Western slope native fish research focuses on three species: flannelmouth sucker, bluehead sucker and roundtail chub. 

Each of these species is estimated to occupy only 45-55 percent of its historic native range in the upper Colorado River basin and all three show downward population trends. 

Thus, research aims to enhance these species' current range and minimize the probability of listing under the Endangered Species Act.
