<br />APPENDIX A <br /> <br />GUIDELINES FOR DISPOSITION OF CAPTIVE-REARED ENDANGERED FISH <br /> <br />A. Backqround. Many propagation activities may produce more fish than are <br />needed to meet specified requirements. This additional production allows <br />the hatchery manager to compensate for unknown or unpredictable attrition <br />rates to ensure that specified requirements are met. These guidelines <br />provide the protocol for disposition of such fish. <br /> <br />Planned captive propagation minimizes the production of endangered fish <br />that will be excess to Recovery Implementation Program (Program) needs <br />and reduces demands on resources (i.e., people, funds, and space). The <br />number of endangered fish that are reared for Program needs depends UpOI1: <br /> <br />1. Captive propagation goals and objectives <br />2. Breeding strategy or mating system used <br />3. Fecundity of the endangered fish <br />4. Anticipated mortality during culture <br />5. Method used to culture endangered fish <br />6. Uncertainty of production during captive culture, and <br />7. Availability of culture facilities <br /> <br />"Stocking Plans" and annual "Scopes of Work" that are required by the <br />Program should be prepared well in advance of projected field or <br />laboratory studies so that endangered fish needs can be incorporated into <br />planned production. This is especially important if large or mature <br />endangered fishes are needed for the studies. For example, approximatel', <br />5 years are needed to produce mature bonyta il and humpback chubs and 7 <br />years are needed to produce adult razorback suckers and Colorado <br />squawfish. <br /> <br />All endangered fish propagation will be done in accordance with Progran, <br />"Genetics Management Guidelines" (i.e., philosophy, goals, and general <br />procedures for maintaining genetic diversity similar to wild stocks), <br />"Genetics Management Plan" (i.e., classification of endangered fish <br />species or stocks and establishing priorities using information on status <br />and trends), and 'Stocking Plans" (i.e., specific details on species, <br />specific stocks of fish, numbers of fish, size[s], time of stocking, and <br />method[s] to evaluate stocking). <br /> <br />All wild endangered fish used to develop broodstocks for captive <br />propagation will be released back into the wild \Ihen pedigreed family <br />lots of their progeny have been established. <br /> <br />B. Procedures for Disposition of Captive-Reared Endanqered Fish. Production <br />targets are based on the numbers of fish that were identified for <br />specific Program needs. Under normal operating procedures, unfit fish <br />(e.g., hybrids, genetically deformed, those with untreatable contagious <br />diseases, etc.) will be euthanized following accepted protocol of the <br />fisheries profession. Fish identified as surplus to Program requirements <br /> <br />15 <br /> <br />, <br />
