ABSTRACT
Present study was carried out to evaluate the changes in organic reserves of kidney, liver, gill and muscles of Clarias batrachus exposed to sublethal concentrations of zinc sulphate in water for a period of 15,30 and 45 days. Four groups of twenty five fish were subjected to 0 (control), 10, 20 and 30 mg/L of zinc sulphate. The sub-chronic exposure of Clarias batrachus to sub-lethal concentration of Zinc sulphate showed a decline in glycogen, total proteins, cholesterol and total lipids in all these tissues. The levels of these organic reserves alter simultaneously with an increase in dose and duration of zinc exposure.

Key words : Biochemical changes, Clarias batrachus, Zinc.
