(303) 291-7322 <br />NEWS RELEASE ' FOR IMMEDIATE RELEASE <br /> <br />.l.Jly 13, 1990 <br />Contact: Connie Young <br />(303) 291-7322 <br /> <br />HATCI-ERY FISH NOT QUID< FIX <br />FOR SQUAWFISH RECOVERY, BIOLOGISTS SAY <br /> <br />DENVER -- For biologists working to recover endangered fish, the recent <br />discovery of three adult hatchery-spawned Colorado squawfish, in the Col~rado <br />River answers only one of many complex questions involved in the species' <br /> <br />recovery. <br /> <br />Can hatchery-spawned Colorado squawfish survive to adulthood and sexual <br /> <br />maturity in the wild? Yes. <br />But how are hatchery-spawned Colorado squawfish different from those fish <br />spawned and hatched in the wild? To what extent should hatchery-spawned <br />, Colorado squawfish be stocked? And will the male fish found 'in the Colorado <br /> <br />, ' <br />River near Grand .l.Jnction succeed in finding females, locating suitable' <br />spawning habitat and fertilizing eggs? Those are some of ,the other questions <br /> <br />researchers still face. <br /> <br />Between 1982 and 1984 the U.S. Fish and Wildlife Service stocked about <br /> <br />75,000 Colorado sq.Jawfish from the National Fish Hatchery in Dexter, N.M., in <br />the Colorado and Gunnison rivers. The two-to-four-inch fisn were only ~ few <br />months old. Before being stocked, each fish was tagged with a small piece of <br />magnetized wire that could be detected electronically. <br /> <br />more <br />
