The aquatic environment was affected by the increasing use of metal oxide compounds in modern industrial world. The present study was performed to investigate the effect of sub-acute exposure of zinc oxide on hematological and biochemical changes in Labeo rohita. The acute toxicity (LC50) of zinc oxide exposed to Labeo rohita for 96hrs was 3.95mg/L. Based on acute toxicity test, 0, 1/10, 1/50 and 1/100th of LC50 concentration were selected for treatments T0, T1, T2 and T3 for present sub-acute study. At the end of 7th and 14th day, haematological and biochemical parameters in gill, muscle and liver of fish were analyzed. The RBC, hemoglobin and hematocrit count was significantly decreased (p<0.05) compared to that of control and WBC and platelets level was significantly higher than control during the exposure period. The protein, carbohydrate and lipid content were reduced with significant level (p<0.05) compared to the respective control group on 14th day of exposure period. Hence, this study revealed that the zinc oxide at sub-acute concentration affects hematological and biochemical parameters of Labeo rohita.
