A comparative study of long-term pollution effects of marine waters on the blood biomarkers of two benthic fish species: the scorpion fish Scorpaena porcus (Linnaeus, 1758) and the round goby Neogobius melanostomus (Pallas, 1814) from the Black Sea

Resumo

Blood antioxidant enzyme activities were studied in 2003 and 2012 in the scorpion fish Scorpaena porcus (Linnaeus, 1758) and the round goby Neogobius melanostomus (Pallas, 1814) caught in two Sevastopol bays with different pollution levels. The study revealed higher blood antioxidant enzyme activities in the fish caught in 2012 compared to 2003. Possible causes of these changes are discussed.
