测定了鲑鱼和鲟鱼不同组织(鳃、心脏、消化道、肝脏、白肌、皮肤、红细胞、游泳囊)的超氧化物歧化酶、过氧化氢酶、谷胱甘肽过氧化物酶、谷胱甘肽还原酶的活性和脂质过氧化作用。除过氧化氢酶外，鲑鱼的总组织抗氧化活性普遍高于鲟鱼，而肝脏则表现出相反的趋势。在这两个物种中，消化道中的脂质过氧化程度比其他组织中的要高。与鲑鱼相比，鲟鱼以脂肪的形式储存在肝脏和肌肉中的能量含量更高，因此似乎有一种有效的抗氧化保护措施，这表明脂质过氧化作用较低。
Enzymatic antioxidant activities (superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase) and lipid peroxidation were determined in different tissues (gills, heart, digestive tract, liver, white muscle, skin, red blood cells, swimbladder) of trout (Oncorhynchus mykiss) and sturgeon (Acipenser naccarii). Total tissue antioxidant activity was, except for catalase, generally higher in trout than sturgeon, with the reverse tendency displayed by the liver. In both species, lipid peroxidation in the digestive tract showed higher values compared to the other tissues. Sturgeon, compared to trout, had higher energy content stored as fat in liver and muscle and thus appeared to have an effective safeguard against oxidation, as shown by low lipid peroxidation.
