The present investigation was undertaken to evaluate the effect of sublethal concentrations (0.088 and 0.044 mg 1−1, i.e., 1/5th and 1/10th fraction of 96 h LC50) of mercuric chloride on Ca, inorganic phosphate, water content, ash, glycogen, Fe, total protein, lipid contents and vitamin A, C, D, and E of liver, muscles and ovary of the freshwater fish Notopterus notopterus exposed for 30 days. The results obtained indicate that Ca, inorganic phosphate, water, ash, glycogen, Fe, total protein contents and vitamin D decreased significantly or insignificantly in these tissues of the Hg exposed fishes. However, lipid content increased in liver and muscles, but decreased in the ovaries. Vitamin A and D increased in the liver but decreased in the muscles and ovaries. Moreover, vitamin E increased in all the tissues of the fish exposed to 0.088 mg 1−1 and decreased in the fish exposed to 0.044 mg 1−1 of Hg concentrations.
