STOCKING OF NONNATIVE FISHES THAT DO NOT PRESENTLY OCCUR IN THE UPPER <br />COLORADO RIVER BASIN <br /> <br />1, The States and the Service recognize that introducing new fish <br />species, including hybrids. into an ecosystem can result in <br />unanticipated impacts on native fishes. For this reason, few <br />proposals, if any. to introduce new fish species or hybrids into <br />the Upper Basin are anticipated, Introduction of new species will <br />generally be discouraged. <br /> <br />Minimum criteria for stocking will include: 1) no stocking of <br />isolated ponds within the 50-year floodplain and 2) if the water <br />has an outlet. it must be screened or managed to control <br />escapement, Stocking should be "confined to areas where absence of <br />potential conflict with rare or endangered species can be <br />demonstrated" (U.S. Fish and Wildlife Service 1987), <br /> <br />2, Proposals to stock fishes that do not presently occur in the basin <br />will be subject to case-by-case review by the State wildlife agency <br />and the Service and will include the following minimal information: <br /> <br />A, The purpose and location of the proposed stocking, <br /> <br />B, The species. numbers. and rationale for selecting the species. <br /> <br />C, The potential for escapement. the potential for survival in <br />critical habitat if escapement occurs. and control measures <br />that could be implemented to reduce the risk of escapement, <br /> <br />0, The potential for impact to threatened and endangered species <br />and the specific measures available to remedy any impacts that <br />may occur including their feasibility and likelihood of <br />success, <br /> <br />E, A plan for monitoring the effects of stocking nonnative fishes <br />on the endangered Colorado River fishes, <br /> <br />3, Any proposal to introduce new fish species into the Upper Basin <br />shall also follow the rationale and justification of the American <br />
