Abstract
Fish are widely used as model organisms for the assessment of the quality of aquatic environment and can therefore serve as bio-indicators of environmental contamination. The current research investigates the eco-physiological damage to fishes in Suez Canal for enhancing the biomonitoring of this area through the biochemical investigation, were estimated in the gills, kidney and liver of Mullet, (Crenimugil crenilabis) from Suez Canal, Egypt. This area gets a lot of wastes discharged from several industries, and it is considered as the main routes of many tankers. Crenimugil crenilabis weigh up approximately 350-600 g were fished from Nabq Managed Resource Protected Area as a control area and Suez Canal as a polluted area. Compared with control, a significant changing in the biochemical analysis results, shows that there was an initiation of oxidative stress in the tissue of Mullet from the Suez Canal which indicating the contamination status of this area.
