More information
The wild fishery for Alaska Pollock, also known as Walleye Pollock, is the largest by volume in the United States and is also one of the largest in the world. Alaska Pollock is a different species than the Pollock found on the Atlantic coast, and it is the most common type of Pollock in U.S. markets. All Alaska Pollock is wild-caught in the northern Pacific Ocean. Pollock is primarily harvested by trawl vessels, which tow nets through the middle of the water column. Some vessels are known as catcher/processors because they are large enough to catch their own fish and then process and freeze them at sea. Other vessels deliver their catch to mother ships (at-sea processing vessels that do not catch their own fish) or to shore-side seafood processors. Alaska Pollock is a high protein, low fat fish that provides between 400 and 500 milligrams of heart healthy omega-3 fatty acids per 3 ounce cooked serving. The nutritional composition of processed seafood products made from Alaskan Pollock varies depending on the ingredients added to the product and the method of preparation. Breaded items have additional carbohydrates and calories and may have more saturated fat if they are fried or cooked in oil. Surimi products may have lower levels of protein and fat and higher levels of carbohydrates. All of these products contain omega-3 fatty acids although the levels may be lower. Specific nutrition information for various products is available on their nutrition labels.
