Biofloc Training

 Biofloc technology (BFT) is a relatively new and potentially revolutionary organism that is especially productive for aquaculture. BFT is a sustainable and environmentally-friendly process of aquaculture that controls water quality and harmful pathogens along with providing value-added creation of the microbial protein feed for the aquatic farm structure. What is Biofloc fish farming? High-density rearing of fish generally requires some waste management infrastructure. At its core, Biofloc system is a waste treatment system. Biofloc Training systems were developed to prevent the introduction of disease to a farm from incoming water.

Biofloc systems were developed to increase environmental control over production. In places where water is scarce or land is expensive, more intensive forms of aquaculture should be practiced for cost-effective production. There are strong economic incentives for an aquaculture business to be more capable with production inputs, particularly the most costly (feed) and most limiting (water or land).

What Biofloc systems do?:

Bioflocs provide two critical services that are treating wastes from feeding and providing nutrition from floc consumption. Biofloc systems can work with low water exchange rates (0.5 to 1 percent per day). This long water residence time allows the development of a dense and active Biofloc technology profitability and business sustainability. However, the value of flocs in nutrition is limited at the highest levels of production intensity since the contribution of feed to the growth of cultured animals is overwhelming.

Composition and nutritional value of Biofloc:

Biofloc is a heterogeneous aggregate of suspended particles and selection of microorganisms associated with extracellular polymeric substances. Biofloc is composed of microorganisms such as bacteria, algae, fungi, invertebrates, and detritus, etc. It is a protein-rich live feed created as a result of the conversion of unused feed and excreta into a natural food in a culture system on exposure to sunlight. Each floc is held jointly in a loose matrix of mucus that is secreted by bacteria and bound by filamentous microorganisms or electrostatic attraction. Large flocs are seen with the naked eye, but most of them are microscopic. Floc size range from 50 to 200 microns.

Biofloc system in fishes:

The food and agriculture organization (FAO) recently predicted that the current level of precipitate consumption of aquatic foods is necessary to uphold due to the increasing global population. For this, the world would need an additional 23 million tonnes of seafood by 2020. It can be expected that aquaculture can meet the demand for this additional seafood production, which is estimated to contribute around 93.2 million metric tonnes by 2030. In order to increase aquaculture yields, the country needs additional resources.
