COPPER SULPHATE INDUCED HAEMATOLOGICAL AND BIOCHEMICAL ANOMALIES IN THE INDIAN CATFISH, HETEROPNEUSTES FOSSILIS (BL).

Effect of copper sulphate oncertain blood parameters of Heteropneustes fossilis was analysed. The R.B.C. number was reduced from 3.02 + 0.60 to 1.0 + 0.2 million/cu. mm after five days of copper sulphate stress. The total protein also reduced from 8.0+0.16 to 4.8+0.8 g/dl whereas W.B.C. number, haemoglobin, blood sugar, urea, seruncholesterol and bilirubin exhibited an elevation from control values. During recovery, the number of R.B.C. was quite low (1.95 it 0.1 million/cu.mm) and the total protein was 3.2 g/dl. The remaining parameterseven after 5 days of recovery exhibited sufficiently higher values than those of control.
