Volume-weighted averages of tuna fishery FPI scores. Fisheries are grouped by by final product market (Output panel a; Input panel b) with a comparison to all non-tuna FPI case studies (grey solid field), governing RFMO (outcomes panel c; enabling conditions panel d), and industrial scale of production (outcomes panel e; enabling conditions panel f) with a comparison to non-tuna FPI case studies (yellow solid fields). Radial axes reflect volume-weighted average of the dimension score, with higher scores interpreted as better performance only in the outcome panel. On the outcome panels, a pink outer ring indicates the dimension of the Ecology indicator; orange, the dimensions of the harvest sector indicator; and beige, the dimensions of the post-harvest sector indicator. On the enabling condition panels, shades of green indicate dimensions comprising different components of the enabling conditions
