Shrimp, tilapia and mussel were able to consume and retain N from
biofloc at all particle sizes tested. Caution howevermust be taken in providing
N100 μm flocs for mussel. Overall results show that flocs with
particle size of N100 μmandb48 μmaremore favorable for the aquaculture
species tested in this study as they contain a higher nutritional
value and show higher N recoveries. Therefore particle size seems to
play an important role in the quality of biofloc and consequently affects
the capacity of N retention by each animal. The capability of shrimp, tilapia
and mussel in utilizing biofloc in this study may also be used as a
basic information to develop an integratedmulti-trophic-biofloc system
in whichmanaging suspended solids in BFT systems and enhancing nutrient
utilization efficiency for a more sustainable and environmentally
friendly aquaculture practices will be important
