~Q2Qj~ J. Establish hatchery and wild populations of pure (Type A) greenback cutthroat trout for brood.tack. Efforts will be pursued to establish greenback trout populations in captivity and to identify wild greenback populations that can be used as broodstock to support the establishment of additional greenback populations within the subspecies' historic range. 3.1 Establish a South Platte River wild brood stock. Establish/maintain at least one lake/stream environment within the South Platte River drainage to function as a wild broodstock source. These broodstocke can also constitute one or more of the 20 stable populations under Task 2.0. This Task has been completed; wild greenback populations in Como Creek, Hunters Creek, Bear Lake and Upper Hutcheson Lake are identified as suitable egg sources. 3.2 Establish an Arkansas River wild brood stock. Establish one lake/stream environment within the Arkansas River drainage to function as a practical wild broodstock source. This broodstock may constitute one or more of the 20 stable populations under Task 2.0. This task has been completed. Eggs have been collected from Lytle Pond on Ft. Carson and from South Apache Creek in 1992. Boehmer Reservoir and Native Lake also have the potential to serve as brood stock areas, as well as the historic populations in Cascade Creek. 3.3 Establish captive broodstocks. Establish and demonstrate the successful use of a hatchery propagation program at the USFWS, Bozeman Fish Technology Center, (FTC) Bozeman, Montana, using pure (type A) greenback cutthroat trout. Movement of greenback fry and milt between Bozeman FTC and restoration sites in colorado will be done in accordance with current State and Federal fish disease policies and good fisheries management practices. Use greenback fry from this source to reintroduce greenbacks into candidate habitats as outlined in Task 2.4. In addition to the Bozeman program, another successful hatchery program was demonstrated at the Saratoga NFH in wyoming. Both of these greenback hatchery programs ended in 1992. A hatchery program at the COOW Experimental Hatchery was initiated in 1989. 3.31 Collect and utilize milt from wild populations. Collect and utilize milt from wild populations of pure (Type A) greenbacks for fertilization of hatchery ova to minlmize genetic drift within the hatchery. This task has been completed; milt from 2.
