| 摘 要： | 根据氯化物型盐碱地水质的特点，采用天然海水配置不同盐度的咸水，研究盐度对克氏螯虾幼虾的急性毒性作用，通过试验，克氏螯虾幼虾24、48、72、96h盐度半致死浓度（Lc50）分别为30．37、26．76、25．19和23．93，安全浓度为6．23。试验结果表明，克氏螯虾幼虾对盐度具有较高的耐受性。

| Abstract: | Experiments were conducted to examine the effects of salinity fluctuation on the adaptability of juvenile Procambarus clarkii. According to the water quality in chloride-laden salt marshes, salinity has been regulated and formulated with sea water. Under these conditions research has been carried out to gauge the effect of acute toxicity found in different salinity levels on crayfish. When the levels of salinity are at 24 h, 48 h, 72 h, and 96h, the semi-mortality rates （LC50） are 30.37, 26.76, 25.19, and 23.93, the salinity that does not endanger crayfish is 6.23. |
