Woodside section. Red shiners were captured more frequently in the seine than any other <br />species, but there was no clear trend in their catch rates from one year to the next. <br />Twenty-one Colorado pikeminnow have been captured by biologists in the Price River <br />from 1995 through 1998 (Table 10). This number includes 19 captured from 1996 through 1997 <br />during this study, one fish captured by BIO/WEST, Inc., in 1995 (Masslich and Holden 1995), <br />and one collected by the Utah Division of Wildlife Resources in 1998 while working on a related <br />project (unpublished data). One of these fish was captured twice in the Price River in 1997. <br />Another individual was tagged in the Green River 10 miles above the confluence with the Price <br />River in 1996 and recaptured in the Price River at river mile 24.5 in 1997. One Colorado <br />pikeminnow was captured at river mile 32.4 in the Price River in 1996 was recaptured in the <br />Green River in 1997 approximately 23 miles above the confluence with the Price River during <br />sampling conducted for an unrelated project (Tom Chart, Utah Division of Wildlife Resources, <br />unpublished data). Positive identification was made for seven Colorado pikeminnow that <br />avoided capture. Electrofishing produced all but four of the captured and observed Colorado <br />pikeminnow. Three Colorado pikeminnow were captured in trammel nets, and one was captured <br />by electrofishing and recaptured in a hoop net. <br />Anglers reported the capture of two Colorado pikeminnow in the Price River in 1997 <br />(Todd Davis, Wellington, Utah, personal communication) and one in 1998 (Bob Barney, <br />Wellington, Utah, personal communication). All three of these fish were caught in a pool below <br />Farnham Diversion (located at river mile 88.5). A photograph was taken of the fish caught in <br />1998, so this catch was verified as a Colorado pikeminnow. The fish caught in 1997 were not <br />photographed, so they were not positively identified. However, the angler claimed that he had <br />caught externally-tagged fish several years ago near Grand Junction, Colorado. He said that <br />when he reported the tag numbers to the U.S. Fish and Wildlife Service, he was told that the <br />tagged fish were Colorado squawfish (another common name for the Colorado pikeminnow). <br />Therefore, he felt confident in his ability to identify this species, and his verbal description of the <br />fish he caught in the Price River accurately described Colorado pikeminnow. <br />Juvenile and adult Colorado pikeminnow were captured in the lower Price River. The <br />size range of these fish was fairly similar to that of Colorado pikeminnow caught in the lower <br />Green River in 1996 and 1997, with the exception of a lack of very large individuals (Figure 24). <br />Most of the Colorado pikeminnow in the Price River were captured or observed near the bank in <br />runs that looked similar to areas where no Colorado pikeminnow were captured. Colorado <br />pikeminnow captured in the Price River ranged from 159 mm to 594 mm total length (Table 10). <br />These fish included one ripe male captured in a run located at river mile 10.5. Nineteen of the <br />twenty-one captured Colorado pikeminnow and all of the observed Colorado pikeminnow were <br />found in the lower 44.7 miles of the Price River. One Colorado pikeminnow was captured in the <br />pool located at river mile 88.5, and one was caught in a run located at river mile 83.5. <br />Radios were implanted in seven Colorado pikeminnow (Table 11). Two fish were radio <br />tagged but never relocated. Two other radio-tagged fish were located in the Price River every <br />time radio contact was made. One of these fish was tagged upstream from Woodside, Utah in <br />October 1996 and began moving downstream almost immediately. Within I 1 days this fish had <br />moved 19.8 miles downstream. This fish spent at least three hours moving within a pool at the <br />base of a rapid just before nightfall on October 12, 1996. By morning, it had left the pool and <br />was relocated 2.3 miles further downstream. In the spring of 1997, this fish was relocated in the <br />Price River on three occasions. No effort was made to locate this fish during the winter, so it is <br />11 <br />
