%X The present work studies water deterioration, fish survival and
production as a result of effluents discharged directly without prior
treatments into lake Qaroun at Fayoum governorate, Egypt. Lake Qaroun
represents heavily polluted wild habitat for both studied fish species, <i><span style=\"font-family:Verdana;\">Tilapia
zillii</span></i><span style=\"font-family:Verdana;\"> and </span><i><span style=\"font-family:Verdana;\">Solea aegyptiaca</span></i><span style=\"font-family:Verdana;\">, the most abundant species. Results
revealed deterioration in water quality (low dissolved oxygen but high ammonia,
nitrite, copper, lead and cadmium) of Northeastern sector where El-Bats drain
discharge its effluents without prior treatment followed by that of eastern
sector at four km from the point of El-Bats discharge. Water salinity and
dissolved oxygen values were in the following order: Western lake Qaroun sector
&gt; Eastern lake Qaroun sector &gt; Northeastern lake Qaroun sector. However,
Ammonia and nitrite readings were in the following order: Northeastern sector
of Lake Qaroun is followed by the Eastern sector, then the Western sector.
Moreover, results of the present field study revealed a decrease in fish
production with the lowest condition factor and a deterioration in meat quality
(an increase in muscle water content and ash but a decrease total protein and
total lipids) in case of fish collected from the polluted sites along the lake
(Northeastern and eastern sectors).</span><b> </b><span style=\"font-family:Verdana;\">However, fish collected from the
unpolluted western sector of the lake showed condition factor and chemical
muscle composition more or less similar to normal healthy fish.</span>
