Updated CPUE standardizations for bigeye and yellowfin tuna caught by Taiwanese longline fishery in the Indian Ocean

Updated Taiwanese longline fishery data to 1979-2018 were used in this analysis. We used cluster analysis to classify longline sets into groups based on the species composition of the catch, to understand whether cluster analysis could identify distinct fishing strategies. Bigeye and yellowfin tuna CPUE were then standardized. All analyses were based on the approaches used by the collaborative workshop of longline data and CPUE standardization for bigeye and yellowfin tuna held in April 2019 in AZTI, Spain.
