Implementing EBM requires taking careful account of ecosystem conditions that may affect fish stocks and their productivity. For example, the creation of "no (fish)-take" zones or other types of Marine Protected Areas such as those which safeguard fish spawning, breeding or feeding grounds. Protection of these habitats helps depleted fish populations to recover and ensures the long-term sustainability and productivity of a fishery.

Implementing EBM also requires taking careful account of how fishing affects marine ecosystems. In order to maintain healthy fisheries, catches may need to be reduced to allow the species to continue to play its natural role in ecosystems. In addition, fishing gear that eliminates or minimizes the incidental take of non-target species (bycatch) and damage marine habitats may need to be implemented.

EBM recognizes the economic, social and cultural interest of all stakeholders in a fishery and how these interests affect resource management. By managing human impacts, the EBM approach is more likely to succeed there where many other initiatives have failed.
Finally, for EBM to be successful, management organisations will need to stop granting "open access rights" to vessels (e.g. fishing areas, allowable fish catches, etc..) that encourages overfishing. Instead, a well-designed Rights-Based Management (RBM) strategy, a mechanism through which access to the sea is controlled, will provide the necessary economic incentives for sustainable fishing.
