In the industrialization era, pollution has deteriorated the living conditions of aquatic life leading to a steep deterioration in their quality and diversity. Industries discharge their waste containing heavy metals into the water bodies. These heavy metals accumulate in different organs of the fish, causing mortality. The effect first appears in blood and affects the fish by alteration of blood components making the fish weak, anemic and vulnerable to diseases. Heavy metal pollution thus targets fish which is one of the major protein source for human population. Such exposure to heavy metals cause increase or decrease in hematological indices of the fish coupled with decline in protein and glycogen reserves. Hence this study has been focused on the impact of heavy metals on fish Labeorohita. Heavy metals affect the reticulo endothelial system and haematopoisis, changing osmotic resistance of erythrocytes. The red and white blood cells at different stages of the pathological process are subjected to quantitative and qualitative deformation.
