Freshwater is a chief natural resource used for various types of activities in our daily life i.e. for drinking as well as different developmental purposes. An increase in pollution level leads to instability in our natural environment and harm both the physical systems and living organisms dwelling in the ecosystem. Various harmful substances present in polluted water bodies in the form of insecticide, pesticides, heavy metals, mills waste, and crude oil are frequently released into the aquatic ecosystem. When a large amount of these pollutants is released into any water body, causes an acute effect by rapid highscale mortalities of aquatic organisms. Minor levels of pollutant discharge result in an accumulation of the contaminants in the body composition of fish species.
