SWFSC scientists in the Fisheries Ecology Division conduct biological and economic research of salmonid fishes in California that are listed as threatened or endangered under the Endangered Species Act. Research supporting their restoration and recovery includes: distribution and abundance, metapopulation dynamics and viability analysis, population genetics, life history tactics and strategies, spatial ecology, wild/hatchery interactions, and ocean and estuarine ecology.  Information on the individual salmon species can be obtained on the NOAA Fisheries Office of Protected Resources Marine and Andadromous Fishes webpage.
