两种微藻改善虾池环境增强凡纳对虾抗病力的研究

人工引入波吉卵囊藻和微绿球藻于凡纳对虾养殖环境中，检测与凡纳对虾抗病力有关因子变化和测定主要水质因子，研究微藻生态调控对凡纳对虾抗病力的影响。结果表明，引入波吉卵囊藻和微绿球藻能改善养殖水体的水质，凡纳对虾的血细胞数目，血清蛋白的含量以及酚氧化酶、超氧化物歧化酶，溶菌酶，抗菌酶的活性都较对照组显提高。因此，微藻生态调控是防止对虾疾病的重要技术措施。

STUDIES ON TWO MICROALGAE IMPROVING ENVIRONMENT OF SHRIMP POND AND STRENGTHENING ANTI-DISEASE ABILITY OF PENAEUS VANNAMEI

By means of artificial introduction Oocystis borgei and Nannochloris oculata into the cultural environment of shrimp, Penaeus vannamei, then inspecting the changes of factors that relate to the anti-disease ability of shrimp and measuring the main water quality factors to study the influence of microalage micro-ecology control over the anti-disease ability of shrimp. The result shows: Introducing Oocystis borgei and Nannochloris oculata into cultural environment can improve the water quality. The number of blood cell, the content of blood serum protein and the activity of phenoloxidase, superoxide dismutase(SOD), antibacterial enzyme and lysozyme are dramatically improved in contrast to the control group. Microalage-ecology control is an important measure to prevent the shrimp disease.
