<br />DISCUSSION <br />~ Stocked fish total length increased 300% during the first growing season <br /> <br />(Figures 9 - 12 and 15 - 16). As expected, growth in length slowed during the second <br />growing season. However, weight gains continued at nearly the same rate throughout <br />the study (Figures 14 and 18). Growth data collected during this study was consistent <br />with other studies and supports the premise that floodplain wetland habitats are <br />~ important for young razorback sucker. Fish grew rapidly in the highly productive <br />floodplain wetlands, and presumably survival was enhanced as a result of the larger <br />young fish becoming less susceptible to predation (Wydoski and Wick 1998, Lentsch <br />~ 1996, and Osmundson and Kaeding 1989). <br />Population estimates indicate age-1 razorback sucker stocked in 1999 <br />demonstrated good survival in each site during the first year of the study. Estimates <br />were calculated in the fall 1999. First year survival estimates with the narrowest <br />confidence intervals were obtained for Baeser Bend. Razorback sucker survival at <br />~ Baeser Bend was estimated at 52% ± 7% for fall 1999. Survival estimates at The <br />Stirrup and Above Brennan were similar to estimates at Baeser Bend, however, <br />confidence intervals were much wider. Survival estimates were 37% ± 35% in the fall <br />~ 1999. At Above Brennan survival estimates were 56% ± 53% in the fall 1999 (Figure <br />7). Better survival estimates were obtained for Baeser Bend because sampling was <br />t more efficient at Baeser Bend than the other two sites. Large areas of thick dead <br />terrestrial vegetation at The Stirrup and Above Brennan reduced sampling efficiency. In <br />contrast Baeser Bend is more open and had very little dead terrestrial vegetation to <br />hinder sampling. <br />20 <br /> <br />
