Fishing in Yellowstone

Yellowstone National Park is managed to protect cultural and natural resources and outstanding scenery, and to provide for visitor use. Fishing has been a major visitor activity for well over a century. Because of this history, fishing continues to be allowed and can complement, and in some cases even enhance, the park's primary purpose to preserve natural environments and native species.

Fisheries Science in Yellowstone

Native cutthroat trout are the most ecologically important fish of the park and the most prized, and highly regarded by visiting anglers. Several factors, mostly related to exotic species introductions, are threatening the persistence of these fish. The Yellowstone Fisheries Program strives to use best available science in addressing these threats, with a focus on direct, aggressive intervention, and welcomed assistance by visiting anglers.
