Fig. 2: Projected effects of climate change on the distributions of the three tuna species caught by purse-seine fishing in the Pacific Ocean.

From: Pathways to sustaining tuna-dependent Pacific Island economies during climate change

Fig. 2

Average biomass distributions (kg km–2) of skipjack, yellowfin and bigeye tuna in the Pacific Ocean basin for 2015 (2011−2020) (top row) and mean anomalies (kg km–2) from the average 2015 biomass distribution of each tuna species projected to occur by 2050 (2044−2053) under two emissions scenarios, RCP 8.5 (middle row) and RCP 4.5 (bottom row). Shading indicates areas where projections from all four ESMs (Methods) agree in the sign of change, excluding near-zero changes (white zones).
