Effect Of Manganese Chloride (Mncl2) On Peroxidase Activity In Labeo Rohita, Nadia Altaf, Muhammad Javed, Sidra Abbas

Journal of Bioresource Management

Four groups (n=10) of one year old Labeo rohita were exposed to 96-hr LC50 and sub-lethal (2/3rd, 1/4th and 1/5th) concentrations of MnCl2 for a duration of 30 days in the glass aquaria of 50L water capacity. After an exposure period of 30 days, the activity of peroxidase enzyme in the liver and brain of MnCl2 exposed fish was measured and compared with the control group. Physico-chemical parameters of the test media, viz. pH, dissolved oxygen, carbon dioxide, total ammonia, total hardness, calcium and magnesium were also monitored on a 12 hour basis during the whole experimental duration by following …
