How To Control Floc In Biofloc

If floc increases then the water will become dense and it will be difficult for the fishes to breathe. It is hard to maintain temperature in biofloc operations although temperature is crucial for governing the deflocculation of the flocculants at cold temperatures 4 o C cool conditions 15-18 o.

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

How to control floc in biofloc. In this video you will learn detail inform about pH and its effect on fishes in BioFloc aquaculture. High stocking rates and aquatic animal rearing need wastewater treatment. The volume of formed Biofloc was controlling between 4 to 8mLL by the daily addition of molasses to obtain maximal growth of Biofloc while maintaining water quality and shrimp productivity.

Good control of solids can be achieved by turning over the rearing tank water every 34 days. The bioflocs serve as a biofilter in the water column and allow feeding rates much higher than in pond culture. In aquaculture the strong influential factors are the feed cost accounting to 60 of the total production cost and most limiting factor is the waterland availability.

Development of biofloc system It may take a few weeks depends on the biomass. De Schryver Verstraete 2009. Biofloc system was developed to improve the environmental control over the aquatic animal production.

The main factors are feed cost where it costs around the 60 of the total cost of production and the other limiting factors are land availability permissions and adequate water supply along with waste water treatment. Managing biofloc systems is not as straightforward as that however. Biofloc is the floc consisting of.

If floc increases then replace old water with new. What is the optimal range and how to measure it in BioF. Transition is fast with tilapia longer with shrimp Add carbon if TAN is above 2 mgl Adding clay wheat bran etc.

Then add Caco3 Calcium Carbonate in water. Biofloc is one of the alternative methods to control and improve the water quality in aquaculture this method is commonly combined with domestic waste processing Avnimelech 2009. Salt helps water to maintain TDS and help fish in strain.

If floc decreases then add 25 mg probiotic along with some molasses to your tank. Biofloc systems were also developed to prevent the introduction of disease to a farm from incoming water. First you want to add 1 kg salt per 10000 L of water.

Add Salt Caco3 and Probiotic Now it is an important part of water preparation in the Biofloc system. In the past standard operation of shrimp ponds included water exchange typically 10 percent per day as a method to control Figure 1. If floc decreases then the ammonia level will increase in your tank.

The biofloc fish farming materials system was developed to improve environmental control over the development of aquatic animals. The most influential factors in aquaculture are feed costs and the most limiting factor is waterland supply. Clarifiers are sized to contain 15 of system volume and are operated with a flow rate that gives 2030 minutes of residency time Hargreaves.

Biofloc system is mainly designed to control the aquatic environment especially during the commercial production. As long as there is sufficient mixing and aeration to maintain an active floc in suspension water quality can be controlled. At its core biofloc is a waste treatment system.

Transition foam formation then it get brown. Similarly to Biofloc sampling measurements of water quality parameters including temperature pH level salinity ppt dissolved oxygen DO nitrite orthophosphate and ammonium were measured during. How to make Biofloc ProbioticsAnd how to use Floc makingPlease Subscribe My Channel Update More Biofloc Releted Video.

Serves as seeding for biofloc formation. So maintaining the floc is very important. 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.
