Custom-Made Systems
Sea Water Cages
Hand-mounted netting systems made from nylon, polyester, Dyneema, or HDPE, custom-built for salmon, sea bass, and sea bream farms in rough offshore conditions.
Fresh Water Cages
Ideal for inland farms and freshwater species like trout and salmon. Hand-mounted Dyneema or nylon nets ensure controlled rope-to-net ratios and long-term durability.
Anti-Predator Nets
Submerged and surface netting to defend against diving birds, seals, and other predators. Available in various mesh sizes including 45mm, 75mm, 100mm, and 200mm.
Treatment Curtains & Bags
Semi-porous nylon and polyester enclosures used for lice treatments and medicated containment. Available in curtain or full bag formats, custom-made per site.
Heavy Weather Mounting
Ropes hand-mounted to UV-stabilised polysteel (12mm–28mm), spliced with loops or rings for extra control in exposed marine environments.
