spawning. Fish #1642, originally implanted near Rangely <br />in 1983, was monitored and recaptured near spawning areas <br />in the Yampa River in 1984. This fish, recaptured in the <br />White River in 1985 8 km (5.0 mi.) from its original <br />capture site, had migrated over 700 km (450 mi.). Fish <br />#04040, implanted just below Taylor Draw Dam in June, 1985 <br />apparently spawned at the Gray Canyon spawning site in the <br />Green River in July and returned to the White River by <br />September. While passage of Colorado squawfish over ~ <br />Taylor Draw Dam was not documented by radiotelemetry, it <br />is believed that squawfish will move over the dam and <br />eventually disappear from the river above. This <br />disappearance of squawfish above Taylor Draw Dam will <br />represent the loss of 16~ or one sixth of the Colorado <br />squawfish range currently documented for Colorado. <br />The congregation of Colorado squawfish below Taylor <br />Draw Dam in August 1985 probably represented a <br />post-spawning migration of fish returning from spawning or <br />those searching for "home ranges" for overwintering. The <br />increased incidence of Colorado squawfish including <br />hooking and discard of several specimens by anglers <br />resulted in the August 15 - October 31, 1985 fishing <br />closure in 365 m {400 yds.) of the White River immediately <br />below Taylor Draw Dam. Electrofishing conducted within <br />the closure indicated that the fish had dispersed <br />downstream by mid-September. <br />xvii <br />
