IATTC

The Inter-American Tropical Tuna Commission (IATTC) is the tuna RFMO for the eastern Pacific Ocean, established by a 1949 convention between the United States and Costa Rica and now governed by the 2003 Antigua Convention. It manages tropical tunas (yellowfin, skipjack, bigeye), bluefin, and associated species, setting purse-seine and longline capacity limits, FAD restrictions, and seasonal closures (the veda). The IATTC also runs the Agreement on the International Dolphin Conservation Program, which sets dolphin mortality limits and the dolphin-safe observer regime for the eastern Pacific tuna-dolphin fishery.
