| Abstract | This study aimed to investigate the appropriate carbon sources combined with molasses in a biofloc system for tilapia culture. Three carbon sources including rice bran, ground bread crumb and corn meal were selected to induce a biofloc system. This experiment was conducted in the concrete tank size 1 ? 1 ? 1 m3 with high aeration to achieve the dissolvedoxygen at least 4 mg/L. The stocking density was 30 tilapia fingerlings/m3 . Fish were fed with pellet feed followed tilapia feeding program and this experiment was run for six months. The water quality parameters were monitored twice a day. The results showed that there were no significant differences (P > 0.05) in weight gain, survival rate, average daily weightgain and specific growth rate among treatments while using molasses with ground bread crumb gave the highest feed conversion ratio and total suspended solid (P < 0.05). In summary, molasses combined with ground bread crumb was the best carbon source for biofloc production in tilapia culture. |
