Cutthroat trout Oncorhynchus clarki. Taxon: Freshwater fish Range: Cutthroat trout are native to the Western United States; introduced in the Southeast. Status: Not listed under the Endangered Species Act, but several subspecies are considered threatened in their native ranges. Cutthroat trout are freshwater fish in the family Salmonidae, as are rainbow trout. Cutthroat tells the full story of the genuine native trout of the American West. This new edition, thoroughly revised and updated after 20 years, synthesizes what is currently known about one of our most interesting and colorful fishes, includes much new information on its biology and ecology, asks how it has fared in the last century, and looks toward its future. The cutthroat trout (Oncorhynchus clarkii) is a fish species of the family Salmonidae native to cold-water tributaries of the Pacific Ocean, Rocky Mountains, and Great Basin in North America, and is the state fish of Wyoming.
