Table 1. Facilities needed to produce bonytail identified in stocking plans, based on <br />pounds per acre of grow-out ponds, and acres available. <br /> Acres on Hand <br />Facility (Stocking Plan) Number to Produce Pounds/acre Acres Needed Hatchery <br />Ponds Grow-out <br />Ponds <br />Mumma (Colorado) 24,000 500 15.9 0.4 35 <br />Wahweap (Utah) 16,280 2,000 2.6 2.8 0 <br />COLORADO PIKEMINNOW <br />Background <br />With access to habitat in the Gunnison River and the Upper Colorado River above <br />Palisade, Colorado, the State of Colorado recommended augmenting these river reaches with <br />Colorado pikeminnow at 150 mm (6 inch) TL. The population of Colorado pikeminnow in the <br />Colorado River is estimated around 700 adults (Osmundson 2001). A manual for culturing <br />Colorado pikeminnow was developed by the Colorado Division of Wildlife (Schler 2001). <br />Approach <br />Broodstock.-A broodstock is maintained at Dexter, and the Recovery Program also <br />considers fish in the Colorado River to serve as a source to create production fish by stream-side <br />spawning, which has met with limited success in the past. The Recovery Program will make an <br />annual request to Dexter to provide 10,000 Colorado pikeminnow fry to Recovery Program <br />facilities. The fry will be distributed equally between the Grand Valley Endangered Fish <br />Facility, Grand Junction, Colorado (Grand Valley) and the Mumma facility. Grand Valley will <br />also continue to attempt stream-side spawning in the Colorado River. Colorado pikeminnow <br />grown to 150 mm TL in excess of the State of Colorado stocking plan will be made available to <br />the San Juan River Recovery Implementation Program. <br />Rearing Location Prior to Stocking.-Grand Valley and Mumma will raise Colorado <br />pikeminnow intensively in tanks on an annual basis. Fish will be maintained in the hatchery <br />4 <br />
