摘要

<span style="font-family:;" "=""><span style="font-family:Verdana;">Increasing land reclamation in El-Fayoum governorate has led to increase the amount of drainage water that discharged without prior treatments to two main drains, El-Wadi and El-Bats drainages loaded by salts and heavy metals. So, the present investigation aims to evaluate quality of water samples collected from a branch of the river Nile (El-Lahon canal) and the main drains (El-Bats and El-Wadi) at Fayoum governorate on some biomarkers of the Nile catfish;</span><i><span style="font-family:Verdana;">Clarias gariepinus</span></i><span style="font-family:Verdana;"> inhabiting the studied degradable aquatic habitats. Water and nighty fish samples colleted from the different studied sites of collection by the help of fishermen for physicochemical analyes of water and fish biochemical analyses and histopathological alteration. Results revealed highly significant differences at P ≤ 0.01 with the highest water ammonia, nitrite, heavy metals (Cu, Zn, Pb and Cd) and lowest dissolved oxygen content accompanied by metals bioaccumulation in vital organs of fish collected from the main drains (El-Bats and El-Wadi) in comparision with that collected from the studied branch of the river Nile.

Moreover, histopathological alterations in gills, liver, kidneys and clear DNA strand breaks in fish liver cells increased statistically in </span><i><span style="font-family:Verdana;">Clarias gariepinus </span></i><span style="font-family:Verdana;">collected from El-</span></span><span style="font
