| Abstract: | 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. |
