Definition of biofloc. Bioflocculation of microalgae and bacteria addresses this. Biofloc technology BFT is one method with filtration directly from water. This is a major improvement for microalgal technology for wastewater treatment.

This technology basically helps balance the level of Carbon and Nitrogen in the water which are vital for the production of the bacterias and the microorganisms to feed the fish therefore saving the cost on feeding them unnatural food. What is biofloc and why bacteria is so important in this system. The biofloc technology BFT is an intensive and sustainable production system in which microorganisms can contribute to the maintenance of water quality and.

In other words biofloc is a symbiotic process that includes confined aquatic animals heterotrophic bacteria and other. Fish and shrimp are grown in an intensive way minimum of 300 g of biomass per square meter 7 with zero or minimum water exchange. Biofloc technology is a technique of enhancing water quality in aquaculture through balancing carbon and nitrogen in the system.

Transition is fast with tilapia longer with shrimp Add carbon if TAN is above 2 mgl Adding clay wheat bran etc. The biofloc in the shrimp-rearing tank should be considered a dynamic living organism and must be managed as such. This technology may result in higher productivity with.

Comprehensive definitions of Biofloc disseminated in various versions. The major component of biofloc is heterotrophic bacteria. As long as there is sufficient mixing and aeration to maintain an active floc in suspension water quality can be controlled.

It has traditionally been used in outdoor ponds that contain naturally photoautotrophic algae that provides the water. Biofloc technology is a technique of enhancing water quality through the addition of carbon sources to the aquaculture system contained in the feed or external carbon sources. A description of the biofloc and how to feed and support the biofloc follows.

Biofloc technology is an eco-friendly technique used for the production of microorganisms. Definition- The Biofloc is a protein rich macro aggregate of organic material and micro-organisms including diatoms bacteria protozoa algae fecal pellets remains of dead organisms and other invertebrates. Biofloc system reduces the cost of protein rich feed and in turn the cost of standard feed which makes up to 60 of the total production cost.

Biofloc technology BFT is as an environmentally friendly aquaculture technique based on in situ microorganism production. Biofloc system is a budget friendly and cost effective feed production which does not require much amount for feed cost. Currently MaB-flocs are being applied for sewage treatment on lab and pilot scale in Germany New Zealand and Belgium.

Managing biofloc systems is not as straightforward as that however. In aquaculture ponds Biofloc Technology removes toxic metabolites and through microbial mass protein production. This is a major bottleneck of microalgal technology.

Biofloc Technology BFT one of the innovative waste management and nutrient retention technologies offers a solution to solve the problems. Biofloc systems use a counter-intuitive approach allow or encourage solids and the associated microbial community to accumulate in water. 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.

Biofloc Technology is a suspended growth system that depends on active phytoplankton biomass filamentous and floc forming bacteria microbial grazers and aggregates of living and dead particulate organic matter for water quality maintenance. Development of biofloc system It may take a few weeks depends on the biomass. Serves as seeding for biofloc formation.

Transition foam formation then it get brown. Biofloc technology BFT is a technique of enhancing water quality focused on a more efficient use of nutrients and lower water consumption. Basically 2 kind of bacteria is needed in this system.

BioFlocTechnology BFT is an aquaculture system which forms a biota with limited or zero water exchange under high stocking density using. Directly from the water or recovered to become protein meal is very promising. These microorganisms are converted into hygienic food for the fish.

In short BioFloc means a biological process to culture group of Microorganism called bacteria.
