I'm Partha Biswas from Kolkata, India want to start my first start up related to Bioflock Inland fish Firming. Reason behind choosing this start up is firstly this is a green environment project, without wasting water, without pollution air rather air will be enriched with nitrogen dispatch, best waste management, lastly to defeat the unemployment which is the most critical situation in India. This is the only project where I can earn as well as let help to earn to other unemployed youth of my neighborhood through providing them training and encourage them with bio-technical support. Your little help can be greater for my campaign towards me and my unemployed youth.
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.
Bio-floc plays an important role in recycling nutrients and maintaining the water quality. The consumption of bio-floc by shrimp or fish has demonstrated numerous benefits such as improvement of growth rate, decrease of FCR and associated costs in feed. Growth enhancement has been attributed to both bacterial and algae nutritional components, which upto 30% of conventional feeding ration can be lowered due to bio-floc consumption in shrimp.
Also, consumption of macroaggregates can increase nitrogen retention from added feed by 7-13%. In this context, BFT has driven opportunities to use alternative diets.
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).
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.
