Fish community dynamics in a coastal no-take marine protected area compared to a harvested area before and after protection from fishing
Abstract An ecosystem's ability to maintain key functions during environmental change is largely determined by its biodiversity. We compared fish species composition, richness, diversity, catch per unit effort (CPUE), and fish size between a 1.5 km2 no-take marine protected area (MPA) and a nea...
