The pelagic fisheries beyond the continental shelves are currently managed with a range of tools largely based on regulating effort or target catch. These tools comprise both static and dynamic area-based approaches to include gear limitations, closed areas and bycatch limits. There are increasing calls for additional area-based interventions, particularly expansion of marine protected areas, with many now advocating closing 30% of the oceans to fishing. In this paper, we review the objectives, methods and successes of area-based management of blue water fisheries across objectives related to food production and environmental, social and economic impacts. We also consider the methods used to evaluate the performance of area-based regulations and provide a summary of the relative quality of evidence from alternative evaluation approaches. We found that few area-based approaches have been rigorously evaluated, and that it is often difficult to obtain requisite observational data to defin
