Some Aspects of the Walleye Pollock (Theragra chalcogramma) Biology and Fishery Related to the Size and Age Structure in the Southwestern Chukchi Sea

Summary: This study examines the impact of climate change on Arctic gadids, focusing on species distribution shifts in warm and cold periods. It found that sub-Arctic species are more affected by environmental changes, while Arctic species are more constrained to specific geographic areas. Species with a demersal life history showed better tolerance to thermal conditions. These insights are crucial for understanding the responses of fish to changing ocean conditions in polar regions.
