The importance of an ecosystem approach to the management of natural resources—including fisheries—has been widely recognized recently. However, discussions of ecosystem management usually do not provide much detail or emphasis on genetics. Here, we discuss the anadromous salmon (Oncorhynchusspp.) of the Pacific Northwest asan illustration of how important genetic considerations can be as part of an ecosystem approach to resource management. Pacific salmon have a complex genetic and population structure, referred to as a metapopulation structure, that is strongly influenced by the spatial arrangement of the rivers in which they spawn. The many factors that have contributed to the decline of salmon populations in the Pacific Northwest have affected salmon meta-populations as well. As a result, attempts to rehabilitate salmon will need to include a focuson metapopulations as well as on improving habitat and reducing fishing and other sources of mortality.
