Aquatic ecosystem pollution by heavy metals is a worldwide concern. Heavy metals have the ability to bioaccumulate in aquatic organisms, particularly fish, which is a source of livelihood for humans. Between March 2012 and February 2014, we assessed heavy metal (Cu, Cr, Pb, Ni, Zn and Cd) contamination in two food fish species (Labeo rohitaand Hypophthalmichthys molitrix) selected from Bhagwanpur fish pond in Roorkee, Haridwar, India. After acid digestion, the dried samples of fish tissues were analyzed for heavy metal concentrations by using atomic absorption spectrophotometery. Data obtained was analyzed using two way analysis of variance and Pearson’s correlation coefficient. The mean absorption of metals in different organs of L. rohita and H. molitrixranged from 5.754±2.591-56.851±12.569 μg g–1 dry weight and from 5.455±3.651-53.625±11.432 μg g–1 dry weight, respectively.
