ABSTRACT
In biomonitoring, the bioindicator groups (phytoplankton, zooplankton, macroinvertebrates) provide a broad categories of the ecological health of river systems, in which each biological group has its own distinct advantages. The various analytically biological approaches (e.g. richness, abundance, and pollution tolerance) together with the physical and chemical measurement, provide valuable information for ecological health and environmental assessment (MRC 2010; Kim & An 2015).
