It is a gregarious fish that lives in large shoals of 15 to 50m. It inhabits both the coastline and even the shore and is the food for many predators.
They feed on plankton, small fish, crustaceans and eggs of other species. It is a species whose fishing is strictly regulated by the European Union. Its meat has an excellent flavour, although it is poorly preserved.
It is generally found in the Atlantic Ocean, from southern Africa to northern Europe, the Mediterranean Sea, the Bay of Biscay, the English Channel and the North Sea. Its natural habitat is warm waters with high salinity, forming large patches on the surface during its movements (due to large shoals).
This blue fish is caught mainly by purse seine gear.
