Aquamarine® Ultra
Knotted polyester with stainless-steel reinforcementAquamarine® Ultra is a next generation braided knotted construction specifically engineered for aquaculture cage systems operating in harsh and predator prone environments. Designed with a sophisticated multi component reinforced core, Aquamarine Ultra delivers exceptional cut resistance, mesh stiffness, and long term structural stability where conventional netting solutions are unable to perform.
Superior Structural Performance
The braided knotted design ensures compact and uniform mesh formation, resulting in enhanced load distribution and dimensional stability. The reinforced core significantly improves mesh stiffness and overall net rigidity, delivering excellent resistance to deformation under currents, impacts, and operational loads.

Advanced Multi Material Construction
Aquamarine Ultra is manufactured using a high performance HDPE monofilament outer cover, combined with an advanced reinforced core consisting of:
- HDPE monofilament
- Wax infused polyester yarn
- Marine grade stainless steel wire
Key Performance Benefits
- Outstanding cut resistance & predator protection
- High mesh stiffness & structural stability
- Improved wet abrasion resistance
- Minimal sea debris penetration
- Better wall formation
- Sinking nature, reduce lead rope use
- Better axial and lateral stiffness in net
- Applicable for smolt and grow out cages
