<br />would be released per stocking site. <br />1. Post-stocking activities include biological and genetic monitoring <br />and evaluation of released fish. Such evaluations are vital to <br />determine if the stocking was a success or failure, if biological <br />information obtained through experimental stocking is aiding <br />recovery, and if additional stocking is warranted. A monitoring and <br />evaluation program is also necessary to determine the genetic <br />impacts stocked fish may have on wild fish stocks within and beyond <br />the area of directed activity. At the time of stocking, fish would <br />be equipped with radio transmitters and released. After release <br />fish would be monitored periodically prior to, during, and following <br />the spawning period. Post-stocking dispersal, movement, and <br />habitat-use information would also be obtained from these fish. The <br />spawning condition of adult razorback sucker captured during the <br />spawning period would be noted. Standard, quantitative surveys <br />would be performed annually for stocked fish. Recaptured fish would <br />be checked for the presence of a PIT tag. Recaptured tagged fish <br />would provide information on survival, movement, post-stocking <br />dispersal, and age and growth information useful in development of <br />aging techniques for wild fish. Verification of successful spawning <br />and recruitment would be conducted annually by sampling in and <br />around suspected spawning areas and downstream reaches following the <br />suspected spawning period. <br />8. The importance of developing and defining clear, objective recovery <br />goals for razorback sucker cannot be over stressed. They are of <br />fundamental importance because they are the criteria against which <br />40 <br />41 <br />4
