POND LINER AQUACULTURE
A pond liner is an impermeable geomembrane used for retention of liquids, including the lining of reservoirs, retention basins, hazardous and non-hazardous surface impoundments, garden ponds and Aquaculture Pound to avoid seepage and easy maintenance.
BIOFLOC TECHNOLOGY
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 and biota formed by biofloc.The culture of biofloc will be productive in the case of culture tanks exposed to sun.
-
HIGH INTESIVE FARMING [Prevention of the introduction of diseases to fish farms from incoming water.]
-
Improvement of biosecurity.
-
Improvement of feed conversion.
-
Improvement of water quality.
-
Improvement of water use efficiency.
-
Increasing land use efficiency.
-
Reduction of sensitivity to light fluctuations.
BENEFITS OF BIOFLOC 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).
-
Higher biosecurity.
-
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.
RECIRCULATORY AQUACULTURE SYSTEM (RAS)
Recirculatory Aquaculture System (RAS) is a technology where water is recycled and reused after mechanical and biological filtration and removal of suspended matter and metabolites. This method is used for high- density culture of various species of fish, utilizing minimum land area and water.
Benefits of recirculating aquaculture systems are:
- Fully controlled environment for the fish
- Low water use
- Efficient energy use
- Efficient land use
- Optimal feeding strategy
- Easy grading and harvesting of fish
- Full disease control
- Year-round production
- These are more environmentally compatible systems
- Systems can be expanded
