Red Hybrid Tilapia, the genus Oreochromis, are widely distributed in the wild and
cultivated in fish farms owing to their hardy nature, rapid growth rates and tolerance
of varied environment. Many species are adaptable to a wide range of saline conditions
while others are restricted to fresh- or low-salinity water. The salinity tolerance
experiment was conducted according to the method by Chervinski, J. a. b.(1961)
Chervinski, J. and Yashouv, A. (1971). Out of 5 differences salinity, tested to 15
sample/s of each salinity to get the optimum level of salinity for prefect growth and
survival rates. All the test was showing that the salinity in between 0-2 ppt has shown
was not significance (P≥0.5) in term of growth rate, 12 ppt was significance (P≤0.5)
growth rate, all fish survive at that salinity, with minimal death. Unfortunately, salinity
of 22-32 ppt has shown that low survival of samples. This experiment was conducted
to know the best level of salinity that effect growth and survival rate of samples.
