The entire Alaska salmon fishery is certified sustainable by the Marine Stewardship Council, so choosing this source for your seafood ensures a guilt-free, pleasurable meal. Fresh Alaska salmon is easiest to find during the peak of the commercial harvest ― mid-May to mid-September. Off- season, however, frozen Alaska salmon is a good choice. It's flash-frozen shortly after being caught, so it can be even fresher-tasting than a never-frozen counterpart that has languished during shipping.
Sources for flash-frozen Copper River and other Alaskan salmon: Copper River Seafoods (888/622-1197) and Taku Smokeries (800/582-5122).
