Alaska Pollock [Theragra chalcogramma]
Description
The Alaska pollock or walleye pollock is a marine fish species of the cod family Gadidae. It is a semipelagic schooling fish widely distributed in the North Pacific with largest concentrations found in the eastern Bering Sea. While belonging to the same family as the Atlantic pollock, the Alaska pollock is not a member of the same Pollachius genus. Alaska pollock has well-developed drumming muscles that the fish use to produce sounds during courtship, a characteristic that is unique among the Gadidae. The species has been the target of commercial fisheries since the 1960s and is considered the second most important fish species in the world in terms of total catch.
