 Coverage Area CTOI


The Agreement for the Establishment of the IOTC, concluded under Article XIV of the FAO Constitution, was adopted in November 1993 and entered into force in March 1996.

The CTOI Organization has an area of ??competence covering FAO statistical areas 51 and 57, regulating tuna and related species (including sharks) in the High Seas and in the Exclusive Economic Zones (EEZs) of the Coastal States.


The IOTC has the following structure:

Commission: responsible for adopting management and conservation measures in the regulatory area. In terms of the decision-making process, decisions are adopted by a two-thirds majority.

The Scientific Committee was set up in 1996. It advises the Commission on research and data collection for the managed stocks.

The Compliance Committee was established in 2002. It reports to the Commission on the level of compliance by the Contracting Parties, providing for technical advice and guidance.

The Standing Committee on Finance and Administration was established in 2002. It is responsible for all administrative and financial matters, including budget related issues.

 The Secretariat is based in Victoria, Seychelles, and is responsible for the implementation of the Commission's guidelines and activities.

 Eligibility conditions:

(a) hold a valid fishing license in accordance with Article 6 of the Control Regulation (Regulation 1224/2009);

(b) implementation of the relevant IMO vessel identification system, if required under Unions law;

(c) the fishing vessel is not on a IUU vessels list adopted by any RFMO and / or the Union under the IUU Regulation;

(d) the flag Member State has fishing opportunities under the fisheries agreement in question;

(e) have a vessels satellite monitoring system (VMS) installed and operational;

(f) Have a system for the electronic filling and transmission of fishing logbook data installed and operational.

 Forbidden species:

Sharks: It is prohibited to keep on board, transship or land any carcass or whole carcass of Bigeye thresher of any species of the Alopiidae family in any fishery. It is also prohibited to keep on board, transship or land any carcass or whole carcass of white-finned shark (Carcharhinus longimanus) in any fishery, except in the case of vessels below 24 meters that exclusively carry out fishing operations in the exclusive economic zone (EEZ) of the flag Member State provided, that their catches are exclusively for local consumption.



All species caught, including incidental catches, must be duly recorded in the fisheries logbook. Any interactions with sea turtles and seabirds should also be recorded in a specific form, indicating the location of the interaction, the species in question and the situation of the animal after removal from the device, i.e. dead or alive. Vessels operating in the region are still required to implement mitigation measures aimed at reducing, and possibly eliminating, interactions with these species.


 Fishing gear:

  • Surface Longlines
  • Pole-and-line

 Observer Coverage:

In order to collect activity and catch data, IOTC has instituted a Regional Observers Program (ROP) to cover the fishing activities in the Regulatory Area. The collection of scientific data under this program is assured by IPMA. Scientific observers from this Portuguese Institute assure the compliance with IOTC ROP requirements.
