Ecosystem-Based Management and Marine Protected Areas. Ecosystem-based management (EBM) can be seen as a comprehensive strategy that includes the concern about the sustainable yield of fish alongside the ecosystem impacts of fishing and the impacts of fisheries management on human communities. While preventing overfishing goes a long way toward reaching its objective, protecting sensitive habitats from damaging fishing gear and reducing or eliminating bycatch of birds, mammals, and turtles must be given their due importance. Consideration should also be given to the trophic knock-on effects of fishing for one species that may cause other species less or more abundant. Marine protected areas are still considered the magic key to EBM, but their impact on total fish abundance has rarely been evaluated.
