepovak Bay westerly to Unalaska Islandin the Aleutian group. (See fig. 2.) Fishingwas carried out in most of the major bays with­in this area and in offshore waters extendingout to the 100-fathom contour. During the ex­ploration, 61 otter-trawl drags were made for

Although the catch per pot as averaged for an aggregate station catch was, inmany instances, below the level needed to sustain a commercial operation, occasion­ally individual pot catches were excellent.

STEPOVAK BAY TO PAVLOF BAY: Explorations in this area included mostof the major bays along the Alaska peninsula between Stepovak Bay and Pavlof Bay,and the offshore waters to depths of 100 fathoms. A total of 27 otter-trawl drags,18 crab pot sets, and 28 Gulf-shrimp-trawl drags was made in this area. The baysand inlets trawled were generally free of snags although hang-ups were noted out­side of Beaver Bay, in Unga Strait, near Sealion Rocks, and in the offshore waters

douth of the Shumagin Islands.Bottom samples indicated thesea bed through much of thearea was composed of greenmud, occasionally mixed withsand. Off Pavlof Bay, lava andshell were found, mixed withgreen mud.

~ing-Crab Catches--OtterTraw: King-crab catches madeWITIl1heotter trawl were smallthroughout the area. The bestcatch, made 22 miles south of

Sealion ~ocks, yielded 10 kingcrabs ,~/ considerably below theminimum necessary to sustaina commercial operation.

Fig. 10 - FiWDg • bait bag with chopped flah. K' C b C tch P t~- ra a es-- 0 s:The best crab-pot catches were made in Stepovak Bay, oTfl:1iichagof Bay, and--rn-­

Dorenoi Bay and vicinity. Fifty-one crab pots fished in these localities (pot-setnumbers 28, 29, and 30) at depths rangipg from 17 to 104 fathoms for an average of92.6 hours yielded a total of 660 king crabs. The only other pot set (number 16)which produced likely results was made 9 miles southwest of Unga Island in 70 to 87fathoms. This set consisting of 10 pots caught 79 king crabs, with 66 of them oc­curring in 4 of the 10 pots.

Shrimp Catches--Otter Trawl: The small-mesh liner used in the otter trawlproved an effective means of ascertaining the presence of significant quantities ofshrimp, and initial drags made in Unga Strait and Balboa Bay yielded good catches.

One otter-trawl drag (number 3) made in Balboa Bay produced 760 pounds of

shrimp in one hour. The catch was composed predominately of pink shrimp whichaveraged 122~/ to the pound. The area south of Sealion Rocks also yielded goodcatches with three 1-hour otter-trawl drags (number 4, 6, and 7) resulting in catch­es ranging from 240 to 900 pounds of shrimp. The catches consisted chiefly of pinkshrimp averaging approximately 113 to the pound, although drag number 4 produced100 pounds of side-stripe shrimp averaging 28 to the p'ound.

Shrimp Catches--Gulf Trawl: To better evaluate the shrimp potential, areaswhich gave promising results with the lined otter trawl were subsequently fishedusing the 43-foot Gulf trawl. Additional shrimp trawl drags were made in otherareas where the bottom topography and depth indicated possible shrimp concentra­tions.YUnleas otherwise noted, only legal-size king crab (hard-Ihell males not less thlUl ot inches in greatest width of shell)

are referred to in the text.AlAII shrimp counts given are the number of whole (heads on) shrimp per pound. Complete details of number of whole

Fig. 13 - A good catch of shrimp made lOuth of Sealion Roc1<ausing the43-foot Gulf of Mexico-type shrimp trawl.

Good catches of shrimp were made with the Gulf trawl south of Sealion Rocks.Two shrimp drags (numbers 2 and 5) produced catches at a rate exceeding 4,000pounds an hour and several shrimp drags (numbers 1, 3, and 4) caught shrimp atrates in excess of 2,000 pounds an hour. These catches consisted of mixed pink,side-stripe, and coon-stripe shrimp; however, pink shrimp was the predominantspecies. The best catch of side-stripe shrimp was made in a shrimp drag (number5), which yielded 400 pounds in 20 minutes. The pink shrimp caught in the SealionRock area ranged from 118 to 157 to the pound, while side -stripe shrimp caught indrag number 5 averaged 57 to the pound.

Inshore explorations for shrimp were carried out in Balboa Bay, Unga Strait,and Stepovak Bay and outside of Beaver and Pavlof Bays. All of these localitiesproduced excellent shrimp catch-es. Balboa Bay and Unga Straitboth yielded catches which ex-ceeded a rate of 4,000 pounds anhour, while the grounds off Pav-lof Bay produced shrimp at ratesup to 7,300 pounds an hour. Thegrounds adjacent to Pavlof Baygave the most consistent largecatches of shrimp. Four dragsin this area produced catches atrates exceeding 5,000 pounds anhour and 3 drags produced catch-es at a rate in excess of 3,000pounds an hour. The best indi-vidual catch made during thecruise was made outside BeaverBay when 3,800 pounds of shrimpwere taken in a 30-minute drag(number 29).

Pink shrimp dominated thecatch in the inshore bay area;however, catches of side-stripeshrimp in excess of 100 poundsper 20-minute drag were com­mon. Sample counts for pinkshrimp in these areas rangedfrom 92 to 227 per pound, whileside-stripe counts ranged from26 to 135 per pound.

COLD BAY TO SANAK IS­LAND: Explorations in this­area included Cold Bay, the wa­ters between Unga and Sanak Islands, and the adjacent waters to the east of SanakIsland. Eight otter-trawl drags were made at depths of 40 to 83 fathoms, and fourcrab-pot sets were made at depths between 38 and 82 fathoms in this area.

K~ng Crab Catches--Otter Trawl: The best-otter-trawl catch of king crabs wasmade etween Unga Island and Cherni Island (drag number 39). This drag, made atdepths from 66 to 74 fathoms, resulted in a catch of 42 crabs. Other otter-trawlcatches resulted in only minor catches of crab.

King Crab C~tches--Pots: The largest individual catch was made (set number21) betwe~erni and Unga Islands. A set of 20 pots at depths from 58 to 78 fath-

oms caught 333 king crabs. The next largest catch, 164 was made with 16 pots fish­ed for 26 hours in Cold Bay (set number 31).

Shrimp Catches: Insignificant catches of shrimp were noted in the lined ottertrawl drags made in this area, and no attempts were made to locate shrimp with theGulf shrimp trawl.

MORZHOVOI BAY TO DAVIDSON BANK: Exploratory fishing in this region wasconducted in Morzhovoi Bay and Ikatan Bay and on Davidson Bank, south of Unimak Is­land. A total of 21 otter-trawl drags and 7 sets of king crab pots was made in the area.The drags made in Morzhovoi Bay and Ikatan Bay were free of snags and most of Davidson

Bank was found suitable for trawling. A consid­erable amount of gravel bottom was noted onDavidson Bank, while green mud was commonin bottom samples taken from the bay areas.

Crab and Shrimp Catches: Both otter­trawr0:r8.gs and pot sets resulted in insignifi­cant king crab catches. Shrimp catches in thelined otter-trawl were also unfavorable.

AKUTAN BAY TO UNALASKA BAY: Ex­plorations in this area were made in AkutanBay, Beaver Inlet, and Unalaska Bay. Fourotter-trawl drags, 5 pot sets, and 7 drags withthe Gulf shrimp trawl were made. No snagswere encountered during trawl operations;however, the bottom topography was irregularand only a limited amount of trawling groundwas located.

Crab and Shrimp Catches: Crab catchesmade with tne otter-trawl were poor. Althoughthe average catch of crabs per pot in this areawas low, a few pots fished in Akutan Bay andUnalaska Bay yielded fair catches. In AkutanBay, 2 pots caught 31 crabs, and in UnalaskaBay I 4 pots caught 86 crabs. Only 1 drag pro-duced any quantity of shrimp. One drag (num­ber 35) made in Beaver Inlet with the Gulftrawl resulted in a catch of 175 pounds of mix­ed pink ana side-stripe shrimp.

INCIDENTAL FISH AND SHELLFISH CATCHES: The best catch of food fishmade during the explorations was taken 7 miles southeast of Cape Lazaref in 59 to62 fathoms where 5,000 pounds of true cod were caught with the otter-trawl (dragnumber 41). Other catches of food fish were generally small. Species of fish cap­tured in small amounts included rock sole, pollock, sculpin, and turbot.

Tanner crabs were distributed throughout most of the region explored. In Un­alaska Bay, 13 pots produced a catch of 1,109 tanner crabs with 169 crabs taken in1 pot. A catch containing 555 tanner crabs was also taken in lotter-trawl drag madein Ikatan Bay.

Dungeness crabs were taken only in sets made in close proximity to the beachand in comparatively shallow water, such as Unimak Bight and Acheredin Bay. Catch­es of Dungeness ~rabs were small even in these areas.

With the exception of a five-day storm during the latter p~t of August, littletime was lost because of adverse weather conditions. The weather was generallyovercast and cloudy with intermittent rain and fpg. As many of the areas exploredwere in semi-protected waters, small squalls did not interfere with fishing activi­ties.
