Establishing marine protected areas (MPAs) helps restore overfished marine populations by limiting human activity and providing safe breeding grounds.

Because they offer places where fishing and other disruptive activities are either completely prohibited or severely restricted, marine protected areas (MPAs) are essential to the restoration of overfished marine populations. As a result, fish stocks are free from the stress of overfishing and can recuperate, procreate, and expand. MPAs support the preservation of biodiversity and the general well-being of marine environments. MPAs can promote conservation efforts and sustainable fisheries by boosting fish population abundance through the protection of vital ecosystems like coral reefs and spawning grounds. On the other hand, lifting fishing limits or raising quotas would make overfishing worse, and commercial fishing subsidies might put more pressure on marine resources.
