ABSTRACT

In the Present study, an attempt has been made to evaluate the effect of heavy metal Cadmium (CdCl2) on the hematological parameters of fresh water cat fish, Clarias gariepinus for 60 days of experimental duration. Two experimental group fish were exposed to two sub-lethal concentrations (0.4 mg/L and 0.8 mg/L) of Cadmium chloride. The fish from control and experimental groups were sacrificed after an interval of 15, 30, 45 and 60 days for assessing TEC, Hb. PCV, TLC, MCV, MCH and MCHC. The result of the study revealed that in comparison to control group fish, TEC, Hb, PCV and MCHC declined significantly (P<0.05) whereas TLC and MCV exhibited significant increase (P<0.05) in fishes of experimental groups. MCH contrarily
exhibited a fluctuating pattern. An inverse relationship was observed between duration of exposure and various hematological profiles such as TEC, Hb, PCV and MCHC. This study therefore, provides and insight about the hemotoxicity of Cadmium on Clarias gariepinus.
