Japan is the main destination of Mediterranean bluefin tuna. As the catches are insufficient, a cultivation technique has been developed that consists of the capture by means of purse seine fleets, in which even small planes can be used. Later in the farms, located mostly in the Murcia region, fattening and greasing stages are carried out. To learn more about this topic, read the following article by F.

In Japan, the cycle of artificial reproduction of bluefin tuna has been completed. For the first time, this species has been bred in a specimen, although its application today still requires many more phases of development and study. An Australian company has developed the first artificial propagation plan for bluefin tuna, an endangered species. It is a very migratory species, in continuous displacement.

The normal cycle takes place in the month of June where from the Atlantic it goes to the Mediterranean Sea to spawn, to later return.

Record catch of bluefin tuna: although there are mid-twentieth century catches of 800 kg specimens, the largest bluefin tuna caught under the rules of the International Association of Sportfishing (IGFA) weighed 678.6 kg (1,496 pounds).
