What is Biofloc?

You need to first understand what is BIOFloc, it is a macro aggregate that contains protein-rich organic material that is used as a source of food for the fishes and it also removes harmful ammonia gases from the system to provide optimum water conditions for aquatic animals.

BIOFloc Technology is an advanced fish and shrimp farming technique researched by Professor Yoram Avnimelech (Isreal Scientist) to provide optimum water conditions for the aquatic animals by maintaining the required Carbon Nitrogen Ratio (CN Ratio). 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.

What Biofloc does?

BIOFloc Technology has many advantages over the traditional way of doing fish or shrimp farming. It provides a controlled environment for fish and shrimp farming. Here are few benefits of adapting BIOFloc Technology;

High-Density Fish Farming
Low FCR (Feed Conversation Ratio)
Controllers Ammonia
Zero or Minimal Water Exchange

These are the main reasons to adopt BIOFloc Technology. The main point that grabs the attention of the people, is the High-Density Fish Farming is now possible using the new technology. Yes, you heard me right, within a 15 x 15 square feet area you can culture 2000-3000 fishes, which is quite impossible in small ponds.

It’s lower down the Feed Cost as it develops FLOC, which is a protein and fishes take it as a food. Also, it converts undigested feeds into FLOC, which is consumed by the fishes or shrimps. Feed wastage is completed managed by this technology. That’s the reason BIOFloc helps to cut down the feed cost by at least 25-30%.

High-Protein Feed and Feed Excreta produce harmful ammonia gas inside the water and excess generation of ammonia gases can kill the fishes. 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.

The beauty of this BIOFloc Technology is ZERO Water Exchange. With proper Carbon Nitrogen Ratio (CN Ratio), no water exchange is required. It does not only save water but also saves money.

These are the main reasons why BIOFloc Technology is getting more and more popular among fish and shrimp farmers around the world.

How does Biofloc work?

As I said earlier, BIOFloc is a macro aggregate that controls the system. BIOFloc system is controlled by the colony of bacterias that helps to remove harmful ammonia from the system. Mostly in Biofloc System Heterotrophic Bacteria i.e. Bacillus Group of Bacteria used but there is also another process called Nitrification Process is a biological process of breaking down Ammonia into Nitrate. Let’s discuss how the Nitrification Process work;

When we give Nitrogenous sources into the pond, in the form of Feed or Fish Excreta, it decomposes and produces organic sludges on the bottom of the pond. These organic sludges produce toxic ammonia gases, which is harmful to the fishes.

In the Nitrification Process, Ammonia gets oxidized and converted into Nitrite (NO2–). The Nitrite further gets oxidized and converted into Nitrate (NO3). Among Nitrite (NO2-) and Nitrate (NO3), the NO2- is more toxic and harmful as it enters into the fish or shrimp immune system and blood circulatory system, the fish, and shrimp get killed.

The bacteria which converts Total Ammonia Nitrogen into Nitrite (NO2–) is called Ammonia Oxidizing Bacteria (AOB). These AOB are also known as Nitrosomonas Bacterias.

The bacteria which converts Total Nitrite (NO2–) into Nitrate (NO3) is called Nitrite Oxidizing Bacteria (NOB). These NOB are also known as Nitrobacter Bacterias.

In Biofloc System, mostly people use Heterotrophic Bacteria i.e. Bacillus Group Of Bacteria. These bacteria with Ammonia Assimilation Process remove Ammonia from Biofloc water and also convert undigested feed into micro-bacterial proteins. These micro-bacterial proteins are known as FLOCS and it’s again consumed by fishes. These bacteria help to lower down FCR.

But Nitrifying Bateria only removes ammonia from water but doesn’t convert undigested feed into micro-bacteria protein as Heterotrophic Bateria do.

In the BIOFloc System, we need to grow and feed bacteria to control the system and provide optimum conditions to grow fish. The feeding of bacterias is also known as CN Ratio, how much carbon feed is required to kill nitrogen from the water.

How to Start a Biofloc Fish Farming and Vannamei Shrimp Farming

If you have a good understanding of BIOFloc Technology but still you need to acquire some knowledge understanding the required BIOFloc Tools and Ingredients. Indoor Shrimp Farming and Fish Farming can be also done using this technology.

So far you understood that we need to introduce some helpful bacteria into the system to provide the optimum water condition for fish farming. These bacterias come in packaged powder form, called “Probiotics“. Nowadays it’s easily available in popular online stores like Amazon.

Probiotics contain all the helpful bacteria (Bacillus Group Of Bacteria) which we have discussed earlier. These bacterias are not active when they are in powder form. We need to activate them to perform their task. The details about the bacteria activation process will be discussed latter part of the article.

What else you need to start your own BIOFloc Fish Farming? Here is the complete list;

Probiotics (already discussed)
Carbohydrates (Molasses or Sugar or Jaggery): Helps to maintain the ecosystem i.e. Carbon Nitrogen Ratio
Calcium Carbonate (CaCO3) or dolomite (CaMg(CO₃)₂): Balances the pH in the water
Fish Tank: Most of the people use Tarpaulin Tank for BIOFloc Fish Farming
Aeration Pump and Accessories: Aeration Pump, Air Stones, Air Tubes, and Air Controllers required to maintain oxygen level in the water.
pH Meter: Helps to monitor the water pH level.
Dissolved Oxygen Meter (DO Meter): Monitors the dissolved oxygen level in the water
Salinity Meter: Measures the Salt level in the water
Ammonia Test Kit: Provides presence of Ammonia, Nitrite, and Nitrate in the water
Chlorine Test Kit: Provides presence of Chlorine in the water
Iron Test Kit: Provides presence of Iron in the water
Potassium Permanganate(KMNO4): Used for removing Iron from water, Tank Sanitization and Kill Harmful Bucerias
Water Hardness Check Kit (Check Hardness of Water)
IRON Test Kit (Check presence of IRON Water)
Alkalinity Test Kit (Check Alkalinity of Water)
Raw Sea Salt (No Iodine): Required to maintain the salinity of the water
Imhoff Cone: Measures the Floc level of the water
Water Temperature Meter: Monitors water temperature
Power Backup (Inverter, Generator, Solar Power Backup): Continuous power backup required

Once you have these pieces of equipment in place, the next step is water preparation.

Biofloc Water Preparation Process

Before you introduce fishes into the BIOFloc tank, be ensured that the following criteria are fulfilled;

The Fish Tank & Air Stones are well sanitized with KMNO4 Solution
Ensure Water shouldn’t contain IRON, Heavy Metals, and Chlorin because its harmful for fishes
Use CaCO3 or Dolomite to maintain an optimum pH level of the water i.e. pH7 to pH8
Ensure Water has all the required Minerals in it
Ensure Air Pump provides required Dissolved Oxygen (DO) in the water i.e. DO 4+ is good

Once you qualify the above conditions, the next step is to introduce fishes into the BIOFloc Tank after sanitizing the fishes in the KMNO4 Solution. Don’t feed fishes for the next 12-24 hours because the fish feed will produce ammonia and till now our system is not ready to control the ammonia.

Step1: After Fish Tank and Air Stones are well sanitized in the KMNO4 Solution, pour water into the Fish Tank

Step2: Check the pH level of the water, if the pH is below 7, it needs to be fixed.

Step3: Add Calcium Carbonate (CaCO3) or Dolomite i.e 0.05 gram per liter, initially add a small amount and check the pH level after 4-5 hours. Add more if it’s required. Don’t add more CaCO3 into the water otherwise, it will raise the pH level.

Step4: Add Raw Sea Salt 1 gram per liter, in 10,000 water tank 10kg Raw Sea Salt is required to maintain salinity 1 for Fishes and Shrimps it as per the requirement

Step5: Mix Molasses (0.1gram per liter) with Probiotics (0.03gram per liter) and put it into the Fish Tank

Step6: Ensure the Aeration system should be working all the time.

Step7: Depending upon Probiotics it may take 1-3 weeks to fully activate the bacterias to control the system.

In the BIOFloc system, its recommended not to feed high protein feeds to the fishes. It will imbalance the system, 20% protein feed is proven to be working well in BIOFloc System.

BIOFloc Operational topics will be discussed in other articles on the same website.
