Sockeye salmon returns plunge in BC, as climate change mainly to blame | Vancouver Sun
In one of the most dramatic shifts, the federal department has adjusted the number of returning Fraser River sockeye expected this year to slightly more than 600,000, down from an earlier projection of nearly five million.
Twelve out of 13 Fraser River chinook populations have been recommended for protection under the Species at Risk Act, while coho returns in Alaska and Skeena River sockeye returns also prompted significant fisheries closures.
Willimont said his groups have identified just 16 chinook in five Fraser River tributaries above the slide.
Just under 5,000 fish were counted in those tributaries in 2014 and those numbers were considered dire at that time, he said.
