<br />Squawfish spaWn in, Gunnison River,
<br />
<br />Identification of tiny fish'
<br />
<br />confinns breeding success
<br />
<br />Colorado State University laborato-
<br />ry'scientists have ,verified what field
<br />biologists: . had 'long: suspe~ted::
<br />Colorado squawfish, can 'spawn' sue: '
<br />cessfully in the, Gunnison River
<br />upstream of Redlands Diversion Dam.
<br />Scieritists at the university's Larval
<br />Fish Laboratory, determined that at '
<br />least five of some 2,000.1arval fish col"
<br />lected from the GunnisonRiver by the
<br />Colorado, Divisic;m'of, Wildlife were'
<br />endarigered Colorado squaw fish,
<br />Squawfish larvae had never before
<br />been found upstream oL the Redlands
<br />Diversion Dam. The discovery bodes
<br />well for the recently completed
<br />Redlands Fish, Ladder, which allows
<br />the fish toswirn around the diversion'
<br />dam to upstream spawning and feeding
<br />areas, biologists say.
<br />Division, biologist Rick Anderson
<br />said less than one-tenth of I percent of
<br />the water was sampled, indicating,
<br />there probably" are many young
<br />Coloradosquawfish in the Gunnison, '
<br />Still, the key is whether they can sur' ,
<br />vive to adulthood and reproduce. '
<br />"In the past, the big problem for the,
<br />fish has been the (Redlanc!s) diversion
<br />dam," Anderson',said."Now that the,
<br />fish ladder is complete, and we know

<br />-Lynn ,Bjork and Diane Miller verified
<br />that at least five of 2,000 fish larvae
<br />collected in the Gunnison - River last
<br />, year were Colorado squawfish. '
<br />
<br />Colorado squawfish are reproducing in
<br />the Gunnison, we can' be even more
<br />optimistic that the fish can be recov-
<br />ered through natural reproduction."
<br />Colorado squawfish once grew to
<br />more than 5' feet long and were 'com- '
<br />mori iJl the Colorado River Basin,
