<br />and PIT tagged. Fish caught in the outgoing trap were released into the river and any <br />~ razorback sucker caught in the incoming trap were released into the floodplain site. <br />Monitoring dispersal in the river <br />Monitoring of dispersal of floodplain stocked razorback sucker in the Green River <br /> <br />was done by analyzing capture and tagging data of razorback suckers captured from <br />sampling efforts of Abundance Estimates of Colorado pikeminnow and Northern pike <br />~ control in the middle Green River. This data was analyzed to determine if the razorback <br />sucker captured was a wild fish, hatchery produced fish stocked in the river, or a <br />hatchery produced fish stocked into a floodplain site. This analysis is based on the <br />~ premise that all age-1 hatchery produced razorback suckers stocked into the floodplain <br />were tagged with a coded wire tag and all razorback suckers stocked into the river are <br />PIT tagged. A fish was considered probable of being stocked into a floodplain site if it <br />did not have a PIT tag, was not scanned or scanned negative for coded wire tags, and <br />was within the size range of positive floodplain fish. <br /> <br />RESULTS <br />[, <br />Survival <br />At The Stirrup, five days of sampling with fyke nets and one day of electrofishing <br />resulted in the capture, PIT tagging, and release back into the site of 101 razorback <br />~ sucker. Following this initial tagging effort one day of "scare and snare" sampling <br /> <br />resulted in the capture of 31 razorback sucker with four recaptures. Based on these <br />captures, the razorback sucker population in The Stirrup was estimated at 783 fish or <br />10 <br />L <br />
