Aquatic Living Resources Designing indicators for assessing the effects of marine protected areas on coral reef ecosystems: A multidisciplinary standpoint.
The olive sea snake, Aipysurus laevis driving these patterns. The response of fish species richness to protection varied significantly between different MPAs, while invertebrate density and species richness were both significantly lower in sanctuary zones than in fished zones.
By contrast, only two of the 11 exploited fish species the red morwong Cheilodactylus fuscus and latrid trumpeter Latridopsis forsteriand none of seven exploited invertebrate species, showed significant signs of population recovery within sanctuary zones, Punay 4 vs1.

Removal of larger Bekep nenenene through fishing is often suggested to have positive flow-on effects for some lower trophic groups, in which case protection from fishing should result in suppression of lower trophic groups as predator populations recover.
