EcoNet - High performance, durability and escape prevention

The non-fibre Polarcirkel EcoNet has a very hard surface that resists marine fouling and makes it easy to clean in the water. Due to the very low water drag resistance, the EcoNet also ensures maximum water flow to the fish. This has resulted in some of the best ever production results in large scale salmon farming, such as higher SGR, lower FCR, lower mortality and higher fish harvest quality.

The EcoNet is certified under NS 9415:2009 to stay in the water for up to 14 years. This eliminates costly net changes and reduce the risk of net handling. Polarcirkel EcoNet has also proven very resistant to predator attacks. Should damage to the net occur, the semi-rigid structure has proven to have self-closing properties that prevent fish escape. 
More than 20 years lifespan
The Polarcirkel EcoNets is made from very strong but light weight PET and has a 20-year lifespan. The nets can also be used as rock slide nets.
Withstands rough conditions
The Polarcirkel EcoNets are made for rough, daily use, from very strong but light weight PET.
Effective escape prevention
The EcoNet has some superior characteristics, including: being virtually escape proof and will prevent species like cod who often can damage regular nets.
Easiliy handled
EcoNet can almost be handled in similar ways as a nylon net. This includes drying up during harvest, fastening to the cages or attaching sinker tubes.
Suits circular and sqare cages
The upper section have vertical walls with a 1 m jump-net up top and the bottom is normally cone shaped.
Predator protection
The EcoNet is predator proof and are also used as shark nets. The semirigid structure will keep the net shape intact.
If overloaded, EcoNet stretch about 60-70% before it finally breaks.
In comparison, nylon stretch about 40% before it breaks.
The shape of the EcoNet wire mesh is designed to remain intact if a single wire is cut. This means the mesh will remain stable and the shape intact with minimum negative effect of the strength of the net cage structure. The Polarcirkel EcoNet is made from very strong but light weight PET, (Polyethylene Terephthalate).
