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.

Biofloc principle. This natural productivity plays an important role recycling nutrients and maintaining the water quality. The aggregates bioflocs are a rich protein-lipid natural source of food available in situ 24 hours per day due to a complex interaction between organic matter physical substrate and large range of microorganisms. Managing biofloc systems is not as straightforward as that however.

What is Biofloc Fish Farming. BFT is an innovative one from conventional autotrophic to autotrophic- heterotrophic system. Biofloc technology is a technique of improving the quality of water by balancing carbon and nitrogen in the system.

The technology works on the flocculation principal. Shrimp fish biofloc. Biofloc helps in cleaning the culture water of the fish while giving a more source of feed.

It works in the principle of nitrogen cycle in which the ratio of carbon and nitrogen is properly balancedThe size of the Biofloc tank is about 3 to 4 m in diameter and its height is about 1 m. Biofloc principle Biofloc technology BFT is as an environmentally friendly aquaculture technique based on in situ microorganism production. The Biofloc system is not only effective in treating the waste but also grants nutrition to the aquatic.

What is the principle of Biofloc fish farming. It is an eco-friendly process. N ratio through stimulating heterotrophic microbial growth which assimilates the nitrogenous waste that can be exploited by the shrimp cultured spices as a feed.

Panigrahi 13-21 4 Biofloc technology. Introduction to biofloc technology. Microbes like bacteria are generally regarded as a disease causing agent in animal and plants.

Biofloc Fish Farming is a technique of culturing fast growing and medium sized fishes along with probiotics in high density inside a specially designed biofloc tank in which different parameters like oxygen pH TDH are controlled and maintained for the optimum growth and development of fishes. As long as there is sufficient mixing and aeration to maintain an active floc in suspension water quality can be controlled. Standard operating procedure Panigrahi.

But in controlled conditions dense and active aerobic. 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. The principle of this technique is to recycle nutrients found in the Biofloc tank.

Biofloc systems use a counter-intuitive approach allow or encourage solids and the associated microbial community to accumulate in water. Rearing fish at high-density needs some waste management system. Biofloc technology is not only effective in treating the waste but grants nutrition to the aquatic animal.

Then We put probiotics Heterotrophic Bacterias inside the tank at the number of 106 to 109 bacterias per tank of 10000 litres. 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. Now We put fishes inside the tank.

Dauda et al 2018. Shyne Anand and Sujeet Kumar 33-35 6. 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.

Biofloc fish farming works on the principle of balanced CN Ratio. Fish grown in high density minimum of 300 g of biomass per square meter with zero or minimum water exchange. The main component of this system is heterotrophic bacteria which reduces the ammonia and nitrite produced by fish.

The main principle of the Biofloc technique is the generation of nitrogen cycle by maintaining a higher C. Biofloc was introduced as a. A Saranya C Kumaran M and Rashmiranjan Das 22-32 5 Integration of submerged substrates in biofloc based system P.
