Survival and growth performance of red hybrid tilapia fingerlings were evaluated in<br />

different salinities (i.e. 0‰, 7‰, 14‰, 21‰). In the first experiment designed to<br />

demonstrate the effects of instantaneous changes in salinity, tilapia fingerlings were<br />

able to resist abrupt changes from fresh water up to 14‰ salinity without mortality,<br />

while 57.14% mortality incurred at 21‰, when the fish were exposed for 48hs. In<br />

the second experiment of growth performance trial conducted for 15 days, no<br />

significant differences were observed for all the parameters although the highest TLG<br />

was observed at 7‰. This study demonstrates that tilapia can live within a broad<br />

range of salinity particularly in the range of 0‰ to 14‰ without compromising their<br />

survival and growth performance.<br />
