Ten-year (2009−2018) average purse-seine tuna catches in tonnes (t) from the EEZs of ten Pacific SIDS and high-seas areas together with average projected changes to these catches by 2050 in tonnes and percentage terms under the RCP 8.5 and RCP 4.5 emissions scenarios (see Supplementary Fig. 6 and Supplementary Tables 11–14 for ranges of projected changes in catch).
^aThe three EEZ areas of Kiribati, which have been integrated to produce the total for Kiribati. FSM, Federated States of Micronesia; see Supplementary Fig. 1 for locations and definitions of all high-seas areas.
