What Is Biofloc Fish Farming Technology
Today, closed aquaculture systems are safer for biosecurity, as they need environmental and commercialization advantages over conventional extensive and semi-intensive systems. thanks to the reuse of water reduces the introduction of pathogens and exotic agents within the external environment. Such a sort of environmentally friendly technology for closed aquaculture is Biofloc Technology (BFT). Greater retention and recycling of nutrients has been administered internally without a better cost compared to standard waste management technologies, like aquaculture and biofiltration recirculation systems, both of which require complex, costly, laborious internal filtration and economically impossible. BFT is innovative, from the traditional autotrophic system to the autotrophic-heterotrophic system. Microbes like bacteria are generally considered as causative agents of diseases in animals and plants. But under controlled conditions, dense and active aerobic microbial communities control the qualities of water through the immobilization of toxic metabolites in microbial proteins and recycle garbage and increase food efficiency. Compared to the traditional photoautotrophic system, BFT has more advantages, like variation of dissolved oxygen and proton concentration, which is restricted. The assimilation of inorganic nutrients through bacteria in suspension is a further protein source than algal biosynthesis. Through the decomposition of organic matter by microorganisms results in the assembly of the latest bacterial cells that represent 40-60% of the metabolized organic matter. This aerobic decomposition is often higher during a high C / N ratio (through the source of addition carbohydrates it must be economically feasible) with high oxygen conditions. BFT is an ecological approach in aquaculture that it knows in several names, like the autotrophic-heterotrophic zero exchange system, active sludge or suspended bacterial system, individual cell protein production system, microbial floc system, etc. Now biofloc has been focused internally as an alternate protein for organic, produced mainly within the sort of microbial flour. Many researchers have administered the study of the nutritional acceptability of biofloc.
It is an innovative and cost-effective technology during which toxic materials for fish and shellfish like nitrate, nitrite, ammonia are often converted into useful products, that is, protein foods. it’s the technology utilized in the aquaculture system with limited or zero water exchange under high storage density, strong aeration and biota formed by biofloc. Biofloc cultivation is going to be productive within the case of crop tanks exposed to the sun.
The application of Biofloc technology offers benefits to enhance aquaculture production that would contribute to the achievement of sustainable development goals. This technology could end in higher productivity with less impact on the environment. additionally, biofloc systems are often developed and administered in integration with other food production, thus promoting integrated production systems, with the aim of manufacturing more food and feed from an equivalent area of land with fewer inputs. Biofloc technology remains in its infant stage. far more research is required to optimize the system in reference to operational parameters. in reference to nutrient recycling, MAMP production, and immunological effects
