Abstract

Plankton belongs to one of biotic factors, which plays a vital role in their primary productivity as well as water quality indication in aquatic ecosystems such as mangrove areas. A suitable water quality gives significant contribution to biodiversity in a way that they maintain its conservation function. A study of plankton community was conducted based on the analyses of species diversity, dominance, and evenness in mangrove restoration areas of Batukaras and Bulaksetra to assess their reproductive performance as indicator of the water quality in the southern coast of West Java province, Indonesia. This observation was done at 54 spots of two study sites during wet / rainy season in order to assess the primary productivity and plankton community, including its periphyton. The result showed that plankton diversity in Batukaras had higher performance in most of Ecological Indices including the primary productivity performance, as compared to the one in Bulaksetra. The phytoplankton dominated on both study sites was Bacillariophyceae,while zooplankton was dominated by Crustacean. Primary productivity results showed that Batukaras happened to be in euthropic level, while Bulaksetra in mesothrophic one. In general, the results indicate that the areas in both study sites were moderately polluted.
