Sublethal effect of monocrotophos (pesticide) and ammonium chloride (fertilizer) was studied in the freshwater fish Oreochromis mossambicus, with reference to carbohydrate metabolism for a period of 96 h. The glycogen content was analysed in liver and muscle, while the lactate and pyruvate were assessed in blood along with liver and muscle. The results revealed that the glycogen content was found to be decreasing. In contrast increase in the tissues lactate and pyruvate level was found in the fishes exposed to pesticide and fertilizer individually and in combinations. The combined effects of these chemicals were more toxic to carbohydrate metabolism than the effect produced by the individual chemicals. The results were tested to search for statistical significance. The calculated lactate and pyruvate ratio (L/P) indicated that the fishes were under chemical stress.
