COSEWIC released it most recent wildlife Species Assessment today. The assessment covers south coast Chinook including Fraser River, Thompson River, Vancouver Island and Southern Mainland populations.
Eight populations of Chinook were listed as endangered, four populations were listed as threatened, one population was listed as special concern, two as data deficient and one as not at risk.
From the COSEWIC press release:
Along with other species, COSEWIC also examined the status of Chinook Salmon, the king of the Pacific Coast salmon species. Mainly a migratory species, these large-bodied fish were historically abundant. Chinook Salmon are important culturally and as a food source for diverse groups of West Coast people, and also provide food for a diversity of wildlife species. The committee found 13 populations to be declining, with 8 assessed as Endangered, 4 as Threatened and one as Special Concern. Only the large population that lives in the Thompson River is stable.
“Many of these populations are in trouble”, stated John Neilson, Co-chair of the Marine Fishes subcommittee. “This may impact many species, including Endangered Southern Resident Killer Whale, which rely on Chinook Salmon for food.”

Desperate efforts to save the whales – and the Chinook salmon on which they depend – risk fishing communities losing a way of life.

Days before the start of the summer fishing season, when guides and outfitters on Canada’s west coast gamble their financial prospects for the year, fishing lodge owner Ryan Chamberland received devastating news.
The coastal waters of Vancouver Island, which he and four generations of his family had fished for salmon, would be out of bounds. The unexpected closure was part of a desperate effort by the Canadian government to save an endangered population of killer whales.
That same summer, Tahlequah, one of the threatened whales, nudged the lifeless body of her newborn calf for 17 days of mourning. Shortly after, the once-playful Scarlet, a three-year-old female orca, succumbed to a bacterial infection as scientists from the Canadian and US governments worked desperately to save her.
The unfolding tragedy of the southern resident killer whales – and the government response – has exposed a complex ecosystem in crisis. Chinook salmon, the whale’s main prey, are also disappearing. In an area heavily reliant on tourism and fishing, an impending collapse of the two species has led to feuding over how to stave off an ecological disaster.
