<br />RECOMMENDATIONS <br />1. Measurement of backwater surface area with aerial video, as currently conducted, <br />does not add substantially to mean CPE as an index to relative abundance of YOY <br />Colorado squawfish in fall and therefore should not become a permanent <br />component of the Interagency Standardized Monitoring Program. <br />2. Important backwater measurements may be identified during the Nursery Habitat <br />study currently being conducted by UDWR. If these parameters can be used to <br />improve reliability of mean CPE as an annual index of abundance and can be <br />identified from the air, aerial video should be reevaluated as part of ISMP. <br />3. Aerial video has provided important information about physical habitat in the Green <br />and Colorado rivers and can continue to do so. Aerial video could become a <br />valuable component of channel monitoring studies or other investigations requiring <br />measurement of large-scale channel features. <br />ACKNOWLEDGMENTS <br />Many individuals participated in collecting the data reported here. Principals among the <br />many investigators collecting YOY Colorado squawfish data include Bill Bates, Tom Chart, <br />Steve Cranny, Brandt Gutermuth, Miles Moretti, and Melissa Trammel from the Utah <br />Division of Wildlife Resources; Bill Elmblad, Pat Martinez, and Tom Nesler from the <br />Colorado Division of Wildlife; Doug Osmundson from the Fish and Wildlife Service; and <br />Rich Valdez, Bill Masslich, and Bryan Cowdell from BIO/WEST. Kathy Fenton and Mike <br />Pucherelli, from the Bureau of Reclamation, collected and interpreted the aerial-video data. <br />Tom Chart, Doug Osmundson, and Rich Valdez provided comments on an earlier version of <br />this report. <br />22 <br /> <br /> <br />1 <br /> <br /> <br /> <br /> <br /> <br /> <br />1 <br /> <br /> <br /> <br /> <br /> <br />11 <br /> <br />
