    Stock assessment of South Pacific albacore tuna WCPFC-SC14-2018/ SA-WP-05 Rev. 2 (2 August 2018), Tremblay-Boyer L, J. Hampton, S. McKechnie and G. Pilling. Oceanic Fisheries Programme, The Pacific Community (SPC).


    This paper describes the 2018 stock assessment of albacore tuna (Thunnus alalunga) in the southern hemisphere component of theWestern and Central Pacific Fisheries Commission (WCPFC) convention area. A further three years data were available since the last stock assessment was conducted in 2015, and the model time period extends to the end of 2016. Further developments to the stock assessment have been undertaken to address the recommendations of the 2015 stock assessment report (Harley et al., 2015), to address the recommendations of the 2018 pre-assessment workshop (PAW; Pilling and Brouwer (2018)), and to explore uncertainties in the assessment model, particularly in response to the inclusion of additional years of data and to improve diagnostic weaknesses in previous assessments. This assessment is supported by the analysis of longline CPUE data, background analyses of other data inputs and definition of the regional and fisheries structures for the updated assessment (Tremblay-Boyer and McKechnie, 2018).
