<br /> <br />1 <br /> <br /> <br />~~' <br /> <br /> <br />Current Status and Research Efforts: The bonytail was one of the most <br />abundant fish present in the lower Colorado in the 1930s and is now <br />extirpated from this river reach. Along-term habitat is present in this <br />subunit at the High Levee pond on Cibola National Wildlife Refuge. This <br />facility is currently the focus of a five year investigation (Mueller et al. <br />2002). The data collected will be used to manage this site and other long- <br />term habitats as they are developed in the LCRMP management area. <br />Applicable Recovery Goals and Management Strategies: <br />Recovery Goal: Create and maintain a genetic refugia and/or self- <br />sustaining population while moving toward recovery. (See Lake <br />Mohave Subunit and Appendix I for downlisting and delisting <br />criteria). <br /> Management Strategies: These Recovery Goals will be met <br /> through the use of Strategy 1: Augmentation and Strategy 2: <br /> Isolated Habitats. <br />' Colorado Pikeminnow <br /> Current Status and Recovery Efforts: Wild Colorado pikeminnow are <br /> extirpated from the lower basin. This species occurred in large numbers <br /> in the lower river prior to its development for power generation and the <br /> introduction of nonnative fishes (Mueller and Marsh 2003). Restoration of <br /> the Colorado pikeminnow to this reach and in the future can be <br /> accomplished; however, success depends upon addressing the concerns <br /> of LCRMP team members from Arizona and California. The following <br /> comments reflect those concerns and issues by these states on the <br />proposed restoration in this subunit (CDFG 2001). <br />' In Arizona, AGFD proposed 10(j) populations of Colorado pikeminnow for <br /> this subunit in the past. Approval of a repatriation effort would require the <br /> Department to complete an Arizona Game and Fish Commission <br />' approved 12-step process for developing and approving reestablishment <br /> proposals for nongame and endangered wildlife. In addition to biological, <br /> • feasibility, and financial issues, principal concerns with proposals to <br /> repatriate this species to the lower river would likely focus on effects to <br /> cities, communities, and affected interests along or served by the <br />1 _. <br />' ~ 30 <br /> <br />
