Overwinter survival. <br /> <br />Description of work <br />An ongoing study being conducted by BIO/WEST Inc. under the lead of <br />UDWR. The primary goal of this study is to gain an understanding of <br />there1 ationship between winter river discharges and other important <br />environmental variables and the survival of young fish (particularly <br />Colorado squawfish) in the Green River. The specific objective of <br />the study is to assess overwinter survival and movement of fishes <br />with emphasis on endangered species. Researchers will attempt to <br />re 1 ate effects of releases from FGD to overwi nter survi va 1 and <br />movements. <br /> <br />Methods <br />Fall and spring sampling trips using techniques consistent with ISMP <br />are conducted to assess year class strength of Colorado squawfish <br />and evaluate overwinter mortality. Year class strength is evaluated <br />in light of relevant variables to test hypotheses on overwinter <br />survival of young squawfish. Methods may change if new marking <br />techniques become available as a result of marking investigations <br />being conducted in Study No.4. <br /> <br />Rationale <br />Data collected in this study is necessary for evaluation of effects <br />of winter releases from FGD on young fish. <br /> <br />Deliverables <br />UDWR and BID/WEST wi 11 submi t an annual report at the end of the <br />fiscal year and a final report upon completion of the .study. <br /> <br />1993 Budqet <br />-labor $20,500 <br />-Travel 5,000 <br />-Equipment 1,000 <br /> <br />- Total <br /> <br />j26,500 <br /> <br />Flaming Gorge Studies <br /> <br />24 <br />
