Accumulation of heavy metals and feeding habits in Cyprinidae fishes of water bodies of Khuzdar, Balochistan, Pakistan

The research area is at Khuzdar district, we evaluate heavy metals concentration in water bodies and fish organs cyprinid fish (Cyprinus carpio,Cirinus mirigla,Tor putitora, Labeorohuta and Catlacatla). We discuss the water quality, physio-chemical changes and nutritional behavior of fishes. The heavy metals i.e. Fe, Cd, Pb, and Cr were identified by Atomic Absorption Spectroscopy (AAS) method. Metal concentration similar as well varied over four stations such, Zedi, Wangoo, Mola Chtook, and Wadh Poralli. Metals absorption followed the order: Fe > Cr >Pb> Cd. Gills and liver showed comparatively highest heavy metals concentration. Consequently, all cyprinid fishes presented statically important variations in all organs. Gut analysis of C.mirigla, gut examination by preponderance grade by volume of food content green algae, detritus, earth worm, mud, miscellaneous, phytoplankton, and zooplankton. L. rohita however, showed grade green algae, detritus, mud, earth worm, miscellaneous, zooplankton, and phytoplankton. C. carpiogreen algae, mud, detritus, miscellaneous, earth worm, phytoplankton, and zooplankton. T. putitora earth worm, green algae, mud, detritus, miscellaneous, phytoplankton, zooplankton, however in C. catla miscellaneous, mud, green algae, earth worm, detritus, phytoplankton, and zooplankton. The Fe concentration highest in all kinds of fishes, Cr showed Pb second highest accumulation two kinds, while Cd least in all fishes. Only Fe which is above the prescribed limit of WHO that can pose severe health risk to population of nation.
