Special needs

Require streams with clean gravel, complex habitat, and cool temperatures for spawning and rearing. Require access for anadromous migration. Productive nearshore marine habitat that provides high-quality prey in sufficient quantity for rapid growth at time of ocean entry.

Limiting factors

Stream complexity. Water quality. Fish passage. Riparian condition. Alterations of hydrology and watershed function. Marine survival.

Conservation actions

Maintain or restore aquatic and riparian habitat. Continue ongoing restoration efforts involving landowners, tribes, and agency partners (NOAA, NMFS, ODFW, OWEB). Manage for sustainable harvest.
