Abstract: Polluted water inhabitant fishes accumulate metals in their body tissues;mainly accumulation depends upon different factors, like way of uptake, temperature, time of exposure etc. Different metals show different affinities to fish tissues for accumulation. Liver and kidney have relatively high metal accumulation as compare to muscles.The present study was carried out to determine the bioaccumulation of heavy metals into different organs of fish collected from four sampling stations of river Jhelum. Three metals Cu, Pb and Mn were examined by using Shimadzu AA 6200 atomic absorption spectrophotometry and the results were as ug/g dry wt. Seasonal variations regarding metal accumulation in kidney, liver and muscles of edible fishes from river Jhelum was also observed. We observed that seasonal variations affect the bioaccumulation of metals in body tissues. Cu, Pb and Mn were higher in summer season as compared to winter season in kidney of fishes. But in the case of liver concentration had opposite affects and had highest concentrations of these metals during winter. While in muscles Cu was significantly (P<0.01) higher in summer,Pb was non significantly higher in summer and Mn was non significantly higher in winter in the case of muscles.
