Movement of Radio-Tagged, Adult Fish <br />Colorado squawfish <br />In 1986, six squawfish and two razorback suckers were radio-tagged in late <br />spring (Appendix). All were captured from within the 15-mile-reach, most <br />from or near a gravel-pit pond connected to the river at RM 174.4. Contact <br />was lost with one squawfish and one razorback sucker one week after release. <br />Two squawfish moved into the Gunnison River during June (Fig. 2). One of <br />these (A) later died and the other (F) returned to the area of release in <br />late July, where it remained until at least May of the following year. This <br />fish (F) was next located near the Walker Wildlife Area (WWA, RM 163.6) of <br />the downstream 18-mile reach on June 25, but returned to the original <br />release location in the 15-mile reach by July 9 where it remained through <br />mid August when contact was lost (presumably tag failure). Another <br />squawfish (D) stayed near the point of release until at least mid June of <br />the following year. On July 7 it was located 45 miles downstream near the <br />Utah border. By July 21, it had returned to the original release location <br />in the 15-mile reach. Another squawfish (J) moved upstream in mid July, <br />over the Grand Valley Diversion dam, to the plunge pool of the Price Stub <br />Dam. It remained there until the end of September when it returned <br />downstream. Between early October and the end of March, the fish (J) <br />remained near its initial point of release. In July, it made two brief <br />forays to the base of the Redlands Diversion Dam on the Gunnison River, each <br />time returning to the 15-mile reach after a day or two. In late July 1987, <br />it returned to the plunge pool of the Price Stub Dam and remained there <br />until September, when it returned to the point of release. <br />7
