Abstract:

The aim of this study was to determine the effect of the pesticide, diazinon, on phosphatases in the plasma and organs on Clarias gariepinus. Adult Clarias gariepinus were exposed in four replicates to varying sublethal concentrations diazinon (ranging from 1.00 to 10.0 mg/L) in 30-day semi-static bioassays. Alkaline phoshatase (ALP) and acid phosphate (ACP) were determined in plasma and other organs (gastrointestinal tract - GIT, kidney, muscle, gill and liver) of the fish after the experimental exposures. Dizinon did not cause any statistically significant difference on plasma ALP over the concentrations tested (p>0.05), but ACP showed significantly higher mean value at 10 mg/L compared to the control. ALP and ACP values in all the organs (GIT, intestinal tract, kidney, muscle, gill, liver) decreased with increasing concentration of diazion. This indicates an evidence of inhibition of these enzymes in the organs by the toxicant, and therefore alteration of biochemical processes in C. gariepinus which can be used as bio-indicators of the effects of diazinon in the Niger Delta environment.
