System Biofloc
In Indiana uses the biofloc water treatment system for dealing with the metabolic wastes associated with production. Biofloc fish farming material was designed to stop incoming water disease from entering a farm.

The bioflocs serve as a biofilter in the water column and allow feeding rates much higher than in pond culture.
System biofloc. Biofloc systems use a counter-intuitive approach allow or encourage solids and the associated microbial community to accumulate in water. Introduction to biofloc system Biofloc technology is a new revolution in aquaculture and is a beneficial approach to sustain our ecosystem. The function of the Biofloc system is to reduce the nitrogenous metabolic waste ammonia nitrite produced by shrimp feeding and production.
Biofloc is a waste treatment system at its core. Biofloc systems remove metabolic wastes from aquatic production systems. BFT is an environment friendly aquaculture technique based on in-situ microorganism production.
The training and teaching trade of the biofloc system is the most widespread issue now and it has turned into pretty much commercial. Due 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 method. Managing biofloc systems is not as straightforward as that however.
In the Biofloc system you can observe the improved breeding performance. Transition is fast with tilapia longer with shrimp Add carbon if TAN is above 2 mgl Adding clay wheat bran etc. The majority of the discussion to follow deals with this kind of system.
It is assumed that a 35 percent crude protein or 56 percent nitrogen feed is applied at 400 kgday in a 10000-cubic-meter shrimp Biofloc system with an FCR of 13. Bacteria that convert ammonia to nitrate are cultured in the main rearing tank as opposed to in a separate vessel. Primarily Biofloc is a system that treats waste.
Biofloc systems were developed to improve environmental control over production. Serves as seeding for biofloc formation. Author Robert Rode Purdue University Aquaculture Research Lab Manager Department of Forestry and Natural Resources Purdue University Water Quality.
According to Rakocy 2019 personal communication a typical biofloc system contains a clarifier to remove excess biofloc alkalinity supplementation tank to reduce the water acidity heavy aeration a method for inducing a circular current and denitrification tanks Figure 613. The hemato-immunological parameters showed that fish kept in a biofloc system had adequate values comparable to those reported for Mugil. Transition foam formation then it get brown.
Due to climate change the new technology helps to control the pollution thus give a good business sight. They replace biofilters in a classic clear water Recirculating Aquaculture System RAS. The need of Biofloc System.
In places where water is scarce or land is expensive more intensive forms of. Biofloc Technology BFT is considered as new blue revolution since nutrients can be continuously recycled and reused in the culture medium benefited by the minimum or zero-water exchange. It was developed to prevent diseases from incoming water to a farm.
Biofloc is a heterogeneous system of aggregate suspended particles along with a variety of microorganisms such as bacteria fungi algae invertebrates and detritus etc. This Biofloc system was developed to improve the environmental condition mainly water quality over aquatic animal production. Rearing of fish at high-density requires some waste management system.
One more issue needs to be clear fish farming with biofloc. As long as there is sufficient mixing and aeration to maintain an active floc in suspension water quality can be controlled. Biofloc production system water from a full season of catfish growout that was used to maintain market-size fish over the winter was used successfully in the present study for a second year of catfish food-fish production.
Nutritional value in Biofloc system. Development of biofloc system It may take a few weeks depends on the biomass. In order to do cost-effective production the use of more intensive types of aquaculture is always beneficial.
