<br />CONCLUSIONS <br /> <br />• Razorback sucker and bonytail larvae survived and grew well in a reset floodplain <br />with a simulated predator load. <br />• Survival in the control enclosure, without nonnative fish, was much higher 9.8% <br />for razorback sucker and 17.1 % for bonytail. <br />• The minimum density needed to achieve a target survival level was not <br />established. <br />RECOMMENDATIONS <br /> <br />• Continue to manage floodplains based on the reset theory. Even with abundant <br />non-native fish predators these habitats are important to endangered fish and <br />should be used for recovery. <br />• Continue efforts to better define the density relationship between larval <br />endangered fish survival and non-native fish under natural conditions. <br />• During the next high flow year, introduce larval razorback suckers into floodplain <br />sites that are void of nonnative fish to test this theory under more natural <br />conditions. <br />• Evaluate methods to improve larval razorback sucker entrainment including <br /> <br />connection configuration, location, and river flows. Entraining large numbers of <br />larvae may be needed for recovery. <br />• Evaluate conditions necessary for razorback suckers and bonytail to recruit back <br />to the river. <br /> <br />20 ~ <br />
