About RAS
Sustainable and Efficient
Fish Farming
The Recirculating Aquaculture System (RAS) is a high-efficiency and environmentally friendly modern aquaculture technology. It continuously recycles and reuses the culture water through a water treatment system, significantly reducing water consumption while enhancing farming efficiency.
The Core Operating
Principle of RAS
Smart Aquaculture
IoT-Integrated RAS
for Automated
Management
Remote Monitoring
- Access real-time water quality data via mobile or computer.
- Optimize management decisions with accurate data.
Intelligent Alerts
- Detects abnormal water quality changes.
- Sends automatic alerts to managers for timely intervention.
- Helps prevent potential losses.
Automated Control
- Adjusts water flow, oxygen levels, and temperature automatically.
- Ensures optimal farming conditions.
- Reduces the need for manual intervention.
Heavy Metal
Contamination
Contaminated seafood can cause
nerve damage, organ diseases,
and child development issues.
Microplastic
Contamination
Plastic waste breaks down
into microplastics, which
enter the human food chain
via seafood.

Safety
01 Traditional Method
Eco-Friendly & Water-Saving
Requires frequent water changes, leading to water wastage and environmental pollution.
Stable Water Quality & Smart Monitoring
Relies on manual monitoring, increasing the risk of sudden water quality deterioration.
Controlled Environment, Year-Round Production
Strongly affected by weather, water availability, and seasonal climate changes.
High Economic Benefits
Frequent fish diseases and low survival rates result in long investment recovery periods.
02 RAS Technology
Eco-Friendly & Water-Saving
Saves over 90% of water, using a closed-loop system that recycles water without pollution.
Stable Water Quality & Smart Monitoring
Automatically detects and regulates pH, dissolved oxygen, and ammonia levels to maintain optimal growth conditions.
Controlled Environment, Year-Round Production
Indoor farming ensures consistent production throughout the year.
High Economic Benefits
Higher survival rates (>90%), faster growth, reduced losses, and improved profitability.
01 Traditional Method
High Labor Costs & Complex Management
Water changes, pond cleaning, fish harvesting, and removing dead fish require significant labor and multiple workers.
Long Farming Cycles, Slow Capital Turnover
Growth is slow due to environmental factors, extending farming cycles and making it difficult to recover investment.
High Failure Rate, Difficult Investment Returns
Strongly affected by weather, disease, and pollution, with low survival rates (30-70%), risking financial losses.
02 RAS Technology
Efficient Tank Management with Minimal Labor
Automated control systems enable a single person to manage multiple tanks, reducing labor costs.
Optimized Water & High-Density Farming: Accelerating Growth for Faster Returns
Optimized water conditions and high-density farming accelerate growth cycles, ensuring faster returns.
Controlled Environment: Ensuring Survival Rate
Controlled environment ensures high survival rates (>90%), significantly improving farming success.
01 Traditional Method
Unstable Water Quality, High Disease Risk
Water bodies are exposed to natural environments, making them susceptible to pollution. Managing water quality is difficult, leading to frequent outbreaks of disease.
Severe Environmental Pollution & Wastewater Discharge
Frequent water changes and wastewater discharge pollute rivers and lakes, potentially violating environmental regulations.
Weather-Dependent, Unstable Production Cycle
Extreme temperatures, heavy rain, drought, or red tides can cause mass fish mortality.
02 RAS Technology
Stable Water Quality, Low Disease Risk
Smart water quality monitoring reduces disease risks, improving survival rates by over 90%.
Environmental protection and no risk of violation
Closed-loop water system eliminates pollution and wastewater discharge, ensuring compliance with environmental standards.
Indoor Controlled Environment for Uninterrupted Production
Indoor controlled environment allows year-round farming, unaffected by weather conditions.
01 Traditional Method
Antibiotic Dependence, Food Safety Concerns
High disease occurrence leads to heavy antibiotic use, posing food safety risks.
02 RAS Technology
Antibiotic-Free Farming
Antibiotic-free farming produces healthier, safer seafood that meets high-end market standards.
