In the spring of 2010, the Government of Canada invited PICES to participate in a Commission of Inquiry into the Decline of Sockeye Salmon in the Fraser River by considering how marine ecology may have affected their abundance. A major objective that was achieved in this report was to assemble, within an eight week period, as comprehensive a summary as was possible of what is known about Fraser River sockeye salmon (Oncorhynchus nerka) in the ocean. While much of this effort involved summarizing information published in data/technical reports and the primary literature, where necessary, original data have been re-examined and new analyses conducted to fulfill the terms of the Statement of Work. The compilation provides a background of knowledge against which to judge what can be known regarding the two major questions posed by the Cohen Commission to PICES:-Can the decline in Fraser River sockeye in 2009 be explained by the conditions the fish experienced in the marine environment?-Is there any evidence for declines in marine productivity or changes in Fraser River sockeye distribution that can be associated with the 15-year gradual decrease in Fraser River sockeye productivity?Issue/Article Nr
