Abstract

  Coral reefs are organisms that live at the bottom of the water and take the form of sturdy limestone formations capable of withstanding the force of ocean waves. Ecologically, coral reefs serve as habitats where various animal and plant organisms seek food and shelter. This research aims to analyze the coral reef ecosystem conditions in the waters of Panjang Island and provide recommendations for sustainable management of marine biodiversity in the waters of Panjang Island, Central Bangka Regency. The Underwater Photo Transect (UPT) method involves underwater photography using a digital or regular digital camera equipped with a waterproof housing to withstand seawater exposure. The research results indicate that the percentage of live coral cover in the waters of Panjang Island ranges from 70.07% to 14.07%, categorizing it as fair to poor according to the Minister of Environment Decree No. 4 of 2001 on the Standard for Coral Reef Damage. Fourteen coral growth forms were identified in the waters of Panjang Island, belonging to 17 coral genera. Recommendations for managing marine resources on Panjang Island include sustainable tourism development. Environmentally based tourism development can serve as a solution for sustainably utilizing coral reefs and promoting improving coastal and fisheries management based on Marine Conservation Areas.

Abstract

This study aimed to analyze the community structure of reef fish in the small island waters of Central Bangka. The research was conducted in March 2022 in the waters of Bebuar Island, Ketugar Island, Ketawai Island, and Gusung Asam Central Bangka Regency, Bangka Belitung Islands Province. The coral reef survey method uses purposive sampling and the coral reef fish visual census with data analysis of abundance, diversity index, uniformity, and dominance. In-site water quality measurements included six parameters: temperature, salinity, current, brightness, depth, and pH. The results showed that coral reef cover from 44.60 - 87.00% with the medium to very good category. The abundance of reef fish from 1 to 3 individuals/m2 was dominated by 18 species of the Pomacentridae family. The reef fish diversity index ranged from 2.47 to 2.90, including the medium category. The uniformity index value ranged from 0.79 - 0.94, including the high category, indicating that the species found were evenly distributed across all stations. The dominance index value ranges from 0.07 to 0.15, including low, where no species dominates significantly and the fish are evenly distributed. Temperature, brightness, pH, and salinity are factors that support the growth of coral and reef fish. A water current speed of 0.05 – 0.20 m/s is quite helpful in cleaning coral reefs from mud and can supply oxygen. Water conditions were categorized as good and fulfilled the seawater quality standards.
