Mackerel is a common name applied to several species of fish. Many Americans might be familiar with the largest species of mackerel, called the king mackerel. Mackerel are prized for their oily meat, which is very high in omega-3 fats. Omega-3 fats are a type of polyunsaturated fat that offers a variety of health benefits.

There are many species of mackerel fish. The jack mackerel is a common type of fish found in the Pacific coastal waters. It is also called the blue jack mackerel, Californian jack mackerel, Pacific jack mackerel or saurel fish. Because it is a fattier fish, the Pacific jack mackerel offers nearly as much omega-3 fats per serving as salmon but is less expensive.
A 3-oz. cooked portion of Pacific jack mackerel provides 171 calories, 9 g of fat and 2 g of saturated fat. This modest serving size provides 1,759 mg of omega-3 fats. It is nearly as rich in omega-3 fats as Chinook salmon, which provides 1,822 mg per 3-oz. serving. Canned jack mackerel is the highest in omega-3 fats of all mackerel fish. One ounce of canned jack mackerel, drained, solids only, provides 385 mg of omega-3 fats.
Eicosapentaenoic acid, or EPA, is the type of omega-3 fatty acid found in marine foods, such as fatty fish. Omega-3 fats benefit the heart of both healthy as well as those at high risk of—or who have—heart disease, according to the American Heart Association. It is true that all fish contain some omega-3 fatty acids, but varieties such as jack mackerel are particularly rich sources. Per the American Heart Association, you should consume at least two 3.5-oz servings of fish, especially fatty fish, weekly.
Flavor and Use
Pacific jack mackerel has a flavor similar to canned sardines, and it is canned in the same manner as salmon and tuna. Pacific jack mackerel can be used in place of salmon or tuna in recipes. Tuna, particularly albacore tuna, is very high in methyl mercury. Jack mackerel is lower in mercury because it is a smaller fish and lower on the food chain, thus, it is safer to consume, especially for pregnant women and women of childbearing age.
According to the Heritage Recipes website, canned jack mackerel works well for making "mackerel cakes," which are like crab cakes. According to the author who obtained this recipe from her mother-in-law, canned mackerel was used in place of canned salmon as it was much less expensive. The recipe calls for a 15-oz. can of jack mackerel, one egg, 1/2 tsp. salt, stone ground cornmeal and 3/4-cup to 1 cup of oil for frying. The recipe makes seven individual-sized cakes and can be served with ketchup or barbecue sauce. One cake provides roughly 700 mg of omega-3 fats.
