A coalition of Canadian environmental groups, including the Raincoast Conservation Foundation and Watershed Watch Salmon Society, has lost their appeal against the Marine Stewardship Council's (MSC) decision to label Alaska's salmon fishery as sustainable. The groups argued that the certification overlooks the fishery's impact on salmon populations in British Columbia and endangered Southern Resident killer whales. Despite the groups' claims of unsustainable practices, an adjudicator upheld the MSC's decision, citing compliance with the Pacific Salmon Treaty and sufficient catch shares. The Canadian groups now call for consumer avoidance of Alaskan salmon and are working towards treaty reform to limit interception fisheries. Meanwhile, Alaska defends its fishing practices, asserting compliance with numerous policies and the most robust assessment program.
