Oxidative Stress in Round Goby Neogobius melanostomus Exposed to Different Water Salinities

The objective of this study was to evaluate oxidative stress in round goby exposed to different water salinities. Fish were exposed to three water salinities (0, 5 and 20 ppt) for 33 days. After exposure, fish were sacrificed and livers were sampled. Lipid peroxidation in the liver was assessed by measurement of thiobarbituric acid-reactive substances (TBARS). Our results showed large variation in peroxidation response among fish regardless of the water salinity. Fish exposed to a salinity of 5 ppt presented the highest lipid peroxidation level, whereas fish exposed to 20 ppt showed the lowest. These results indicate a strong influence of salinity on round goby lipid peroxidation.
