Data are currently limited or lacking for several federally managed rockfish species of the genus Sebastes found within the Gulf of Alaska. This project is related to the core mission of the Alaska Fisheries Science Center as it will provide data which will refine and improve assessment models for these commercially important species. The initial data collection from this project began in 2009 and is on-going. Samples of a variety of rockfish species have been collected from several years and in several locations throughout the Gulf of Alaska. These data are stored in database files (MS Excel or MS Access).
