Project Summary: <br /> <br />This project monitors populations of endangered fishes in <br />Utah. The following objectives have been outlined for <br />post-larval, late juvenile/adult Colorado squawfish: <br /> <br />) <br /> <br />1. Develop annual indices of relative abundance. <br />2. Determine populations trends. <br />3. Determine relationships between these trends and other <br />environmental parameters. <br />4. Develop annual indices of relative abundance of <br />sympatric species. <br /> <br />IV. Study Schedule: <br />a. Initial year: <br />b. Final year: <br /> <br />1986 <br />ongoing <br /> <br />V. Relationship to RIPRAP: General Recovery Program Support <br />Action Plan, V.A.1. Conduct standardized monitoring <br />program. <br /> <br />VI.Accomplishments of FY 97 Tasks and Deliverables, Discussion of <br />Initial Findings and Shortcomings: Collection and <br />computerization of adult/juvenile and young of the year <br />sampling as delineated in the ISMP handbook. <br /> <br />SUMMARY OF ADULT ISMP SAMPLING - LOWER GREEN AND COLORADO <br />RIVERS <br />The 1997 annual ISMP adult Colorado Squawfish <br />electrofishing was conducted from May 1 through May 16 on <br />the Colorado and Green Rivers. The Wildcard Reach (WC) (GR <br />RM 24-14) was chosen because it is at the midpoint between <br />our lowest Green River reach (5) and the confluence with <br />the Colorado River. Flows were considerably higher than <br />usual, at 23,700 to 26,400 cfs. The Green River was flowing <br /> <br />1 <br />
