In fact, tuna can maintain the temperature of their muscles at 5–20 °C (9–36 °F) above the temperature of surrounding water. [31] Overall, tuna do not have a set body temperature point; rather it maintains its T B within a narrow range, with variations of only 4–5 °C (7–9 °F) over time and from individual to individual.

Japan is both the biggest consumer and the leader in tuna farming research. [17] [18] Kinki University of Japan first successfully farmed already-hatched bluefin tuna in 1979. In 2002, they succeeded in breeding them, and in 2007, the process was repeated for a third generation. [19] [20] [21] This farm-raised tuna is now known as Kindai tuna ...
