Syantis yo diskite sou wòl pwason korayivò yo nan ekosistèm koray Reef yo, ak kèk konfli ki egziste sou si pwason sa yo gen yon nèt efè pozitif oswa negatif sou resif koray. Pou egzanp, Rotjan ak Lewis ref sijere ke pandan ke domaj korallivore ka varye soti nan minè a letal, yon kò k ap grandi nan prèv sijere ke menm retire retire li nan koray tisi ak kilè eskèlèt gen konsekans potansyèlman negatif pou kwasans koray ak / oswa kapasite. McClanahan et al. ref sijere ke predasyon enfliyanse gerizon nan koray transplantasyon nan Kenya; otè sa yo te jwenn ki pi piti siviv nan transplantasyon ki te fèt nan pak yo marinasyon evantyèlé akòz predasyon. Gen kèk etid yo te jwenn ke domaj nan predasyon pwason se pi mal pase domaj nan touris. ref

Scientists debate the role of corallivorous fishes in coral reef ecosystems, and some controversy exists over whether these fishes have a net positive or negative effect on coral reefs. For example, Rotjan and Lewis ref suggest that while corallivore damage can range from minor to lethal, a growing body of evidence suggests that even limited removal of coral tissue and skeleton has potentially adverse consequences for coral growth and/or fitness. McClanahan et al. ref suggest that predation influences recovery of transplanted corals in Kenya; these authors found that the lowest survival of transplants occurred in the unfished marine parks potentially due to predation. Some studies have found that damage from fish predation is worse than damage from tourism. ref
