Abstract
Rivers are significant not only for human populations but also essential for plant and animal diversity. These aquatic systems are unique and are rich in biodiversity at the same time are under constant threat due to bludgeoning human populations and their demand for land. Water quality plays an important role in productivity of lakes. Physical and chemical parameters of the water body such as temperature, pH, turbidity, conductivity, TDS, along with primary productivity vary seasonally and regular monitoring of these parameters may through light into the productivity of the system. The present present study was undertaken to assess the seasonal variations of water quality parameters of Nagore vettar and Uppanar river, Arasalar river and Thirumalairayan rivers are near in Nagapattinam District, to assess the seasonal variations in water quality parameters (Temperature, pH, dissolved oxygen, ammonia (NH3-N), nitrite (NO2-N), nitrate (NO3-N), phosphate (PO4-P), biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS) and chlorophyll ‘a’, variations in lake morphology and changes in fish assemblages.
