THE NETS’ STRENGTH IS RETAINED, EVEN AFTER 20 YEARS AT SEA
escapes in Norway are as a result of fish escaping through holes in nets caused by preda- tors or abrasion – two factors that the EcoNet can resist. Our EcoNets are made from very strong and lightweight PET (polyethylene terephtha- late) – a long life net technol- ogy has been in use for over 20 years and is easily recy- clable. The nets’ full tensile strength is also retained, even after 20 years in the sea, and these properties make them virtually escape and predator proof. Moreover, the non-fibre material has a surface that re- sists fouling and makes it easy to clean using net cleaners. And the semi-rigid structure of the EcoNet keeps the net shape intact and maximises water flow and oxygen.

All these factors contribute to a net system that requires fewer net weights to keep them in place, which means there is less load on the moor- ing systems and more reserve buoyancy for the cages. The reduced deformation and strength means there is less risk of net damage from abra- sion and predators.
Although semi-rigid, it can still be handled in similar ways to nylon. However, as the EcoNets are being tested in different markets, new and better techniques will be developed to simplify net han- dling and to ensure the best possible fish husbandry. As with all our products, our nets are continually improving as a result of close collabora- tion with our customers.
