Wild Alaskan king salmon is known for its rich flavor, oily texture, fatty acid content, and limited supply. Also known as chinook salmon, this is the most coveted of all salmon species. With some growing to be over 100lbs, king salmon spend their entire adult lives building up their muscle and fat content to make the 2,000 mile journey upriver to spawn. Fishermen strategically place themselves to harvest the salmon at the beginning of their run before the muscle and fat has wasted away. This is also why the king salmon has the highest levels of omega-3 fatty acids.
Young salmon feed on plankton and insects. When adult salmon migrate to the ocean in their second year, their diet expands to include herring, pilchard, sand lance, squid, and crustaceans. This varied diet can also create subtle variations in taste and nutritional information. Most king salmon is bright red color. Ivory king salmon, a subspecies of king salmon, is coveted for its creamy, white-colored flesh. Otherwise, the ivory king has the same rich texture and nutritional content as other king salmon.
There is a set limit of how many king salmon can be caught in southeast Alaska, where harvests are controlled by a maritime treaty between the U.S. Still, with declining numbers, there are tough restrictions in effect all over Alaska. This year, outside of treaty areas, the harvest of King Salmon was under 100,000 fish. As such, it’s no surprise that this salmon is often twice as expensive as other salmon. The average king salmon is 36 inches long and weighs about 30 lbs.
