ABSTRACT
Lebaycid (Fenthion), a common organochloride pesticide shows non-target effect on the Indian carp,Cirrhina mrigala Hamilton. This study presents a brief report on the impact of incipient lethal levels (1/4th and 1/10th of fenthion on the concentration of substrates (carbohydrates, lipids and proteins) in the four important tissues - brain, gill, intestine and liver. Maximum decrease in glycogen level was observed in liver tissue (-54.4/30 days) and minimum in Intestine tissue (-0.86/60days). Maximum decrease in protein levels were observed in brain tissue (-40.9/30days) and minimum in Liver tissue (1.6/60 days). Maximum and minimum decrease in lipid levels were observed in the liver tissue (-51.8/30 days and -0.5/60 days).

Keywords : Fenthion, C.mrigala, glycogen, protein, lipids. brain, gill, intestine, liver. 96h LC50, probit
