Results of the 1990 U.S.-U.S.S.R. cooperative bottom trawl survey of the eastern and northwestern Bering Sea continental shelf
Abstract
The Alaska Fisheries Science Center (AFSC) of the United States and the Pacific Research Institute of Fisheries and Oceanography (TINRO) of the Union of Soviet Socialist Republics (U.S.S.R.) conducted a cooperative bottom trawl survey of the Bering Sea aboard the Russian research vessel Novokotovsk during May-July 1990. The primary purpose of this survey was to assess the distribution, abundance, and biological condition of groundfish resources in both the eastern and western Bering Sea continental shelf. A separate and completely independent trawl survey of the central and southeastern Bering Sea continental shelf was also conducted by the AFSC during this period aboard two U.S. research vessels.
Results summarizing geographic distribution, abundance estimates, and size composition are presented for the principal species of fish encountered. The distribution and relative abundance of the commercially important crab species are also shown. Results of the cooperative survey are compared to the results of the separate 1990 U.S. survey from the areas commonly fished in the eastern Bering Sea. The appendices include station and catch information, detailed abundance, size, and age data.
