29 the Rio Grande basin due to widespread distribution and abundance. Sheepshead minnow and plains minnow were identified as specific problems in the Pecos River basin (New Mexico-Texas ). Several respondents indicated they were not sure, that introduced fish have not been determined to be problematic, or that they could not pinpoint any problematic species at present One respondent considered this question to be too broad; another considered it to be conjecture. One respondent indicated he did not have time to answer this question. Question 7: Do any of the introduced fish species support sport fisheries, and are these fisheries large, moderate, inconsequential? Wildlife agencies are increasingly faced with potentially conflicting demands of providing sport fisheries as well as maintaining native fish populations in their natural habitat The intent of this question was to point out what appears to be at stake for wildlife agencies on the sport fishery side of the issue as they pursue the recovery of endangered native fishes. If a gamefish species is determined to present an unacceptable threat to the recovery of endangered fish species, polarity of the management issue will intensify with the popularity of the gamefish and size of associated fishery. Conversely, attempts to negatively manage carp and small cyprinids to benefit native fishes will be met with indifference or applause by the public since they have no sport fishery value. Only three respondents indicated introduced species supported no sport fisheries in the Colorado River Basin. Presumably these persons were referring to riverine fisheries exclusively. Channel catfish Several respondents considered this species to provide moderate level fisheries overall in the Colorado River Basin. One respondent considered channel catfish to be probably the most popular riverine gamefish present, but another considered their populations were generally unexploited overall. In Utah, channel catfish fisheries in the Green and Colorado rivers were considered moderate. One respondent considered catfish fisheries in Utah to be inconsequential from an economic perspective while another considered this species to provide substantial opportunity locally in Utah near towns like Vernal and Moab. In Colorado, channel catfish fisheries were considered moderate to large in the Colorado, Gunnison, White, Yampa, Dolores, and Little Snake rivers. Differences in assessment were noted between respondents for all these rivers in Colorado. The Little Snake River catfish fishery was deemed inconsequential by one respondent. In New Mexico, fisheries for this species were considered large overall, but small in the San Juan River due to low public access. J
