Roundtail Chub (Gila robusta)

The Roundtail Chub is native to Nevada's Colorado River drainage in the southern part of the state, primarily in the Virgin and Muddy river systems. Populations have declined significantly due to habitat alteration and competition from non-native species. The species is listed as threatened under the Endangered Species Act, and Nevada Department of Wildlife cooperates with federal agencies on conservation efforts. Anglers should practice catch-and-release if encountered, though targeted fishing is uncommon given the species' protected status and limited distribution.
