. They are characterized by deeply forked tails that narrow greatly where they join the body; small finlets behind both the dorsal and the anal fins; and sleek, streamlined bodies with smooth, almost scaleless skins having an iridescent sheen. All members of the mackerel family are superb, swift swimmers. The firm, oily texture of their powerful muscles and their generally large size make them of great commercial importance as food fish. They travel in schools, feeding on other fish (chiefly herringherring,

) and on squid, and migrate between deep and shallow waters. The smaller species rely on the constant rush of water through their gills for sufficient oxygen and will suffocate if motionless. The largest of the family, the enormous (up to 3-4 ton/680 kg) tunas, are among the few warm-blooded fishes, due to the constant operation of their huge banks of muscles. Of the smaller members of the family, the Atlantic, or common, mackerel, Scomber scombrus, found in colder waters off North America and Europe, is one of the smallest (1 1-2 lb/0.675 kg average). Despite its size, the annual catch is 1 million tons, which is marketed fresh, salted, and canned. Intermediate between the Atlantic mackerel and the bonitos (see tunatuna

) are the frigate mackerels, or frigate tunas, found in warm seas. Spotted species found off the Florida and Gulf coasts include the Spanish, painted (or cero), and Serra mackerels, averaging 10 to 15 lb (4.5–6.7 kg). Other species are the king mackerel, also called kingfish (up to 60 lb/27 kg); the chub mackerel, similar to the Atlantic mackerel; and the cosmopolitan and more solitary wahoo, or peto. The snake mackerels, including the escolars and oilfish (some species of which are sometimes marketed as white tuna or codfish), belong to the family Gempylidae. Mackerels and snake mackerels are classified in the phylum ChordataChordata

Mackerel

 

(Scomber scombrus), also Atlantic mackerel, a fish of the family Scombridae of the order Perciformes. The body, which is spindle-shaped and covered with small scales, is about 60 cm long and weighs about 1.6 kg. The color above is bluish green with several black curved stripes.

The mackerel is found along the European coast from the Barents and White seas to the Canary Islands. It is also present in the Baltic (up to the Gulf of Finland), North, Mediterranean, and Black seas, as well as in the Sea of Marmara. Along the eastern coast of North America the fish is found from Labrador to the Carolinas. A thermophile pelagic schooling fish, the mackerel winters at depths of 150–250 m. In the spring it migrates to the coasts for reproduction. After spawning, which occurs in the summer at shallow depths, the fish migrates along the coast in search of food. Sexual maturity is reached in the second to fourth year. Fecundity is about 500,000 roe. The mackerel is a commercially valuable fish.

Related species are the chub mackerel (S. japonicus) and the slimy mackerel (S. australasicus). The chub mackerel is commonly found off the western and eastern coasts of the Pacific (including the Sea of Japan), off southern Africa, and off the western and eastern coasts of the Atlantic (including the Mediterranean and Black seas). The slimy mackerel occurs off South Australia and New Zealand.
