Effect of Heavy Metal Pollution on Survival and Protein Changes in Liver and Intestine of Fresh Water Fish Tilapia mossambica
The heavy metal salts constitute a very serious type of pollution because they are stable compounds and are not readily removed by oxidation, participations or other means and affect the activity of animals. The toxicity of Hg, Cd, Zn and their compound to fish has received the attention of a number of workers in recent years. In the present study, it is observed that contents of protein decreased gradually with an increase in concentrations of metals and damage of respiratory surface.
