Across the seven species of major commercial oceanic tuna, 23 stocks are recognized for stock assessment and management (6 albacore, 4 bigeye, 4 bluefin, 5 skipjack and 4 yellowfin stocks). This document summarizes the stock status resultant from the most recent scientific assessments of these stocks, as well as the current management measures adopted by the RFMOs. In addition, this report describes the status and management of the 23 stocks using a consistent methodology in terms of two factors: Abundance and Exploitation Rate (fishing mortality). Until 2023, this report also included relative ratings for bycatch impacts by the different fishing methods. The information on stock status and management comes from the five tuna Regional Fishery Management Organizations (RFMOs) that assess and regulate tuna fisheries internationally. However, the information on bycatch impacts was from multiple sources and was not stock- or fishery-specific. Because of this, the ISSF Scientific Advisory Committee recommended that the Stock Status Report be limited to stock status and management, and that a separate ISSF report be created to summarize bycatch and other ecosystem impacts for major types of tuna fisheries.
