Biofloc Principle

Dauda et al 2018. Biofloc systems maintain water quality by reducing water pollution and reduce the introduction and spread of pathogens.

Biofloc system is an eco-friendly culture system that reduces the environmental impact on aquatic culture.

Biofloc principle. The Biofloc system is not only effective in treating the waste but also grants nutrition to the aquatic animal. N ratio through stimulating heterotrophic microbial growth which assimilates the nitrogenous waste that can be exploited by the cultured spices as a feed. It is a sustainable and eco-friendly process.

Managing biofloc systems is not as straightforward as that however. The main principle of the Biofloc technique is the generation of nitrogen cycle by maintaining a higher C. Biofloc systems use a counter-intuitive approach allow or encourage solids and the associated microbial community to accumulate in water.

Biofloc technology BFT is an aquaculture tool that requires minimal water exchange promotes the nutrient recycling optimizing resources and produces natural food in situ by forming suspended microbial aggregates in the water bioflocs. Biofloc principle Biofloc technology BFT is as an environmentally friendly aquaculture technique based on in situ microorganism production. Biofloc systems use cheaper food fish and trash fish feed formulation.

The principle of this technique is the generation of nitrogen cycle by maintaining higher C. Transition is fast with tilapia longer with shrimp Add carbon if TAN is above 2 mgl Adding clay wheat bran etc. Rearing of fish at high-density requires some waste management system.

Fish grown in high density minimum of 300 g of biomass per square meter with zero or minimum water exchange. N ratio is maintained through the addition of carbohydrate source molasses and the water quality is improved through the production of high-quality single-cell microbial protein. Biofloc technology is not only effective in treating the waste but grants nutrition to the aquatic animal.

Development of biofloc system It may take a few weeks depends on the biomass. These microorganisms provide multiple benefits such as water quality control pathogen resistance and nutritional supplementation. Serves as seeding for biofloc formation.

The principle of this technique is to recycle nutrients. Limited or zero water exchange. Aquaculture does not take place in isolation although its impact to other human activities is.

This principle acknowledge the opportunity of integrating or linking aquaculture with other producing sector to promote material and energy recycling and optimal use of resources. Biofloc technology has a different. Biofloc technology is a new revolution in aquaculture and is a beneficial approach to sustain our ecosystem.

Biofloc helps in cleaning the culture water of the fish while giving an additional source of feed. The need of Biofloc SystemThis Biofloc system was developed to improve the environmental condition mainly water quality over aquatic animal productionDue to the high stocking density of various fish species and rearing of aquatic animals requires wastewater treatment biofloc system is one kind of wastewater treatment methodIn an aquaculture production system the main. Transition foam formation then it get brown.

Biofloc system is a wastewater treatment which has gained vital importance as an approach in aquaculture. Biofloc or Raceway system maintains a sufficient amount of carbohydratesCarbon present in these carbohydrates promotes heterotrophic bacteria to multiply and synthesize ammonia so maintain the water quality parametersAmmonia produced from the nitrogenous feed as a metabolic product pollutes the water quality. Due to climate change the new technology helps to control the pollution thus give a good business sight.

N ratio through stimulating heterotrophic microbial growth which assimilates the nitrogenous waste that can be exploited by the shrimp cultured spices as a feed. What is the principle of Biofloc fish farming. The basic principle in biofloc systems involves a balance of carbon and nitrogen ratio CN to a level that stimulates the growth of heterotrophic bacteria who in turn utilize ammonia for growth and give off nitrogen gas from the system Dauda et al 2017b.

As long as there is sufficient mixing and aeration to maintain an active floc in suspension water quality can be controlled.
