the video describes catch share programs as a potential solution to over fising. under these programs the right to catch as portion of the total allowable harvest would be traded among individuals, communities, and companies. how do harvest share programs prevent over fishing? the value of a catch share dpends on the health of the fish population so fishermen have an incentive to preserve the population, costal communities can allocate permits only to fishers who promise to fish sustinably, local governments ca set the allowable harvest as lowas they want, so fishers have no choice but to fish at sustainable levels, less efficient fishing operations will find it more profitable to trade catch shares to operations that can harvest more fish with fewer resources
