This species is found mainly in the temperate waters of the Mediterranean Sea, in the Black Sea and in the North Atlantic Ocean where it is extremely common and they are observed in large sandbanks in the pelagic zone up to about 200 m. During the summer months it is common to see them near the coasts on the surface of the ocean, while in the winter they migrate to deeper waters and further south, in search of warmer temperatures.

In terms of diet, it should be noted that the young specimens are omnivorous and eat organic debris and debris found on the coasts inhabited by humans. Then they become predators and feed on crustaceans, mollusks, sardines, and herring.

The spawning of the mackerel takes place during the night and not once, but eight or ten times. They leave between two hundred thousand and four hundred thousand eggs of 1 millimeter, which fall slowly until they reach the bottom where they open six days later. After the laying, the adult mackerels are dispersed over the sea surface in search of food to replace the lost energy, attacking, sometimes the banks of sardines and anchovies.

Economic importance

The Mackerel has a huge commercial importance for many Atlantic fisheries, which catch it with purse seines, trawls, gill nets and trammel nets. Its optimal fishing season occurs between February and May, while its global annual catch is usually above 1.5 million tons. The United Kingdom and Norway provide the largest amount of Atlantic mackerel, with annual catches reaching more than 166,000 tons and 160,000 tons respectively.

Despite its commercial condition, in 2011 the IUCN estimated that mackerel is in a state of least concern due to its abundance and wide range. However, the same organization has recommended a careful monitoring of the population of this species, especially since the effects of climate change may affect them. In the North-East Atlantic, several countries impose minimum landing sizes. In the European Union, this size is 18 cm, Ukraine 15 cm, Turkey 20 cm and Romania 23 cm.
