Macrozoobenthic Community Structure in the Kemayungan-Linduk Waters, Banten Bay

Abstract

The objective of this study was to investigate the macrozoobenthic community structure in Kemayungan-Linduk waters, Banten Bay. This study was conducted for three months from February to April 2021. Van Veen grab was used to gather macrozoobenthic samples in triplicate at six sites. Environmental parameters such as depth, Secchi depth, water temperature, turbidity, pH, dissolved oxygen, and salinity were also measured. According to our findings, Gastropods, Bivalvia, Malacostraca, Polychaeta, Clitellata, Insecta, and Ophiuroidea were found in the Kemayungan-Linduk waters. Macrozoobenthic density varied across time, ranging from 1646 to 5787 individuals/m2, with the maximum density occurring in April 2021. Macrozoobenthic diversity based on the Shannon-Wiener index ranged from 0.34 - 1.69. The Pielou’s evenness index varied from 0.10 - 0.45, Simpson dominance index varied from 0.31 - 0.89. Macrozoobenthic density ranged from 30 - 16883 individuals/m2, and the highest density was at Station 4, based on location. The Shannon-Wiener diversity index varied from 0.28 - 1.96, whereas the evenness and dominance indexes were 0.08 - 0.95 and 0.16 - 0.92, respectively. Based on spatial observations, the macrozoobenthic community in Kemayungan-Linduk waters displayed low to moderate diversity, as well as low to high evenness and dominance.
