<br />COLORADO RIVER RECOVERY PROGRAM <br />FY 2002 ANNUAL PROJECT REPORT <br /> <br />RECOVERY PROGRAM <br />PROJECT NUMBER: 50 <br /> <br />I. . Project Title: Five-Year Experimental Stocking Plan to Evaluate Survival of Various <br />Sizes of Razorback Sucker <br /> <br />II. Principal Investigator(s): Chuck McAda, Project Leader <br />Bob D. Burdick, Fishery Biologist (LEAD) <br />Organization: Colorado River Fishery Project <br />Address: 764 Horizon Drive, Building B <br />Grand Junction, CO 81506-3946 <br />Phone: (970) 245-9319 <br />FAX: (970) 245-6933 <br />E-mail: Chuck_McAda@FWS.GOV <br />Bob_Burdick@FWS.GOV <br /> <br />III. Project Summary: <br /> <br />The study goal was to evaluate the relation between survival of captive-reared razorback <br />sucker and size at release into the Upper Colorado and Gunnison rivers in western <br />Colorado. Specific objectives included determining I) the relationship between various <br />sizes (100-, 200-, and 300-mm) of razorback sucker stocked and their subsequent survival <br />in the wild, and 2) dispersal of stocked fish following release over time. The optimum <br />size(s) of razorback sucker to be stocked into Upper Colorado River Basin rivers were <br />recommended. <br /> <br />No field work was conducted in FY 2002. .A final report was due March 2002. However, <br />preparation of the draft final report was delayed. The draft final report was completed on <br />31 May 2002 and reviewed by the Upper Colorado River Endangered Fish Recovery <br />Program propagation and genetics coordinator. Revisions were made and the report was <br />sent to two peer reviewers and the Biology Committee the first of July 2002 for review <br />and comment. Revisions have been made by the principal investigator from the <br />comments provided by the peer reviewers. A second revised draft final report was sent <br />out on 31 October 2002 to the Biology Committee for additional review. Review of this <br />report and approval by the Biology Committee is anticipated in early-December 2002. <br />Completion and distribution of the final report is anticipated sometime in early-2003. <br /> <br />IV.
