Implement flow recommendations <br />provided by researchers that would likely benefit razorback sucker. <br />Restore wetland habitats adjacent to the river corridor in river <br />reaches previously occupied by razorback sucker. Provide access for <br />larval razorback sucker to wetland habitats during the late spring <br />when larval razorback sucker are drifting downstream following <br />spawning. Modify man-made levees that block natural river features <br />such as oxbows to allow fish access during runoff. Discourage <br />future levee construction designed to control flooding along river <br />corridors in river reaches targeted for razorback sucker recovery. <br />Recover razorback sucker from grow-out ponds. Fish would be checked <br />for the presence of a PIT tag. Initially, about 30 to 60 hatchery- <br />produced fish would be required. Ten to twenty adult fish (an equal <br />number of males and females) each implanted with long-term radio <br />transmitters would be stocked per selected stream reach in early <br />spring. <br />Evaluate and document the success or failure of experimental stocked <br />fish. If failure occurs, attempt to determine the cause(s). <br />Initially, stocked fish would be monitored with radiotelemetrv to <br />determine post-stocking dispersal, survival, and habitat use. If <br />subsequent stocking occurs, long-term monitoring would have to be <br />conducted to assess survival, spawning, and recruitment success. <br />Genetic monitoring would be conducted to measure potential genetic <br />43 <br />10
