While in freshwater, Chinook Salmon fry and smolts feed on plankton and then terrestrial and aquatic insects, amphipods and crustaceans. After migrating to the ocean, the maturing adults feed on large zooplakton, herring, pilchard, sandlance and other fishes, squid, and crustaceans. Once the adult salmon have re-entered freshwater, they do not feed. In the Great Lakes, Chinook Salmon were introduced to control the invasive alewife population (National Wildlife Federation, 2002; Delaney and ADFG, 1994; Government of Canada, 2002).
