Marine protected areas (MPAs) have been used as a tool to protect biodiversity, genetic diversity, habitat, and reverse declining trends in overfished populations across the world. Many of these MPAs allow at least some fishing while excluding a form of fishing deemed unacceptable (e.g. harvest that is destructive or targets a particular species or group of species), whereas others exclude all forms of harvest.
