The measures on the prevention of Explosive Epidemic Disease of Cultured Shrimp

本文分析了1993年以来养殖对虾暴发性流行病传播途径和可能寄主的研究结果以及养虾群众的虾病防治经验,提出了以下主要防治措施: 1、养虾开始前彻底消灭虾池中可能存在的底栖甲壳类,养虾生产中切实防止池外虾蟹进入虾池。 2、对虾养殖池内引进一定数量的斑尾复(鱼段)虎鱼,消灭患病对虾和其他对虾暴发性流行病病原的可能寄主。 3、养虾过程中定期使用ClO_2消毒,控制虾池中有害微生物的数量。 在实施以上措施的同时,特别注意使用优质饲料,优化养殖环境。三年来,在近千亩左右虾池的实践中取得了较好的养虾业绩,最高单产150kg/亩。
