Yellowstone Cutthroat Trout
Yellowstone cutthroat trout are the most widespread native fish in the park.
Westslope Cutthroat Trout
Historically the most abundant and widely distributed subspecies of cutthroat trout throughout the West.
Making a comeback due to park restoration efforts.
Lives in rivers and streams with deep pools, clear and clean water.
Mottled sculpin live in shallow, cold water throughout Yellowstone except the Yellowstone River above Lower Falls and in Yellowstone Lake.
Suckers are bottom-dwelling fish that use ridges on their jaws to scrape flora and fauna from rocks.
Catch a Fish
Be a responsible angler and understand the regulations before you come.
Clean, Drain, and Dry
Protect park waters by preventing the spread of aquatic invasive species.
