Popis: The complex problems involved in managing Pacific salmon (Oncorhynchus spp.) are largely a consequence of the unusual life history features of these species. The strong homing instinct leads to the formation of discrete, locally-adapted spawning populations, each of which has the potential to evolve as an independent evolutionary unit. It is important, therefore, that the genetic consequences of different management policies be carefully evaluated. If current management goals (e.g., doubling the abundance of anadromous salmonids in the Columbia River basin through increased hatchery production and supplementation of natural populations) are realized, genetic issues will assume even greater importance in the future. To date, however, genetic concerns have not been adequately incorporated into the management process. We identify three genetic approaches, primarily based on easily obtained electrophoretic data, that can provide valuable information on which to base management decisions: (1) Using th...
