Stock assessment of bigeye tuna in the western and central Pacific Ocean Rev 1 (23 July 2017), McKechnie S, G. Pilling, and J. Hampton. Oceanic Fisheries Programme. The Pacific Community, Noumea, New Caledonia.
This paper describes the 2017 stock assessment of bigeye tuna (Thunnus obesus) in the western and central Pacific Ocean. A further three years data were available since the last stock assessment was conducted in 2014, and the model time period extends to the end of 2015. New developments to the stock assessment include addressing the ecommendations of the 2014 stock assessment report (Harley et al., 2014), incorporation of new data such as a recent ageing of otoliths to estimate age-at-length for WCPO fish, investigation of an alternative regional structure, exploration of uncertainties in the assessment model, particularly in response to the inclusion of additional years of data, and improving diagnostic weaknesses of previous assessments.
