YANG and LIVINGSTON: F-OOn HABITS OF GREENLAND HALIBIT 



Table 1.— Prey items found in the stomachs of Greenland halibut collected in the eastern Bering Sea during summer 1983 through fall 

 1985. %F0 = percent frequency of occurrence, %/V = percent by number, %W = percent by weight, t = <0.01% W. 



nant prey in the diet due to the consumption of 

 walleye pollock by Greenland halibut >70 cm; how- 

 ever, cephalopods and other fishes were more im- 

 portant than gadids for the two smaller size groups. 



Depth 4 (^600 m) 



No stomachs were collected for fish smaller than 

 30 cm in this depth group (Fig. 2D). For size groups 



30-49 cm, cephalopods were the dominant prey 

 (56%) of Greenland halibut in terms of percent by 

 weight, followed by bathylagids at 29%. However, 

 the percent of number and the percent of frequency 

 of occurrence of bathylagids (FOG in Figure 2D, up- 

 per left) were higher than those of the cephalopods. 

 The stomach contents (by weight) of Greenland 

 halibut 50-69 cm long was composed of 57% 

 cephalopods, 22% macrourids, 12% bathylagids, 4%
