Biofloc, A Modern Fishing Technology : With the rapid and dynamic change in the human population, the food industry has also started expanding its boundaries with the help of research and technology. Aquaculture technology is also the part of this expanded efforts of scholars and scientists. The expansion in the field is much essential and considered as a core need of time. This help to reduce the use of natural resources like water and land and also help to preserve nature. Discussing Biofloc fish farming in Pakistan, BFT comes first. Biofloc Technology (BFT) is a technique to improve the water quality in aquaculture through balancing the amount of Carbon (C) and Nitrogen (N) which help in producing proteinaceous feed in the water. This proteinaceous feed becomes an autogenerated best feed for the fish species and helps them to grow faster.

About Biofloc Fish Farming
Biofloc is a Profitable Method of Fish Farming. It has become very popular all around the word as an alternative to open pond fish farming. It is a low cost way in which toxic materials for the fish such as Ammonia, Nitrate, and Nitrite can be converted into feed. The principle of this technique is to recycle nutrients. Biofloc helps in cleaning the culture water of the fish while giving an additional source of feed. It is a sustainable and eco-friendly process.
Rearing of fish at high-density requires some waste management system. Biofloc is a waste treatment system at its core. It was developed to prevent diseases from incoming water to a farm.
Biofloc fish farming is one of the successful and most profitable businesses in Pakistan. With it, Pakistan not only fulfils its personal requirements of the consumption of fish species but also able to fulfil the orders from beyond the borders. The conventual fish farming is quite expensive and unproductive in contrast to the Biofloc fish farming with the help of Biofloc technology (BFT). Now it needs to understand how Biofloc Technology actually works? And is Biofloc fish farming a really successful business in Pakistan?
In this article these questions will mainly be addressed:
- What is Biofloc Technology (BFT)? And how it Works?
- Is Biofloc fish farming a really successful business in?
- What is the feasibility of Biofloc fish farming?
These questions are addressed in detail as follows:
What is Biofloc Technology (BFT)? And how it Works?
Biofloc Technology (BFT) is an environment-friendly technique used for the production of situ microorganisms. These microorganisms are produced as a hygienic food for the fish species. Because of this technique, fish farming requires zero or minimum exchange of water. Because of this technique helps in balancing the level of Nitrogen and Carbon in the water which are really essential for the production of microorganisms and bacteria’s sot that to feed the fish species (as natural feed) and save cost on feeding them with artificially produced feed.
Which fish can be grown in Biofloc?
Best five fish species for biofloc fish farming in India
With growing demand for Inland fish farming, people are opting biofloc as alternative to other traditional types of fish farming.- TILAPIA:
Rich in taste, tolerant to wide variety of water conditions like high salinity, high water temperature, low dissolved oxygen and high ammonia. - CATFISH:
Great taste, highly resistant to disease and parasites,fast growth, easy to farm in warm climates making it the 2nd most preferable choice for freshwater fish farming. - CARP:
High acceptability to consumers due to it's nutritive value and fast growth rate. They are tough, resistant to disease and can adjust according to the water conditions. - BASS:
Quality taste, white meat with high market value and well suited for biofloc aquaculture. They can live, grow and mature in fresh water, can tolerate wide range of salinity from 0 ppt to 35 ppt and above making them natural capable for aquaculture.
What is biofloc best suited for?
Multiple studies have shown that bottom-dwelling species like shrimp and tilapia are best suited to biofloc production. Since the bacterial load in the water is constantly shifting, fish must be relatively resistant to environmental challenges. Sensitive species will not thrive in this environment.
How does Biofloc System Work?
This Profitable Method of Fish Farming is practised in a tank which comes in various sizes. Most common size is of 4 diameter. Biofloc technology converts unused feed and aqua animal feces into food in a culture system while exposed to sunlight creating a protein rich live feed. By converting excess into food again, the cost of feeding comes down.
Heterotrophic bacteria is the main component of Biofloc. It reduces the Ammonia and Nitrite produced by fish feeding. These Heterotrophic bacteria consumes Ammonia converting it into protein. This can be consumed by fish then for growth. It works as actual feed for the fishes. It’s nutritional values are also good.
Is Biofloc fish farming a really successful business in Pakistan?
This is really important to know Biofloc fish farming success factor in Pakistan. Pakistan is one of under developing countries. The country is equipped with comparatively fewer expertise resources. So, individual and the SMEs struggle and work at their own to build the related expertise by exercising consistently and learn this expertise on their own. So, people here in Pakistan are capable enough to gather the necessary information from valid sources, and have already executed and have started working on Biofloc fish farming using Biofloc Technology. 10 different cases have been gone through regarding the people and SMEs who have stated or have shifted from conventional farming to Biofloc fish farming. 10 out of 10 have confirmed that they are quite successful and satisfied with the right and in time decision of stating Biofloc fish farming in Pakistan. This made it 100% success rate which is quite significant to be considered.
How Biofloc helps in cost saving & can double your income?
This Profitable Method of Fish Farming or Biofloc Farming cuts all the major costs so that the savings can be really big. Several factors such as Huge operational costs, cost of vast lands, high costs of feeding, disposal and discharge of waste sludge will not be problems when your opt for this method.
In Aquaculture, the major cost is due to feeding ingredients for fishes. When fishes are fed with high protein diets, approximately 70% of it is discharged as waste in surrounding culture water in the form of nitrogen. With biofloc, we can recycle this waste into feed again reducing the expense of high protein feeds. Biofloc systems also reduces the spread of pathogens while also improving the fish health.
By cutting all these costs, you, yourself can assess that it will easily double your income by increasing quantity of fishes while not compromising on quantity.
What is the feasibility of Biofloc fish farming?
Biofloc fish farming requires few Biofloc Technology tools and a water tank which need to be at least 12 by 12 feet. The total cost for 500 fish species is given as follows:
biofloc fish farming cost
Each tank costs a maximum of Tk 45,000 (USD 531.386). There is aerator, generator and a blower. In total, the cost of construction is around Tk 4.5 lakh (USD 5313.42) and some more for feed and fingerlings for the 12 tanks. Each tank will serve for five years with 20 harvests, four harvests a year. They sold fishes worth Tk 67,100 (from a single tank and one harvest) and earned profit of Tk 22,100.
Investment:
Investment in Biofloc Fish Farming is provided a very good return. One can start with a single biofloc fish tank. The area which is required to set up for a single tank is around 4.5 diameter. The cost for the setup of a single tank is around 45,000 rupees, Which is a one-time cost.
Profit:
In a single-tank we can put around 600 fish and if calculate the cost of feed which will be around 12,000 rupees for four months. If we consider other variables which will be around 8,000 rupees. We can still earn a profit of 20,000 per tank in 4 months.
Benefits of Biofloc System:
The flocs themselves are protein-rich and provide fish and shrimp with a good source of vitamins and phosphorous. The authors explain that allowing the microbial flocs to proliferate can improve water quality and immobilise toxic nitrogen. Farmers have also reported greater productivity indicators with the system when compared to conventional aquaculture techniques.
- Eco-friendly culture system.
- It reduces environmental impact.
- Improves land and water use potency
- Limited or zero water exchange
- Higher productivity (It enhances survival rate, growth performance, feed conversion within the culture systems of fish).
- Higher biosecurity.
- Reduces pollution and also the risk of introduction and unfold of pathogens
- Cost-effective feed production.
- It reduces the employment of protein-rich feed and also the value of ordinary feed.
- It reduces the pressure on capture fisheries that is., the employment of cheaper fish and trash fish for fish feed formulation.
Disadvantages of Biofloc Technology
There’s more to biofloc than meets the eye. The system requires a startup period and yields aren’t always consistent between seasons. Since producers must constantly mix and aerate culture water, energy costs could be higher than expected.
- Increased energy requirement for mixing and aeration
- Reduced response time because water respiration rates are elevated
- Start-up period required
- Alkalinity supplementation required
- Increased pollution potential from nitrate accumulation
- Inconsistent and seasonal performance for sunlight-exposed systems.
Material Require to start Biofloc Fish Farming:
All mention material are avaible on online. Some material like Biofloc Fish Tank is also available on site like Indiamart, Sulekha etc. You can order this material from any vendor.
The Fixed Cost:
- A 13 by 13 feet tank may cost in the range of Rs. 30,000 to 40,000
- A motor connected with 2 solar plates which can induct air in the water tank as an essential part of Biofloc technology BFT will cost Rs. 30,000
- BFT equipment and water quality testing kit will cost Rs 10,000.
The rest is the operational cost and it varies depending on where you stating this project. Like if an individual is starting it in his/her home, this operational cost will be just insignificant in comparison to taking it out of the home. One tank of 13 by 13 feet is enough to make your project commercialized.
