and fish movement with emphasis on endangered species. <br />Researchers will attempt to relate effects of flows from Flaming <br />Gorge Dam to overwinter survival and overwinter movements. <br />Sampling will involve the capture and marking of young squawfish <br />and evaluation of the effectiveness and impact of the marking <br />methods. After selection of a marking technique, a sample of <br />young Colorado squawfish would be marked and released in a <br />selected study area. Survival and movement of fish in response <br />to winter and spring flows would be evaluated on the basis of <br />subsequent recaptures. <br />Data collected in this element would be particularly valuable <br />for evaluation of the effect of winter flow releases from <br />Flaming Gorge on young fish. <br />Deliverables: <br />UDWR will submit an annual report at the end of the fiscal year <br />and a final report upon completion of the task. <br />Budget': <br />-Labor $19,000 <br />-Travel $ 51000 <br />-Equipment $ 1,000 <br />-Total $25,000 <br />Task 5. Evaluation of the link between recruitment of young <br />Colorado squawfish and recruitment to adult stocks. <br />Description of work: <br />This task will be conducted by UDWR and LFL researchers under <br />the lead of UDWR. The primary goal of this task is to determine <br />if there is differential growth between different year classes <br />of Colorado squawfish and if so how size of young fish affects <br />overwinter survival and subsequent recruitment to adult stocks. <br />Previous studies on other fish have shown that the number of <br />circuli to the first growth check on scales can be used to <br />identify differential survival within year classes. This study <br />will evaluate if the technique is applicable to squawfish. If <br />differential survival between year classes can be documented <br />this research may indicate minimum size YOY Colorado squawfish <br />must achieve to successfully overwinter and will associate first <br />and second year survival with annual flow events. <br />Sampling of adult fish will be conducted to coincide with ISMP <br />spring sampling, but would be expanded beyond current scope of <br />ISMP to help determine if ISMP procedures are giving accurate <br />indices of adult fish stocks. Incorporated into this expanded <br />sampling effort would be collection of more fishery-type data <br />'Does not include FWS overhead <br />B4
