Salmon Population Summaries (SPS)
June 30, 2020
This site was designed to provide access to demographic data compiled for ESA-listed salmonid populations as part of the NWFSC's technical recovery planning efforts.
The database contains data on spawning abundance, age structure of wild spawners, fraction of natural spawners that are of wild origin, and the reduction in spawning abundance due to harvest. For some populations, additional data fields are also available. The data correspond to the populations identified by the NOAA Fisheries Technical Recovery Teams, and are used in part to assess population and ESU-level recovery criteria for many listed ESUs.
