One of the major important segment of seafood industry in the United States is that which processes fishes of the mackerel family including the various tuna, the Atlantic mackerel, the jack mackerel and the Spanish mackerel.
Mackerel are no less plentiful in Baltic, North Sea, German Ocean, and all along the Scandinavian coasts, though its appearance is always erratic, since it is migratory in its habits.
Tuna are torpedo-shaped fish torpedo to a pointed nose and a slender caudal peduncle (the portion near the tail).
The more important species tuna include the bluefin, the yellowfin, the skipjack, and the albacore.
All mackerel are slim, cylindrical fish with razor sharp teeth that feed on smaller fish and squid.
Mackerel are much smaller than tuna, but they are similar shaped.
They are prized for their stay meat and their fighting ability and are important commercial and game fish.
Mackerel is one of the prettiest fish there is and one of the tastiest, cheapest and still most plentiful.
Apart from that it is small in size, the color being a steel blue, striated with undulating bands of black, while the belly is of a lustrous white, reflecting a bright silvery sheen when first take from the water.
In general, mackerel is very high in calories and fat and high in cholesterol, potassium, phosphorus and vitamin D and B12.
