【摘要】 以点篮子鱼(Siganus guttatus)幼鱼为研究对象,使用浒苔(Enteromorpha prolifra)和人工饲料分别饲喂点篮子幼鱼,试验周期90天,对比两饲料组幼鱼的血清生化指标和抗氧化酶活性。结果显示,浒苔组幼鱼的总蛋白(TP)、尿素氮(UN)和碱性磷酸酶(AKP)均显著高于人工饲料组(P<0.05),而谷草转氨酶(AST/GOT)和谷丙转氨酶(ALT/GPT)却显著的低于人工饲料组(P<0.05)。浒苔组幼鱼肝脏、肾脏、鳃、肌肉的超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GPX)、抗超氧阴离子自由基活性均高于人工饲料组;浒苔组肝脏中过氧化氢酶(CAT)和抑制羟自由基活性显著低于人工饲料组(P<0.05)。更多还原

【Abstract】 180 fish were divided into two diet groups(three cages of each group), and the fish was fed with E. prolifra and artificial feed respectively for 90 days. The results showed that the total protein(TP), urea nitrogen(UN) and alkaline phosphatase(AKP) of juvenile S. guttatus fed with E. Prolifra were significantly higher than that fed with artificial feed(P <0.05), while the glutamic oxalacetic transaminase(AST/GOT) and glutamic-pyruvic transaminase(ALT/GPT) of juvenile S. guttatus fed with E. Prolifra were significantly lower than that fed with artificial feed(P < 0.05). SOD, GPX and anti-superoxide anion radical activity in liver, kidney, gill and muscle of juvenile S. guttatus fed with E. Prolifra were higher than that fed with artificial feed, and these antioxidant enzyme activities in kidney of juvenile S. guttatus fed with E. Prolifra was significantly higher than that fed with artificial feed(P < 0.05), while CAT and inhibiting hydroxyl radical activity in liver of juvenile S. guttatus fed with artificial feed were significantly higher than that fed with E. Prolifra(P < 0.05). According to the result of the experiment, the juvenile S. guttatus fed with E. Prolifra showed better antioxidant defense system.更多还原
