Physico-chemical parameters in Parangipettai coastal waters and Vellar estuary, Southeast coast of India

Physico-chemical parameters, species composition and seasonal variation in phytoplankton abundance have been studied in other regions of Indian coastal waters (Saravanakumar et al., 2008; Vengadesh Perumal et al., 2009). For confirming the good quality of water resources large number of physico-chemical parameters, extend and source of any pollution load must be know for which monitoring of physico-chemical parameters and pollutants is essential (Reddi et al., 1993). The hydro biological study is a pre-requisite in any aquatic system for the assessment of its potentialities and to understand the realities between its different trophic levels and food webs. Further, the environmental conditions such as topography, water movement, salinity, oxygen, temperature and nutrients characterizing particular water mass also determine the composition of its biota. Thus, the nature and distribution of the flora and fauna in the aquatic system are mainly controlled by the fluctuations in the physical and chemical characteristics of the water body. In Indian estuaries and seas the physico-chemical characteristics had been carried out by many workers (Gouda and Panigrahy, 1996, Rajasegar, 2003).
