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.
[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.
