<br />000196 <br /> <br />#29a: Population Estimate of Humpback Chub in Black Rocks by Chuck McAda. <br /> <br />Continue management and operation of facilities to serve as a primary refuge for <br />endangered fishes of the Upper Colorado Basin. <br /> <br />#127: Monitoring the Colorado Pikeminnow Population in the Mainstem Colorado River via <br />Periodic Population Estimates by Doug Osmundson. <br /> <br />Continue as planned for 2004 and 2005. However, we recommend that to get three years <br />of reliable estimates of acceptable precision (to comply with Recovery Goal monitoring <br />criteria), an additional year be added in 2006 to replace the low-quality 2003 estimate. <br />This decision might wait until after the 2004 and 2005 estimates are in; if these indicate <br />the 2003 estimate is reasonable, perhaps an additional year will not be needed. <br /> <br />#121: Verification of stocked razorback sucker reproduction in the Gunnison River via annual <br />collections of larvae by Douglas Osmundson and Chuck McAda. <br /> <br />Proceed with monitoring as before. Light-trapping effort in 2004 will again be contingent <br />on water levels and availability of sampling sites. An amended scope of work was <br />submitted to expand larval collections downstream into the Colorado River for 2004. <br /> <br />#128a: Abundance Estimates for Colorado pikeminnow in the Middle Green River /Yampa River <br />System by Kevin Bestgen, John Hawkins, Gary White, Kevin Christopherson, Ron <br />Brunson, Mark Fuller, Tim Modde and Thomas P. Nesler. <br /> <br />Complete data analysis and write the final report. The final report will be combined with <br />results for the Green River from downstream ofthe White River to the confluence with <br />the Colorado River. <br /> <br />#128b: Lower Green River Colorado Pikeminnow Population Estimate by Paul BadameIMichael <br />Hudson, Tim ModdelFrank Pfeifer, and Kevin Bestgen. <br /> <br />Analyze data and write final report. <br /> <br />#132: Population estimate of humpback chub in Westwater Canyon, Colorado River, Utah by <br />Paul Badame and J. Michael Hudson. <br /> <br />Electrofishing should be conducted during the first two passes of2004 and 2005. <br /> <br />Radiotelemetry tracking of humpback chub and roundtail chub may help explain <br />movement patterns that have not been documented. <br /> <br />An additional night of sampling should be added at the Upper Cougar site to more <br />adequately sample that area. <br /> <br />2003 Report Recommendations, <br />
