Abstract

This investigation was designed to evaluate reproductive impairment of tilapia (as a bioindicator organism), inhabiting three sites in Lake Mariut which varied in nature and degree of physicochemical and organic criteria. It is concerned with monitoring bioaccumulation of metal in sperms of Oreochromis niloticus using SEM-X-ray microanalysis and illustrating concomitant ultrastructure sperm abnormalities. Fish caught from polluted sites exhibited a higher proportion of heavy metals, in particular Cu, Zn and Hg, than in reference site. Morphologically, sperms of O. ...
