Fish farming plays a crucial role in Odisha’s economy and food security. To meet the growing demand for fish and improve farmers’ incomes, the Odisha government has introduced a new initiative focused on Biofloc Technology (BFT) for fish production in small tanks. This program supports fish farming in tanks of about 150 to 200 square meters at high stocking densities, backed by subsidy support to encourage adoption. This post explores how this initiative works, its benefits, and practical steps for farmers interested in boosting their fish production.

What is Biofloc Technology (BFT)?

Biofloc Technology is an innovative aquaculture method that improves water quality and fish health by promoting beneficial microbial communities in the water. These microbes convert fish waste and uneaten feed into useful protein-rich particles, which fish can consume. This natural recycling reduces the need for water exchange and feed, making fish farming more sustainable and cost-effective.

In Odisha’s context, BFT is applied in relatively small tanks, around 150 to 200 square meters, allowing farmers to raise fish at high densities without compromising water quality. This method contrasts with traditional pond farming, where water exchange and space requirements limit production capacity.

How Odisha’s BFT Initiative Supports Farmers

The government’s new program offers subsidy support to fish farmers adopting BFT in tanks of the specified size. This financial assistance helps cover initial setup costs such as tank construction, aeration systems, and biofloc starter cultures. By reducing the upfront investment burden, the subsidy encourages more farmers to try this technology.

The initiative also includes training and technical guidance to ensure farmers understand how to manage biofloc systems effectively. Proper management is key to maintaining water quality, controlling stocking densities, and optimizing feed use.

Benefits of Using BFT for Fish Production in Odisha

• Higher Fish Yields

BFT allows fish to be stocked at densities much higher than traditional methods. This means farmers can produce more fish per unit area, increasing overall output.

• Reduced Water Use

Since biofloc systems recycle nutrients and maintain water quality, they require minimal water exchange. This is especially valuable in areas facing water scarcity.

• Lower Feed Costs

Fish consume the microbial protein in biofloc, reducing the amount of commercial feed needed. Feed is often the largest cost in fish farming, so this can improve profitability.

• Improved Fish Health

Beneficial microbes in biofloc help suppress harmful pathogens, reducing disease outbreaks and the need for antibiotics.

• Environmental Sustainability

Reduced water discharge and efficient nutrient recycling make BFT a more environmentally friendly option compared to conventional aquaculture.

Practical Steps for Farmers to Adopt BFT in Odisha

1. Assess Tank Suitability

   Ensure your tank size is around 150 to 200 square meters and can support aeration equipment.

   
   

2. Apply for Subsidy Support

   Contact local fisheries departments or government offices to learn about subsidy application procedures and eligibility criteria.

   
   

3. Set Up Aeration Systems

   Install aerators to maintain oxygen levels, which are critical for biofloc development and fish health.

   
   

4. Introduce Biofloc Starter Cultures

   Use microbial inoculants to kickstart biofloc formation in the tank water.

   
   

5. Stock Fish at Recommended Densities

   Follow guidelines on fish species and stocking densities to avoid overcrowding and stress.

   
   

6. Monitor Water Quality Regularly

   Check parameters like dissolved oxygen, pH, and ammonia to keep the system balanced.

   
   

7. Adjust Feeding Practices

   Feed fish based on their growth and biofloc availability, reducing feed wastage.

   
   

Real-World Example from Odisha

In a pilot project in Cuttack district, a group of farmers adopted BFT in 180 square meter tanks with government subsidy support. They stocked tilapia at densities of 150 fish per tank, nearly double the traditional stocking rate. After four months, the farmers reported a 40% increase in fish yield compared to conventional ponds. Feed costs dropped by 25% due to biofloc consumption, and water use was reduced by half. This success encouraged neighboring farmers to explore BFT as a viable option.

Challenges and How to Overcome Them

While BFT offers many advantages, farmers may face challenges such as:

• Initial Setup Costs

Even with subsidies, some farmers find aeration and tank modifications costly. Group purchasing and cooperative models can reduce expenses.

• Technical Knowledge Gap

Managing biofloc systems requires understanding microbial dynamics and water quality. Government training programs and extension services play a vital role in bridging this gap.

• Power Supply Issues

Aerators need continuous electricity. Solar-powered aerators or backup generators can help maintain system stability.

The Future of Fish Farming in Odisha

The government’s push for BFT in small tanks marks a significant step toward modernizing fish farming in Odisha. By combining technology with financial support, the program aims to increase fish production sustainably while improving farmers’ livelihoods.

Farmers who adopt BFT can expect higher yields, lower costs, and better environmental outcomes. As more farmers gain experience and share success stories, this method could become a standard practice across the state.

Fish farmers interested in this initiative should reach out to local fisheries offices to learn about subsidy deadlines and training sessions. Taking advantage of this opportunity can help build a more productive and sustainable aquaculture future in Odisha.
