Abstract
Aquatic pollution by heavy metals is a growing concern that has been proved because of its detrimental effects on biological life, extremely toxic to fish and some aquatic arthropods, including human beings. The present study was undertaken in order to find out the toxicological effects of copper and mercury on the Trichopodus trichopterus from the habitats characterized by different environmental condition. The investigation has centred mainly to study the toxic effects of copper and mercury individually at different lethal levels on the gourami fish (Trichogaster trichopterus). The heavy metals are some of the most toxic compounds to aquatic organisms, and of these, mercury and copper are among the most toxic. Gourami fish exposed to CuS04, ZnSo4 and HgCl2 have shown more or less identical response. Various concentrations, 0.3, 0.6 and 0.9 of the toxicants were used to determine the taxological effect on the fish. During the present investigations, copper was found to be most toxic among copper, zinc & mercury to all the tested Gourami fish. Further study is recommended studying the processes by which these heavy metals affect physiology and histology of fish and their accumulation in fish tissues.
