Red hybrid tilapia (Oreochromis sp.) is a commercial freshwater fish species which has
high demand worldwide. The present study was carried out to determine the effect of
different water temperatures (28°C, 31°C and 34°C) on survival rate after 48 hours
and growth performance after 16 days. The survival rate of red hybrid tilapia was not
affected in 3 different levels of water temperatures. No significant (p< 0.05)
differences were also observed on the effect of water temperatures in their growth
performance. However, specific growth rate (SGR) and feed conversion ratio (FCR) as
well as total length gain (TLG) and body weight gain (BWG) were better at 28°C of
water temperature compared with 31°C and 34°C. Therefore, this study suggests that
higher water temperature can possibly alter the growth performance of red hybrid
tilapia.
