Coho, also known as silver salmon, is a species of fish found in the North Pacific Ocean. They are popular among anglers due to their fighting ability and are often sought after for their rich, flavorful meat. Coho salmon typically have a bright silver body with small black spots on their back and upper fins. These fish are anadromous, meaning they are born in freshwater rivers, migrate to the ocean, and return to freshwater to spawn. Coho salmon play a vital role in their ecosystems, providing nutrients to both aquatic and terrestrial environments when they die after spawning.
