Frequently Asked Questions

What is a Recirculating Aquaculture System (RAS)?

A Recirculating Aquaculture System (RAS) is a highly controlled fish farming method that filters and recycles water within a closed system. Typically, 90-99% of the water is reused after mechanical and biological filtration, allowing for high-density fish production with minimal water usage and environmental impact.

How does your RAS system save water?

Our RAS systems use advanced mechanical filtration, biofiltration, and oxygenation to clean and recycle water continuously. This allows farms to operate with 90% less water than traditional flow-through systems, making aquaculture viable in water-scarce regions.

Can I get OEM/ODM services?

Yes, we offer comprehensive OEM and ODM services. Our professional design team can customize tanks, systems, and components to meet your specific requirements, branding, and operational needs.

What kind of support do you provide after installation?

We provide lifelong technical support, including remote troubleshooting, maintenance guidance, and on-site service when needed. We also offer training programs for your staff on system operation, water quality management, and fish health monitoring.

Are your systems suitable for different fish species?

Yes, our systems are adaptable for a wide range of species including salmon, trout, tilapia, barramundi, shrimp, and sturgeon. Our experts will help you configure the optimal system parameters for your target species.
