After maturing at sea, Chinook Salmon on Canada's West Coast swim back to their natal streams to spawn. Twenty-eight populations of Chinook Salmon live in Southern British Columbia, each with different habitats and survival strategies. Chinook Salmon face many threats in both fresh and saltwater, including climate change and detrimental effects from hatchery fish. At the current meeting, COSEWIC considered the 12 populations of Chinook Salmon most impacted by hatcheries: four were designated Endangered, three Threatened, and one Special Concern, while one was deemed Not at Risk. Three remote populations were determined to be Data Deficient, and will require additional research before being re-assessed. Details here.
