Based on the findings in the comparative study of immune parameters between Chinese shrimp Fenneropenaeus chinensis and Kuruma prawn Marsupenaeus japonicus, this thesis firstly carry on the researches of iNOS activity in shrimps, and find it a reliable parameter for indicating the disease resistance ability in shrimps. The results here could offer a sound scientific basis for the better understanding of the mechanism of shrimp disease resistance ability to WSSV infection, as well as the development of countermeasures for the disease control in shrimp culture industry.

本文在系统比较两种对虾感染WSSV病毒过程中抗病力指标变化的基础上，优选出与WSSV感染直接相关的抗病力指标，并首次对对虾的一氧化氮合成酶进行了系统的研究，所得到的结果为深入了解对虾对白班综合症病毒的抗病力机制，并建立和发展相应的病害防御措施提供了科学依据。

Furthermore, the iNOS was identified in the haemocytes of Chinese shrimp F. chinensis and Kuruma prawn M. japonicus, and the methods developed were employed to evaluate their immunocompetence to WSSV infection in shrimps.

在对现有文献进行全面综述的基础上，我们通过实验系统比较了中国对虾和日本对虾在摄食感染WSSV后的死亡率、免疫学因子和感染病毒的变化情况，以及在氨氮胁迫下对虾感染WSSV过程中免疫学因子的变化情况。

Chinensis and Kuruma prawn M. japonicus increased at 12 and 48 hours post-inoculum, but decreased sharply after 36 and 72 hours post-inoculum respectively. LPS inducible NOS activity also decreased significantly with the time elapsed in WSSV infected shrimps. Results of WSSV detection with the Dig-DNA Probe dot blot hybridization test showed that WSSV of the two penaeid species couldn't be detected until iNOS started decreasing.

在此基础上，我们建立了对虾血细胞中诱导型一氧化氮合成酶的鉴定方法—硝基四氮唑蓝还原法和血细胞形态法以及酶活力的测定方法—L-瓜氨酸分析法和亚硝酸盐分析法并优化了鉴定和测量条件，结果显示：对虾血细胞在4℃下与L-精氨酸和LPS孵育8h以及当L-精氨酸浓度为2.5mmol l〓LPS浓度为100μg ml〓，Ca〓浓度为2.5mmol l〓时，iNOS活力的测定结果最佳。

The experiments were conducted to find out the effects of calcium, copper, zinc, manganese ions, SDS and EDTA (ethylene diamine tetraacetic acid) on the superoxide dismutase in muscle of kuruma shrimp Penaeus japonicus, prawn Procambarus clarkii and Bacific white shrimp Litopenaeus vannamei and the differences in SOD in muscle, gill and hepatopancreas.

测定了Ca(上标 2+)、Cu(上标 2+)、Zn(上标 2+)、Mn(上标 2+)及SDS、EDTA不同浓度对日本对虾、克氏原鳌虾、凡纳滨对虾肌肉组织中超氧化物歧化酶活性的影响及其肌肉、鳃、肝胰腺组织中SOD活性的差异，并利用电泳技术研究了组织同工酶。

The influences of some metal ions in seawater treated by Cephlex 100 on metamorphosis, growth and activities of alkaline phosphatase and ATPase in mysis and postlarvae of Chinese prawn Penaeus chinensis were studied.

向经过螯合剂Cephlex 10 0处理的海水中添加金属离子，进行培养中国对虾糠虾幼体和仔虾幼体，观察金属离子对变态发育及其体内碱性磷酸酶和ATPase活性的影响。

The Antimicrobial effect of Coptis chinensis is strongest with biggest diameter (qb= 30.50mm) of bacteriostatic circle, while Sanguisorba officinalis are relatively effective against V.. parahaemolyticus (prawn pathogen of red body disease).

根据实验结果得出以下结论：(1)34种中草药的抑菌活性实验结果表明，共有4种中草药对本实验所选择的4种病原菌均有抑制作用，其中以黄连的抑菌作用最强，其抑菌圈的直径最大，达到30.50 mill。

The doctor said it was caused by sitotoxism. He warned people to pay more attention to diet hygiene and be cautious of bacterial food poisoning. The government should attach more importance to food safety management and supervision as well as canteen hygiene. It is forbidden to eat meat of sick animals or other bad food. You had better not eat wine prawn and salted shrimps; Chilled food should keep fresh; Animal meat and leftovers should be heated and boiled completely.

医生说这是食物中毒引起的，提醒我们要特别注意饮食卫生，谨防细菌性食物中毒事件的发生，要搞好食品安全管理、监督和食堂卫生，禁止食用病死禽畜肉或其他变质肉类，醉虾、腌蟹等最好不吃；冷藏食品应保质、保鲜，动物食品食前应彻底加热煮透，隔餐剩菜食前也应充分加热；烹调时要生熟分开，避免交叉污染；腌腊罐头食品，食前应煮沸6至10分钟；禁止食用毒蕈、河豚等有毒动植物。

The results showed that the value of the district was the highest, which is 2.6 × 10^7 yuan RMB, when the areas of the ecosystem and prawn pond are 25.4 km^2 and 9.6 km^2 respectively. And that is recommended that ideal Spartina alterniflora/ pond ratios should not exceed 27% of the ecosystem area converted to ponds.

研究结果里示，当互花来草盐沼生态系统面积为25.4平方公里、对虾养殖面积为9.6平方公里，即对互花米草盐沼生态系统的开发面积不超过其总面积的27%时，可实现该区域资源价值的最大化，其评估值最高，为2 626.7万元。

In the stage of prawn culture, twenty-three predator fishes were found. They are chiefly composed of such species as Portunus trituberculatus, Nibea albiflora, Eleutheronema tetradactylum, Lateolabrax japonicus, Triclentiger trigonocephalus.

对虾池内基础饵料种类和对虾养成期各阶段虾池及附近海域危害对虾敌害生物调查，目前未见详细报导。1983～1984年，我们在普陀朱家尖对虾养殖场和定海北蝉大成虾场进行了初步调查。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
