effective protection across the entire cage

Aerial view of a circular aquaculture cage fitted with a tensioned bird protection net, covering the full surface to prevent seabirds from entering the pen and interacting with fish or equipment.

Top Nets

Top nets are designed to protect fish stocks by preventing birds from accessing the pen area. They form a physical barrier above the cage, reducing stress on fish and minimizing feed loss.

Developed in close collaboration with aquaculture operators, ELDI top nets are tailored to site conditions, pen geometry and operational routines. The focus is simple: reliable protection and predictable handling.

The nets are manufactured for long service life in exposed environments and can be supplied with supporting poles where required.
