Fish are the most important organisms used in biomonitoring of aquatic ecosystems. Parameters of oxidative stress in fish tissues represent significant biomarkers in the assessment of the status of environment. Specimens of hake (Merluccius merluccius L) and red mullet (Mullus barbatus L) were collected from the locality in front of sea-port Bar (South Adriatic Sea) at the end of May 2005. Activity of the enzymes of the antioxidative system (superoxide dismutase - SOD and catalase - CAT) and parameters of oxidative stress (lipid peroxidation - LP and reduced glutathione - GSH content) were determined in the liver of hake and red mullet. Obtained results showed that the activities of SOD and CAT were significantly lower in the liver of hake than in red mullet. Higher concentrations of LP and GSH in liver of hake were recorded, due to the changes of physical-chemical parameters of environment. The intensity of oxidative stress in liver of hake was higher in comparison to red mullet.
