In a study published in the Journal of Marine Biology, researchers examined the populations of various fish species in coral reef ecosystems. Findings indicated that overfishing has lead to significant declines in certain species, while invasive species are beginning to dominate these marine environments. The researchers emphasized the fragile balance within these ecosystems and the critical role that each species plays in maintaining coral health. They recommended stronger fishing regulations and the establishment of marine protected areas as essential steps for preserving biodiversity.
