Zooplankton community structure in Cengkok Coastal Water and it’s around, Teluk Banten

Cengkok coastal waters of Banten Bay are one of the waters that have many anthropogenic, industrial, and aquaculture activities. Zooplankton would like to become a bioindicator for the water’s condition. This study aimed to analyze the biodiversity and structure of the zooplankton community in waters. The study was carried out, from May to September 2019 at five stations. Data analysis calculating the value of composition, abundance, similarity index, biological index, and PCA. Based on the study obtained, the zooplankton consisted of 17 classes and 47 genera. Based on location and time, respectively, the average composition of Malacostraca (47.2% and 49.8%) and Ciliata (40.6% and 37%). Based on location and time observation, the average diversity index (H’) was (0.8-1.6) and (1.2-1.6); evenness index was (0.7-0.8) and (0.6-0.9); and index dominance was (0.3-0.6) and (0.3-0.4) respectively. The PCA results divided into 3 groups and the results of the similarity index showed the zooplankton abundance had the highest similarity value at Stations 3 and 5 (0.829) and based on water parameters showed that the highest similarity is 0.98. Based on the community structure index, it is found that the condition of the zooplankton structure community in Cengkok coastal waters (Banten Bay) was medium stressed.
