The biochemical, physiological analysis and the genetical studies
for (Oreochromis niloticus, Oreochromis aureus and Clarius
gariepinus) from Abbassa, Manzala, Altal-Alkaber, Shader Azam and
Borolos in Egypt. The pollution of zinc, copper and nitrite was
increased in water and fish organs at Altal Alkaber. Lead and iron
increased in water and fish organs at Shader Azam and Manzala. The
pollution decreased in Abbassa and Borolos. The heavy metals
increased in liver more than gills and muscles. R.B.Cs, Hb, P.C.V
and activity of ALT & AST and Liver glycogen decreased in
Manzalla. Plasma total protein increased in fish of Shader Azam.
Total lipids in Oreochromis niloticus and Oreochromis aureus
increased in Manzala. Urea and creatinine increased in Oreochromis
aureus from Altal Alkaber. The induction of aberrant cells
increased in the three species collected from five locations except
Abbassa (O. niloticus, O. aureus), but the aberrant cells from gill
filaments of Clarias gariepinus were increased in Manzalla and
Shader Azam. We concluded that water pollutants have had an affect
on biochemical, physiological and genotoxic effect on the
properties of fishes exposed to it.
