SummaryTo address the two overarching questions in the Pacific Arena, we are focusing our research program around anadromous Pacific salmon (Oncorhynchus spp.), their physical and biological environments, and ecosystem management. We propose this for a number of reasons, including extensive tracking experience of investigators in the Pacific, biodiversity issues, ecosystem importance of salmon, economics of salmon fisheries and key management risks. Our research focuses on southern BC salmon, and primarily on those from or interacting with the Fraser River, as this river is Canada’s most productive salmon system, and home of a multi-sector, multi-species fishery. This system contains some extremely large populations of salmon (e.g. millions of adults), and some that are threatened with extinction. Our research also focuses on environmental transition zones: the Salish Sea, Continental Shelf. The freshwater–seawater transition zone is one of the most physiologically stressful locales for migrating salmonids. Transition zones are also areas of complex marine conditions and high predation.
