0 <br />Approximately 97,000 hatchery-reared, fingerling Colorado <br />squawfish were stocked into Kenney Reservoir from 1988-1990 in an <br />attempt to establish a Colorado squawfish sportfishery (Trammel <br />1991) by the Colorado Division of Wildlife (CDW). These fish <br />either moved over Taylor Draw Dam and dispersed downstream into <br />the White River or survival of these fish in the reservoir was <br />low. Very few of these fish have been captured in subsequent <br />sampling efforts in the reservoir or downstream of the dam in the <br />White River. <br />An alternative to establishing a squawfish hatchery-stocking <br />program upstream of a river barrier is to provide fish passage to <br />the existing wild squawfish population. Upstream passage is <br />currently being proposed for the Redlands Diversion on the <br />Gunnison River, Colorado. However, it is unknown whether adult <br />Colorado squawfish would utilize a passage facility and move <br />upstream past Taylor Draw Dam. <br />There were three major objectives to this study: 1) <br />determine the status of the wild adult Colorado squawfish <br />occupying the tail-waters downstream of Taylor Draw Dam, 2) <br />assess any species composition changes over time in the White <br />River, 3) conduct a follow-up evaluation of the hatchery-reared <br />Colorado squawfish stocked in Kenney Reservoir. Specific study <br />tasks were to: <br />o determine the abundance, movement, and home-range <br />preference of adult Colorado squawfish congregating <br />downstream of Taylor Draw Dam and upstream of Kenney <br />Reservoir. <br />o determine the seasonal macro-habitat use of Colorado <br />squawfish in the White River. <br />0 <br />o determine changes in species composition, relative <br />abundance, and distribution of native and non-native <br />fishes in the White River downstream of Taylor Draw <br />Dam. <br />o determine the presence, abundance, growth, and habitat <br />use of hatchery-reared Colorado squawfish in the White <br />River. <br />11 <br />0 <br />2 <br />0
