<br />Approach <br />Broodstock,-In ihe past few years, Dexter has been unable to meet our requests for <br />bonytail fry due to other commitments in the lower basin, The Recovery Program will make an <br />annual request to Dexter to provide 70,000 bonytail fry to Recovery Program facilities, <br />The Recovery Program will continue to develop a broodstock based on year classes at <br />Wahweap, Wahweap should begin to produce bonytail required by the Recovery Program to <br />ensure that the Recovery Program is meeting the production demands of the stocking plans, <br />Rearing Location Prior to Stocking (see Table I ).-Mumma wi11 raise bonytail to be <br />stocked in river reaches identified in the State of Colorado stocking plan, Mumma would receive <br />fry from Dexter in the spring and grow intensively in tanks until the fall of the first year, <br />Bonytail would then be transferred to grow-ant ponds for the second growing season, Assuming <br />that these grow-ont ponds can produce 500 ponnds of fish per acre, 15,9 acres are required on <br />annual basis to produce 24,000 bonytail that are greater than 200 mm TL and weigh abont 150 g, <br />The Mumma facility and :issociations have over 35 acres of grow ponds, First year growth <br />would occur in tanks at the facility, whereas second year growth would occur in grow-out ponds, <br />Wahweap will produce bonytail for stocking into the Green River Subbasin, Assuming <br />that the hatchery ponds can produce 2,000 pOlmds offish per acre (e.g" feeding, warm water, and <br />a longer growing season), 2,6 acres are required on annual basis to produce 16,280 bonytail that <br />average 200 mm TL and weigh about 150 g, Wahweap currently has 2,8 acres of ponds <br />available. In the past, Wahweap has been able to raise up to 80,000 bonytail for stocking ranging <br />in size from 120 to 180 mm TL. <br />Tagging,-All fish to be stocked will be PIT -tagged (Passive Integrated Transponder) to <br />better evaluate the stocking plan and its various aspects (e,g" survival, growth, stocking location, <br />and lot survival evaluation), The cost would be approximately $151,050 to PIT-tag a total of <br />40,280 bonytail, which wonld occur in the autumn of the second ye:ir of growth for both Mumma <br />and Wahweap facilities, <br /> <br />3 <br />
