Effect of the organochlorine pesticide Methoxychlor (MXC) on biochemical composition of tissues of the snake head fish Channa punctatus adults was analyzed. Parameters like total protein, glycogen, total lipids in muscle & liver were determined. Additionally, oxygen consumption of the selected fish was recorded. The fish were exposed to different sub-lethal concentrations of Methoxychlor for a period of 72 hrs & the said biochemical parameters estimated at the end of the period. The 96 hr LC50 of Methoxychlor in Channa punctatus is 71 µg/L. At the selected concentrations of the pesticide, the fish suffered alteration in locomotary behaviour. There was a slight loss of coordination. Opercular ventilation increased as also the frequency of surfacing for gulping air. Muscle & liver protein showed significant decrease. Liver glycogen declined markedly. Muscle glycogen also decreased but marginally. There was a significant increase in consumption of dissolved oxygen.
