Abstract : The project was initiated at the request of the Gila Trout Recovery Team. The project designed a “Genetic Broodstock Management Plan”, a document that provides step-by-step guidance for development of four captive broodstocks to capture the genetic diversity the four existing relict wild populations. Each captive broodstock should have effective population size (Ne) of ~ 80 and use brood fish from 2 source stocks from the relict populations. Procedures are designed to minimize the number of fish removed from each of these already small wild populations. Guidance is provided for sampling the wild stocks and culturing them to maturity. Procedures are described for a series of 2 X 2 diallele breeding designs to create the new broodstock, stepwise systematic reductions to equalize family contributions to the final broodstock, and methods to systematically advance each generation using a combination of wild origin and captive broodstock that is alternated each generation. A genetic monitoring program is described in some detail with program implementation recommendations. The resulting captive broodstocks will be used to establish new “wild” populations as directed in the Gila trout recovery plan (2001). These broodstocks are expected to support the restoration effort and speed the time when the Gila trout can be down-listed and then de-listing as an endangered species. Gila Trout – Genetic Broodstock Management Plan from this project was developed to apply specifically to the situation faced in the restoration of the Gila trout. However, the concepts and approaches developed here provide valuable guidance and insight for other restoration programs that incorporate captive culture as a component of the total recovery program. The concepts and procedures are also expected to be valuable for management programs charged with the simultaneous goals of managing depressed / depleted populations and preserving the genetic diversity of those populations.
