Abstract Aquatic ecosystems are very sensitive to heavy metal pollutants and the gradual increase in the level of such metals in aquatic environment, mainly due to anthropogenic sources, became a problem of primary concern. The continuous exposure of metals can lead to hematological and biochemical disorders. In the developing countries, there was a great increase in the establishment of industries. Heavy metals are regarded as serious pollutants of the aquatic ecosystem because of their environmental persistence and their ability to be concentrated by aquatic organisms. The concentrations of certain heavy metals are extremely toxic to fish life in fresh water and it is suggested that heavy metals produce blood cell destruction. The concentrations of certain heavy metals are extremely toxic to fish life in fresh water and it is suggested that heavy metals produce blood cell destruction. Heavy metals produce and acute hematology crisis in aquatic organisms and pollutants generally caused rapid changes in blood parameters of fishes. Rohu (Labeo rohita) is the most important among the three Indian major carp species used in carp polyculture systems. This graceful Indo-Gangetic riverine species is the natural inhabitant of the riverine system of India.
