Scientific name: Gadus chalcogrammus · Water: Saltwater, Brackish
Size: up to 91 cm
The Alaska pollock is a benthopelagic gadid recorded from the surface down to 1,280 m; adults usually live near the sea floor but sometimes appear near the surface, and they perform diurnal vertical migrations. It is one of the straddling stocks of the north-west and north-east Pacific. It feeds mainly on krill but also eats fishes and crustaceans, and spawning adults were often caught solely for their roe, a practice effectively banned in the Bering Sea and Gulf of Alaska by a 1994 amendment to the fishery management plans. Its range runs from Norway to Svalbard and east to the Laptev Sea, South Korea and the Beaufort Sea, and south to California. Maximum length is about 91 cm total length, and it can live 28 years, maturing at about 37 cm. It is a highly commercial species and a gamefish, with a low price category. Fishing vulnerability is high at 59 of 100 and resilience low, and climate vulnerability is high at 55 of 100.
