Catch controls on bluefin tuna are being tightened globally due to the very low resource levels. Japan consumes 28,000 tons of the bluefin tuna caught in the Atlantic Ocean, and this amount will decrease by 8,800 tons due to the reduced catch quota implemented by the International Commission for the Conservation of Atlantic Tunas （ICCAT）. At the same time, however, the Japanese capacity for producing farmed tuna is expanding. Therefore, a drastic supply shortage and a rise in the price might not occur for the time being. In the long-term, the likelihood of the implementation of catch regulation on the bluefin tuna in the Pacific Ocean is great, which will mean that the catch amount of the wild species would decrease and the cost of farmed tuna production using wild juvenile would increase. If a 30％ catch reduction for bluefin tuna, which is equivalent to the case of the Pacific bigeye tuna, were to be implemented, the price of bluefin tuna would rise from the current 3,000 yen/kg to 3,099-3,279 yen/kg in the wholesale markets, based on an analysis of the demand function for the species. This implies that an economic potential would emergefor the reproductive farmed tuna technology in the near future.
