Chinook salmon, also known as king salmon, is the largest species of Pacific salmon. They are known for their rich, high-fat content, which makes them a popular choice for cooking and fishing. Chinook salmon can weigh up to 130 pounds and are typically found in the North Pacific Ocean, migrating to rivers and streams to spawn. These fish have a distinctive coloration, with a blue-green back and silver sides, often featuring black spots. Chinook salmon are anadromous, meaning they are born in freshwater, migrate to the ocean, and return to freshwater to reproduce. Their life cycle plays a crucial role in the ecosystem.
