Abstract: The study evaluated the effect of fluazifop-p-butyl on the kidney and liver electrolytes of Clarias gariepinus. Adult fish sample was purchased from biotechnology resource centre, Odi, Bayelsa State, Nigeria. The fishes were transported to the wet laboratory of the Department of Fisheries and Animal Science, Niger Delta University, Wilberforce Island, Bayelsa State, Nigeria. Adult Clarias gariepinus were exposed in various concentrations of the toxicants (0.00, 0.01, 0.02 and 0.03ppm) in a 30 day semi static bioassay. Thereafter, the fish was dissected and kidney and liver obtained. They were processed and analyzed using standard protocol. The electrolytes in the kidney and liver were respectively observed in the range of 0.02 – 0.15mmol/L and 0.10 – 0.15mmol/L (calcium), 3.90 – 13.10 mmol/L and 3.40 – 5.51mmol/L (potassium) and 65.50 – 150.00mmol/L and 61.00 – 177.50 mmol/L (sodium). The result trend showed significant decline and elevation of potassium content in the kidney and liver respectively. The sodium content showed significant decline in the liver and fluctuation in the kidney. While the calcium content showed significant fluctuation in both kidney and liver of the fish. The study found that electrolytes are useful parameter in determining the sublethal effect of fluazifop-p-butyl on potential non-target organism in the aquatic ecosystem.
