近年来，锯缘青蟹养殖在浙江省得到了很大发展，养殖的水面主要集中在盐度适宜的潮间带水域。随着农业产业结构的调整，浙江省河口地区的众多低盐度水域急待开发，由于锯缘青蟹耐低盐能力较强，因此可作为低盐度池塘养殖的开发对象之一。本试验是为了探索出一套可在低盐度条件?
In recent years, serrata crab farming has been greatly developed in Zhejiang Province. The aquaculture water is mainly concentrated in the intertidal zone with salinity. With the adjustment of agricultural industrial structure, many low-salinity waters in the estuarine area of Zhejiang Province are urgently needed to be developed. Because of their ability to tolerate low salinity, scylla serrata can be used as one of the development targets for low salinity pond culture. This experiment is to explore a set of low salinity conditions?
