Biofloc Technology (BFT) and Recirculating Aquaculture
Systems (RAS) are sustainable aquaculture techniques that recycle waste and
maintain water quality. While BFT converts organic waste into fish nutrition,
RAS ensures optimal fish growth through advanced filtration in a controlled
environment.
Biofloc
Technology (BFT) in Aquaculture
Overview:
- BFT is a
sustainable aquaculture technique using a closed tank system to maintain
water quality.
- It employs
beneficial bacteria to recycle organic waste into microbial biomass that
fish can consume.
- Common
bacteria used include heterotrophic species like Bacillus and Pseudomonas.
Advantages
of BFT:
Water Quality Management
- Maintains
clean water by recycling waste.
- Reduces the
need for frequent water changes and external chemical use.
Cost Efficiency
- Converts
waste into fish nutrition, reducing feed costs.
- Economically
viable for aquaculture farmers.
Disease Prevention
- Ensures clean
water and controlled environmental conditions.
- Minimizes
disease risks and reduces reliance on antibiotics.
Suitability for Small-Scale Farms
- Ideal for
backyard operations and small-scale setups.
- Requires low
space and is scalable.
Recirculating
Aquaculture Systems (RAS)
Overview:
- RAS is an
advanced, closed-loop system reusing water through filtration and
purification.
- It combines
mechanical and biological filtration to maintain water quality.
Benefits
of RAS:
Controlled Farming Environment
- Provides
precise control over water temperature, oxygen levels, and cleanliness.
- Promotes
optimal fish growth and health.
Reduced Disease Risk
- Implements
enhanced biosecurity measures.
- Minimizes
pathogen entry, lowering the need for medicinal interventions.
Location Flexibility
- Can be
deployed in urban areas or regions without natural water bodies.
- Aligns fish
farming with market demand and reduces logistical challenges.
