由于地下卤水河蟹育苗技术起步晚，在生产应用中尚存在一些问题有待解决。其中铁离子对亲回和幼体的影响是很重要的一个方面。根据河蟹产卵及幼体生长发育要求，Fe2+、Fe3+含量最适范围为0．02～0．05mg／L，但地下由水中Fe2+Fe3+含量却存在着区域性和时间性的差异，有时由于Fe
Due to the underground brine crab breeding technology started late, there are some problems in the production and application to be solved. Among them, the effect of ferric ions on parental rearing and larvae is an important aspect. According to crab spawning and juvenile growth and development requirements, the optimum range of Fe2 +, Fe3 + content is 0.02 ~ 0.05mg / L, but there are regional and temporal differences in Fe2 + Fe3 + content in underground water, sometimes due to Fe
