Three days was the most advisable SRT for treating RAS effluent with SBRs by biofloc technology.

Bioflocs yield could be as high as 2.30–2.54 g VSS/g C.

A type of jellylike bioflocs pellet was designed and directly made from wet bioflocs.

The jellylike bioflocs pellet could be successfully fed to tilapia, and the advisable ADCs of dry matter, protein, crude lipid were 57.28–58.64%, 67.04–69.77% and 76.90–80.80%, respectively.
