Meaning Of Biofloc

Serves as seeding for biofloc formation. Development of biofloc system It may take a few weeks depends on the biomass.

Transition foam formation then it get brown.

Meaning of biofloc. Biofloc technology is a technique of enhancing water quality through the addition of extra carbon to the aquaculture system through an external carbon source or elevated carbon content of the feed. In short BioFloc means a biological process to culture group of Microorganism called bacteria. In aquaculture ponds Biofloc Technology removes toxic metabolites and through microbial mass protein production.

Biofloc technology was developed in the 1990s as a way for fish and shrimp farmers to conserve feed inputs and utilise wastewater during production. Therefore we should think first how to culture Bacteria in biofloc system and then can think about fish.

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. BioFlocTechnology BFT is an aquaculture system which forms a biota with limited or zero water exchange under high stocking density using strong aeration. Emission of toxic metabolites.

Biofloc is a diverse mixture of suspended particles and a range of extracellular polymer-related microorganisms. The basics of biofloc. Biofloc technology is an eco-friendly technique used for the production of microorganisms.

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. Biofloc system is a budget friendly and cost effective feed production which does not require much amount for feed cost. 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.

Biofloc is a heterogeneous aggregate of suspended particles and variety of microorganisms associated with extracellular polymeric substances. It is composed of microorganisms such as bacteria algae fungi invertebrates and detritus etc. What is biofloc and why bacteria is so important in this system.

Biofloc technology BFT is as an environmentally friendly aquaculture technique based on in situ microorganism production. This promoted nitrogen uptake by bacterial growth decreases the ammonium concentration more rapidly than nitrification Hargreaves 2006. Biofloc Technology BFT one of the innovative waste management and nutrient retention technologies offers a solution to solve the problems.

These microorganisms are converted into hygienic food for the fish. 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 a technique of enhancing water quality focused on a more efficient use of nutrients and lower water consumption.

Managing biofloc systems is not as straightforward as that however. Transition is fast with tilapia longer with shrimp Add carbon if TAN is above 2 mgl Adding clay wheat bran etc. Biofloc plural bioflocs A bioflocculation system.

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. The main concept is that producers could piggyback off the nitrogen cycle and let beneficial bacterial colonies proliferate in culture water. As long as there is sufficient mixing and aeration to maintain an active floc in suspension water quality can be controlled.

Biofloc is composed of microorganisms such as bacteria algae fungi invertebrates and detritus etc. In other words biofloc is a symbiotic process that includes confined aquatic animals heterotrophic bacteria and other. Biofloc is made up of bacteria.

Biofloc systems use a counter-intuitive approach allow or encourage solids and the associated microbial community to accumulate in water. 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.
