Coho salmon, also known as silver salmon, are native to cold-water rivers in North America from California to Alaska, Northern Japan, and eastern Russia. Coho salmon are born in freshwater streams where they spend 1 to 2 years rearing often in off-channel sloughs and brackish waters. Juvenile Coho Salmon migrate to the Pacific Ocean between March and July and remain in salt water for 1 to 3 years. Adult Coho Salmon, weighing between 7 and 11 pounds, return to their natal rivers in during fall months where they spawn. All Coho salmon die after spawning.
