To provide employment to people during the pandemic period, many State Governments has launched a new scheme for promoting intensive aquaculture through biofloc technology in fisheries.

The scheme will provide livelihood support to entrepreneurs, unemployed youths and interested progressive fish farmers and will also increase fish production in that States. The scheme is most suitable for youths who face unemployment during the pandemic.

The biofloc-based farming system is a new technology for the promotion of intensive fish/ shrimp production in a limited area. A person having small landholding (as small as 150-200 square metres of land) and having either municipal piped water supply or bore well water supply can establish this business with a small investment. The program aims to support fish farmers and young entrepreneurs for livelihood support.

The system is suitable for growing freshwater fish species such as Cat fish like Tilapia, Magur, Pangasius, Anabas and Common Carp depending on local market demands.

Fish grows to about 200 grams within 3 months and 700 -800 grams within 6 months. Therefore, depending on the local market demand, fish can be partially harvested on a daily basis to generate daily income for farmers. Biofloc farming system is also suitable for urban and semi-urban areas. It can be set up even on terraces of buildings and backyard. It offers live or fresh fish to surrounding customers thus fetching higher market prices for the producer. The unit cost for installation of a biofloc unit of two tanks is Rs 1.50 lakh, while a biofloc unit of 6 tanks costs approximately Rs 4 lakh.

Some State Governments provides a subsidy of 40% while a 60% subsidy is provided to SC and ST beneficiaries. This new and emerging technology would boost fish production and encourage small landholders and entrepreneurs to take up fish farming, The Government would provide all technical knowhow for the project.

In Aquaculture, the costliest factors are investment needed for huge spaces to grow targeted species, high-quality feeding and filtrations systems. Availability of land and water are other issues. Water availability is scarce in some regions and lands are expensive. These huge production costs have forced farmers to look for ways. By adopting this Profitable Method of Fish Farming more seafood can be produced by using fewer resources.

What is 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.

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.

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.

BIO-FLOC FISH FARMING

2. Introduction/Background

The global population is expected to grow by another 2 billion to reach 9.6 billion people by 2050, and the demand for animal protein is increasing and it is a challenge of feeding our planet by safeguarding its natural resources for future generations. In this context, aquaculture plays a key role in promoting health by providing animal protein as well as generating jobs and economic opportunities. According to FAO, the world food fish aquaculture production expanded at an average annual rate of 6.2% in the period 2000-2012 from 32.4 MMT to 66.6 MMT.

BFT is considered the new “blue revolution” since nutrients can be continuously recycled and reused in the culture medium, benefited by the minimum or zero-water exchange. Bio-floc technology (BFT) is as an environmentally friendly aquaculture technique based on in situ microorganism production. Bio-floc is the suspended growth in ponds which consist of aggregates of living and dead particulate organic matter, phytoplankton, bacteria and grazers of the bacteria. It is the utilization of microbial processes within the tank/pond itself to provide food resources for culture organism while at the same time acts as a water treatment tank. Thus, this system is also called as active suspension ponds or heterotrophic ponds or even green soup ponds.

IMPORTANCE OF BIO–FLOC SYSTEM

Bio-floc system is a wastewater treatment which has gained vital importance as an approach in aquaculture.The higher C: N is maintained through the addition of carbohydrate source (molasses) and the water quality is improved through the production of high quality single cell microbial protein. In such condition, dense microorganisms develop and function both as bioreactor controlling water quality and protein food source. Immobilization of toxic nitrogen species occurs more rapidly in bio-flocs because the growth rate and microbial production per unit substrate of heterotrophs are ten-times greater than that of the autotrophic nitrifying bacteria. This technology is based on the principle of flocculation within the system.

COMPOSITION AND NUTRITIONAL VALUE OF BIO–FLOC

Bio-floc is a heterogeneous aggregate of suspended particles and variety of microorganisms associated with extracellular polymeric substances. It is composed of microorganisms such as bacteria, algae, fungi, invertebrates and detritus, etc. It is a protein-rich live feed formed as a result of conversion of unused feed and excreta into a natural food in a culture system on exposure to sunlight. Each floc is held together in a loose matrix of mucus that is secreted by bacteria and bound by filamentous microorganisms or electrostatic attraction. Large flocs can be seen with the naked eye, but most of them are microscopic. Floc size range from 50 — 200 microns.

A good nutritional value is found in bio-floc. 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. The dried bio-floc is proposed as an ingredient to replace the fishmeal or soybean in the feed.

3. BENEFITS OF BIO–FLOC CULTURE SYSTEM

• Eco-friendly culture system.
• It reduces environmental impact.
• Improves land and water use efficiency
• Limited or zero water exchange
• Higher productivity (It enhances survival rate, growth performance, feed conversion in the culture systems of fish).
• Higher biosecurity.
• Reduces water pollution and the risk of introduction and spread of pathogens
• Cost-effective feed production.
• It reduces utilization of protein rich feed and cost of standard feed.
• It reduces the pressure on capture fisheries ie., use of cheaper food fish and trash fish for fish feed formulation.

Major cultivable fish species in BFT

A basic factor in designing a bio-floc system is the species to be cultured. Bio-floc systems work best with species that are able to derive some nutritional benefit from the direct consumption of floc. Bio-floc systems are also most suitable for species that can tolerate high solids concentration in water and are generally tolerant of poor water quality. Some of the species that are suitable for BFT are:

• Air breathing fishes like singhi, magur, padba, anabas, pangasius
• Non air-breathing fishes like common carp, rohu, tilapia, milkfish
• Shellfishes like vannamei and tiger shrimp
