A feasibility study of DNA fingerprinting to determine the relatedness of captive-reared razorback suckers will be completed with a target date of June 30, 1996). If this genetic technique provides the tool to ensure that family lots are unrelated, adults of unknown pedigrees that are presently in captivity may be used for broodstock. In addition, 6,000 wild larval fishes were placed in a pond at the Ouray National Fish Hatchery to obtain razorback suckers for broodstock development and stocking. These larvae included a mixture of species, including the flannelmouth and bluehead suckers. One thousand (1,000) sucker fry (approximately 70 mm TL) were collected from the pond on April 10, 1996. These fish could not be identified to species without undo stress. Therefore, they were released into another pond on the Ouray National Fish Hatchery. After the second growing season (October, 1996), the fish will be captured and identified to species. Surviving razorback suckers will be used for broodstock development or stocked into the Middle Green River, depending on whether they are unrelated based on DNA fingerprinting. Based on expected survival rates and proportions of razorback suckers in previous sampling and identification efforts, it is estimated that about 25 razorback suckers would survive until October, 1996. B. Razorback Sucker - Upper Colorado River Stock. Razorback suckers from Upper Colorado River, Etter Pond, Colorado River Arm of Lake Powell, and San Juan River Arm of Lake Powell will be used to develop a broodstock for the Upper Colorado River. There are too few fish remaining in the wild to develop a broodstock from the Upper Colorado River. The consensus of the Genetics Panel and upper basin biologists during a meeting held on razorback suckers in September, 1994 was that the broodstock should be developed from a mixed stock (Wydoski 1994b). Eighteen wild adult razorbacks are in captivity at the Grand Valley Endangered Fish Facility. Progeny that are excess to broodstock development will be used for augmentation stocking in Colorado River reaches that still contain razorback suckers and for restoration stocking in river reaches above barrier dams where the species has been extirpated. Emphasis will continue on stocking these fish into the Gunnison River in 1996. The Colorado Division of Wildlife is working on a plan for restoration stocking of razorback suckers upstream of the diversion dams on the Colorado River. During 1996, additional wild adult razorback suckers from the Upper Colorado River and Lake Powell will be collection for continued development of the Upper Colorado River broodstock. On January 23, 1996, the Biology Committee members agreed that wild adult fish could be collected by Recovery Program participants during other Program funded studies so additional funds from Recovery Program Project No. 29e would not be needed. The FY 1996 scope-of-work for Project No. 29e was revised for the collection of wild razorback 6
