BHC was developed as an insecticide by French and British entomologist beginning about 1940. It is quite persistent on the plants, accumulates in the soil and in the animal ecosystem. The present paper deals with the study of carbohydrate content of digestive tract and gills of Channa gachua induced by BHC. PAS test for carbohydrate in BHC intoxicated fishes showed a slight increase in carbohydrate content in mucosa and submucosa of the intestine in initial stage of the low concentration (0.5 ppm). With the increase of concentration and duration of BHC gradual reduction of carbohydrate content was observed in different layers of the intestine and stomach. In gills short duration exposure of BHC showed heavy loss of carbohydrate content. But longer duration intoxication increase of carbohydrate content.
