Changes in Ascorbic Acid in Liver, Muscle and Gills Due to Dimethoate Induced in Freshwater Fish Puntius ticto

In the present investigation, ascorbic acid content was observed in the liver, muscle and gills in the Punctius ticto fishes, exposed to sub lethal concentration of dimethoate. Ascorbic acid is a key antioxidant in the liver, gill and muscles of fish. Intrinsic properties of ascorbic acid beyond acting as an antioxidant are important in its role as a key molecule in the metabolism of fish.

The present research work deals with the evaluation of the ascorbic acid on dimethoate induced in Puntius ticto. The dimethoate pesticide EC 30% was administered directly in the water contained in the aquarium at the dose of 1.3 ppm (1/5), 0.63 ppm (1/10) and 0.43 ppm (/15) respectively for 96 hrs hours after the dose calculation through LC50. Thereafter, ascorbic acid was administered to each pesticide treated group. All over the experiment the ascorbic acid content gradually increased in the liver, muscle and slightly decreased in the gills of the intoxicated fishes.
