Fish of Yellowstone National Park



There are twelve (12) native species in Yellowstone National Park (including three [3] species of cutthroat trout). The native species are: Arctic Grayling, Longnose Dace, Longnose Sucker, Mottled Sculpin, Mountain Sucker, Mountain Whitefish, Snake River Cutthroat (not a formally recognized subspecies), Redside Shiner, Redside Shiner x Speckled Dace Hybrid, Speckled Dace, Utah Chub, Utah Sucker, Westslope Cutthroat, and Yellowstone Cutthroat. The main purpose of the Yellowstone Fisheries Management is to maintain the health and contiuation of these species.

There are five (5) non-native species and one (1) non-native hybrid species. These six species are: Brook Trout, Brown Trout, Cutthroat Trout x Rainbow Trout Hybrid, Lake Chub, Lake Trout, and Rainbow Trout. Yellowstone Fisheries Management is working to control and regulate these non-native species. Lake Trout were illegally introduced to Yellowstone Lake and are having a devastating effect on the native Cutthroat Trout, which in turn affects the whole ecosystem including the wildlife (otters, eagles, bears, osprey, etc.) that have always relied on Cutthroat as a food source.
