<br />Northern Pike <br /> <br />Northern Pike #40:5834 (NP583) <br /> <br />NP583 was captured by angling on 25 July 1996 at RM 95.1. The pool where this fish <br />was captured and most commonly occurred throughout the study was a small side pool <br />created for a water intake structure, The pool was greater than 5 feet deep in places and <br />had boulder and sand substrate. This pool was bordered by the river bank on one side and <br />a shallow riffle on all other sides. On two other occasions, NP583 was located in a <br />backwater habitat that occurred at the front end of a pool 0, I river miles downstream. On <br />another occasion NP583 was found in a backwater habitat that was located 0.4 river miles <br />upstream. NP583 was never located by ground crews more than 0.5 river miles from the <br />pool where it was captured (Figures 25 and 26). <br /> <br />NP583 was the only fish other than squawfish to participate in a 24-hour observation. <br />Although observations were only made sporadically, it is interesting to note that at 9:30 <br />p.m, on 24 Sep. 1996 the fish was located in the pool where it was originally captured (at <br />RM 95.1), but by 10:45 p.m. it had moved nearly 0,2 river miles upstream. By 11:00 <br />a.m, the next day, NP583 had returned to it's original location (Figure 27). <br /> <br />Northern Pike #40:5440 (NP544) <br /> <br />NP544 was captured by angling on 26 July 1996 at RM 78.5. By 12 Aug, 1996 this fish <br />had moved 0.3 river miles downstream to a backwater habitat at the front of a large pooL <br />The following day (13 Aug, 1996) NP544 was back in the pool where it was originally <br />captured. For the remainder of the study NP544 was located on each observation week in <br />this same pool usually inhabiting low velocity, deep water habitat (Figure 28 and 29), <br /> <br />Yampa River Radio Telemetry Report <br />Miller Ecological Consultants, tnc. <br /> <br />Page 32 <br />January 23, 1997 <br />
