					Feeds on fishes and planktonic crustaceans (Ref. 1394). Incidental injuries and death of this species are caused by commercial fishing gears, i.e., flatfish trawl, pollock trawl, cod trawl, and cod longline (Ref. 118427). Typically stays in ice-covered waters year-round (Ref. 117965).  Feeds on fishes (Ref. 1394) and planktonic crustaceans like pelagic amphipods and mysids (Ref. 117965).
