Heavy metals are widely used in every industrial application; therefore, they form the core group of pollutants of any industrial discharge. Some of the heavy metals such as Fe, Mn, Co, Ni, Cu, Zn and Cr are essential as they form the cofactor for many of the enzymes and also needed in metabolic activities. On the contrary, their exceeding amount is also detrimental to both animals and human beings. Increased pace of the industrialization and use of advance technologies for the quest of development leads to the problem of environmental pollution. One such condition has been witnessed in the present study in MIDC Area of Amravati region of Maharashtra India. Rapid industrialization results in the production of huge amounts of solid and/or liquid wastes, which is usually discharged into the nearby water bodies, leading to the damage of the important ecosystems and seafood products. Therefore, Investigations on the accumulation of heavy metals (Cu, Ni, Fe, Co, Mn, Cr and Zn) were carried out on Channa punctatus (murrel). The accumulation was observed in tissues of muscles, liver, kidney and gills. The results revealed that the Fe and Ni concentrations were the highest in all tissues analyzed, followed by Co, Zn, Cu and Cr. The present overview aims to highlight the issue of pollution of aquatic ecosystems and fish health around MIDC Amravati region Maharashtra. Based on the current review, it has been observed that to monitor the health of indicator organism (fish), battery of bioassays or biomarkers are required. The rationale of using the few selected parameters such as, marker enzymes of tissue damage, oxidative stress, genotoxicity and histopathology in describing, the aquatic pollution has also been emphasized. All these parameters are significantly affected by heavy metals and hence proved as useful tools in biomonitoring or toxicity assessment studies. Since fishes are consumed by large mass of population due to their high protein and polyunsaturated fatty acid content, human health is also under danger.
