Atlantic bluefin tuna (Thunnus thynnus) is a pelagic species distributed throughout the North Atlantic and the Mediterranean, from Brazil to northern Norway. Living between the surface and 500 to 1000 metres deep, it migrates great distances from the cold waters where it feeds to warmer regions where it breeds.  

In the Mediterranean, Atlantic bluefin tuna is fished by about twenty countries. Due to overfishing in the 1990 and 2000s, and concerns raised by environmental groups, fishers, businesses and the general public, its fishing is strictly supervised by the International Commission for the Conservation of Atlantic Tunas. A restoration plan was set up in 2007 for a period of 15 years, which defined approximately fifty measures of conservation, monitoring and control of fishing activities.
