The IOTC has established Total Allowable Catches (TACs) and individual catch limits for yellowfin tuna, bigeye tuna, skipjack tuna and swordfish under several Conservation and Management Measures. This paper presents the catch limits calculated by the IOTC Secretariat for 2027, taking into account the applicable provisions of the Resolutions, adjustments for previous overcatches and, where relevant, the outcomes of Management Procedures. The calculations are based on the latest available catch data and are provided for review by CPCs ahead of their consideration by the Scientific Committee and subsequent dissemination through an IOTC Circular.
