Water pollution is one of the serious problems that affect the marine ecosystem globally. Among all, high concentrations of the trace metal levels are severe threat to human health concern. Releases of heavy metal in the marine ecosystem are as byproducts and end products of industrialization which is consequent contamination of water ways created greater health hazards in aquatic organisms particularly fishes.A study was conducted between August 2010 to July 2011 to assess the accumulation of Cu, Co, Cr, Pb, Hg, Fe and Mn in gill tissue, gut content and muscles of selected commercially important food fishes Asian Seabass (Latescalcarifer) and Seer fish (Scomberomorusguttus) from Nizampatnam coast, Andhra Pradesh. In the present investigations the concentration of heavy metals in the gut content was significantly higher than that of gills, followed by muscle.The highest metal concentrations found in the organisms of fishes which leads to the oxidative stress shorten the lifespan of the fishes are postulated primary result from anthropogenic activities, shrimp pond effluents and sewage water and effluents from local industrial activities in the Nizampatnam coast.
