Studies on Toxicity and some Biochemical (Glycogen) changes in the selected tissue of Cirrhinus mrigala(Hamilton 1822)exposed to sublethal concentration of HILTAKLOR (Butachlor, 50%EC)

The present study was undertaken to evaluate the toxicity and effects of a commercial formulation of the herbicide Hiltaklor on glycogen in the fish Cirrhinus mrigala (Hamilton1822) The toxicity for 24, 48, 72 and 96 h of Hiltaklor calculated by probit analysis, were determined to be LC50 values 329.5, 322.2, 292.4 and 287.9 ppb, respectively, when treated with Hiltaklor Behaviour changes observed and are also glycogen amount of different tissue ,i e Liver, Muscle, Brain, Gill, and Kidney were calculated and observed percentage decreased 28.08%, 27.92%, 31.42%,30.44% and 38.86% respectively.
