<br />, <br /> <br />I NTRODUCTI ON <br /> <br />Cultural methods for the propagation of Colorado River threatened and <br />endangered fishes have recently been developed at Willow Beach National <br />Fish Hat.chery (NFH) in Arizona and Dexter NFH in New t'1exico. (Toney <br />1974, Hamman 1981 a, 1981 b, 1982a, 1982b). Fry and fingerl i ngs produced <br />at these hatcheries have been distributed to state fish hatcheries in <br />Arizona, California, Utah, and to Hotchkiss NFH in Colorado for rearing <br />prior to stocking and for experimental purposes. University laboratories <br />have used many of these fish in research (Miller et al. 1982). Some <br />hatchery-raised Colorado River endangered fishes have been stocked in <br />the Colorado River in Utah, Colorado and Arizona (Miller, Tyus, & Kaeding <br />1982 and Johnson and Rinne 1982). <br /> <br />The Colorado River Fishery Project (CRFP) completed a three-year study <br />(1979-1981) of endangered fishes 'and recommended procedures to protect <br />and preserve these fish and their habitats (Miller et al. 1981). Based <br />on these findings and recommendations, a draft Conservation Plan (CP) <br />for Endangered Colorado River Fishes has been developed by the Fish and <br />Wildlife Service (FWS) for the Upper Colorado River Basin (UCRB). A <br />part of this plan calls for hatcheries to produce endangered fish to be <br />used in various laboratory-based studies and for reintroduction to <br />augment populations of wild fish. <br /> <br />Strategies outlined in the CP call for the use of hatchery fish; 1) for <br />research/management studies between 1983 and 1996, 2) for stocking <br />Colorado River endangered fishes to increase UCRB stocks after 1987, and <br />3) for the development of a sport fishery for Colorado squawfish in a <br />small reservoir in 1990. Humpback and bony tail ch~bs may also be <br />stocked in the UCRB under the CP if investigations show this to be <br />feasible. <br /> <br />The Colorado River Fishes Recovery Team has begun updating Recovery <br />Plans for the Colorado squawfish and humpback chub and is preparing a <br />plan for the bony tail chub. These plans will be released in 1983. <br />Among the recommendations was the hatchery propagation and reintro- <br />duction of endangered fishes for the purpose of reestablishing several <br />self-sustaining populations of each species in the UCRB and the Lower <br />Colorado River Basin (LCRB). The ultimate goal of such introductions is <br />the delisting or downlisting of these species. <br /> <br />In 1982, the FWS, Endangered Species Office (SE), Region 6 requested <br />that CRFP conduct a feasibility study for a Colorado River endangered <br />fishes hatchery. This request has resulted in the following study <br />report. The study quantifies the need for hatchery-reared Colorado <br />River fishes in the UCRB; based upon the CP, and in the LCRB based on <br />Recovery Plans for Colorado River fishes. The following report summarizes <br />this feasibility study and recommends how to meet this need effectively <br />and economically. An assessment of existing hatcheries' abilities to <br />produce the needed fish was included in this report. t1oreover, new <br />sites and/or facilities were evaluated. <br />
