Abstract

Makrozoobenthos are all types of sedentary organisms or move freely whose habitat’s in the bottom substrate of waters with a body size of more than equal to 0.5 mm. Benthos have a very important role in waters where macrozoobenthos communities must remain balanced so that aquatic ecosystems are balanced. This study aims to determine the type of macrozoobenthos, the abundance of macrozoobenthos and the structure of macrozoobenthos communities on artificial reefs in Penyusuk Marine, Bangka Regency which was sunk by PT. Arta Cipta Langgeng. Data collection will be carried out in May 2023 at an artificial reef in Penyusuk Marine, Bangka Regency. The determination of the research location point was carried out by purposive sampling and macrozoobenthos data collection using road sampling techniques and free hand picking methods. Measurement of environmental parameters was carried out in situ and ex situ as well as data analysis using Principal Component Analysis (PCA). The results of the study found 32 types of macrozoobenthos with a total of 2,745 individuals found at the three observation stations. The abundance obtained ranged from 46,04 ind/m2 – 49,01 ind/m2. The diversity value ranges from 0,60 – 0,87 so that was categorized as low, the uniformity value ranges from 0,19 – 0,27 as low was categorized and the dominance value ranges from 0,72 – 0,82 was high categorized.

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.
