摘要(Abstract)：

盐度30、pH7.5～8.5、温度27～30℃条件下,将刚刚蜕壳的远海梭子蟹放入不同钙浓度梯度(0～400 mg/L)的人工海水中,进行钙浓度对远海梭子蟹蟹壳硬化影响的实验。结果表明:0～12.5 mg/L浓度组的软壳持续时间在10.4～11.4 h之间,25～200 mg/L浓度组的软壳持续时间在6.1～7.7 h,400 mg/L浓度组的软壳持续时间为4.4 h;不同浓度组下,壳宽的增加差异不显著(P﹥0.05),壳长的增加差异也不显著(P﹥0.05);50 mg/L浓度组与400 mg/L浓度组体重增加差异显著(P<0.05),其它各浓度组之间体重增加差异不显著(P﹥0.05)。
