Reef Fish Biodiversity at Different Depths in Tunda Island, Banten Province, Indonesia

Reef composition and diversity of coral reef fishes play an essential role in the ecosystem. The fish is a crucial indicator health level ecosystems. benefit ecosystems to describe ecological services. This research intended determine among stations at different depths, consisting shallow water slope. Research sampling was done July 2018 2019 Tunda Island waters eight billowing distribution pattern. Collected data were by using Underwater Visual Census (UVC) on Belt Transects Method 250 m2 transect area (50 meters length 2.5 m either side). result showed 69 67 species total ware from 13 families Acanthuridae, Apogonidae, Blenniidae, Chaetodontidae, Ephippidae, Haemulidae, Labridae, Lutjanidae, Nemipteridae, Pomacentridae, Pseudochromidae, Scaridae Serranidae. community services structure included moderate stability category with H’ value ranging 1.19-1.60 1.23-1.44 slope, respectively. Diversity communities might be associated species' spatial over habitat's physical structure, but these patterns could highly scale-dependent. In general, it said that higher diversity, diversity.
