Genetic Stock Structure, Relative Productivity and Migration (Gene Flow) of White Sturgeon Among Bonneville, The Dalles, John Day and McNary Reservoirs in the Lower Mid-Columbia River Region

Abstract

This report presents the results of genetic monitoring of white sturgeon (Acipenser transmontanus) in the second of a ten year implementation period for the project. These results will be used to address long-term objectives for monitoring and conservation of populations among four upstream impoundments in the mid-Columbia River Basin (CRB): Bonneville, The Dalles, John Day, and McNary reservoirs. Our project objectives include evaluation of population differentiation and migration (gene flow) among reservoirs, and relatedness and effective population size within each reservoir. Further, long-term goals also include exploring parentage assignment between sampled young-of-the-year and mature adult individuals, and the eventual genetic characterization of individuals captured for broodstock in a proposed Yakama Nation sturgeon hatchery program
