Fisheries management scenarios evaluated in the analysis (HCR = harvest control rule; EEZ = exclusive economic zone).

Fig 1.
Percent change in maximum sustainable yield (MSY) under each emission scenario.
In the left column, maps show the percent change in MSY from 2012–2021 (“today”) to 2091–2100 in each exclusive economic zone. In the right column, the colored lines show the percent change in MSY (measured in 10-year running averages) relative to 2012–2021 (“today”) for each of 156 countries and the black lines show the percent change globally.
Fig 2.
Percent difference in mean catch and profits in 2091–2100 relative to 2012–2021 (“today”) from all stocks under each emission and management scenario.
Fig 3.
Percent difference in mean catch and profits in 2091–2100 relative to 2012–2021 (“today”) for 156 countries under three emissions scenarios (columns) and three management scenarios (rows).
The percentage labels indicate the percentage of countries falling in each quadrant of catch and profit outcomes. Note that changes in catch and profits do not always match. This occurs when climate change and management strategies differentially favor more productive but less profitable species relative to less productive but more profitable species.
Fig 4.
Influence of changes in maximum sustainable yield (MSY) on the ability for management to generate higher catch and profits in the future (2091–2100) relative to today (2012–2021).
Bars indicate the proportion of countries experiencing each combination of catch and profits trajectories under each emissions scenario, management scenario (rows), and change in underlying productivity (columns). The number of countries experiencing reductions in MSY increases under increasingly severe emissions scenarios (see column title for numbers). Although the number of countries experiencing gains in MSY decreases under increasingly severe emissions scenarios (see column title for numbers), the gains in MSY in these countries are actually magnified with increasing emissions (i.e., more fish stocks move into their exclusive economic zones with more rapid warming).
Fig 5.
Percent difference in mean catch and profits in 2091–2100 relative to 2012–2021 (“today”) for 156 countries under realistic adaptation implementing management at 5-year intervals.
Grey shading indicates countries without marine territories.
Fig 6.
Percent difference in cumulative catch and cumulative profits from 2012–2100 relative to business-as-usual for 156 countries under three emissions scenarios (columns) and two adaptation scenarios (rows).
The percentage labels indicate the percentage of countries falling in each quadrant of catch and profit outcomes.
