摘要: VELKOVA-JORDANOSKA, L., G. KOSTOSKI and B. JORDANOSKA, 2008.Antioxidative enzymes in fish as biochemical indicators of aquatic pollution. Bulg. J. Agric. Sci., 14: 235-237 Antioxidant enzyme activities (Barbus m. petenyi Heck.) were determined to establish possible environmental impact toxic effect on anthropogenic pollution Lake Ohrid. Activities superoxide dismutase (SOD) catalase (CAT) the blood chosen bioindicators. Fish sampled during May 2007 from locality Kalista (Lake Ohrid). After sacrificing fishes freshly samples collected transported ice. Superoxide activity was measured by ferricytochrome c method using xantine/ xantine oxidase a source radicals. Catalase determinated measuring decrease hydrogen peroxide concentration at 240 nm. have been proposed for monitoring land-based because they may concentrate indicative pollutants their tissue, directly water through respiration also diet. are frequently subjected prooxidant effects different often present environment.
