dc.descriptionAbstract: Trichlorfon (TCF) is an organophosphate parasiticide commonly used in aquaculture to treat ectoparasites. However, studies across various fish species have reported adverse effects even at sublethal doses. This study assessed the hematological and biochemical responses of Nile tilapia juveniles (Oreochromis niloticus) following a one-hour exposure to a 0.5 mg L⁻¹ bath of a commercial TCF-based product. It also evaluated the fish's physiological recovery 28 hours after exposure. Results showed elevated plasma cortisol levels and a downregulation of glutathione-S-transferase (GST) activity in liver tissue among TCF-exposed fish compared to controls. Alterations in the leukogram of treated fish indicate an increased vulnerability to disease. These findings suggest that a 28-hour recovery period is insufficient to restore the physiological health of Nile tilapia juveniles after TCF exposure. The study highlights the importance of adopting best management practices (BMPs) when applying TCF treatments in aquaculture and underscores the need for further research on the short- and long-term physiological impacts of chemical treatments on fish.
