Abstract

The sea waters around Panjang and Pamujan Besar Islands (Banten Bay) are fishing grounds and recreation areas for local peoples around the bay. The purpose of this research is to find out macrozoobenthos community structure in sea waters of Panjang and Pamujan Besar Islands, Banten Bay. The research activity on the macrozoobenthos community structure was carried out in May - July 2019 at 6 station points scattered around those islands. Data analysis was carried out on density, diversity, evenness, and dominance indices. Based on the research results, there were 17 genera of macrozoobenthos from four classes, namely Bivalvia (1 genus), Gastropoda (7 genera), Malacostraca (7 genera), and Polychaeta (7 genera). Procopio sp., Nephthys sp., and Nereis sp. were the most common genera of the macrozoobenthos found at each station. Based on the calculation results, it was found that the density varied between 58 to 406 ind/m2. The value of the diversity, evenness, and dominance indices at each station varied from 1.00 to 2.842, 0.935 to 1.00, and 0.157 to 1.00, respectively. Based on these values, the condition of the aquatic ecosystem of Panjang and Pamujan Besar Islands has medium diversity, high evenness, and no dominant biota.
