三级高位池半循环水生态精养对虾模式是将对虾养殖池设计成第一级(小)池、第二级(中)池和第三级(大)池3个不同面积的集约化养殖方式,在每级池中养殖1个月左右,转入下一级池,在整个养殖周期内,只添加淡水,进行半循环养殖,只依靠有益细菌降解池中污物,调节水质,因此,该模式具有成本低,效益好,污染病害少等特点,是一种值得推广的养殖模式。
Three-level high-pool semi-cycle aquatic eco-intensive shrimp model is designed shrimp ponds into the first (small) pool, the second (middle) pool and the third (large) pool three different areas of intensive farming Way, at each level of pond farming for about 1 month, transferred to the next pool, the entire breeding cycle, only add fresh water, semi-circular farming, relying on beneficial bacteria to degrade the pool of sewage, regulating water quality, therefore, The model has the characteristics of low cost, good efficiency and less pollution and disease, which is a kind of breeding mode worth promoting.
