Abstract

A study on the biodiversity of benthic macroinvertebrates and surface water quality was carried out from February to April 2015 in five sampling sites located within Mahidol University, Nakhon Pathom Province. Water quality was assessed using physiochemical parameters in combination with macroinvertebrate composition and biodiversity indices. Correlations of biodiversity indices and physiochemical parameters were also determined. A total of 2,641 benthic macroinvertebrates from 16 families in 10 orders were collected and identified. The most abundant family was Corixidae in the order Hemiptera. Most of physiochemical parameters indicated that surface water in all study sites were still suitable for aquatic animals. The correlation analysis showed that temperature, dissolved oxygen (DO) and pH correlated with diversity index (P<0.01). Thus, benthic macroinvertebrates can be used as a biological indicator for the assessment of water quality.
