Abstract:Mercury cycling in the environment is increasing due to its increased uses in industrial activities. Mercury chloride in water is absorbed by fishes. By eating infected fishes mercury is absorbed by human body which may result in death. The present investigation aimed to determine the protective role of ascorbic acid in diet to counteract the effects of mercury chloride.The experiment was set in 3 groups.Gambusiaafffinis were exposed to mercury chloride and 0.5% of vitamin C supplemented in diet.Experiment was carried for 90 days and then fishes were restored to control water conditions for 30 days. The general feeding behaviour,morphological survival and growth were studied. The histopathological changes in ovary showed necrotic,degeneration in oocytes. The result shows that the negative effects of mercury was neutralized by vitamin C diet.
