Chum salmon caught in Washington’s Puget Sound and coastal rivers is a "Good Alternative." It's unknown if the main chum salmon populations are healthy, but overfishing is not likely occurring. However, salmon from endangered or threatened Chinook or chum populations are also caught. Moderately effective management is challenged by the presence of depleted populations and other complex factors. Many salmon runs in Alaska and on the U.S. West Coast are augmented by large numbers of hatchery salmon, which could reduce the ability of wild populations to survive. Some sources of chum salmon are certified sustainable to the standard of the Marine Stewardship Council.
