The main objective of the Inter-American Tropical Tuna Commission (IATTC) is to ensure the long-term conservation and sustainable exploitation of stocks regulated by the Convention in accordance with the relevant standards of international law.

It was established by the Convention for the Establishment of an Inter-American Tropical Tuna Commission, signed by the United States of America and Costa Rica in Washington on 31 May 1949 and entered into force on 3 March 1950.

In 2003, the Convention for the Strengthening of the Inter-American Tropical Tuna Commission, known as the "Antigua Convention", which was negotiated to reinforce and replace the 1949 Convention, was opened for signature by the Parties. The Antigua Convention entered into force on August 2010.

Since 1992, IATTC has been developing an International Dolphin Conservation Program aimed at the progressive reduction of incidental mortality of dolphins in the purse-seine tuna fishery. This program was established by the Agreement on the International Dolphin Conservation Program (IDCP), a legally binding multilateral agreement, which entered into force in February 1999.



  1. Commission, it is composed by national sections, encompassing one to four members, nominated by the respective governments of the Contracting Parties. It meets at least once a year and is responsible for pursuing the objectives of the Convention.
  2. Advisory Committees, each Contracting Party shall have the right to establish an advisory committee for its section. The advisory committees are invited to attend the non-executive sessions of the Commission.
  3. Permanent Working Group on Compliance, the Compliance Working Group is composed of representatives of the Contracting Parties (CP) of the IATTC with the following functions:
  • to identify non-Contracting Party (NCP) vessels operating in the area;
  • to monitor CPs compliance with conservation and management measures by both the IATTC and the APICG;
  • propose the requirements for obtaining Cooperating Non-Contracting Party status;
  • analyse the information transmitted by the CPs and the reports produced by the APICG Secretariat;
  • propose criteria and draw up a list of vessels identified as being engaged in IUU (Illegal, Unregulated, Not Reported) fishing activities in the region.

With the entry into force of the Antigua Convention (27 August 2010), two new Committees were created:

  1. Committee for the Review of the Implementation of the measures adopted by the Commission, composed of representatives designated for that purpose by each member of the Commission, who may be accompanied by experts and advisors
  2. Scientific Advisory Committee, composed of a representative appointed by each member of the Commission, with appropriate qualifications or relevant experience in the area of competence of the Committee, who may be accompanied by experts or consultants.

 Eligibility conditions

  • Implementation of the relevant IMO vessel identification system, if required under Union law
  • The fishing vessel is not on a list of IUU vessels adopted by an RFMO and / or the Union under the IUU Regulation

Populations of tunas and related species.
 Species with special catch registration and control regimes

Since bigeye tuna is the main target species for "flag of convenience" vessels and considering that most of the catches are exported to the territory of Contracting Parties, especially to Japan, IATTC established a Statistical Documentary Program for Bigeye Tuna, like ICCAT and CTOI.


  • Reduction of accidental mortality of juvenile tunas
  • Reduction and mitigation of catches of non-target species, such as sharks, swordfish and sailboats, rays, goldfish and others
  • Reduction and mitigation of accidental catches of sea turtles and seabirds.

 Fishing gear(PT)

Surface longline.

Boarding of Observers

A minimum coverage of 5% must be ensured on vessels over 20 meters in length.
