The present study was conducted on different sites of River Indus to find out the concentration and accumulation of heavy metals; Lead and Cadmium in gills, swim bladder and muscles of Rohu. The fish were collected from three different sites Topi, Hund and Kund of River Indus at Swabi, KPK Pakistan in the month of February, March, and April 2016 respectively. Results led to the conclusion that the accumulation of heavy metals in the month of February in gills were in order Pb (0.05 ppm)>Cd (0.04 ppm) Swim Bladder Pb (0.02 ppm)>Cd (N.D) and Muscle Pb (0.03 ppm)>Cd (N.D) respectively. The overall accumulation of heavy metals in Rohu in month of March in Gills were in order Pb (0.04 ppm)>Cd (0.01 ppm) Swim Bladder Pb (0.02 ppm)Cd (0.01 ppm) respectively. The overall accumulation of heavy metals in Rohu in month of April was in Swim Bladder Pb (0.01 ppm)
