This task is completed. A <br />mixed brook trout-greenback cutthroat trout fishery exists within <br />the beaver pond habitat of Hidden Valley Creek, RKNP. This area was <br />opened to artificial lure catch-and-kill angling for brook trout and <br />catch-and-release angling for greenbacks to determine if such <br />special regulations give a competitive edge to greenbacks. This <br />angling program did not result in a significant long-term <br />improvement in the Hidden Valley greenback population, although it <br />may have slowed the decline of the greenback population that would <br />have otherwise resulted due to the co-occurrence of brook trout. <br />Further information on this angling program is discussed in the <br />Angling section on page 48. <br /> <br />4.2 Imclement catch-And-release areenback fisheries croarame on public <br />lands. This task is completed. Areas opened to catch-and-release <br />fishing are listed in Tables 1-4. Monitoring is needed in these <br />areas to determine angler success rates and population status. The <br />purpose of this task is to allow sport fishing for greenbacks, and <br />therefore engender public support for further reintroductions of <br />greenbacks, without impacting the stability of greenback <br />populations. <br /> <br />4.3 Complete research stockina and anQlinQ proarams. Research on <br />stocking and angling programs will be conducted using surplus <br />captive reared greenbacks to explore their response to a wide range <br />of habitat types, angler pressures and appropriate angling <br />regulations. Research stocking sites are listed in Tables 8 and 9. <br /> <br />28 <br />
