DENVER — Another rare Colorado River fish has been pulled back from the brink of extinction, the second comeback this year for a species unique to the Southwestern U.S. “It’s a work in progress,” said Tom Chart, director of the Upper Colorado River Endangered Fish Recovery Program. In March, the Fish and Wildlife Service recommended changing the humpback chub from endangered to threatened. State and federal agencies began introducing game fish into the Colorado without realizing they would devour the native fish, Chart said. The Fish and Wildlife Service began capturing the remaining wild razorbacks and moving them to hatcheries to begin rebuilding the population.
