and Washington; it represented 73.8, 100.0, 

 and 47.7 percent, respectively, of the total 

 volume of food (appendix fig. 1). 



Walleye pollock fornned 14.0 percent of 

 the total volume and ranked third as a food 

 species in the Bering Sea (appendix fig. 6). 

 It was one of the main foods of fur seals in 

 the Bering Sea in 1962 and 1963 (Fiscus, 

 Baines, and Wilke, 1964; Fiscus, Baines, and 

 Kajimura, 1965). 



Sebastodes spp. The remains of two rock- 

 fish were found in the stomach of a fur seal 

 collected off Washington (appendix fig. 2). 



Anaplopoma fimbria . Found in 13 fur 

 seal stomachs (10 from the Eureka grounds) 

 collected off California (appendix fig. 4); 

 ranked third in innportance as a food and 

 formed 7.5 percent of the total volume of 

 food. 



Pleurogrammus monopterygius . Identi- 

 fied in stomachs of four fur seals from the 

 Bering Sea (appendix fig. 8). 



Cyclopteridae. Aptocyclus ventricosus 

 occurred in stomachs of two seals from the 

 Bering Sea (unidentifiable remains of a cy- 

 clopterid in a third stomach). One seal con- 

 taining this species was from a shallow-water 

 area northwest of St. Paul Island, in sector 4, 

 zone 3; the other was from a deepwater area 

 in sector 3, zone 3 (appendix fig. 8). 



Ammodytes hexapterus . Six occurrences 

 in fur seal stomachs in 1964 (appendix fig. 7), 

 The species was also of minor importance 

 as a food of fur seals in 1962 and 1963. 



Anarhichadidae. The stomachs of five 

 seals from the Bering Sea in shallow- water 

 areas of sector 3, zone 3 and sector 5, zone 3 

 contained anarhichadids (appendix fig. 5). 

 A specimen of Ana r hie has orientalis from 



T"^ 



one of the stonnachs was 12.5 cm. long 

 from tip of snout to end of hypural plate. ^5 

 This is the first record of Anarhichas in fur 

 seal stomachs since L,ucas (1899) identified 

 two specin-iens of A. lepturus . ( A. lepturus is 

 a synomym for A_, orientalis - -Jordan and 

 Evermann, 1896.) 



Pleuronectidae. Pleuronectidae were in 

 the stomachs of 35 fur seals from Bering Sea. 

 Fragments in two stomachs could be identified 

 only to family, but remains in 33 stomachs 

 were Greenland halibut ( Reinhardtius hippo- 

 glossoides ) (appendix fig. 8). 



Greenland halibut occurred in the shallow- 

 water areas of sectors 3, 4, 5, and 6, zones 

 1, 2, 3, and 4, in Bering Sea; it represented

 of Fisheries, University of Washington, Seattle, Wash. 



2.1 percent of the total volume of food and 

 ranked seventh in importance. It also was an 

 important food item in 1963; it is the principal 

 pleuronectid eaten by fur seals in the Bering 

 Sea. 



Greenland halibut is normally found in the 

 North Atlantic but has been reported in the 

 North Pacific and the Bering Sea in recent 

 years. Hubbs and Wilimovsky (1964) studied 

 the distribution, and variations in morpho- 

 logical and meristic characters, of the North 

 Pacific and North Atlantic species. Best (1963) 

 reported the species from the coast of Cali- 

 fornia in 1962. Fiscus, Baines, and Kajimura 

 (1965) recorded 16 occurrences in fur seal 

 stomachs from the eastern Bering Sea in 

 1963. 



Most fragnnents of Greenland halibut in 

 fur seal stomachs to date have been from 

 imnnature fish, but the size was generally 

 larger in 1964 than in 1963. The 1963 speci- 

 mens ranged from 4.5 to 6.0 cm. (tip of snout 

 to end of hypural plate); in 1964, the length 

 of the vertebral column of one specimen was 



11.2 cm., and the length of the caudal vete- 

 brae in seven others ranged from 6.3 to 

 8.8 cm. 



Squids 



Squids were the major food in fur seal 

 stomachs from the Bering Sea in 1964, ranked 

 second in California, were unimportant in 

 Oregon, and ranked fifth in Washington. For 

 the four areas combined, squids formed 28.2 

 percent of the total volume of food. The follow- 

 ing five species of squids were identified: 

 Loligo opalescens , Onychoteuthis banksii , 

 Gonatus fabricii, Gonatus magister , and 

 Gonatopsis borealis (appendix fig. 2, 3, 4, 

 6, 7, and 8). 



Loligo opalescens ranked second as a 

 food off California. It was in stomachs of 74 

 seals from the Eureka and Farallon grounds 

 and made up 12.9 percent of the food volume; 

 it was a minor food of fur seals off Oregon 

 and Washington. The mean dorsal mantle 

 length (DML) of 35 undigested specimens from 

 one stomach was 12.6 cm. (range, 11.0 - 14.6 

 cm). 



Onychoteuthis banksii occurred in 27 

 stomachs from the Eureka and Farallon 

 grounds and in trace amounts in 5 stomachs 

 from Oregon. Off California it represented 

 2.4 percent of the total volume of food. One 

 specimen measured 22.0 cm. DML. 



Gonatus fabricii and G. magister , and 

 Gonatopsis borealis occurred in minor announts 

 off California, Oregon, and Washington. 

 G^. fabricii was in 65 fur seal stomachs fronn 

 deep water in sectors 1, 2, and 3 of the Bering 

 Sea. G. magister ranked second in importance 

 as a food in stomachs from the Bering Sea, 

 forming 27.9 percent of the total volume and 



78.3 percent of the volume of squids; two of
