0 <br />Junction were completed in July 1992 and are capable of holding young <br />razorback sucker. Fish transferred to grow-out ponds will be grown to the <br />recommended size before being released into the river. <br />Breeding strategies will be developed that will define the criteria for <br />10 <br />0 <br />crosses, thereby ensuring protection of genetic diversity. Crosses made <br />between broodstock to produce progeny must strictly follow the procedures and <br />protocol outlined in the breeding strategies developed by the Propagation <br />Coordinator (Appendix; Table 3) and sanctioned by the Propagation <br />Subcommittee. Attempts to collect additional wild adult razorback sucker from <br />the upper Colorado and Gunnison rivers should continue to supplement existing <br />captive broodstocks so that desirable population characteristics are <br />maintained. <br />Habitat Development/Enhancement <br />Stocking Sites <br />Criteria for stocking sites must be developed before razorback sucker are <br />C <br />L <br />stocked. The most important concern is whether suitable habitat is available <br />for all life stages. There is little justification for releasing hatchery <br />fish in degraded or otherwise unsuitable habitats. Sites selected for initial <br />stocking of adult razorback sucker in the upper Colorado River and major <br />tributaries could be determined from 1) historic-use areas, either presently <br />or recently occupied by adult razorback sucker, and 2) criteria and <br />recommendations developed from past (Valdez et al. 1987) and future habitat <br />suitability studies of the upper Colorado and Gunnison rivers. CDOW will <br />begin a habitat study in 1992. Recommendations about where suitable habitat <br />may occur for sustaining adult razorback sucker or where habitat might be <br />19 <br />ID
