Biodiversity and Community Structure of Zooplankton in The Domas Coastal waters of Banten Bay, West Java, Indonesia

Abstract

Abstract Domas coastal waters, located east of Banten Bay, have an enormous potential for fisheries resources closely related to the presence of plankton in the area. This study was carried out for 6 months, from August 2021 to January 2022, to examine the biodiversity and community structure of zooplankton in the Domas coastal waters. Sampling was carried out monthly at six stations distributed from coastal areas to the sea. Data on the zooplankton were examined for abundance, diversity, evenness, and dominance indices. Based on the observations, zooplankton in these waters consisted of 19 classes, namely Actinopteri, Appendicularia, Bivalvia, Branchiopoda, Cirripedia, Cnidaria, Copepoda, Ctenophora, Enteropneusta, Gastropoda, Gymnolaemata, Hydrozoa, Malacostraca, Ostracoda, Ophiuroidea, Phoronida, Polychaeta, Sagittoidea, and Thaliacea. The zooplankton found in abundance were Calanoida, Cyclopoida, and Nauplius. The number of taxa and abundance varied according to sampling time and location, 7-34 inds/m3 and 627-41386 inds/m3, respectively. The diversity, evenness, and dominance indices varied, 0.885-2.108, 0.327-0.797, and 0.172-0.601, respectively. Based on the results of these calculations, it can be stated that the diversity, evenness, and dominance of the zooplankton in these waters are classified as moderate.
