Fresh Wild Whole King Salmon (also known as Chinook, scientific name Oncorhynchus tshawytscha) is sold whole by the pound at Costco. King salmon is the largest of the five Pacific salmon species, prized for its exceptionally high oil content, vibrant red flesh, firm texture, and rich, buttery flavor. Harvested from wild Alaska waters, it is the premium choice among salmon varieties for its superior taste and nutritional profile.

Wild king salmon delivers an outstanding concentration of long-chain omega-3 fatty acids (DHA and EPA), which support heart health, brain function, and healthy development. Each 3 oz serving provides approximately 22g of protein and 1,476mg of omega-3s, along with 100% of the daily value for Vitamin B-12 and zero carbohydrates. The fat content is notably higher than other salmon species, giving the flesh its signature buttery richness and making it ideal for a wide range of cooking methods.

The Alaska king salmon fishery is certified under both the Marine Stewardship Council (MSC) and Alaska Responsible Fisheries Management (RFM) standards, ensuring it is sustainably harvested. Fishermen use gillnetting and trolling methods along Alaska's coastline. Fresh whole king salmon is available seasonally and is best prepared by baking, grilling, broiling, poaching, sautéing, roasting, smoking, or serving as sushi or sashimi. The whole fish form is ideal for those who want to fabricate their own fillets or roast the fish intact.
