Mackerel are swift, streamlined food and sport fish found in temperate and tropical seas, belonging to the Scombridae family. They are characterized by a torpedo shape, a slender tail base, and finlets behind their dorsal and anal fins. Mackerel are carnivorous, feeding on plankton, crustaceans, mollusks, fish eggs, and small fish. They typically form schools and inhabit the upper layers of the ocean, descending to deeper waters in winter and spawning along coastlines in spring and early summer.

The common mackerel (Scomber scombrus) is an abundant species in the Atlantic Ocean, averaging about 12 inches in length. It is blue-green above and silver-white below, with wavy, dark lines on its upper sides. The Pacific mackerel (Scomber japonicus) closely resembles the Atlantic common mackerel and is an important food fish on the Pacific coast of North America.12

Other related fish include frigate mackerels (Auxis) and Spanish mackerels (Scomberomorus), which are known for their quality flesh and are popular game fish. It is important to note that "mackerel shark" refers to a type of shark and is not a fish in the same family as the common mackerel.134
