Toxic effects of copper and zinc mixtures on some haematological and biochemical parameters in common carp, Cyprinus carpio (Linn).
The effect of heavy metals and mixture were studied on some haematological and biochemical parameters in fish, Cyprinus carpio at sublethal level over the period of 30 days. Heavy metal significantly decreased total RBC count, haemogoblin, heamatocrit (Hct) (except copper after 10 days exposure). The WBC count was increased significantly in all the treated fish. The MCH, MCHC, MVC were increased depending upon the exposure period; declined PVC was noticed at 1% level of significance after 30 days on all the treated fish. Serum level of chloride and calcium content were increased where as serum glucose, cholesterol and total serum protein were decreased significantly. The alteration in haematological and biochemical parameters shows more toxic in mixture after 30 days, showed more than 'addition action' of the individual toxicant.
