HISTOPATHOLOGICAL LESIONS IN TISSUES OF THE FINGERLINGS OF MULLET (MUGIL SEHELI) EXPOSED TO INDUSTRIAL DISCHARGES IN SUEZ BAY

Amal A. El-Daly Nasr El-Din M. Mahmoud (Late).

Abstract
The present work studied the histopathological alterations of the gills, liver and intestine of fingerlings of the Mugil seheli living in Suez Bay that receives discharges of mixed contaminants from four industrial sites; North drain of plant fertilizer unit, South drain of plant fertilizer unit, Misr-Iran of textile unit and slaughter-house and Ataqa power station. The characteristics of wastewater quality vary from one drain to another according to the chemicals used in the industry operation. The tissues lesions were detected microscopically after exposure to sublethal concentrations of these effluents for 48 hrs and 96hrs. The gills, liver and intestine of both control as well as exposed fishes were prepared for H&E staining. Gills lamellae revealed separation of squamous epithelium and fusion due to hyperplasia of both chloride and epithelial mucous cells. Hydropic and fatty degenerations were observed in the liver especially after 96 hrs of exposure. The intestine exhibited severe lesions as loss of brush border, hyperplasia of mucous cells and dilation of intestinal villii. From this study, it can be concluded that the stress of chemical pollutants of effluents have harmful effects on fish life as it destroyed the most vital organs. Therefore, such effluents must be subjected to sanitary treatments to be less harmful.

Key words: Mugil seheli fingerlings, Histopathology, Gills, Liver, Intestine
