Abstract
The effects of sub-lethal concentractions, 2.51, 5.02 and 10.04 mg L-1 of monocrotophos on some haematological indices of Clarias gariepinus were investigated in the laboratory. The packed cells volume and TEC were significantly reduced (p>0.05) in fish exposed to the toxicant concentrations than in the control groups. However, the TLC, neutrophils and Lymphocytes were observed to be significantly higher (p<0.05) in the exposed fish compared to the control groups. The study shows that sublethal concentration of monocrotophos is harmful to Clarias gariepinus, therefore, the usage close to water bodies for fish production is dangerous.
