南美白对虾引进我国后,发展迅速,形成了第二次养虾热潮,为水产品的结构调整、增加农民收入做出了显著贡献。尤其是它能在淡水中生活生长,且生长速度快于海水养殖,使其养殖面积产量得到迅速发展,作为“海产淡养”的新品种,在“淡化”过程中应注意以下几点: 1、选好的健康虾苗,应要求苗场进行5天左右的淡化,使盐度达4‰—5‰,个体达1.2cm左右,才可引到本地淡水养殖场。虾苗进池前,要先将暂养池的盐度调到4‰,可按每立方米水体施粗盐2—3kg的方法
After the introduction of P. vannamei, it developed rapidly and formed the second wave of shrimp cultivation, making a significant contribution to the structural adjustment of aquatic products and increasing farmers’ income. In particular, it can live and grow in freshwater, and its growth rate is faster than that of seawater aquaculture. As a result, its area of aquaculture production has been rapidly developed. As a new species of “marine breeding”, we should pay attention to the following points in the process of “desalination”: 1 , The selected healthy shrimp, seedlings should be required for about 5 days of desalination, the salinity of 4 ‰ -5 ‰, individuals up to about 1.2cm, before they can lead to the local freshwater farms. Shrimp into the pool before the first pond will be transferred to the salinity of 4 ‰, can be applied per cubic meter of water 2-3kg crude salt method
