Metabolic and antioxidant enzyme activity in hepatopancreas of the adult male freshwater prawn Macrobrachium malcolmsonii (H. Milne Edwards) exposed to paravanar river pollutants

Abstract

The hepatopancreas of freshwater prawn Macrobrachium malcolmsonii were exposed to paravanar river pollutants, activity of Lactate dehydrogenase (LDH), Succinic dehydrogenase (SDH), Glutamate dehydrogenase (GDH), Superoxide dismutase (SOD), Catalase (CAT) and Glutathione S-transferase (GST) were studied. Freshwater ecosystem are being polluted by a multitude of pollutants from various sources like, industrial effluents, municipal wastes, garbage’s, sewage pollutants and agricultural wastes etc. these pollutants contain heavy metals, persistent chemicals and pesticides are carried through food chain, their concentration increasing at each link present a threat to man when we consume the hydrobioants from polluted water. Due to such mixing of pollutants, global fisheries is facing constant decline in prawn stocks. The decreased and increased level of metabolic and antioxidant enzyme were observed, this may probably be attributed, due to the river receiving of effluent sources like untreated industrial, domestic and municipal wastes from the old and new town of Cuddalore District, Tamilnadu. The results are discussed in details.
