Plankton community structure in situ cibeureum, tasikmalaya city, West Java

Abstract

The purpose of this study was to determine the plankton community structure as a reference for the management of Situ Cibeureum. This research was conducted on September to November 2021. This study used a survey method with purposive sampling. The plankton community structure in Situ Cibeureum consists of 13 classes, 9 classes of phytoplankton and 4 classes for zooplankton. The abundance of phytoplankton 195 Ind/L – 310 Ind/L and zooplankton 25 Ind/L – 41 Ind/L. The Simpson phytoplankton diversity index value was ranged 0.45±0.29 – 0.60±0.19 and 0.62±0.21 – 0.76±0.07 for zooplankton while the phytoplankton dominance index was ranged 0.40±0.19 – 0.55±0.29 and 0.62±0.21 – 0.76±0.07 for zooplankton. The total biomass of phytoplankton in Situ Cibeureum was 43,433.26 µg/l. Based on the plankton community structure, Situ Cibeureum is categorized as good for supporting fishery activities and one type of activity that might be developed in Situ Cibeureum is restocking tilapia (Oreochromis niloticus).
