  • Description:
    The 1983 data report is one in a series describing results of annual eastern Bering Sea resource assessment surveys. The report is divided into three sections: survey methods, results, and appendices. The methods section describes survey procedures, vessels and gear, the data collected, and procedures for its analysis. The results section presents a list of fish species taken during the survey and abundance estimates for fish and invertebrate families. Also included are rank orders of abundance of individual fish species, and geographic distributions, size and age compositions, and abundance estimates of principal groundfish species. The appendices contain computer listings of station and catch data, rank order of abundance for fish and invertebrates, population and biomass estimates by survey strata, population estimates by sex, age, and size groups, and age-length keys.
