a, Projected changes in total biomass of skipjack, yellowfin and bigeye tuna in the combined EEZs of the ten Pacific SIDS and EPO-C under the RCP 8.5 and RCP 4.5 emissions scenarios in 2050 relative to the average biomass from these areas in 2009−2018. b, Projected changes in total purse-seine catch in the EEZs of the ten Pacific SIDS and EPO-C under the RCP 8.5 and RCP 4.5 emissions scenarios in 2050 relative to the average catch from these areas in 2009−2018. The dark column in each histogram represents the average change from the four ESMs. The columns on either side of the average represent the maximum and minimum changes projected by the range of ESMs. See Supplementary Tables 5–8 for further details of changes in biomass and Supplementary Tables 11–14 for details of changes in purse-seine catch. Projected changes in biomass and catch for all high-seas areas combined are presented in Supplementary Fig. 5.
