Including the five species of Northwest salmon, steelhead, and certain bull trout, anadromous fish refers to those that migrate from freshwater rivers to the ocean and back to spawn in their natal streams. These populations of fish play an integral role in the wildlife community. Bears, otters, eagles, and many others feast on salmon carcasses as a main source of protein when other food is scarce. As well as a significant food source for members of the park community, the life cycle of various anadromous salmon stocks facilitates the transportation of key nutrients to lakes, rivers and streams.
