The results showed that the abundance of Diadema setosum individuals on Tablolong beach (0.46 ind/m²) while Tripneustes gratilla was dominant on Baliana beach (0.22 ind/m²). The highest species diversity index (D) was found in Lalendo (0,7) and the lowest in Tablolong (0,5), indicating moderate diversity. The uniformity index (E) was highest in Baliana (0.8) indicating a more even distribution of species than Tablolong (0.6), the dominance index (C) was highest in Lalendo (1.0), indicating a strong dominance of species at the site. The highest Index of Gonadal Maturity (IKG) value for Diadema setosum was found in Tablolong (26.9), while Echinometra mathaei in Lalendo (68.6).
