Joonu.J, IMPACT OF PESTICIDE CHLORPYRIFOS ON THE FRESH WATER FISH, OREOCHROMIS SPP(2017)SDRP Journal of Cellular and Molecular Physiology 2(1)p:93-99
The stress of pesticides is a very common factor today in human and animal health. Fishes can serve as bio indicators of environmental pollution, since they are directly exposed to chemicals resulting from agricultural production via surface run off or directly through the food chain of the ecosystem. Haematological parameters, protein levels etc , are considered as the index of the total body and therefore they are important in diagnosing structural and functional strategy of fish. Two different stages of fishes (juveniles and adults) were chosen for experimenting and a narrow range of pesticide chlorpyrifos was used in juvenile fishes( ranging from 10ppm to 30ppm) and in adults two different concentrations(both narrow and broad) range of pesticide were used The broad range concentration is 1000ppm or 1ml. And in narrow range in adults, three different concentrations were used (10ppm,20ppm, and 30ppm). Various biochemical and histological parameters of the pesticide treated fishes were tested and compared with that of the control. This proved the toxic effect of the pesticide in the aquatic habitat.
