Stock Assessment

Stock Assessments

Scientists at the SWFSC assess the status of marine and anadromous fish and protected species populations. They use biological data collected in field surveys as well as catch and other data collected from the fisheries. Our assessments provide the fundamental information for determining the status of a population and for managing the populations domestically and internationally. Links to the assessments and information about assessment methods and species groups are listed below.



Sardine, squid, anchovy and mackerel – Coastal Pelagic Species


Tunas, sharks and billfish – Highly Migratory Species
