Abstract

An epizootic of scleractini an coral became high attention by the scientist in these 3 decades. The environment factor changing altered the number of microbes in coral and compromising their health. Prigi Bay has been located in southern Java and connecting with the Indian Ocean. Many compromising health factors that are causing diseased coral such as competition (red filamentous algae, cyanobacteria, sponge, and flatworm),sedimentation damage and raising sea temperature (bleaching). The survey was conducted in 3 stations using belt transect 100 x 1 m in 7 m depth. Coral health data was obtained by underwater photography. The result showed that high cover percentage of coral was be found in station 2 (48.16%), the highest coral compromised health relevancy was 75.69% in station 3 that caused by sediment damage. The Pearson Correlation value for NO3 was 0.520, NO2 was 0.630 and sedimentation was 0.343. These environmental factors have a strong correlation to the compromised health prevalence.
