HDPE Circular Fish Farming Cages, can also called as round net cage, cylinder net cage, gravity circular cage etc. It has the following characters:
Enhanced stability and durability: Circular cages offer better resistance to wind and waves, ensuring the safety and longevity of the structure.
Efficient space utilization: The circular shape allows for more efficient use of space, maximizing the area available for fish farming.
Improved water circulation: The uniform design of circular cages promotes better water circulation, which is essential for maintaining optimal water quality and promoting fish health.
Reduced stress on fish: The absence of corners in circular cages minimizes stress on fish, leading to improved growth rates and overall well-being.
Easy maintenance and cleaning: The symmetrical design of circular cages makes it simpler to access all areas for maintenance and cleaning tasks.
Versatile and adaptable: Circular cages can be easily modified or scaled up to accommodate different species and varying stocking densities.
Enhanced predator protection: The lack of corners in circular cages makes it more difficult for predators to target fish, providing an additional layer of protection.
Lower construction costs: In some cases, the simplicity of the design and materials used in circular cages can result in lower construction costs compared to other cage types.
Improved monitoring and management: The uniform layout of circular cages facilitates easier monitoring and management of fish populations, as well as the implementation of various aquaculture techniques.
Aesthetic appeal: Circular cages often have a more visually appealing appearance, making them suitable for various environments, including coastal areas and urban settings.
Installation Guide for Deep-Sea Aquaculture Cages**
1. Site Selection
Choose a location with stable water depth (typically 15-50 meters), moderate currents (0.5-1 m/s), and minimal exposure to extreme weather. Ensure compliance with local environmental and regulatory guidelines.
2. Pre-Assembly
- Lay out HDPE floating pipes, connectors, and buoyancy modules onshore or on a dock.
- Assemble the cage frame by connecting HDPE pipes using clamps or thermal fusion welding. Ensure joints are watertight and structurally secure.
- Attach netting to the frame using UV-resistant ropes or carabiners, leaving openings for feed systems and access points.
3. Deployment
- Tow the pre-assembled cage to the installation site using boats.
- Gradually submerge the cage into the water, allowing it to float naturally. Adjust buoyancy modules to achieve optimal stability.
4. Mooring System Setup
- Anchor the cage to the seabed using heavy-duty chains, synthetic ropes, or gravity anchors.
- Connect mooring lines to the cage's corners at a 30°-45° angle to distribute tension evenly.
- Install sinker weights or mid-water buoys to stabilize the cage against currents.
5. Equipment Integration
- Secure feed dispensers, sensors, and anti-predator nets to the cage structure.
- Test all systems (e.g., automatic feeders, oxygen monitors) to ensure functionality.
6. Final Inspection
- Verify the cage's alignment, buoyancy, and mooring tension.
- Check for leaks, loose connections, or netting gaps.
- Monitor the cage for 24-48 hours to confirm stability under tidal changes.
Safety Notes:
- Use weather forecasts to avoid installation during storms.
- Ensure all personnel wear life jackets and follow maritime safety protocols.
Note: This guide assumes standard HDPE cage systems; adjust steps for specialized designs.

HDPE, lightweight high-strength alloy materials and other new materials are adopted in the structure. Computer control, various anti-corrosive, anti fouling (attachments) and anti-aging technologies greatly improve the overall structural strength and flexibility of deep-sea aquaculture net cage, double the service life of the cage, highly reduce the daily maintenance and the cost of aquaculture in unit volume, and improve economic benefits.
