ABSTRACT

 

The present study has been conducted on the effect of cobalt sulphate on fish Labeo rohita. Harmful metallic pollutants like mercury, cobalt, lead, zinc, cadmium, copper and nickel are known to cause undesirable changes in the physiological parameters (amino acids) of the fish exposed to them. These problems becomes still more complex due to these heavy metal pollutants being water soluble strong oxidizing agents, being non-degradable and are strongly bonded to many biochemical, especially polypeptides and proteins. Cobalt salt cobalt sulphate is used widely in industry. The gills of the fish are covered with mucous and turn dark in colour due to cobalt salts which are one of the main constituents of the industrial effluents reaching the water bodies. It has been observed that as duration of exposure increases the number of amino acids decreases or their quality is affected. Out of the amino acids proline, aspartic acid, glycine and leucine present in control fish, few were missing at higher concentrations.
