a, Change (%) in each stressor associate with a 10% reduction in the parameter value (black cell indicates stressor change >20%). b, Change (%) in each stressor under four scenarios (defined in Supplementary Table 8) relative to the current estimate. Arrows indicate changes greater than 50%. Additional aquaculture scenario results displayed in Supplementary Fig. 15 and capture scenario results in Supplementary Fig. 16 Source data.
