Bluefish is a kind of fish which occurs in the Atlantic Ocean, the Mediterranean, the Black Sea, the Indian Ocean and the Pacific. It is a pelagic fish, which means that it lives near the surface of the ocean. They can grow to a size of 150 centimetres (59 in) and reach a weight of 15 kilograms (33 lb). In the wild, they live to be about nine years old.
Bluefish are predators: they hunt other fish, in small groups. Bluefish are caught commercially, and there is a problem with overfishing.
Sometimes another species, Rock salmon or Coal fish is erroneously called Bluefish.
