Subhan Subhan, Asrin Ginong Pratikino

Abstract


Study on coral recruitment in artificial reefs was carried out in Hari Island, Southeast Sulawesi. Data collection was conducted by calculating the number of genus colony and measuring coral size using visual census method equipped with scuba diving and an underwater camera. The construction of artificial reefs would vertically expand the profile of the survival of juvenile coral recruitment, where 95 new colonies of the recruitment had successfully been observed. Moreover, there were 10 genus of stony coral (Scleractinia) managed to be identified with the abundance proportion of Pocillopora, Acropora, Fungis, Leptoseris, Cynarina, Seriotopora, Acanthastrea, Favites, Montipora, Oxypora. The entire coral recruitment was dominated by genus Pocillopora reaching 80.0%. The coral recruitment in artificial reefs showed that there was potential coral recovery in the island.
