Abstract: Presence of heavy metals adversely affects the health of the ecosystem. It is a matter of concern causing a threat to the life of organisms that are dependent on them. Heavy metals are resistant to degradation and their presence is toxic in various ways. They tend to bioaccumulate in organisms and show Biomagnification when consumed by organisms of the next trophic level. Heavy metal toxicity is now happening at alarming rates and needs to be addressed on a priority basis. The present study is a systematic review on the Bioaccumulation of Zinc (Zn) in freshwater fish Clarias batrachus (walking catfish). The idea is to figure out how the accumulation of Zn in different organs of fish impacts their morphology and behaviour. The aforementioned study will be conducted by taking the fish sample from the local market of the Patna region. The physico-chemical characterization of the water was performed in accordance with the standard protocol and the APHA regulations. The control tank and the treatment tank composed of water, fish and zinc in different quantities should also be installed in accordance with the standard experimental model. We found that the concentration of zinc in the treated groups increases as the dose and duration of treatment in water increases over a period of 15, 30, and 45 days. Present study revealed that the kidney and liver are the prime sites of zinc accumulation whereas the concentration of zinc load within the muscles was founded to be low as compared to other organs. Thus, both bioaccumulation and elimination of zinc were dose and duration dependent. This demonstrates the exposure and effects of heavy metals zinc in fishes also its consequential impact in the future. In this review, we have summarized the results of recent bioaccumulation of zinc studies on magur fish.
