Rainbow trout, primarily hatchery-raised fish of the coastal rainbow trout subspecies (O. m. irideus) introduced into waters inhabited with cutthroat trout, will breed with cutthroats and produce fertile hybrids called cutbows. Rainbow trout introductions have caused a severe reduction in the range of the native cutthroat trout through hybridization and competition.
