The Atlantic Mackerel is a pelagic fish of the mackerel family. It inhabits most coastal waters along the northern United States, the European Atlantic coast, the Mediterranean and Black Seas as well as the north-west Baltic. Adult specimens can reach some 50cm in length and weigh up to 1kg. Mackerel are nomadic fish and live in large schools. They feed mainly on small crustaceans, plankton, snails, and small fish. Aside from being a popular gamefish, the Atlantic Mackerel is an important economic driver of many national fishing industries, thanks to its high yield and long history of commercialization. It is prized for its taste and high concentrations of Omega-3 fatty acids and vitamin B12.
