 Habitat, biology, and fisheries: Inhabits continental shelf depths from about 55 to 300 m, but also found in upper-slope waters to more than 900 m; occasionally strays into shallow coastal waters; seasonally migrates to shallower waters during warmer months, to deeper offshore waters in winter.Young of 1 to 3 years feed primarily on invertebrates (mostly crustaceans, especially euphausiids and pandalids); older fish feed mostly on fish and cephalopods; cannibalism significant and may regulate population of species. Spawning occurs in summer and early autumn and is highly dependent on water temperature. An important commercial fish in Area 21, but not found in significant quantities in Area 31. Marketed fresh, frozen, and smoked.
