内陆河蟹育苗因深受沿海低成本育苗冲击,大眼幼体价格一路下跌。而成本除种蟹以外,作为主饵的丰年虫卵反而价格上升,这无疑是对内陆育苗的严峻考验。但沿海因缺乏纯淡水,大眼幼体无法彻底淡化,也无法进行纯淡水豆蟹培育。在低盐度水中培育的豆蟹,一般来说养成商品蟹时性成熟提前,规格偏小,有人认为低盐水中培育豆蟹肠道易发生折曲。而蟹苗向较远的内陆运输常常损耗较大。所以这就给内陆人工育苗生存留下了一席之地。内陆育苗还具有一些沿海无法取代的优势,比如当地育出的苗适应当地的水系。笔者 Inland crab breeding by the coastal low-cost nursery shocks, big octopus larvae prices all the way down. In addition to the cost of planting crabs, but as the main bait harvest eggs but the price increases, this is undoubtedly a severe test of inland nursery. However, due to the lack of pure fresh water in the coastal area, the larvae can not completely desalinate, nor can they cultivate pure freshwater crabs. Bean crabs cultivated in low-salinity water generally develop earlier in sexual maturity and have a smaller size. Some people think that it is easy to bend the gut and intestine in low-salt water to breed beans and crabs. Crabs to the farther inland transport are often more lossy. So this left a place for the survival of inland artificial breeding. Inland nurseries also have some of the coastal advantages that can not be replaced, such as locally grown seedlings adapted to the local water system. author
