Abstract

This study aims to analyze the phyto-zooplankton community and aquatic environmental conditions of the Panjang and Pamujan Besar Islands in Banten Bay. The study was conducted for 3 months from May-July 2019 in six locations around the islands. The abundance, diversity, evenness, and dominance indices were analyzed.. Results showed that, the phytoplankton found consisted of 3 classes, i.e. Bacillariophyceae (30 genera), Cyanophyceae (2 genera), and Dinophyceae (5 genera), with the most abundant genera were Chaetoceros sp, Spirulina sp and Rhizosolenia sp. The zooplankton consisted of 8 classes, i.e. Bivalva, Ciliata (6 genera), Malacostraca (13 genera), Gastropods, Polychaeta, Sarcodina (1 genus), Rotifera (1 genus), and Urochordata (1 genus), with the most abundant biota were Nauplius, Calanus, and bivalve larvae. The abundance of phytoplankton and zooplankton varied from 38095 to 13038515 cell/m3 (phyto) and 4010-190475 ind./m3 (zoo). The diversity, evenness and dominance indices of the phyto and zooplankton were 0.693-2.146, 0.694-1,00, 0.160-0.341, and 0.780-2.027, 0.275-0.861, 0.160-0.500, respectively. Findings of the study illustrated the plankton community had moderate diversity and no dominant genera was found.
