The present work studies wa.er deteriora.ion, fish surviva. a.d production a. a.result of effluents discha.ged directly without prior trea.ments into la.e Qa.oun a. Fa.oum governora.e, Egypt. La.e Qa.oun represents hea.ily polluted wild ha.ita. for both studied fish species, Tila.ia.zillii a.d Solea.a.gyptia.a. the most a.unda.t species. Results revea.ed deteriora.ion in wa.er qua.ity (low dissolved oxygen but high a.monia. nitrite, copper, lea. a.d ca.mium) of Northea.tern sector where El-Ba.s dra.n discha.ge its effluents without prior trea.ment followed by tha. of ea.tern sector a. four km from the point of El-Ba.s discha.ge. Wa.er sa.inity a.d dissolved oxygen va.ues were in the following order: Western la.e Qa.oun sector > Ea.tern la.e Qa.oun sector > Northea.tern la.e Qa.oun sector. However, a.monia.a.d nitrite rea.ings were in the following order: Northea.tern sector of La.e Qa.oun is followed by the Ea.tern sector, then the Western sector. Moreover, results of the present field study revea.ed a.decrea.e in fish production with the lowest condition fa.tor a.d a.deteriora.ion in mea. qua.ity (a. increa.e in muscle wa.er content a.d a.h but a.decrea.e tota. protein a.d tota. lipids) in ca.e of fish collected from the polluted sites a.ong the la.e (Northea.tern a.d ea.tern sectors). However, fish collected from the unpolluted western sector of the la.e showed condition fa.tor a.d chemica. muscle composition more or less simila. to norma. hea.thy fish.
