<![CDATA[The coral fish association is a close ecological relationship between the coral fish community and its environment, namely coral reefs as its main habitat. The reduction in the turtle model skeletal transplantation media is the main attraction for conducting research. This study aims to determine the water quality parameters, diversity index and abundance of individual species. Sampling was carried out in the turtle model skeletal transplantation area using the Underwater Visual Census (UVC) method. The parameters observed include Salinity, Temperature, pH, Current, Diversity Index and Abundance of individual species. The results of the study showed that the water quality parameter values are in accordance with the established quality standards T.L I (Salinity 32.6 ppt, Temperature 31 ° C, pH 7.7 Current 0.05 m / s), T.L II I (Salinity 32 ppt, Temperature 30.6 ° C, pH 7.5 Current 0.07 m / s). The associated fish species are 9, namely (Petroscirtes mitratus, Meiachanthus grammiste, Chromis viridis, Siganus margaritiferus, Synanceia Verrucosa, Aeoliscus strigatus, Cheilinus chlorourus, Siganus Virgatus, Chrysiptera parasema). T.L I (H¹ = 23.5), (D = 0.58 ind/m²) and T.L II (H¹ = 23) (D = 0.44 ind/m²). The diversity index and abundance of individual species are higher in T.L I, this is influenced by the dry season factor where the waters tend to be clearer and receive higher sunlight intake.]]>
