The Chinook Salmon is anadromous– born in freshwater, migrating to the ocean, and returning as mature adults to their natal streams to spawn. Freshwater streams, estuaries, and the open ocean are all important habitats. The freshwater streams are relatively deep with course gravel. The water must be cool, under 14 C for maximum survival, and fast flowing. Estuaries provide a transition zone between the freshwater and saltwater and the more vegetation the better because there will be more feeding and hiding opportunities. At sea, Chinook Salmon can either stay close to shore or migrate thousands of miles to deep in the Pacific.
