Abstract: Biofloc technology is recognized as sustainable, eco-friendly and economical technology for fish and shrimp aquaculture due to its numerous beneficial outcomes such as disease prevention, maintaining water quality and promoting growth. One of the most significant species for aquaculture that has drawn interest from all over the world is tilapia because of its unique qualities, which include its capacity to consume particles, its tolerance for moderate oxygen levels, its high density in captivity and its adaptability to a variety of environmental conditions, this species has been successfully cultivated under biofloc conditions. The present study was aimed to evaluate effect of growth performance and survival of Oreochromis niloticus Nile tilapia fish under biofloc system. Sixty day investigation was conducted both with and without biofloc. After a few weeks of all treatments and controls the essential water quality parameters were maintained within an optimal range. The growth parameters were analyzed at end of the experiment after sixty days. Average body weight gain of fish was measured every fourth night. The growth performance of Oreochromis niloticus Nile tilapia fish was found better in biofloc treatment compared to control. Protein efficiency ratio, feed efficiency ratio, specific growth ratio, feed conversion ratio and survival percentage was found better in treatment. Hence it can be concluded that Nile tilapia fish is most suitable for culture under biofloc technological system as compared to conventional farming system.
