The Indian Ocean Tuna Commission (IOTC) adopted a Management Procedure (MP) in 2022 to recommend the total allowable catch (TAC) for consideration by the Commission (IOTC Resolution 22/03). The bigeye MP is the first fully-specified MP to be adopted in the IOTC. The adopted MP schedule requires the MP to be run by the IOTC Scientific Committee in 2022, through the Working Party on Methods and Working Party on Tropical Tunas, to derive a recommended TAC for 2023 and 2024. This document describes the key data inputs to the MP and the TAC calculation given the agreed data. The full specification of the MP is provided in Williams et al. (2022), and the consideration of exceptional circumstances is provided Preece et al. (2022).
