<br />. <br /> <br />. <br /> <br />effect on game and food fishes or waterfowl, on aquatic plants <br />and public health. The published information on the species <br />should be reviewed and the species should be studied in <br />preliminary fashion in its biotype. <br /> <br />d. PUBLICITY AND REVIEW. The subject should be entirely open and <br />expert advice should be sought: It is at this point that <br />thoroughness is in order. No importation is so urgent that it <br />should not be subject to careful evaluation. <br /> <br />e. EXPERIMENTAL RESEARCH. If a prospective import passes the <br />first four steps, a research program should be initiated by an <br />appropriate agency or organization to test the import in <br />confined waters (experimental ponds, etc.) (Note: research will <br />usually be considered only when existing research and <br />literature is lacking or insufficient to address a proposal). <br /> <br />f. EVALUATION OR RECOMMENDATION. Again publicity is in order and <br />complete reports should be circulated amongst interested <br />scientists and presented for publication. (Note: publishing <br />schedules of technical journals frequently will not allow <br />timely review of stocking proposals). <br /> <br />g. INTRODUCTION. With favorable evaluation, the releases should <br />be effected and monitored, with results published or <br />circulated. <br /> <br />Proposals to introduce a nonnative fish species identified in Table 2 <br />will also thoroughly address each of the elements of case-by-case <br />proposals described in Part II, B, of these Procedures. <br /> <br />III. INTRODUCTION OF NONNATIVE AQUATIC SPECIES NEW TO THE UPPER BASIN. <br /> <br />The Service and the States recognize that introducing new species into <br />an ecosystem can produce unanticipated impacts to native species. <br />Because of the potential impacts of new introductions, few proposals to <br />introduce new species or hybrids into the Upper Basin are anticipated. <br />In the event that such a proposal is submitted, it would need to be <br />ecologically justified and evaluated with respect to impacts to <br />threatened or endangered species and recovery efforts for these species. <br />The justification and evaluation will be modeled after Section 5, <br />elements a-g, of the American Fisheries Society Position Statement on <br />the Introduction of Aquatic Species, as described above. Proposals to <br />introduce new nonnative fish species into the Upper Basin will also <br />thoroughly address each of the elements of case-by-case proposals <br />described in Part II, B, of these Procedures. <br /> <br />7 <br />
