Regional, interannual and size‐related variation of age 0 year walleye pollock whole body energy content around the Pribilof Islands, Bering Sea
Mean whole energy content ( E wb ) of age 0 year walleye pollock Theragra chalcogramma was 19.928 KJ g −1 dry mass in 3943 fish collected from different habitats around the Pribilof Islands frontal structure, south‐east Bering Sea, during September 1994–1996 and 1999. It varied, however, with habita...
