14 <br />Colorado squawfish catch <br />In June, two Colorado squawfish were caught and released on <br />the Green River by the same angler at RK 508.4, and two in August <br />at RK 535.1,- also by one angler. On the Colorado River, two <br />squawfish were caught in June by different anglers, one at RK <br />75.6 and one at RK 107.8. The squawfish caught near RK 75.6 was <br />estimated by the angler to be "24 inches" in length (610 mm). No <br />other lengths were reported. <br />Anglers also reported catching squawfish on non-survey days. <br />On the Green River two squawfish were reported caught in July by <br />an angler, one at RK 508.1 and one at RK 466.3. On the Colorado <br />River, one "squawfish" approximately "6 inches" was released at <br />RR 98.1 in May, and two "8 inch" fish at RK 107.8, and a "14 <br />inch" fish at RK 82 were reported released in June. The angler <br />identification of these fish is suspect. Due to their small size <br />they could easily have been roundtail chub which were <br />misidentified as Colorado squawfish. Most anglers stated that <br />they were aware of the endangered status of the listed species <br />and informational brochures disseminated by creel clerks were <br />well received. <br />The creel clerks reported recognizing many of the anglers <br />who returned to fish quite often. Only 11% of anglers on the <br />Green and 14% on the Colorado River were non-Utah residents. Of <br />non-residents, 88~ fishing the Green and 750 on the Colorado <br />River were from the state of Colorado. <br />
