| The aim of this work was to study the effects of sub-lethal exposure of lead acetate on the histopathology of the gills, liver, kidney and muscle and its accumulation in these organs of Clarias gariepinus. Results showed that lead accumulation in the tissues of C. gariepinus was dependent on the exposure period and lead concentration. Gills and liver were the predominant storage tissue and the order of accumulation in tissues was gill > liver > kidney > muscle. Some structural changes were observed in different organs, especially in the gills of the fishes exposed to lead acetate. Epithelial hypertrophy and epithelial lifting were apparent in the gills of exposed fishes. The degeneration of cytoplasm and secondary lamellae was also observed.... |

| ABSTRACT: The present study was aimed to evaluate the effect of heavy metals on an important tissue of two fish species Cyprinus carpio and Wallago attu, sampled from the Indus river, Mianwali District, Pakistan. The concentration of selected heavy metals Fe, Cr, Cu, and in gills, muscles, kidney and liver was compared with an International standard of food fish. The overall metal concentrations among different weight categories in C. carpio were in the order of Fe > Cu > Cr >. In W. attu the overall accumulation of these metals were, in order of Fe > Cu > Cr > Pb The order of accumulation of metals in gills and muscle of C. carpio was Fe > Cr > Pb > Cu; kidney and muscles of W. attu was Fe > Cr > Cu > Pb; liver Fe >... |
