Assessment of seasonal variations in water quality parameters of Kadamba tank in Thoothukudi district of Tamil Nadu, India
Freshwater lakes 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 investigation was carried out in Kadamba Tank, Thoothukudi 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. On the whole study revealed that there was no significant change in water quality parameters between the stations and seasons in the Kadamba tank, with the exception of phosphate and chlorophyll ‘a’. There existed no positive correlation between phosphate and chlorophyll ‘a’ content of the water in the tank. Higher chlorophyll ‘a’ values of the lake in the range of 48.59 mg/m3 to 105.15 mg/m3 indicated the lake to be in the hyper eutrophic condition.
