Pacific island nations ratcheted up the fees they charge tuna fishing boats to enter their waters by a hefty 33 percent Friday as they accused foreign fleets of not doing enough to conserve stocks.
They also warned the United States, which operates under a separate tuna fishing agreement, that it also faced a substantial increase.
The eight countries that form the Parties to the Nauru Agreement (PNA) control waters covering more than half the world's skipjack tuna, the most commonly canned variety.
