Evaluation of Activities of Transferases and Phosphatase in Plasma and Organs of Clarias gariepinus Exposed to Fluazifop-p-Butyl

The aim of this study was to evaluate the activities of transferases and phosphotase in plasma, liver and kidney of Clarias gariepinus. This study was carried out in the department of fisheries and animal science, Niger Delta University, Wilberforce Island, Bayelsa State, between September, 2014 and April 2015. Adult Clarias gariepinus were exposed in four replicates to varying concentrations of fluazifop-p-butyl (ranging from 0.01 -0.03ppm) in a 30 day semi static bioassay. Samples were obtained from the liver, kidney and plasma. A statistically significant increase (p<0.05) was recorded in the plasma. Liver alkaline amino transferase (ALT) and Alkaline phosphatase (ALP) unveiled a significance decrease, while liver aspartate amino transferase (AST) showed a clear progressive increase compared to the control. Kidney enzyme values were significant. A progressive decrease in value were recorded (not in a dose dependent pattern). This toxicant could be toxic at high concentration. These parameters could serve as useful biomarkers of sublethal effect of fluazifop-p-butyl in non-target organism in the aquatic environment
