Title of Proposal: <br /> <br />ANNUAL ASSESSMENT OP COLORADO SQUAWPISH REPRODUCTION AND LARVAL ABUNDANCE <br />IN THE LOWER YAMPA RIVER, COLORADO, AND THE LOWER GREBN RIVER, UTAH. <br /> <br />II. Relation to Recovery Program/Ranking Pactors: <br /> <br />This study was started in 1990 and is part of the "Five-Year Flaming Gorge <br />Flow RecOllllllendations Investigations (FGFRI)" ; specifically Element 1 <br />(Reproduction) of the Systematic Data Collection and Research (SDCR) <br />program. The SDCR, which was outlined in detail in the FY-1991 FGFRI <br />proposal, is composed of four interrelated elements and is intended to <br />directly assess effects of seasonal operation of Flaming Gorge Dam on <br />annual reproduction and long-term recruitment of fishes in the Green River <br />system. The four elements include 1) reproduction, 2) age-O survival to <br />fall (age-O recruitment), 3) over-winter survival of young fish (age-l <br />recruitment), and 4) link between recruitment of young fish and <br />recruitment to adult stocks. Integrated studies under FGFRI (i,e., SDCR <br />studies and hypotheses-testing studies; which are intended to aid in <br />interpretation of SDCR results by addressing specific questions) will <br />facilitate determination of factors affecting annual reproduction, <br />abundance, and recruitment of Colorado squawfish (and other fishes) in the <br />Green River basin, <br /> <br />Annual assessment of Colorado squawfish reproduction and larval abundance <br />(this study) is necessary to identify and assess factors affecting annual <br />recruitment, and is directly linked with SDCR Elements 2 and 3 (see <br />description of SDCR Tasks 2, 3, and 4). Interpretation of results of this <br />study will be enhanced by information from hypotheses-testing studies 3 -- <br />"Availability, habitat characteristics, and fish use of spring habitats <br />for Colorado squawfish and razorback sucker in the Green river) and <br />especially 5 (hypotheses - testing Task 5 - - "Integration of field and <br />laboratory studies On aspects of early life biology and development of <br />selected fishes in the Green River system); see specific proposals, <br /> <br />C1 <br />
