Prof. Yoshihiro has been working on tuna for decades. He said that most of the tuna is a species consumed in Japan, mostly for sashimi. Bluefin tuna is regarded as the premier sushi fish. “Tuna is the sushi in a sushi restaurant. If you have good tuna, you have a reputation of being a proper restaurant.” Prof. Yoshihiro delivered several species of tuna that are consumed in Japan such as Atlantic Bluefin Tuna / Pacific Bluefin tuna, big eye tuna, yellowfin tuna, albacore, and skipjack.
He said that in terms of the colour of meat, each tuna species has different characteristics. Japan leads the world in tuna consumption. It consumes one third of the world’s tuna production and 95 percent of the world’s toro. The highest consumption of tuna in Japan is of the Pacific bluefin tuna type, its consumption can reach 98% of the fish captured in the North Pacific. The price of tuna per kilogram in Japan is 1400 JPY (Rp 182,000 / kg); while for the price of frozen bluefin tuna fish is 4000 JPY per kg (Rp 520.000 / kg). For yellowfin species the price is around 1200 JPY per kg (Rp 156.000 / kg). Data in 2012 shows that the consumption of tuna from big eye species increased by 40%.
Many kinds of tuna are caught using purse-seine nets, which are capable of encircling and catching entire schools of tuna. Japan, South Korea, Taiwan and other major tuna fishing nations began using GPS devices in 2007 to monitor the activities of tuna fishing boats in the central and western Pacific Ocean, an area rich in yellow-fin and bigeye tuna. Tuna fishing technology in Japan uses long line fishing equipment, rod fishing, purse seine, and troll line. In addition to capture fisheries, Japan also develops bluefin tuna cultivation (tuna sea ranching). Kinki University is a pioneer of tuna fish culture in Japan. Tuna is cultivated in western and southern waters of Japan because the water temperature conditions suitable for bluefin tuna are 20-25 degrees Celsius.
