The solution provides the best possible conditions for growth, regarding good oxygen supply and optimal animal welfare. The development of the EN Tubenet started in 2011.
Following successful small-scale testing at the Institute of Marine Research and largescale testing by fish farmers, Egersund Net received a patent for Tubenet™ in 2014. In the same year, we also received the recognized GSM Innovation Award at the Aqua Vision conference.
The final product is a safe and functional technical solution, reducing attachment of sea lice and preventing escape. When deployed at the proper time, it can reduce cost, due to less or no need for lice removals. In addition, any holes in the upper part of the net caused by flotsam or vessels will not be a concern, as the fish is enclosed at the deeper part of the net.
The concept will also provide the fish farming industry with a new tool for AGD treatment, using freshwater. Resulting in reduction of chemicals used and reduction of stress on the fish.
A smaller buoyant pen is installed and moored inside the main pen. Attached to the inner pen, a tube made of tarpaulin is extended down to a specified depth. A roof of netting is extracted from the baseline of the tube horizontally to the wall of the outer net.
