Environmental pollutants have hazardous impact on living organism present on this planet. Environmental pollutants give bad impact on the health of livestock as well as human beings and have been categorized as heavy metals, pesticides etc. Cadmium and its compounds are most common environmental toxicants with potential for bioaccumulation and persistence in the body, and produce versatile biotic changes in the aquatic ecosystem. Monitoring toxic metal level in aquatic ecosystem (especially fish) is the need of the awareness from public health point of view. It concluded that our fishes also carry good quantity of cadmium. It is inferred from the study that selective removal of tissues that accumulate highest levels of cadmium i.e. kidney and liver might reduce the chances of toxicity due to this metal in human consumers and in animals fed with fish-meal.
