Abstract

The present study was conducted to observed bioaccumulation of heavy metals such as lead and cadmium in gills, swim bladder and muscles tissues of Tor putitora collected from three different locations of River Indus that were Batakra, Ghazi and Kund in District Swabi, Khyber Pakhtunkhwa Pakistan. Present study was conducted from February to April 2016. Fish samples were collected from Batakra in February, from Ghazi in March and from Kund in April. Accumulation of heavy metal in fish sample collected from Batakra in February was in order like Lead (Pb) (0.03ppm) > Cadmium (Cd) (0.02ppm) in gills tissue followed by Pb (0.02ppm) > Cd not detected (N.D) in muscle tissue followed by swim bladder tissue having no accumulation of Pb and Cd. Likewise accumulation of heavy metals in fish sample collected from Ghazi in March was in order like Pb (0.02ppm) > Cd (0.01ppm) in gills tissue followed by Pb (0.02ppm) > Cd (N.D) in swim bladder tissue while Pb and Cd (N.D) in muscle tissues. Similarly accumulation of heavy metals in fish sample collected from Kund in April was in order like Pb (0.03ppm) > Cd (0.02ppm) in gills tissue followed by Cd (0.01ppm) > Pb (N.D) in swim bladder tissue while Pb and Cd (N.D) in muscle tissue. The result indicates that the bioaccumulation of heavy metals definitely affects the aquatic life of freshwater fish mahseer (Tor putitora) and scientific method detoxification is essential to improve the life of these fishes.
