Bonneville cutthroat trout

The Bonneville cutthroat trout, Oncorhynchus virginalis utah, (formerly, O. clarkii utah) is a subspecies of Rocky Mountain Cutthroat Trout native to tributaries of the Great Salt Lake and Sevier Lake. Most of the fish's current and historic range is in Utah, but they are also found in Idaho, Wyoming, and Nevada. This is one of 14 or so recognized subspecies of cutthroat trout native to the western United States. However, In 2023 the American Fisheries Society Common and Scientific Names of Fishes from the United States, Canada, and Mexico, 8^th edition reclassified all Cutthroat Trout from one species (formerly, Oncorhynchus clarkii) into four distinct species: Coastal, Lahontan, Westslope, and Rocky Mountain Cutthroat Trout. The Bonneville Cutthroat retained their trinomial designation as a subspecies (utah), but as a subspecies of the Rocky Mountain Cutthroat Trout (Oncorhynchus virginalis).

In 1997, the Bonneville cutthroat was designated the official state fish of Utah, replacing the rainbow trout. It was important to the Native Americans and the Mormon pioneers as a source of food.
