Abstract
The freshwater fish, Channa striata fingerlings were exposed to 10% and 30% sublethal concentrations of (LC50 for 96h-0.38 ppm) monocrotophos for a period of 10, 20 and 30 days to study the effect of monocrotophos on the biochemical composition of various organs such as gill, liver, kidney, intestine and muscle. After stipulated time, the carbohydrate (67.21 in the gill, 65.15 % in the intestine, 56.71 % in the kidney, 70.88 % in the liver and 67.98 %), protein (8.76% in gill, 72.51% in intestine, 81.11% in kidney, 85.39% in liver and 89.82% in muscle) and lipid (58.83 50.78, 69.19, 60.62 and 71.13% respectively in the gill, intestine, kidney, liver and muscle) content in the various tissues of Channa striata under pesticide stress were found to be decreased when compared with control.
