600,000 spring Chinook salmon

Kooskia National Fish Hatchery in Idaho raises and releases 600,000 spring Chinook salmon annually into the Clearwater River Basin.

Since 2007, the hatchery has been managed by the Nez Perce Tribe after the certification of the Snake River Basin Adjudication settlement. Adult spring Chinook salmon are trapped in Clear Creek at Kooskia National Fish Hatchery from May through August and then transported to Dworshak National Fish Hatchery in Idaho for spawning.

"Eyed" eggs are returned to Kooskia in the fall, where they are incubated, hatched, and reared. They are released 18 months later as smolts (juvenile salmon) into Clear Creek. http://ow.ly/9PgY50Me3p5
