Primary water types where this species is found.
Channel catfish are an introduced species in Idaho and are established in warm, larger river reaches and reservoirs. They are popular with anglers because they bite readily, fight hard, and can grow very large.
They feed mostly on small fish and bottom forage like crayfish, clams, snails, and aquatic insects.
