508 Alaska pollock Theragra chalcogramma Alaska pollock or walleye pollock (Theragra chalcogramma) is a species of the cod family Gadidae. Alaska pollock is a semipelagic schooling fish widely distributed in the North Pacific with largest concentrations found in the eastern Bering Sea. While related to the common Atlantic pollock species of the same family, the Alaska pollock is not a member of the same Pollachius genus. Rather, recent research suggests that it is more closely related to Atlantic cod, and that Alaska pollock should be moved back to genus Gadus in which it was originally described as Gadus chalcogrammus. Furthermore, Norwegian pollock (Theragra finnmarchica), a rare fish of Norwegian waters, is likely the same species as the Alaska pollock. 164722 Alaska pollock 508.jpg image/jpeg 62703 2012-04-20T09:32:02Z 535 Aquatic foods Fishes Type 1 2011-02-09T00:37:45Z 2019-05-14T18:05:26Z false specific 1042646 true FOOD00497
