Aquatic animals can be used to simulate toxicological tests in the lab. Heavy metals include lead, 
mercury, cadmium, chromium, copper, zinc, manganese, nickel, and silver. The effects of mercuric chloride 
on the oxidative stress and hemato-biochemical processes of Catla catla fingerlings have been assessed in this 
study. Catla catla species' bioaccumulation of mercury has detrimental effects and upsets ecosystems. 
Carbohydrate, protein, and fat levels were significantly lower in Catla catla fingerlings exposed to high 
environmental contamination. Mercury chloride changed a number of haematological markers. Catla catla 
treated to mercuric chloride showed hematological changes, indicating the toxicity of mercury. MDA, GSH, 
and antioxidant enzymes such as CAT, SOD, and GPx were used to assess oxidative stress in mercuric 
chloride exposed to Catla catla. Changes in oxidative stress markers brought on by mercury chloride toxicants 
demonstrated physiological stress. Mercury chloride is extremely harmful to catla catla. According to 
biochemical and oxidative stress markers, fish in acidified soft waters are more susceptible to mercuric 
chloride damage. Changes in blood, oxidative state, and biochemistry are possible indicators of pollution.
