The effluent parameters like Biochemical Oxygen Demand (BOD) (73%), Chemical Oxygen Demand (COD) (39%) and Nitrate (55%) were found reduced considerably during the treatment period of thirty days. The antioxidant concentrations of the plant were increased to cope up with the stress environment. Superoxide dismutase (SOD) in plants was increased to 70% during the treatment period. Peroxidase activity was also found to be increased from 0.02 to 0.26 mg/gFW. The increase in non-enzymatic antioxidants like chlorophyll indicated the health status of the plant during the treatment period. http://pubs.sciepub.com/env/7/1/2/env-7-1-2.pdf phytoremediation shrimp farming antioxidant Acrostichum aureum
