<br />OOZ05'! <br /> <br />3. Water temperature of 5-8C by early July. <br />4. Adequate water flows. <br />5. Ability to sustain more than 500 adult fish and 22 kg/ha of <br />biomass. <br />6. Ability to sustain reproduction. <br /> <br />2.3 Consult with landowners or aaencies responsible for land manaaement <br />of candidate habitats. Determine if the establishment of a <br />greenback cutthroat trout population in a candidate area would be <br />compatible with landowner or agency management goals. <br /> <br />2.4 Prepare habitats listed in Tables 6 and 7 for reintroduction. Carry <br />out remedial actions necessary and appropriate to make candidate <br />waters listed in Tables 6 and 7 suitable for the introduction of <br />pure (Type A) greenback cutthroat trout. Aquatic habitats that have <br />been selected for the introduction of greenbacks may be lacking in <br />some phase of preferred or essential habitat requirements. Special <br />emphasis should be given to Arkansas River projects (Table 7), since <br />only two stable reproducing populations currently exist in this <br />drainage. <br /> <br />2.41 Conduct habitat manipulation. If necessary and appropriate, <br />enhance candidate habitat to restore pool/riffle ratios, <br />riparian vegetation, spawning,habitat, water quality and <br />protection from excessive disturbance. <br /> <br />2.42 Construct or improve barrierCs}. Although natural fish <br />migration barriers are preferred, some areas may require the <br />construction of artificial barriers or improvement of existing <br />barriers. <br /> <br />2.43 Remove all non-native salmonids. Use piscicides to remove all <br />non-native salmonids from the candidate habitats. Review the <br />success of this removal and repeat the application of <br />piscicides, if necessary. special emphasis should be given to <br />completing removal of non-native salmonids in candidate <br />habitats within the Arkansas River drainage. Allow treated <br />habitats to remain fishless for a minimum of 6 months prior to <br />proceeding with the reintroduction of greenbacks and other <br />native fish (Task 2.5). <br /> <br />2.5 Introduce Dure ITvce Al areenback cutthroat trout. <br />Introduce pure (Type A) greenback cutthroat trout into the candidate <br />waters using the greenbacks most representative of the drainage <br />being stocked. Greenback cutthroat trout populations introduced <br />within the South Platte drainage (Table 6) should be established <br />with trout from Como Creek, South Fork of the Cache La Poudre River, <br />Hunters Creek, 'Upper Hutcheson Lake, their descendants, or from yet <br />to be determined Type A South Platte populations. <br /> <br />Greenback cutthroat trout populations established within the <br />Arkansas drainage (Table 7) should be established with trout from <br />Cascade Creek, South Fork Apache Creek, their descendants, or from <br />yet to be determined Type A Arkansas River populations. <br /> <br />2.51 Use acorocriate stockina rates for fish from wild copulations. <br />Stocking rates for greenbacks from wild populations should be <br />100-200 sub-adults or adults per site, with 200 being the most <br />desirable number. Removal of any greenbacks from pure (type A) <br /> <br />24 <br />
