Effects of Salinity on Growth of Tilapia nilotica and Tilapia mossambica.

Tilapia has wide-range tolerance to salinity, and most Tilapia species can survive in both fresh water and seawater. In this study, the survival rates, absolute growth rates and instantaneous growth rates of Tilapia nilotica and Tilapia mossambica in waters with four different salinities (0%., 10%., 20%., 30%.) were investigated. The results showed that the growth of T. mossambica was trended to be increased with the increased salinity, and it is suitable to be farmed in seawater; however, the growth of T. nilotica was trended to be decreased with the increased salinity, and it is suitable to be farmed in fresh water.
