<br />set in the sites and checked daily for three to five days. After fyke net sampling was <br />~ concluded a "scare and snare" tactic with an electrofishing boat and trammel nets was <br />employed. An outboard powered aluminum Jon boat equipped with a 6000 watt <br /> <br />generator and Smith-Root Model 5.0 GPP was used for electrofishing. Between one <br />and three trammel nets were used to snare fish. A large net measuring 1.5 m wide x <br />45.7 m long with 15.2 cm walling x 2.5 cm mesh was used during each effort. <br />~ Additional nets when used were 1.22 m wide with three 7.6 m panels of different walling <br />and mesh sizes. These sizes were 20.3 cm walling x 2.5 cm mesh, 17.8 cm x 1.9 cm <br />and 15.2 cm x 1.3 cm. Electrofishing (scare) was conducted in the vicinity of the <br />~ trammel net and attempts were made to herd fish into the net (snare). <br />During fall 1999 and spring 2000 sampling, captured razorback sucker were <br />weighed, measured, tagged with a Passive Integrated Transponder (PIT) tag, and <br />released back into the sites. Mark-recapture population estimates for age-1 fish <br />stocked in 1999 were generated for each site following the first growing season. <br />~ Below average spring flows and summer drought conditions resulted in poor <br />water quality at each study site during summer 2000. Razorback sucker were not <br />caught at The Stirrup site during late summer sampling indicating a possible complete <br />~ loss of fish in the site. With declining water quality, continued survival of razorback <br />sucker in the Baeser Bend site became a concern. These razorback suckers were <br />~ captured, weighed, measured, PIT tagged and released into the river. Fish health such <br />as condition factor, and fin condition appeared to be better at Above Brennan than at <br />the other sites. Razorback sucker captured in Above Brennan were weighed, <br />~ measured, PIT tagged and released back into the site. <br />8 <br /> <br />
