The Parties to the Nauru Agreement (PNA) controls the world’s largest sustainable tuna purse-seine fishery. PNA countries provide around 50% of the global supply of skipjack tuna, the most commonly canned tuna.

The PNA members are: Federated States of Micronesia, Kiribati, Marshall Islands, Nauru, Palau, Papua New Guinea, Solomon Islands and Tuvalu.

The PNA has two main practices for conserving its fish stocks:

  1. limiting the catch of all fishing vessels through the vessel day scheme, explained in more detail under Catch & harvest
  2. banning the use of fish-aggregating devices by purse-seine fishers for three months a year.
