Yield and biomass status for groundfish


2015 Stock Assessments for 2016 Fishery Recommendations

Stock Assessment result summaries and archive

Completed 2016 Pacific cod CIE reviews
 

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.

 In late 2000 the Resource Ecology and Fisheries Management (REFM) division formed the Fishery Interaction Team (FIT).  The primary responsibility of the team is to investigate interactions between fisheries and endangered Steller sea lions (SSL).
