Aquaculture Benefits

Copper is an essential micro-nutrient, helping achieve good health and development in all forms of life. Due to its natural metallurgical and biological properties, copper alloys are a perfect material for both surface and submersible marine aquaculture enclosures for near- and off-shore sites. Copper-alloy mesh aquaculture cages improve the sanitary conditions, productivity and sustainability of operations for farmers raising salmon, trout, sea bream, sea bass, cod, cobia, yellow tail and other species.

Improves fish health and production

Copper-alloy mesh naturally improves water flow and circulation and helps maintain higher oxygen levels that inhibit parasites and pathogens from growing and infecting fish. This reduces the need for added antibiotics and anti-fouling chemicals. Feeding costs can be reduced by 15%.

Maintains cage volumes

Clean copper-alloy mesh allows pens to maintain their shape against strong ocean waves and currents, even those offshore. Larger, more stable pen volumes prevent fish crowding and help maintain high oxygenation that ultimately improve yields. The mesh also possesses high mechanical strength and formability, which is essential in the creation of effective marine aquaculture containment structures.

Excludes predators and prevents escapes

High-strength copper alloy mesh resists predator attacks, thereby reducing escapes of farmed fish.

Reduces maintenance

Copper-alloy mesh rarely needs to be cleaned, lowering overall costs associated with maintenance and diver risk.


Copper-alloy mesh lasts for six years or more depending on application conditions. Due to its protective patina (coating), it loses little mass over time, and is fully recyclable. Recycled material is used in initial production of copper-alloy mesh, which further reduces CO² emissions, compared with traditional polymer nets. High-strength and corrosion-resistant copper-alloy meshes are compatible with pens commonly used in the marine aquaculture industry, allowing for rapid implementation at existing cultivation centers.
