Mackerel (Scomber scombrus), also chicory, is a pelagic species that forms flocks. Mackerel belongs to the family Scobrides, but other members of the family are called mackerel. It is found in the North Atlantic Ocean and the Mediterranean and is a related species with Scomber japonicus. It is a sought-after edible fish, like the rest of the fish in this family. Mackerel needs attention, because it is a quite greasy fish. However, it enriches the body with vitamin A, calcium, magnesium, phosphorus and the antioxidant selenium. It also contains antioxidants Ω3 fatty acids that have great anti-inflammatory and antithrombotic properties. Ω3 also inhibit the occurrence of arrhythmias and atherosclerosis and play an important role in cellular processes associated with lipid metabolism.

Mackerel has a maximum length of 60 cm and a maximum recorded weight of 3.4 kg. Their usual length is 30 centimeters. Mackerel can live up to 17 years. One of its features is the black light wavy strips on the blue-green back that are almost perpendicular to the rest of the body. The belly is silver-white. The shape of its body is such that makes it to swim fast. It has two dorsal fins that are well spaced, which gather in a cavity when the fish swims to reduce the hydrodynamic resistance.  It has small scales, which do not stand out.
