Higher Pacific Salmon Abundance in Canadian Arctic Linked to Warming Seas
A new study by researchers at Fisheries and Oceans Canada and the University of Alaska Fairbanks links higher Pacific salmon abundance in the Canadian Arctic to warming ocean temperatures.
The study, published June 5 in the journal Global Change Biology, found that a two-part mechanism was tied to the presence of salmon in the Canadian Arctic.
Warm late spring conditions in the Chukchi Sea, northwest of Alaska, drew salmon into the Arctic. When those conditions persisted in the summertime Beaufort Sea, northeast of Alaska, salmon could continue to Canada, researchers said.
Canadian and Alaskan scientists, working together with communities in the western Canadian Arctic, connected the salmon booms experienced by subsistence fishermen in recent years with a sequence of warm,...
