The effects of coastal water pollution of the Black Sea on the blood biomarkers of the round goby Neogobius melanostomus Pallas, 1811 (Perciformes: Gobiidae)

Abstract

The activities of antioxidant enzymes and the contents of the oxidized forms of the proteins in the blood of the Black Sea round goby Neogobius melanostomus, which were sampled in the waters of Sevastopol in 2003 and 2012, were studied. An increase in the values of the tested biomarkers in fish catches of 2012 compared to those of 2003 was recorded. The causes for the observed changes are discussed.
