Abstract

Tejakula District is one of the tourism development areas in Buleleng Regency, Bali, based on the condition of the waters, which are classified as good. The increasing population in this location has caused increased exploitation of coastal and beach areas, especially in coral reef areas. The coral covers in the Tejakula utilisation area has been damaged due to natural and human factors. This study aims to obtain information on the percentage of living coral reefs, the abundance of Chaetodontidae fish, and their relationships. The Underwater Photo Transect (UPT) method was used for coral reef data collection, and Chaetodontidae fish data were collected using the Underwater Visual Census (UVC). The CPCE 4.0 application was used for coral reef data processing. The Chaetodontidae fish data were calculated based on the number of individuals, and then identified the type of genus. The relationship between the percentage of coral cover and the abundance of Chaetodontidae fish was analysed using the Pearson correlation. Almost all stations in Tejakula Waters had weak category coral cover. The results on the abundance of Chaetodontidae fish found five genera: Chaetodon, Parachaetodon, Heniochus, Forcipiger and Hemitaurtys. The relationship between the percentage of cover and fish in Tejakula Waters was in the weak category with r = 0.091. Supervision, monitoring, and attention to activities around Tejakula Waters are needed to ensure the coral reef ecosystem remains well maintained.
