Acute and Subchronic Effect of Monocrotophos on Haematological Indices in Catla Catla (Hamilton)

The present study was aimed to find out the effect of sublethal concentration of monocrotophos on freshwater fish Indian major carp Catla catla. The fishes were exposed to sublethal concentration (0.0250mg/l) for 5days (acute) and 30 days (sub chronic). Haematological parameters such as TEC, PCV, Hb, MCH, MCHC, TLC, MCV and differential blood cell count were carried out to assess the effect of pesticide on fish physiology. Significant changes were observed in the blood cell indices of fishes exposed to pesticide compared with control. A statistically significant decrease in the TEC, Hb, PCV, MCH, MCHC, TLC and increase in MCV were observed in the 5 and 30 days exposure compared with control. The present results indicate that the pesticide monocrotophos induce changes in the blood indices which may be used as indicator for the health status of fish.
