<br />Channel Catfish <br /> <br />Channel Catfish #40:5539 (CC553) <br /> <br />CC553 was captured by electrofishing near a rock outcropping, and among submerged <br />boulders at the head of a pool located at RM 97.1 on 25 JuL 1996. CC553 remained in <br />this general location and habitat until 13 August 1996 when it was located in a pool 1,7 <br />river miles downstream (Figures 15 and 16). Within 16 days this fish had returned to the <br />pool that contained submerged boulders where it had been captured (RM97.1). It <br />remained at this location until 24 September 1996 when it was located in a run 0.7 river <br />miles downstream. Within 15 days the fish had again moved back up to the submerged <br />boulders in the pooL By the end of the study on 24 October 1996, CC553 was located 3.6 <br />river miles downstream in a large deep pool at RM 93.6. During the recorded <br />movements, CC553 successfully navigated numerous riffles and runs often when the <br />mean daily discharge was lowest. <br /> <br />Channel Catfish #40:6732 (CC673) <br /> <br />CC673 was captured by electrofishing in the same location as CC553 (among submerged <br />boulders in the pool at RM 97, I), CC673 was always located near or within the deep <br />submerged boulder habitat except on 24 September 1996 when it was found in the run <br />0.70 river miles downstream (Figures 17 and 18). After this occasion, CC673 could not <br />be relocated by ground crews, however location by air in late October, but unconfirmed <br />by ground crews, indicated that CC673 had moved about 4,0 river miles downstream to a <br />large pool above the mouth of Juniper Canyon (RM 93.1). <br /> <br />Channel Catfish #40:6532 (CC653) <br /> <br />CC653 was captured by electrofishing at RM 79,5 on 23 JuL 1996. This fish had moved <br />upstream by 14 August 1996 to a run habitat located at RM 80.8. This run was a deep <br />slow moving run with an adjacent upstream pooL Throughout the course of this study, <br />CC653 was found in either the run or pool habitat. Although the fish apparently never <br />moved outside of these two adjoining habitat, it's location within these habitat was <br />variable (Figures 19 and 20), <br /> <br />Yarnpa River Radio Telemetry Repon <br />Miller Ecological Consultants, Inc, <br /> <br />Page 21 <br />January 23, 1997 <br />
