Humpback Chub Translocations and Non-Native Trout Removal in Grand Canyon National Park

The Colorado River that runs through Grand Canyon National Park is home to many endemic species of fishes. Yet, extensive water withdrawals and hydroelectric dam development have drastically altered riverine conditions of the Colorado River, including the populations of its unique fish species. Further, introduced fish such as trout are well-adapted to these modified conditions, outcompeting and preying on many of the threatened and endangered native species found in Grand Canyon National Park. Today, the Humpback Chub is federally listed as Endangered. To protect this species, fishery biologists and park managers in Grand Canyon National Park are working to expand local populations of Humpback Chub through translocations and through removing non-native trout from headwater tributaries.
