Concentration of antioxidant compounds and lipid peroxidation in the liver and white muscle of hake (Merluccius merluccius L.) in the Adriatic sea

Abstract

Specimens of a marine freshwater fish - hake (Merluccius merluccius L.) - were collected at the localities of Platamuni and Valdanos (Montenegro, South Adriatic) in the spring of 2003. Our results showed higher concentrations of LPO, Vit C, and Vit E in the liver in comparison with white muscle. The concentration of LPOin both tissues was higher, while that of Vit E was lower at Valdanos compared to Platamuni. These differences in parameters of oxidative stress are partly due to differences in temperature and the concentrations of nitrites, nitrates, and detergents in the waters of Valdanos compared to Platamuni.
