Who is founder of Biofloc?
Professor Yoram Avnimelech
Israeli Professor Yoram Avnimelech is one of the founders of Biofloc technology. He is the author, among others, of the book entitled “Biofloc Technology – A Practical Guide Book,” which was translated into Vietnamese and made available to the workshops’ participants by the Israeli Embassy in Vietnam.
Which water is best for Biofloc fish farming?
Fill water tank approximately 35-50% by freshwater. Don’t fill more than this because bacteria require a certain environment to grow. Start aeration – Start aeration to mix oxygen with water. Fish require oxygen and during aeration, we flow oxygen through pumps.
How do you maintain floc in Biofloc?
Biofloc systems use a counter-intuitive approach— allow or encourage solids and the associated microbial community to accumulate in water. As long as there is sufficient mixing and aeration to maintain an active floc in suspension, water quality can be controlled.
How much does Biofloc cost?
FULL BIOFLOC SETUP AT YOUR DOOR STEP @ Rs 32072: Free delivery throughout India.
Does Biofloc need sunlight?
Best of all, implementing biofloc principles requires little investment – as only sunlight, a carbohydrate source and plenty of aeration are needed. Biofloc systems bank on photosynthesis to convert uneaten feeds, faeces and excess nutrients into food.
Which is better RAS or Biofloc?
Conclusions. In this study, CW tanks had significantly higher ammonia and pH concentrations, while BF systems had significantly higher nitrite, nitrate, and turbidity levels. The results of this study indicate that clear-water RAS may be a more productive option than biofloc systems for indoor marine shrimp production.
How do you calculate CN ratio in Biofloc?
The CN Ratio Calculation is based on Fish Feed Protein Percentage and the below chart shows the CN Ratio of the feed materials.
- Protein Percentage (%) CN Ratio.
- Let’s calculate Carbohydrates in feed;
- C:N Ratio 10:1 = 120.96 x 10 = 1209.6 gram.
- C:N Ratio 12:1 = 120.96 x 12 = 1451.52 gram.
How do you reduce nitrate in Biofloc?
Carbon source from molasses is effective in reducing concentrations of ammonia, nitrite, and nitrate in red tilapia culture with biofloc technology.

Do we need to change water in Biofloc tank?
In Biofloc technology due to the recycling process of metabolic waste, there is a 30 % saving of feed. In traditional aquaculture, water exchange is required frequently, resulting in wastage of water and larger expenses. Biofloc reduces the need to exchange water.
Is Biofloc fish healthy?
A good nutritional value is found in biofloc. The dry weight protein ranges from 25 – 50 percent, fat ranges 0.5 – 15 percent. It is a good source of vitamins and minerals, particularly phosphorous. It also has an effect similar to probiotics.
How does biofloc work for fish and shrimp?
In BIOFloc Technology, it uses Heterotrophic Bacteria to control the ammonia and convert undigested feed waste into microbial protein cells. In the Ammonia Assimilation process, harmful Ammonia is completely removed from the water and provides a healthy environment for fishes and shrimps.
What are the major problems with biofloc technology?
Biofloc technology is biotechnology Major Problems 1. We need more research 2 . Farmer has to understand the system FARM MANAGEMENT Starting •Goal: Develop the biofloc system. •In lined ponds, you start from almost zero.
What is the typical diameter of a bio floc?
Bio flocs are made of bacteria, protozoa, etc. Typicaly their diameter is 0.1-2 mm. Courtesy of Dr Michelle Burford Mixing and aeration are typical features of bio-technological industry Biofloc technology is biotechnology Major Problems 1.
Who is the father of biofloc fish farming?
Professor Yoram Avnimelech is known as the Father of BioFloc. This new technology has recently gained attention as a sustainable process to control water quality to culture high-density fish farming.
