Abstract

A major source of contamination of the aquatic environment is from the leaching of chemicals used in industrial and farming processes. Farmers have greatly embraced the use of herbicides in the control of weed and glyphosate-based herbicides are usually the herbicide of choice widely popular. This project is to evaluate the changes in the concentration of nitric oxide in serum, gills, brain, liver, and kidney of clarias gariepinus exposed to glyphosate-based herbicides. Twenty (20) Clarias gariepinus divided into four groups (A, B, C, and D) i.e n  5 were used for this experiment. Group A was without herbicide exposure (control), groups B, C and D were exposed to 60mg/l, 80mg/l and 100mg/l of glyphosate respectively for 14days after which fish were sacrificed and biochemical analysis carried out. The results showed that the concentrations of nitric oxide as compared to the control increased significantly (p  0.05) in the gills, brain, liver, and kidney of  Clarias gariepinus. In conclusion, this study reveals that exposing Clarias gariepinus to glyphosate-based herbicides upset metabolic processes in the fish hence expressing toxicity and also implies poor environmental fitness for fish exposed to herbicides in the natural environment and thus, herbicide contamination in aquatic life should be curtailed.
