International negotiations on the management of Pacific bluefin tuna have resulted in an agreement to increase catches of larger fish as the population continues to recover after years of strict conservation measures. Participating countries and territories agreed to raise the catch quota for Pacific bluefin tuna weighing 30 kilograms or more in the western and central Pacific by 25 percent. Under the agreement, the permitted catch for larger fish is expected to rise from 11,869 to 14,836 tons. At the same time, the quota for bluefin weighing less than 30 kilograms will be reduced by 6 percent, from 5,125 to 4,823 tons. The approach is designed to allow greater catches of mature fish while maintaining stronger protection for younger tuna, which are important for the future reproduction of the population.
The agreement is particularly significant for Japan, which had pushed for an expansion of the quota. Earlier negotiations in Nagasaki ended without a deal after Mexico opposed the Japanese proposal and sought changes concerning fishing in the eastern Pacific. Further discussions eventually produced a compromise. The decision follows years of international restrictions introduced after Pacific bluefin stocks fell to critically low levels because of heavy fishing pressure. Conservation measures subsequently contributed to a substantial recovery of the population, allowing regulators to gradually reconsider catch limits while continuing to monitor the sustainability of the stock.
The larger quota could eventually affect the Japanese market, where bluefin tuna is highly valued for sushi and sashimi. Greater supply could potentially ease prices for some cuts, including the prized fatty portions known as chutoro and otoro, although the actual effect will depend on catches, demand and how national quotas are distributed. The agreement does not represent a return to unrestricted fishing. Instead, the combination of a higher quota for mature tuna and a lower limit for younger fish reflects an attempt to benefit from the stock’s recovery without jeopardizing the progress achieved through years of conservation.
