ABSTRACT
The present study aimed to assessment the quality of ejj7uent of Trust
Textile Factory which discharges its effluent in the western Side ofthe Suez
Bay (northertz part of the Gulf of Suez), [md its effects on fingerlings of
marine fish, lvfurzil seheli. Physicochemical conditions, nutrient salts and
metals concentrations were determined in the effluent before and after mixing
with seawater, high levels ofmost ofthe studied parameters were recorded.
The rcso of raw ejj7uent to fingerlings offish MUgil seheli were 13.3, 8.4
and 7. 2 % for 24, 48 and 72 hours, respectively. Different concentrations of
ejj7uents had a dClnlage effect on ovary, liver, gills and kidney. These effects
were representing in loose ofovary wall, rdegenerations ofoogonia and their
divisions. Also some early and late perinucleolus oocytes become atretic.
More hazardous effects were recorrdedfor other organs offish.
