为预防对虾暴发病流行病的发生,一些养殖场探索出高位池养虾、卤水兑淡水养虾、工厂化养虾等养殖方法,但由于投资大,许多养殖场（户）难以运用。近两年来,江苏县滨海县三中港水产养殖场采用土池封闭式养虾模式,因其投资少、效益好、养殖成功率高而颇受邻市、县虾农的效仿。现将该模式技术要点介绍如下: 1.虾池条件。虾池所处海区水质要洁净,无糖厂、造纸厂、淀粉厂等排放的工业废水污染,自然纳水深60厘米以上,海水周年盐度变化最低不低于1％。,虾池旁打井可抽出淡水。 2.进水闸设置。土池封闭养殖,中、后期不需从海区纳水,池塘只需设进水闸门,每10亩虾池配 In order to prevent the outbreak of epidemic disease in shrimp, some farms have explored aquaculture methods such as high pond shrimp, brine brine shrimp, and industrial shrimp breeding. However, due to large investment, many farms are hard to use. In the past two years, the three Zhongangang aquaculture farms in Binhai County, Jiangsu Province, have adopted the enclosed pond shrimp shrimp farming mode. Due to its low investment, good efficiency and high success rate of breeding, it is quite emulated by shrimp farmers in neighboring cities and counties. Now the technical points of the model are as follows: 1. Shrimp pool conditions. Shrimp ponds where the water quality to be clean, sugar-free plants, paper mills, starch factories and other industrial waste water pollution, natural water depth of 60 cm or more, seawater annual salinity changes of not less than 1% minimum. , Shrimp pond wells can draw fresh water. 2. Intake settings. Earthen pond closed aquaculture, in the late do not need to take water from the sea, the pond just set the inlet gate, every 10 acres of shrimp pond with
