1 38 stocking of Colorado squawfish with coded nose wire tags in the Colorado, Green, and Gunnison rivers has never been evaluated. Question 11: Are you aware of any institutional management programs or large scale approaches that have successfully eliminated an undesirable introduced fish species or reduced their negative impacts on a native fish species within a drainage basin? Thirteen of the respondents replied in the negative to this question. The only successful elimination programs were conducted on smaller, manageable watersheds, and were not comparable to large riverine systems. Again, the only examples included efforts such as restoration of greenback cutthroat trout in headwaters of the South Platte River drainage, Colorado, Gila trout in the Gila Mountains, New Mexico, elimination of grass carp in New Mexico, chemical reclamation of the Virgin River, Utah, for woundfin, Virgin River spikedace, and Virgin River round tail chub, and chemical reclamation of Strawberry Reservoir, Utah. Neither of the Utah efforts have been evaluated for effectiveness of the treatment One respondent suggested the recovery problems being faced for the Colorado River endemic fishes are similar to those faced on the Missouri and Mississippi rivers for species like paddle fish. These problems include monitoring difficulties, pros and cons of nonnative fishes, and habitat changes caused by dams. Question 12: How is your agency, or the state wildlife agency in your area or state attempting to balance demands for sport fishing recreation and demands for conservation of endangered fishes and native fish fauna? Responses suggested the potential conflict of demands between sport fishing recreation and conservation of endangered and native fishes was reflected by conflicting priorities and communication problems between respective sections within management agencies. Agencies cannot begin to resolve the conflict between two special interest groups at the public level until they have established a functional communication process internally to facilitate decision-making at the agency level. It does not appear from comments received that balance between sport fishing recreation and conservation of endangered and native fishes is any more than a concept at present Effective communication between nongame and game biologists and the coordinated review of programs by both sections are still evolving. In Utah, one respondent indicated there does not exist a major conflict over the resource since sport fishing demands are not intense in habitat occupied by the endangered fishes. The sportfishing section within Utah DWR has not promoted or endorsed northern pike as a desirable game fish in the Green River system, and has helped implement regulations prohibiting certain angling methods. The Flaming Gorge project is a main area of interaction between sport and native fish and a level of cooperation has been achieved due mostly to federal requirements. From outside state agencies, the perception was that some management programs appear in conflict An example was given of the use of ponds
