This study aimed to assess Sodium fluoride's toxic effects on the hematological parameters of Clarias batrachus. Sodium fluoride is a major pollutant in aquatic environment and exposure to sodium fluoride in the environment can lead to bioaccumulation in fish. In most aquatic habitats, fish are at the top of the food chain and are most vulnerable to the toxic effects of high levels of sodium fluoride. Juvenile C. batrachus (length 13.4 ± 1.3 cm, and weight 24.3 ± 3.5 g) were exposed to sodium fluoride at different concentrations (34.975 mg/l and 87.43 mg/L)for ten days. The hematological parameters were examined, including RBC, WBC count, PCV, clotting time, hemoglobin%, MCV, MCH, and MCHC. The parameters such as RBCs, Hb%, PCV, MCV, MCH and MCHC PCV substantially decreased whereas, WBC count was found to be increased in experimental groups. The derived hematological indices of mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration were equally altered compared to control. The results of this study demonstrate that exposure to Sodium fluoride is toxic to C. batrachus and induces alterations in the hematological parameters.
