Compendium of Active Conservation and Management Measures for the Indian Ocean Tuna Commission - Last updated: 19 November 2025

At each Session of the Commission, Members may adopt Conservation and Management Measures concerning the management of tuna and tuna-like species under the IOTC mandate as well as the fisheries which target them. These decisions are passed in the form of either Resolutions or Recommendations.

Resolutions are binding on the Commission Members, unless there is a specific objection on the part of a Member, and require a two-thirds majority of members present and voting.
Recommendations are slightly different in that they are not binding on the Members and rely on voluntary implementation. The Commission may, by a simple majority of its Members present and voting, adopt Recommendations concerning conservation and management of the stocks for furthering the objectives of the IOTC Agreement.

These Conservation and Management Measures, both active and superseded, can be searched using a range of search criteria, via either the Basic Search or Advanced Search engines below.
