Macrozoobenthos community structure in sea waters of Panjang and Pamujan Besar Islands, Banten Bay, Indonesia

Abstract

The sea waters around Panjang and Pamujan Besar Islands (Banten Bay) are fishing grounds and recreation areas for local communities around the bay. The research activity on the macrozoobenthos community structure was carried out from May to July 2019 at 6 stations scattered around the islands. This study evaluates the macrozoobenthos community structure at the sea waters around these islands. Data analysis was carried out on density, diversity, evenness, and dominance indices. Based on the research results, there were 23 genera of the macrozoobenthos from four classes, namely Bivalvia (2 genera), Gastropoda (7 genera), Malacostraca (7 genera), and Polychaeta (7 genera). Pronospio sp., Nephthys sp., and Nereis sp. were the most common genera of macrozoobenthos found at each station. Based on the calculation results, the density varied between 58 and 406 ind/m2. The value of the diversity, evenness, and dominance indices at each station ranged between 1.00 and 2.842, 0.935 to 1.00, and 0.157 to 1.00, respectively. Based on these values, the sea water condition in Panjang and Pamujan Besar Islands has medium diversity, high evenness, and no dominant macrozoobenthos.
