Abstract

Toxicity testing of chemicals on terrestrial and aquatic organisms has been used for a long time to detect the potential hazards posed by chemicals to the environment. This study investigated the effects of sub-lethal concentrations of glyphosate on the proximate composition and accumulation in the muscle tissue of Clarias gariepinus. Fish were exposed to four concentrations of glyphosate (0.00, 0.02, 0.03, and 0.04 mg/L) for 90 days. The physico-chemical parameters monitored were temperature, pH, dissolved oxygen, and electrical conductivity. Thermometers, pH meters, dissolved oxygen meters, and electrical conductivity meters were respectively employed during the study. Results showed that glyphosate exposure significantly altered the proximate composition of fish muscle, including moisture, protein, lipid, ash, fiber, and carbohydrate content. Glyphosate accumulation in fish muscle was also found to be dose-dependent, with higher concentrations of glyphosate resulting in greater accumulation. These findings suggest that exposure to sub-lethal concentrations of glyphosate can have negative impacts on fish health and nutritional quality, with potential implications for human consumption.
