The plan focuses primarily on genetic broodstock reserves and captive propagation of stocks from <br />the lower Colorado River basin in Lake Mohave, Arizona. However, a brief description of stocks <br />currently and historically held at other facilities is included. <br />The plan is guided by the RBS Recovery Plan (U. S. Fish and Wildlife Service 1998) and <br />RBS Recovery Goals (U. S. Fish and Wildlife Service 2002). The plan incorporates genetic <br />guidelines provided by the Recovery Implementation Program for Endangered Fish Species in the <br />Upper Colorado River Basin (U. S. Fish and Wildlife Service 1994), Genetics Management Plan <br />For The Endangered Fishes of the San Juan River (Crist and Ryden 2003), and the Conservation <br />Plan for the Colorado River Multi-Species Conservation Program (MSCP) (SAIC/Jones & Stokes <br />2001). Goals and objectives of the MSCP were developed based on conservation recommendations <br />presented in Biological Opinions for the lower Colorado River, primarily Lake Mohave (1994; <br />1997) and Lake Havasu (1993). <br />The RBS Recovery Goals geographically delineate the management efforts in the Colorado <br />River basin as two recovery units: the upper basin, including the Green River, upper Colorado <br />River, and San Juan River subbasins; and the lower basin, including the mainstem and its tributaries <br />from Glen Canyon Dam downstream to the international boundary with Mexico (Figure 1). The <br />following is a discussion of the current status of wild and captive stocks based on those geographic <br />distinctions, and relates broodstock development at Dexter NFHTC to upper and lower basin needs.
