This study was conducted to determine the effect of different pH level toward Red
Hybrid Tilapia, Oreochromis niloticus fingerlings based on growth performances and
survival rate. This experiment was conducted within 30 days. There are five different
pH used in this study which is pH 2, 4, 7, 9, 11. In each treatment, there were three
replicate conducted and each replicates contained 20 fingerlings. The observation of
fingerlings were done in 5 days once and 5 sample of fingerlings were taken to
measure the Total Length (TL) and Body Weight (BW). Survival measurement was
collect at the day-30 of research. Result showed that fingerlings that were stocked in
pH 7 and pH 9 level showed the highest specific growth rate with average 1.41% and
1.43% meanwhile pH 7 showed the highest survival rate with average 42.22%.
Growth performance was not significantly (P≥0.05) decreased at pH 2, pH4, while the
differences between pH 7, pH 9 and pH 11 was significantly (P≤0.05). No mortality
occurred during the whole experiment. The study showed that the fingerling of
Oreochromis niloticus is suitable and obtain normal growth and for survival rate at
range pH 7-9.
