maintained in the same manner. If the hypothesis is accurate, inbreeding and outbreeding of RBS <br />in the hatchery environment at Dexter NFHTC will not be an issue. Disposition of research fish <br />will follow recommendations noted in the "Guidelines for Use of Fishes in Field Research" <br />(ASIWAFS/AIFRB, 1988). <br />Genetic Broodstock Management Objectives <br />(many tasks and management actions may be identical to address different objectives) <br />1) Develop a RBS broodstock program that conserves the genetic diversity of Lake Mohave RBS, <br />and produces offspring reflective of that diversity for recovery efforts. <br />Management Action: Establish a captive broodstock of at least 3,000 adults to represent <br />the Lake Mohave population, and characterize the genetic diversity present. <br />Management Action: Maintain genetic diversity extant in Lake Mohave RBS stocks. <br />Management Action: Ensure production fish contain acceptable genetic variation such <br />that the overall diversity of the augmented population is not reduced. <br />A. Task: Broodstocks from all facilities currently holding RBS will be inventoried <br />and compared using microsatellite loci, and broodstocks will be compared to <br />archived tissues and past genetic analysis of RBS stocks if available. This will <br />include Dexter NFHTC, Ouray NFH, Wahweap SFH, and Grand Valley Fish <br />Culture Facilities broodstocks. Target date: July 2003-July 2005 <br />31
