摘要
１９９０～１９９３年试验使用副溶血弧菌及溶藻弧菌感染获得成功。在试 验过程中发现，环境及对虾体质对对虾感染死亡率影响甚大，恶劣环境中的死亡率 比优良环境中的死亡率高出 ８３．３％；体质差的对虾感染后的 ２４ｈ死亡率是正常对 虾的２．５～３倍。为此，在对虾养殖生产中除应注意消灭病原菌外，还应注意优化养 殖环境与增强对虾体质的问题。
The prawn red appendages disease is caused by some infecting vibrio or bacillus. The experiment we conducted on the infection of the prawn with Vibrio parahaemolylicus and Vibrio alginolyticus as proved successful. We found that the enviroment and constitution of the prawn had a great influence on the mortality of the prawn infected. Which is 83. 3% more in edverse environment than that in favorable environment. After infection, the mortality of the prawn with a poor constitution is 2. 5 to 3 times that of the normal ones within 24 hours. Therefore, in the course of production of farming prawn, the problem of improving culture environment and building up constitution of the prawn must be solved in addition to sterilizing germ.
