The present work related to effects of certain pesticides on histopathology of Gills of an air breathing teleost, Channa gachua (Bloch). exposed to lethal and sublethal concentration of electroplating industry effluent for 24, 48, 72 and 96 hrs (LC50 at 20%, 19.5%, 19%, 18.5% respectively). Similarly the test fish were also exposed to acute concentrations of heavy metals like Copper, Nickel and Zinc. For Copper, the LC50 values were found to be 180 ppm, 88 ppm, 40 ppm, and 20 ppm respectively. The LC50 values for Nickel were found to be 1200 ppm, 600 ppm, 300 ppm and 150 ppm respectively. The LC50 values for the heavy metal Zinc was found to be 630 ppm, 528 ppm, 429 ppm and 330 ppm respectively. At the end of exposure period, the fishes which survived were sacrificed and gills, liver, kidney and gonads were removed and fixed in bouins’ fixative for 24 hrs. Simultaneously a control aquarium was also maintained. The results are significant from environmental pollution and human health point of view.
