Professors Christopher Costello and Steven Gaines have recently sent ripples throughout the fishing world.  Last year, they published a groundbreaking study in the journal Science, showing that fisheries under catch shares management dramatically outperform fisheries under traditional management in terms of preventing overfishing.  Their most recent commentary discusses how catch shares can be customized to meet specific goals of a fishery and to address particular concerns.  It also looks at how catch shares might be made more effective by, for instance, combining them with protected areas.
