COHO ECOLOGY &
REGULATORY OVERVIEW
Along the Pacific Coast, populations of coho salmon have significantly declined over the last century. Coho salmon in California are currently estimated to be no more than 15 percent of their 1940s abundance. Private landowners, organizations such as resource conservation districts, and government agencies have responded to this decline by conserving and restoring critical habitat within the Russian River Watershed and throughout California. The stewardship of habitat, by these groups and others, has created the opportunity to take the next step in recovering coho.
Since 2001, a collaborative effort has been underway to re-establish coho in the Russian River. Partners carefully capture, rear, and spawn coho broodstock. They then release the off-spring as young fish in select tributary streams and monitor their growth and survival until the time arrives for them to move downstream and into the Pacific Ocean. This cycle will be repeated annually, along with the monitoring of adult coho returning three years after their release to tributary streams.
