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.

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.
