Retaining h2o good quality at reduced cost and with out h2o Trade, One more goal of Biofloc systems is additionally to improve expansion charges and feed performance, thus strengthening the profitability and sustainability of farming functions.
Studies have revealed that adopting biofloc technology can increase fish manufacturing by as much as thirty% in comparison with common approaches though cutting down h2o use by approximately 90% and decreasing the necessity for antibiotics and also other chemical substances.
The high-density fish and shrimp culture normally need a waste therapy infrastructure, and biofloc is the greatest waste remedy system. It was disclosed that BFT systems could possibly be proficiently applied to upsurge fish creation by setting up an encouraging marriage between biofloc and fish density, which showed a better potential to recycle nitrogenous waste at superior lifestyle densities (4 million fishes per ha) (Park et al. 2017).
