<br />,. It ') <br />tJ "'j; \ <br />Objectives: <br /> <br />1.) Determine habitat use, possible spawning areas, survival, and growth rates for hatchery- <br />reared razorback sucker in the wild. <br /> <br />2.) Determine if hatchery-reared razorback sucker can lead researchers to wild fish. <br /> <br />3.) Determine feasibility of using hatchery-reared razorback sucker to augment wild <br />populations or repopulate historic habitat. <br /> <br />Methods: <br /> <br />Objective 1.) Electrofishing, seining, trammel netting and radio telemetry will be used to <br />determine what types of habitats stocked razorback sucker are using. Detailed habitat information <br />on substrate, depth, cover, velocity, and relation of this habitat to other habitats (riffle, pools, <br />main and secondary channels, backwaters, shore, etc.) will be recorded. Water quality parameters <br />including dissolved oxygen, water temperature, conductivity, and pH will be measured at each <br />location. Growth, reproductive status, and health information will be collected as welL General <br />movement patterns will be determined through radio telemetry. <br /> <br />Objective 2.) If wild fish are collected during sampling, they will be PIT -tagged, weighed, <br />measured, and radio-tagged if appropriate. Tissue samples for contaminants analysis will be <br />taken. <br /> <br />Objective 3.) Displacement, general health, and survival of stocked fish will be examined to <br />determine if using hatchery-reared razorback sucker for augmentation of wild populations is a <br />feasible option. <br /> <br />The Service will have the lead for the razorback sucker experimental stocking and monitoring and <br />other cooperating agencies will provide personnel and equipment as needed. <br /> <br />Budget: FY-97 <br /> <br />Personnel <br />1 GM-13 Supervisor <br />1 GS-ll Fishery Biologist <br />1 GS- 7 Administrative Support <br />Data integration costs <br />Travel-Per Diem <br />Equipment and Supplies <br />Subtotal <br />Service Administrative Overhead (17.65%) <br />TOTAL <br /> <br />$ 4,000 <br />$13,000 <br />$ 2,000 <br />$ 5,000 <br />$ 5,000 <br />$ 6.000 <br />$ 35,000 <br />$ 6.200 <br />$41,200 <br /> <br />5 <br />
