Abstract: The objective of the present study was to assessment the growth performance and some non-specific immunological effects of growing fish Nile tilapia, Oreochromis niloticus in substrate based biofloc systems. This research was consisted of three types of biofloc systems in which bioflocs were produced by daily supplementation of three different carbon sources, i.e., T1 (only biofloc), T2 (biofloc + bamboo) and T3 (biofloc + nylon mat substrates) using wheat flour as carbon source along with control T4 (without biofloc and substrate) at an estimated C/N ratio of 15 and a control system without any organic carbon addition. Each biofloc system was stocked with 15 fingerlings (4.40 g±0.05) of O. niloticus for growth performance with each group consisted of four replicate aquarium tanks of 70 lit capacity that were reared for a period of 60 days. The present study illustrated the prospects of rearing Nile tilapia, Oreochromis niloticus” in a biofloc-based intensive culture tanks without affecting its survival and growth. It enhanced the fish growth and amplified the non-specific immune response and the antioxidant capability.
