Tuna Species of the U.S. West Coast: A Photographic Identification Guide

Species-specific life history parameters are used in population stock assessments conducted by SWFSC researchers to allow managers to determine sustainable harvest rates, respond to natural and introduced changes in populations, and predict the impacts of various management scenarios. SWFSC scientists work with scientists from other nations within tuna Regional Fisheries Management Organizations to conduct and review assessments on highly migratory fish stocks. Assessment results and management advice on pelagic species in the EPO are provided to the Pacific Fishery Management Council of the United States.
