摘  要：
[目的]研究盐度、pH和温度对金钱鱼幼鱼存活的影响,为金钱鱼的养殖提供科学依据。[方法]采取突变试验研究了盐度、pH和温度对金钱鱼幼鱼存活的影响。[结果]金钱鱼幼鱼耐受盐度范围为0~50‰,最高起始致死盐度为54‰。耐受pH范围为5.0~9.7,最高和最低起始致死pH分别为9.9和4.4。耐受温度范围为16~39℃,最高和最低起始致死温度范围为40和15℃。[结论]金钱鱼幼鱼耐酸能力和耐低盐能力较高,对低温的耐受力较弱,适合在中国南方养殖。

摘  要：
[Objective]Tolerance of Juvenile Scatophagus argus to the changes of salinity,pH and temperature was studied,in order to provide scientific reference for the culture of S. argus. [Method]Influences of changes in salinity,pH and temperature on the survival and ingestion of juvenile S. argus were investigated by performing experiments of abrupt and gradient salinity changing. [Result]The results showed that the tolerance salinity range was about 0- 50‰. The upper incipient lethal salinity was 54‰. The tolerance pH range was about 5. 0- 9. 7. The upper and the lowest incipient lethal pH was 9. 9 and 4. 4,respectively. The tolerance temperature range was about 16- 39 ℃. The upper and the lowest incipient lethal temperature was 40 ℃ and 15 ℃,respectively. [Conclusion]The results showed that the juvenile S. argus with a small scale in temperate zones are able to tolerant acid condition and low salinity,which are suitable for cultivation in the south of China.
