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‰。2 进水闸设置由于是土池封闭式养殖,其中、后期不需从海区纳水,因此,池塘只需设进水闸即可。每10亩虾池配置宽1米的通天进水闸一座,闸室设三道闸槽,外槽安装滤杂网,中槽设闸板,每块闸板宽约20厘米,便于调节虾池水位,内槽安装锥形滤水密网。3 放苗前准备3.1 在虾池虾坝上打井,井的深度必须能满足虾池连续注水 1 shrimp pond conditions Shrimp pond where the water quality to be clean, sugar-free plants, paper mills, starch plants and other industrial waste water pollution, natural water depth of 60 cm or more, seawater annual salinity change of not less than 1 ‰ minimum. 2 Intake set Because it is a closed culture of earth pond, which does not need to be satisfied from the sea later, so the pond can be set into the sluice. Each 10 acres of shrimp pond configuration 1 meter wide Tongtian into a sluice, the sluice chamber set up three sluice slot, outside the trough to install the filter mesh, the trough set gate, each gate width of about 20 cm, easy to adjust shrimp pond water level , The cone installed cone filtration dense network. 3 Preparation of pre-emergence vaccine 3.1 shrimp pond dam on the well, the depth of the well must be able to meet the shrimp pond continuous water injection
