The Influence of Cypermethrin on the Biochemical Parameters of Clarias gariepinus

Abstract

The experiment was conducted to evaluate the effect of cypermethrin, a synthetic pyrethroids on
juveniles Clarias gariepinus (catfish). The effect was assessed based on the comparing the results
of biochemical examinations (glucose, Aspartate and alanine transaminase enzymes, total protein,
albumin, globulin, and cholesterol) in the blood of control and experimental group exposed to three
nominal concentrations of cyperking, 10EC Pesticide Preparation (active substance 100mg/l) of
cypermethrin in a static non-renewal bioassay for 96 hours. Fish exhibited progressive change in
behaviours. Biochemical evaluation showed significant higher values (P≤0.05) for Alanine
aminotransferase (ALT), Aspartate aminotransferase (AST), Albumin and glucose, Total protein,
globulin and cholesterol showed a significant reduction (P≤0.05) with significant difference
(P≤0.05) as compared to the control. Thus, concluding that cypermethrin is toxic to juveniles of
Clarias gariepinus. It is therefore recommended that awareness of the effect of pollution in aquatic
ecosystem should be conducted.
