Abstract
The effect of sub- lethal concentrations of copper sulphate (2 mg/1 and 5 mg/1) on various biochemical parameters during different time periods i.e. 30, 60 and 90 days on Cyprinus carpio were studied. Serum albumin, serum globulin and serum total protein showed an overall decrease in all the copper sulphate treated groups throughout the experimental investigations with marked significant values.
