Effect of Aquathol on Biochemical Constituents of the Freshwater Cat Fish- Heteropneustes Fossilis

The present investigation has been undertaken to assess the impact of aquathol a weedicide on some biochemical parameters of a freshwater cat fish, Hetropneustes fossilis.The LC 50.Value for 96 hours was calculated following probit analysis method.Fishes exposed to various sublethal concentrations of aquathol (0.5 ppm, 1.0ppm, 1.5 ppm and 2.0 ppm) elicited a gradual and significant hyperglycemia with the increase of concentration as well as the increasing time-intervals, i.e. from 24 hours upto 96 hours.The liver and muscle glycogen showed decreasing trend to that of blood glucose.The anomalies in various biochemical parameters following different sublethal exposure of aquathol has been discussed.
