<br />. <br /> <br />. <br /> <br />duplicates methods used by Valdez et al. 1992 and will determine fish- <br />community changes that have occurred since then, Survival of age-O, <br />hatchery-reared Colorado squawfish stocked into the Gunnison River in 1984 <br />will be assessed. Colorado squawfish equipped with radio transmitters <br />during FY-93 will be followed until their batteries expire, A final report <br />describing the results of the two-year inventory and the movement of radio- <br />equipped fish will be completed. <br /> <br />Title: <br /> <br />Evaluation of Gunnison River flow manipulation upon larval <br />production of Colorado squawfish in the Colorado River <br /> <br />Scope of Work Number: B <br /> <br />Tasks: I, 3, 5, and 6 <br /> <br />Cooperating Agencies: Utah Division of Wildlife Resources and Colorado <br />Division of Wildlife <br /> <br />FY 94 Cost: $82,800 <br /> <br />Study Summary: Reproduction will be assessed using drift-net sampling at <br />six sites. Near shore samples will be taken daily from June through early <br />August. Larval fish numbers will be compared with ISHP data to assess <br />survival of young Colorado squawfish. <br /> <br />Title: <br /> <br />Evaluation of Gunnison River flow manipulation upon availability <br />and quality of nursery habitat for Colorado squawfish in the <br />Colorado River <br /> <br />Scope of Work Number: C <br /> <br />Task: 2 <br /> <br />Cooperating Agencies: Utah Division of Wildlife Resources, U.S, Fish and <br />Wildlife Service <br /> <br />FY 94 Cost: $65,500 <br /> <br />Study Summary: Two study sections will be selected within the reaches <br />sampled by ISHP. Studies in the lower river will concentrate on habitats <br />occupied by YOY Colorado squawfish. All backwaters within the study <br />sections will be sampled intensively in July and September. Physical and <br />biological habitat characteristics will be measured at each backwater to <br />distinguish habitat variables that are important to Colorado squawfish, <br />Quality and quantity of backwaters will be related to streamflow <br />characteristics. Because few Colorado squawfish have been collected from <br />the upper river in recent years, studies there will concentrate on <br />geomorphology of the upper Colorado River. Flow necessary to maintain the <br />existing habitat will be assessed. <br /> <br />Title: <br /> <br />Flow effects on young-of-the-year Colorado squawfish and sympatric <br />species <br /> <br />7 <br />
