The main objective of the present experiment was to test the suitability of biofloc technology in light-limited indoor tanks for rearing Nile tilapia Oreochromis niloticus.
The specific objectives were as follows: (1) to quantify the contribution of biofloc to fish growth and production, (2) to evaluate fish welfare in BFT managed tanks,
(3) to test the effects of crude protein level in supplemental feed on fish growth and productivity in BFT tanks (4) to investigate the effects of protein level/C:N ratio of feed on proximate and taxonomic composition of biofloc and (5) to compare dissolved inorganic nitrogen dynamics. System management aspects have also been discussed.
