摘要
针对中国对虾育苗用水处理关键技术,结合育苗生产单位实际条件,设计3种不同育苗用水处理模式:(1)天然海水三级沉淀净化(简称肥水),(2)沉淀海水再消毒砂滤净化(简称清水),(3)高盐水兑淡水,应用产卵高峰同批优质受精卵开展育苗对比实验研究。结果表明:清水育苗效果最好,肥水育苗效果其次,高盐水兑淡水育苗效果最差。为中国对虾育苗生产提供了源水处理技术和方法。
Against the key water treatment technology of breeding in Chinese shrimp,the article combining with the actual conditions of nursery manufactory designed three types of water treatment modes which were used in shrimp breeding：（1） The natural seawater via purification of three depositions（Rich water）（2） High-salt water diluted with fresh water（3） Precipitation seawater then sterilized and sand filter cleaning（Sterilized sand filter water）.The same batch of high-quality zygotes were used in this comparative experimental of seedling,the results showed： Sterilized sand filter water breeding the best,followed by Rich water,the effect of high-salt diluted with fresh water breeding worst.The research provided the technology and methods of water treatment in Chinese shrimp breeding.
