Sockeye Salmon

Also known as the redfish, red, or blue-black, they are the most important commercial species. Sockeye have long gill rakers as they primary feed on plankton when in the ocean. They have the greatest life history diversity and can spend anywhere from 3 months to 3 years in freshwater. They will spawn near shorelines, the bottom of lakes, or hundreds of miles upstream. Fry of this species rears almost exclusively in lakes. While in the ocean they are greenish blue on top of the head and back, silvery on the sides, and white to silver on the belly. During the spawning phase the head and caudal fin become bright green and the body turns scarlet. Land locked populations of this species are known as kokanee. These fish generally live 2-6 years, are about 21-26in in length, and weigh about 4-7lbs.
