Understanding Silver Salmon (Coho): Size, Characteristics, and Habitat

Silver salmon, also known as coho, typically average 10 lbs, with a record of 26 lbs. Known for their aggressive nature, they adapt well to land-locked lakes and are hardy fish. Their life cycle includes 1-2 years in freshwater and up to 3 years, followed by 1.5 years in the ocean. Distinctively, they have no black spots on their dorsal fin and develop a reddish hue when approaching spawning areas. Silver salmon are prevalent in Alaska, with 75% of all catches sourced from the region, and are introduced into the Great Lakes.
