Status of Stocks and  Multispecies Assessments

Yield and biomass status for groundfish

Stock Assessment result summaries and archive 

Members of the Alaska Fisheries Science Center's (AFSC) Stock Assessment and Multispecies Assessments Program are responsible for determining the condition of fisheries resources in the U.S. Exclusive Economic Zone using data collected by other AFSC scientists and developing strategies for managing those resources. Their research focuses on updating information on population dynamic trends, estimation of biological yields, and management strategies (as presented in annual assessments).  Members of our staff have contributed to the development of the National Standard Guidelines.
