Participating countries and regions of the Pacific bluefin tuna regional fisheries management organization agreed to expand the catch quota for large tuna today [4].
The agreement resolves a diplomatic deadlock that threatened the management of the species and limited the market supply of large bluefin tuna.
The decision followed a period of tension that peaked during a meeting in Nagasaki City, Japan, in July 2026 [3]. During those discussions, Mexico opposed the expansion of the quota, leading to an unusual stalemate [3]. This lack of consensus meant that the group failed to reach an agreement on the increase during the July sessions [3].
Efforts to break the deadlock continued throughout the following weeks. Negotiations with Mexico were scheduled for July 30, 2026 [2], as officials sought a compromise to satisfy both sustainability goals and market demand [1]. Earlier proposals had included a 25% increase to the tuna catch quota, though that specific figure was not accepted [1].
The resolution came during an online video conference held on the morning of Aug. 18, 2026 [4]. Mexico reversed its previous opposition, allowing the participating nations to secure a deal to expand the fishing limits [4].
Officials said the reversal was intended to better manage the Pacific bluefin tuna resource while addressing the economic needs of the fishing industry. The agreement marks a shift from the impasse seen last month, ensuring that the quota for the species can be adjusted to reflect current resource levels and commercial requirements.
“Mexico reversed its previous opposition, allowing the participating nations to secure a deal.”
The reversal by Mexico removes a primary geopolitical hurdle in the management of one of the world's most valuable fish species. By moving past the July stalemate, the RFMO can now align catch limits with biological data and market demand, balancing the economic interests of fishing nations with the long-term sustainability of the Pacific bluefin tuna population.
