Toxicity of crude oil products and detergent on serum alkaline phosphatase concentration of Clarias gariepinus juveniles

Abstract

The comparative effect of exposing Clarias gariepinus juveniles (100.20 + 0.8g) to diferent concentrations of crude oil products and detergent were studied. Bonny Light Crude oil (BLCO), Premium motor spirit (PMS), Dual purpose kerosene (DPK) and Ariel Enzymax Detergent (AED) were respectively applied at three concentratons, 2.00, 4.00and 6.00mi/L as well as a control experiment 0.00ml/L with no toxicant for two hours (2 hours) toxicity period. Increased serum alkaline phosphatase and low degree of toxicity were recorded in the fish samples exposed to the various pollutants than in the fish control. The comparatively low toxicity noticed within the sample fish was attributed to the reduced length o exposure to the pollutants this probably lowered the pressure of the toxicant on organs of the fish.
