the river. This effort resulted in the capture of 520 razorback sucker. Six fish died ~ during handling, resulting in the release of 514 razorback sucker to the river. Using the removal method (depletion curve) for estimating population numbers, there were an estimated 749 razorback sucker in the site (95% confidence interval ± 320) (Figure 8). Subtracting 520 from 749, there were still an estimated 229 razorback sucker that remained entering the winter. Razorback suckers were not caught in the site the ~ following spring and carp were the only fish species collected. Dead carp on the shoreline at ice out was evidence of winter kill. Therefore, it is believed none of the razorback sucker remaining in the fall survived the winter. ~ Late summer fish kills were not observed at Above Brennan in 2000, indicating water quality conditions were better than in The Stirrup and Baeser Bend. However, as a precaution water was also pumped into Above Brennan beginning on 18 August. Sampling in early September 2000, resulted in the capture of 32 razorback sucker with 6 recaptures. All of these captures were from the group stocked in 1999. These ~ razorback sucker visually appeared healthier and averaged 149 grams heavier than those from the same age class captured in Baeser Bend. Because of their healthy appearance, razorback sucker captured in Above Brennan were released back into the ~ site to overwinter. Sampling the following spring resulted in the capture of 48 razorback sucker with 14 recaptures. Because the closed population assumption was violated by a connection with the river, population estimates were not generated from either fall t 2000 sampling or spring 2001 sampling. Above Brennan was sampled for the final time late in the summer 2001 and no razorback sucker were caught. Presumably razorback ~ sucker that remained in the site following spring 2001 sampling left the site for the river 13
