The Bonneville cutthroat trout is Utah’s state fish. This species is actually native to the Great Salt Lake, which is found in Utah. However, they aren’t found only in Utah. This fish can also be found in Idaho, Nevada, and Wyoming - or at least in parts of all three of these states’ waterways. This is what Utah residents decided to use to replace the rainbow trout as their state fish.
It has been used as a source of food since the Mormon pioneers trekked out to the Utah plains in the early 1850s. Though at one time considered a nuisance, today they are on the endangered species list for Utah because of how easy they are to catch and how often they were caught in big batches up through to the 1920s.
