Tuticorin Thermal Power Station (TTPS) uses the adjacent sea water as the coolant water and the
sea water after use is discharged into the same environment at an elevated temperature. The impact of coolant
water discharge on hydro biological characteristics was investigated for a period of one year in three different
stations fixed in the sea covering 3 km distance from TTPS. This study on coastal ecology has been carried out
especially with special reference to the water quality, species diversity and biomass of plankton, nekton and
benthos. The physiochemical parameters were ranged in temperature (25 to 42ºC), dissolved oxygen (3.7 to
6.1 mg/l), salinity (24.6 to 36 ‰) was recorded. About 11species of phytoplankton and 10 species of
zooplankton were recorded. Present study shows that the elevated temperature of 42ºC resulted in the
suppression of phytoplankton, zooplankton, fin fishes and shell fishes. The results clearly indicate that, elevated
coolant water temperature has been deteriorating fish population in the Tuticorin bay.
