David Ferron Lozano Veterinary Medicine School UAB June 2017 The BFT is more efficient and sustainable system than the conventional ones in aquaculture when it comes to waste and nitrogen management. Biofloc technology BT is defined as the use of aggregates of bacteria algae or protozoa held together in a matrix along with particulate organic matter for the purpose of improving water quality waste treatment and disease prevention in intensive aquaculture systems. There are strong economic incentives for an aquaculture business to be more efficient with production inputs especially the most costly feed and most limiting water or land.
Transition is fast with tilapia longer with shrimp Add carbon if TAN is above 2 mgl Adding clay wheat bran etc. A Saranya C Kumaran M and Rashmiranjan Das 22-32 5 Integration of submerged substrates in biofloc based system P. Ii nutrition increasing culture feasibility by reducing feed conversion ratio FCR and a decrease of feed.
Communication mechanism regulates the expression of virulence factors Defoirdt et al 2004 17. Such source is produced in a form of biofloc meal mainly in bioreactors. The use of microbes as feed either filtrated directly from the water or recovered to become protein meal is very promising.
Biofloc technology BFT application offers benefits in improving aquaculture production that could contribute to the achievement of sustainable development goals. Biofloc technology was known to improve the shrimp growth performance and water quality in several ways. This technique enhances water quality in aquaculture by balancing carbon and nitrogen in the system by recycling waste nutrients such as nitrogen into.
In relation to the latter the application of biofloc technology in grow out systems of some aquaculture species could improve net productivity by 843 relative to the non-biofloc control traditional with water exchange clear water system or recirculating aquaculture system. Biofloc technology BFT is considered the new blue revolution in aquaculture. Biofloc technology BFT has emerged as new alternative for sustainable aquaculture which could contribute to FAO Sustainable Development Goals SDGs related to food security.
The importance of biofloc technology in aquaculture as an effective bioremediation tool for environmental problems means of poverty alleviation and meeting food security in the coming years is discussed. The introduction of biofloc technology in aquaculture is a boon to the aquatic farmers and especially in the brackish water as shown in Fig. Transition foam formation then it get brown.
The aim of this review is to present and show the biofloc technology BFT as a sustainable aquaculture system. On the 6th page of this PDF file you have the Odisha Biofloc Tech Fish Farming Scheme 2020 application form. Shyne Anand and Sujeet Kumar 33-35 6.

Bioflocs might also contain al 2008 18 has been proposed as a new strategy to control immunostimulatory compounds since biofloc technology deals bacterial infections in aquaculture as this cell-tocell with bacteria and bacterial products.
Development of biofloc system It may take a few weeks depends on the biomass. Odisha Biofloc Tech Fisheries Scheme PDF containing the detailed information of the scheme will open Direct link Promotion-of-Intensive-Aquaculture-through-Introduction-of-Bio-floc-Technology-during-the-year-2020-21. I maintenance of water quality by the uptake of nitrogen compounds generating in situ microbial protein.
Furthermore biofloc systems may. Panigrahi 13-21 4 Biofloc technology. In places where water is scarce or land is expensive more intensive forms of aquaculture must be practiced for cost-effective production.
