ABSTRACT

Family Chaetodontidae have been regularly identified as indicator species of coral reef health with almost a quarter of the species feeding on polyps coral. This study was conducted in September – October 2018 in Pasumpahan Island, Padang City. This study aimed to determine composition and comunity structure of Chaetodontidae and the research used underwater fish visual cencus method with limitation of 2.5 meters of view to the left and to the right along the line transects on coral reef. The results found that 5 species of Chaetodontidae fish which belong to two genera; Heniochus and Chaetodon. There were three species of Chaetodontidae (i.e Chaetodon triangulum, C. vagabundus and C. trifasciatus) and two species of Heniochus (i.e Heniochus pleurotaenia and H. singularis). Diversity index ranged between 0.31-0.97 showed low diversity. Dominance Index was low categorized with value between 0.037-0.076. Similarity index are low categorized with value between 0.16-0.80. The low index values for all of the parameters may indicate a low quality of the coastal area community due to the human interferences.
