Abstract
Industrial, domestic and other human activities are responsible for heavy metal toxicity of aquatic bodies. Metals are the major stimulators for variety of diseases in aquatic organisms mainly fishes. Chromium (Cr), mercury (Hg), nickel (Ni) and cadmium (Cd) causes histopathological variations and several diseases in various fishes of Pakistan. Extensive
histopathological variations in gills, liver, kidney and skin of different fishes were noticed when exposed to heavy metals, thus indicating severity of heavy metal toxicity. The current study was focused on the toxicological effect of Cr, Hg, Ni and Cd in different type of fishes and it would be useful for the scientific community to restore different metals contaminating water.
