Prevent extinction of bon)'tail chub in <br />the wild <br /> <br />Protect in Refugia <br /> <br />Establish and maintain refugia in <br />at least two locations <br /> <br />Evaluate genetics of captive <br />bonytail chub <br /> <br />Obtain wild bonytail chub <br /> <br />Verify taxonomic status of <br />individuals received at refugia <br /> <br />2. Reintroduce hatchery-reared bOn)1ail <br />chub into the wild <br /> <br />from the Upper Colorado River and is maintained at <br />Horsethie/. which serves as the backup refuge for Colorado <br />squawjish. Dexter NFH remains the primary Colorado <br />squawjish refuge facility. <br /> <br />A single experimental stocking program has been attempted at <br />Kenney Reservoir on the White River. The experimental <br />stoc/dng program stocked 86,601 Colorado squaw fish between <br />1988-1990 into Kenney Reservoir. Only 4 fish were captured <br />in 1991, and none were captured by 1992. No other <br />experimental or other reintroduction programs are currently <br />planned. <br /> <br />No progress has been made regarding this activity. No stocking <br />plan is being developed for Colorado squaw fish. <br /> <br />Reintroduction/augmentation programs have not been <br />conducted by the Recovery Program. <br /> <br />Bony tail chub are believed to be functionally extirpated in the <br />Upper Basin. <br /> <br />Initial refugia for the bony tail was located at Dexter NFH in <br />New Mexico. In 1990, a back-up refuge was started at <br />HorsethiefSIVA. <br /> <br />The genetic evaluation of captive bony tail chub is currently <br />being performed while addressing the taxonomic problems in <br />Colorado River Basin Gila species. The refugia populations <br />were sampled as part of this study. This evaluation will be <br />completed in 1997. <br /> <br />No additional wild bony tail have been captured and added to <br />refugia populations due to the absence of adult populations in <br />the Upper Basin. <br /> <br />Taxonomic status of bony/ail received at refugia have been <br />determined by appropriate personnel. All fish transferred to <br />refugia have been PIT-tagged with appropriate records kept of <br />their point of origin and other pertinent information. Non- <br />lethaltissue sampling techniques were developed as part of the <br />Gila taxonomy study. <br /> <br />39 <br />
