About the Species

Chum salmon. Credit: NOAA Fisheries

Chum salmon may historically have been the most abundant of all Pacific salmonids. They are an anadromous fish, which means they can live in both fresh and saltwater. Chum salmon 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. They are vulnerable to many stressors and threats including blocked access to spawning grounds and habitat degradation caused by dams and culverts. Two evolutionary significant units of chum salmon are listed as threatened under the Endangered Species Act.

NOAA Fisheries is committed to conserving and protecting chum salmon. Our scientists and partners use a variety of innovative techniques to study, learn more about, and protect this species.
