Freshwater streams and estuaries provide important habitat for many salmon species. They feed on terrestrial and aquatic insects, amphipods, and other crustaceans while young, and primarily on other fish when older. Eggs are laid in deeper water with larger gravel, and need cool water and good water flow (to supply oxygen) to the developing embryos.

The young hatch and grow in freshwater rivers, streams, and creeks for several years. As they reach adulthood they move into the ocean. They only return to freshwater habitats when they reproduce.
