Abstract
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; Clarias gariepinus 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. Higher bioaccumulation
of the studied heavy metals in gills, liver, kidney and muscles of Clarias gariepinus collected from the main drains significant increase in serum glucose,
liver and kidney functions, disturbance in protein profile of fish collected
from the studied main drains than that of fish collected from the river Nile
branch, El-Lahon that showed more or less normal values. Moreover, histopathological alterations in gills, liver, kidneys and clear DNA strand breaks in
fish liver cells increased statistically in Clarias gariepinus collected from ElFayoum drainage canals. Generally, the results highlights on the importance
of taking action through the responsible authorities towards quality of the
drainage water that fed fish farms by law that could play a role as a main
source of protein for human beings.
