Sockeye Salmon - Protected
About the Species
Sockeye salmon are anadromous fish, which means they can live in both fresh and saltwater. They have a relatively complex life history that includes spawning and juvenile rearing in rivers followed by migrating to saltwater to feed, grow, and mature before returning to freshwater to spawn. Sockeye salmon are vulnerable to many stressors and threats including blocked access to spawning grounds and habitat degradation caused by dams and culverts. One evolutionary significant unit is listed as endangered and one ESU is listed as threatened under the Endangered Species Act.
NOAA Fisheries is committed to conserving and protecting sockeye salmon. Our scientists and partners use a variety of innovative techniques to study, learn more about, and protect this species.
- Snake River ESU
- Ozette Lake ESU
One evolutionary significant unit of sockeye salmon is listed as endangered and one ESU is listed as threatened under the Endangered Species Act.
The threatened and endangered ESUs of sockeye salmon were listed under the ESA on June 28, 2005. We had previously listed the Snake River ESU and Ozette Lake ESU in 1991 and 1999, but we reaffirmed the listings in 2005.
We designated critical habitat for the Snake River ESU on December 28, 1993 and for the Ozette Lake ESU on September 2, 2005.
NOAA Fisheries conducts various research activities on the biology, behavior, and ecology of sockeye salmon. The results of this research are used to inform management decisions for this species.

Sockeye Salmon in Alaska
Our work to forecast salmon harvests, assess the impact of commercial fisheries on salmon, and evaluate how salmon populations respond to environmental changes enable us to estimate abundance and trends for sockeye salmon in Alaska.
