On July 29 and 30, exhibition was held in ashram in honour of DR. Kalbag sir death anniversary. In this exhibition every student have explained their project.
In this exhibition I explained Biofloc projects to students, farmers, teachers. They also asked their questions.
Information which I have discussed with visiters is as follows:
Generally fish farming requires large amount of feed. We have used this method to reduce this amount of feed, by converting waste material into feed. 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.
It is the technology used in aquaculture system with limited or zero water exchange under high stocking density, strong aeration.
Therefore volume of water in tank = 7000 Litre
For 7000L, 7 kg jaggery requires. (1000 L of water requires 1 Kg of Jaggery.)
We can also give azola as feed.
We can use feed matrial which contains carbohydrates.
Added 1 L culture in water tank. Which produces bacteria.
Total numbers of fishes =106, total weight of fishes=9.869 kg
We joined bubbler in system to provide aeration.
Benefits of Biofloc Technology
Redouces extra use of feed.
Eco-friendly culture system.
It reduces environ mental 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).
Cost-effective feed production.
