Oceanographic conditions and analysis of walleye pollock Theragra chalcogramma fishery in the Navarin area in 2017–2021
The northwestern Bering Sea, in particular the waters at Cape Navarin, is one of the main areas of the walleye pollock fishery. Environmental variability in the Bering Sea affects on recruitment, abundance, behavior, and seasonal spatial distribution of pollock, which challenge on the fishery manage...
