We have already been introduced to the Biofloc fish farming technology, hence we are going to move ahead and discuss the advantages of this relatively new aquaculture technique.
Advantages of Biofloc technology
- It is an eco-friendly fish culture technique.
- Biofloc technology improves land usage efficiency.
- Biofloc technology required zero or negligible water exchange.
- It greatly reduces the negative impact on the environment.
- Productivity of fishes using biofloc technology is comparatively higher.
- It reduces the cost of standard fish feed.
- Security is higher as compared to traditional fish farming methods.
- During harvest the water can be used as liquid fertiliser.
Brief explanation of the advantages of Biofloc technology:
1. It is an eco-friendly fish culture technique:
Since the biofloc technique is like a closed environment hence there is very less chance of introduction or spread of pathogens into the culture tank. There is also almost zero chances of leakage of harmful compounds that may affect the environment negatively. Hence, it is totally pollution free.
2. Biofloc technology improves land usage efficiency:
Traditionally, fishes were cultivated in large scale ponds and lakes, which required a larger area of land where these water bodies existed, whereas, biofloc fish tanks are comparatively way smaller hence requiring lesser area of land. People of India and Bangladesh have constructed biofloc tanks inside their house premises, which is a testament to the point.
3. Biofloc technology required zero or negligible water exchange:
The main objective behind this Biofloc technology was to minimize or nullify the need for routine water exchange because it is not possible and not very economic. Using this technique, the water is maintained free of toxic compounds so the water is fresh and free from all toxin buildup. Hence, there is almost zero water exchange if you are using biofloc fish farming technology.
4. It greatly reduces the negative impact of the environment:
Biofloc fish farming technology prevents water pollution, and environment pollution due to release of toxic materials into the environment. So, negative impact on the environment is reduced.
