CHANGES IN TOTAL LIPID CONTENT IN THE LIVER OF THE FRESHWATER FISH, MYSTUS SEENGHALA (SKYES 1839), EXPOSED TO SUBLETHAL CONCENTRATION OF METHOMYL 40 % SP CARBAMATE INSECTICIDE

This study has been undertaken to investigate the impact of sub lethal concentration of Methomyl 40 % SP Carbamate insecticide on total Lipid content in the liver of freshwater fish Mystus seenghala (Skyes 1839). During our present investigation fishes were exposed to the sublethal concentration (1/10th of 96hr LC₅₀ concentration) of Methomyl 40 % SP a carbamate insecticide for 10, 20 and 30 days respectively. The total Lipid content in the liver tissue was determined by the standard procedure from control fish and the fish exposed to sublethal concentration of Methomyl 40 % SP a carbamate insecticide. The results showed a significant decrease in the total Lipid content in liver tissues exposed to Methomyl a carbamate insecticide. The reduction in total Lipid content indicates that the test fish response to the toxicant stress.
