Aquaculture Ras System for Land-Based and RAS Facilities
Aquaculture Ras System for Land-Based and RAS Facilities
Fish Tank: Tanks where fish are raised, allowing for controlled, high-density stocking.
Mechanical Filter:Removes solid waste (fish waste, uneaten feed) to prevent excessive bacterial growth.
Biological Filter (Biofilter): Uses bacteria (like Nitrosomonas and Nitrobacter) to break down toxic ammonia—a byproduct of fish metabolism—into harmless nitrate.
Degassing & Oxygenation: Removes accumulated and adds pure oxygen or air to ensure high dissolved oxygen levels (above 4 ppm).
Disinfection: Uses UV-C light or ozone to kill pathogens, reducing the need for antibiotics.
Main Advantages
High Control: Stable environmental conditions (temperature, light, oxygen) optimize fish growth and health.
Sustainability: Drastically reduces water consumption compared to traditional flow-through systems.
Reduced Disease: Enhanced biosecurity minimizes pathogen exposure and eliminates the need for antibiotics.
Local Production: Allows for farming near high-demand urban areas, lowering transport costs and carbon emissions.
Holly’s fish farming tanks are suitable for a wide range of land-based aquaculture applications:
1.RAS (Recirculating Aquaculture Systems)
Configured for effective water flow and seamless integration with filtration and degassing systems.
2.Smolt Production
Custom diameters and depths designed to promote uniform water conditions and stable growth environments.
3.Grow-Out Tanks
Large-volume configurations with engineered structural capacity for sustained production loads.
Skilled Staff: Requires technically skilled staff to manage the complex, intensive biological and mechanical systems.
Customizable:Every tank solution is tailored to meet the specific technical and operational requirements of your facility — from process flow to footprint optimization.
RAS produces sludge that can be processed into energy (biogas) or used for other purposes, reducing the overall environmental footprint of the facility.
