近年来,三疣梭子蟹苗种生产技术日趋成熟。但育苗用海水的盐度一般在25～32之间,而很少在低于20或高于35的情况下从事苗种生产。据前人对三疣梭子蟹生物生态学的研究,各期幼体在盐度20左右或高于35的一定范围内能够正常发育生长,可未见到有关这方面的育苗技术报道。笔者于近年分别在潍坊市羊口和烟台市海阳从事三疣梭子蟹育 In recent years, Portunus crab seed production technology matures. However, the salinity of seawater for nursery schools is generally between 25 and 32, while the seed production is rarely done below 20 or above 35. According to previous studies on the biological ecology of Portunus trituberculatus, each stage of larvae can grow and develop normally within a certain range of salinity 20 or higher than 35, but there is no report about breeding techniques in this area. In recent years, I, respectively, Weifang City, Yangkou and Yantai Haiyang Porterage crab breeding
