An article: Biofloc Production Systems for Aquaculture (SRAC Publication No. 4503) by John A. Hargreaves (an aquacultural engineer) is available from the Southern Regional Aquaculture Center is available for free downloading from:
Biofloc systems use bacteria on suspended organic material (floc) to both house bacterial to process ammonia efficiently, but also to provide the floc as food to shrimp or fish (Tilapia).
