फीड (चारा) लागत में कमी: बायोफ्लॉक में मछलियों को सूक्ष्मजीवों द्वारा पोषण मिलता है, जिससे फ़ीड की लागत घटती है।
The usage of Biofloc technology aids to improve h2o and land use rates. It lowers environmental effects. It's really a restricted or zero h2o Trade system.
Four policies must be adopted when feeding fish. Firstly, an everyday feeding agenda must be followed, because infrequent feeding will have a little bit measurable effect on development. The fish should be fed, on each day foundation over the heat months in advance of harvest. The feed amount has to be calculated via the farmer determined by precise sample bodyweight details collected at the end of each and every month.
क्यों तिलापिया बायोफ्लॉक के लिए उपयुक्त है?
To obtain this, producers essential to maintain an increased carbon to nitrogen ratio in their ponds. This would encourage the growth of heterogeneous microbes – microbes that stop working natural carbon within the encompassing environment.
Diminished Environmental Influence: Biofloc fish farming is definitely an eco-friendly technique of fish farming, since it reduces the environmental effect of fish farming. The method lowers the necessity for water exchange, which really helps to preserve h2o and decrease the environmental effect of fish farming.
The flocs are full of protein and supply fish and shrimp with an excellent supply of vitamins and phosphorus. Farmers have also reported bigger productiveness indicators with the system when compared with traditional aquaculture strategies.
Since the microbial community within a Biofloc Neighborhood is continually changing, it's best to choose fish which are incredibly hardy within their surroundings.
