    Executive Summary

    This paper describes the 2021 stock assessment of albacore tuna (Thunnus alalunga) across the South Pacific ocean (south of the equator), incorporating the Convention areas of the Westernand Central Pacific Fisheries Commission (WCPFC) and the Inter American Tropical TunaCommission (IATTC). A further three years of data are available since the last stock assessment was conducted in 2018; the model time period now extends from 1960–2019.  The 2018 assessment was restricted to the convention area under the jurisdiction of the WCPFC (Tremblay-Boyer et al., 2018a).  This assessment is the first complete attempt at a spatially structured South Pacific wide assessment, although a previous assessment applied an areas-as-fleets approach to thestock across the entire South Pacific (Hoyle et al., 2012)
