A study has been undertaken to enlighten the water quality parameters of coastal water of Kuduvaiyar estuary and Kuduvaiyar east coast was selected as the reference site. The concentration of water quality parameters like pH, DO, Ammonium,Nitrate, BOD, Sodium, Chloride,Sulphate and Fluoride were done in the laboratory as per the standard methods compared with Fisheries and aquatic life standard value. The reason for choosing the coastal water level due to the continuous discharge of agricultural, domestic sewage and industrial effluent in the estuary. The present baseline information of the physicochemical properties of water would form a useful tool for further ecological assessment and monitoring of Kuduvaiyar estuarine water of South East coast of India. The conclusion of the present study is that physico-chemical parameters influence the Ichthyofaunal diversity and Kuduvaiyar estuary are not extremely pollutant but at the same time there is a possibility of gradual addition of pollutants in due course. It reveals that the estuarine environment is largely influenced by the annual cycle of monsoon.
