Abstract
The research is conducted on May to June of 2012 at Fishery Laboratory of University 45 Makassar. It is aimed at understanding the effect of salinity change on the survival and growth of Nile Tilapia O. niloticus. Research involves five treatments in which each treatment includes the salinity rates of 11, 17, 23, 29 and 35 ppt. Research is initiated by adapting Nile Tilapia O. niloticus juvenile to salinity 5 ppt for 10 days. The salinity of media water is then increased slowly to 11, 17, 23, 29, and 35 ppt until the day 20. At the day 21 to the day 31, the salinity of media water is decreased until it reaches 5 ppt. Result of research indicates that the highest level of survival and growth of Nile Tilapia O. niloticus is found at salinity 17 ppt, while the lowest is salinity 35 ppt. It seems that Nile Tilapia O. niloticus has the high adaptation rate at salinity 17 ppt (82.23 %) and provides the best growth rate (6.43 %/ day).
