Environmental variability and spatial differentiation pollock in the Bering Sea
Abstract
Environmental variability in Subarctic and in the Bering Sea affects on recruitment, abundance, behavior and seasonal spatial distribution of pollock and plankton community which challenge on fishery management strategy. Understanding of environmental driven changes in pollock population can be used to improve predictions of assessed population and will positively affect on recreational fishing, commercial harvest and fishery-dependent coastal communities. Especially this knowledge explores the impacts of environmental projections to applied fishery problems in the northwestern Bering Sea, Russian waters, where eastern Bering Sea pollock (Theragra chalcogramma) migrates just in summer and autumn periods, for development of environmental-enhanced strategy of fishery management. The great annual differences of pollock seasonal migration and spatial distribution are related with variability of it population abundance, temperature condition and zooplankton species composition, abundance and distribution in the Bering Sea.
