In the current study, an intraperitoneal injection containing the same concentration of MeHg and HgCl2 was administered in Hoplias malabaricus, after 96 hours fish were anesthetized and the muscle tissue were removed. A significant inhibition of the ChE was observed the fish exposed to MeHg, compared to control. The present work demonstrates that ChE is an effective biomarker in fish exposed via intraperitoneal injection to the organic forms of mercury.
