This dataset corresponds to the latest version of the raw estimates of annual catches in live-weight equivalent for the all species for which catches are submitted to the Secretariat, aggregated by year, IOTC statistical area and fishing fleet. Data are reported by calendar year and extend back to the 1950s, when industrial longlining started in the Indian Ocean.
The data originate from the IOTC Contracting Parties and Cooperating Non-Contracting Parties (CPCs) as per the IOTC data requirements (Resolution 15/02). They are submitted annually, mostly using IOTC Form 1RC, and curated by the Secretariat for dissemination prior to IOTC Working Parties and other scientific data users.
Previous update (2025-10-16) : Catches for Indonesia in 2024 were repeated from 2023, following feedback from Indonesia that additional checks and data processing were ongoing to improve their data
