Abstract
The experiment was conducted to evaluate the acute toxic of cypermethrin, a synthetic pyrethroids on juveniles of Clarias gariepinus. The effect was assessed based on the comparism results of haematology, examinations of control and experimental group exposed to five nominal concentration of cypavest, 10EC Pesticide Preparation (active substance 100mg/l) of cypermethrin in a static non- renewal bioassay for 96hours. Examination of haematology significantly showed higher value (P < 0.001; 0.01) of white blood cell (WBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), packed cell volume (PCV), monophilis and heterophilis; a significant reduction (P < 0.001, 0.01) in Red Blood Cell (RBC) and Lymphocyte was obtained as compared to the control.cypermethrin is therefore toxic to juveniles of Clarias gariepinus.
