brook trout

The Wyoming Game and Fish Department plans to remove non-native fish from a stream in the Bighorn National Forest, in order to restore a native fish that has nearly died out.

The agency would use a chemical to kill off brook trout and then re-stock the stream with Yellowstone cut-throat trout, which are native to Wyoming.

Assistant Fisheries Management Coordinator Mark Smith says cut-throats have not been able to compete with brook trout, which were introduced to the state in the 1930s. He says nearly 90 percent of the cut-throats in the Bighorns have died off already.
