Nonnative Fish Management

Predation or competition by nonnative fish species is a serious threat to the endangered fishes and perhaps the most challenging to manage. The Recovery Program is working proactively to meet the challenge of nonnative fish management by removing the most problematic nonnative fishes from rivers, and preventing nonnative fish from entering the river system in areas inhabited by endangered fish. The actions recognize the dual responsibilities of state and federal wildlife agencies to conserve native fish species while providing sportfishing opportunities.
