Coho salmon, also known as silver salmon, are a species of fish found in the North Pacific Ocean. They are recognized for their bright silver sides and distinctive dark spots on their backs. Coho salmon typically weigh between 8 to 12 pounds and can grow up to 30 inches long. They are anadromous, meaning they are born in freshwater, migrate to the ocean, and return to freshwater to spawn. These fish are an important part of the ecosystem and are popular among anglers due to their fighting ability and delicious taste. Coho salmon are often harvested for commercial and recreational fishing, contributing to local economies. Their life cycle includes several stages, from eggs to fry, and eventually to adult fish that return to their natal streams to reproduce.
