Composition of zoo - plankton communities at the wastewater treatment station in Dong Nai province

Abstract

This study was conducted to investigate zooplankton components at the wastewater treatment station of a industrial zone in Dong Nai province. Sampling was conducted at four positions (upstream river, lake 1, lake 2 and downstream river) in 3 months (December 2014, March and May 2015). 85 zooplankton taxa belonging to 45 genera in 5 main groups were identified. They are phylum Protozoa (11.8%), class Rotatoria (phylum Aschelmia) 67.1%, class Cladocera 11.8%, class Copepoda 5.9% and class Ostracoda 3.5% (phylum Arthropoda). Our results will complement data of zooplankton composition as well as contribute to the development of research and application of zooplankton in the water environment monitoring.
