The present study was conducted to investigate the effect of different level of salinities<br />

on survival rate and proximate composition of juvenile Nile Tilapia, Oreochromis<br />

niloticus. A total of 99 individual of tilapia juveniles with an average weight of 14g to<br />

17g were acclimatized in controlled flow-through tank for fourteen days. Tilapia<br />

juveniles were then subjected to three different levels of salinities 0, 5 and 15ppt for<br />

one week exposure. Proximate composition consists of moisture, ash, protein and<br />

lipids were determined using the edible flesh of tilapia. Results indicate that there<br />

was no significance difference detected on survival rate of tilapia (p=0.8185). Survival<br />

rate in the lowest salinity (control tank) shows the highest survival rate (96.97%) as<br />

compared to other treatments in experiment. For the proximate analysis, samples<br />

from control tank contains significantly higher in protein content, 88.12±1.6%<br />
