This evaluation should determine the genetics of bony tail chub broodstock, those currently at Dexter National Fish Hatchery, and those taken from the wild. 113. Obtain wil d bonyta il chub. An intensive collection effort should be initiated to obtain additional wild bony tail chub from areas where they occur. A mechanism and protocol has been established for obtaining these individuals. Workers should be prepared to properly hold and transport captured bony tail chub to refugia. Proper protocol for the handling of individuals which maximizes survival should be developed and revised as necessary. Quarantine procedures at refugia must be enforced. Funds identified in the implementation schedule of this plan are considered to be sufficient to support initial collection efforts. However, if an insufficient number of wild fish are collected, additional funds may be needed for further collection efforts. 114. Verify taxonomic status of individuals received at refugia. After stabilization, the fish received at refugia must be inspected and their taxonomic status determined by qualified personnel. A photograph of the fish on a 1 cm (0.4 in.) grid will be taken and made available to interested persons. Each fish will be tagged and a record kept of its point of origin and other pertinent information. Nonlethal techniques (e.g., electrophoresis) should be developed that can type specimens using tissues such as fin, gill filaments, etc. 12. Protect populations of bony tail chub and their habitats. Actions must be taken to minimize threats and adverse impacts to bony tail chub and their habitats. A restriction on the stocking of warmwater nonnative fishes should be implemented since competition and predation are believed to be major threats to the survival of bony tail chub. Emphasis should be placed on developing cooperative agreements with State and Federal agencies and private groups to restrict uncontrolled stocking of nonnatives and to develop a coordinated program to protect and recover the bony tail chub. 121. Enforce established regulations to minimize threats. Existing regulations have been established to control habitat or streamflow alteration, taking and possession of endangered fish, and other human activities that may adversely affect the species or its habitat. As studies are completed, new information may indicate that additional regulations and/or strategies are necessary. 14
