Alaskan fisheries in Southeast Alaska (SEAK) intercept salmon returning to British Columbia (BC) rivers. Given the current depressed status of many BC wild salmon populations, and in the context of changing marine and freshwater environments due to climate change there is growing concern that as Canadian salmon abundance declines, and Canada closes or restricts its fisheries, Alaskan interceptions are having an increasing impact on Canadian salmon and steelhead populations.

This report series describes significant Alaskan exploitation on many BC populations, such as Area 3 (Nass), 4 (Skeena), and 5 (coastal streams south of the Skeena), sockeye, coho, chum and pink salmon, central coast salmon populations of all species, Fraser River sockeye and chinook from Vancouver Island, Strait of Georgia, and some Fraser River populations. Importantly, these impacts continue despite declines in abundance of many species in BC. Additionally, the commercial catch of Canadian-bound salmon in most recent years is higher in Alaska than it is in Canada.

The report provides a ‘State of Knowledge’ of SSEAK interceptions of BC salmon and steelhead that compiles and summarizes historical and recent information. Information on SSEAK catch were obtained through discussions with staff from Department of Oceans and Fisheries (DFO), Alaska Department of Fisheries and Game (ADF&G), and LGL Limited, and other agencies, and many additional resources were found online through the Pacific Salmon Commission Technical Committee websites, the Pacific Salmon Foundation Pacific Salmon Explorer, LGL Limited, and published literature and reports. Products of this work include the following technical summary, 100+ page data report, and R-code for figures and data summaries.
