How Biofloc Technology is Best Fish Farming Method ?

What is Biofloc Technology ?

It is an innovative and cost-effective technology in which toxic materials to the fish and shellfish such as Nitrate, Nitrite, Ammonia can be converted to useful product, ie., proteinaceous feed.

Protein sources in feed for farmed fish. … Fish meal is an ideal protein source for aquafeed because it has a high protein level (65% to 72%) with an ideal proportion of all ten indispensable amino acids that meet the requirements of all fish species.

It is the technology used in aquaculture system with limited or zero water exchange under high stocking density, strong aeration and biota formed by biofloc.The culture of biofloc will be productive in the case of culture tanks exposed to sun.

Benefits of Biofloc 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 bio-security.

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.

Every year interested practitioners, scientists, and others come together at various aquaculture conferences to present and discuss the most recent findings related to BFT. Look for a Biofloc Session at the next World Aquaculture Society (WAS) or Aquacultural Engineering Society (AES) meeting; anyone with any interest in BFT is encouraged to attend and the sessions are filled with discussions about current BFT issues. A Biofloc Steering Committee made up of members from around the world strives to ensure that the most relevant issues are addressed and the group welcomes feedback and questions from anyone interested in BFT.

Disadvantages of Biofloc Technology

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

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. The dried biofloc is proposed as an ingredient to replace the fishmeal or soybean in the feed. The nutritional quality is good; however, only limited qualities are available.
