Wildlife biologists in Utah are trying to bolster the state’s population of roundtail chub, a fish endemic to the Colorado River system. The fish is listed as a sensitive species in Utah due to habitat loss and competition with invasive species. About 30 round tailed chub were released recently into the Old City Park pond in Moab as part of a statewide project to boost the native fish population. Tyler Arnold, a wildlife biologist with the Division of Wildlife Resources in Utah, says roundtail, like many of our native species in the Colorado River system, have been on the decline.
