Where do bluefin tuna live? Bluefin tuna live mainly in the North Atlantic pelagic ecosystem and its adjacent seas, especially in the Mediterranean Sea. Geographically, their population is distributed throughout the North Atlantic, from Ecuador to Norway and from the Black Sea to Mexico.
There are two independent populations or stocks of bluefin tuna: a lesser population in the western part of the Atlantic that spawns in the Gulf of Mexico, and a greater stock in the eastern part of the Atlantic, distributed in the East Atlantic, the Mediterranean and, in the past, the Black Sea, with the Mediterranean Sea as the spawning area.
