Abstract


Oreochromis niloticus is an eurihaline fi sh which has good adaptation level of salinity. Increasing demand of Oreochromis niloticus and availability of salty water in Indonesia give opportunity to develop new strain which is more suitable. The aim of this research is to know the effect of different salinity to Oreochromis niloticus juvenile survival rate and different salinity that can be tolerated. Mean date of all parameters evaluated were sudjected to an analysis of variance (ANOVA). When signifi cant differences were found the means were tested by BNT at  level of signifi cant 1%.The result shows that salinity range 10 to 15 ppt can be tolerated by Oreochromis niloticus with survival rate level of 87,5 % to 81,25 % and 20 to 25 ppt give bad effect toward the survival rate level 25 % to 0 %.
