The escape-proof semi-closed cage with deep skirts keeping sea lice out, provides an excellent stimulating environment for the fish, with abundant water exchange and protection against salmon lice. Aquatraz can be lifted completely out of the water for washing, disinfection and maintenance using the specially developed lifting system. The farming volume can be divided into adjustable “pieces of pie” that allow for sorting, starvaing and delivery  in batches, without raising the cage. Aquatraz has been developed under the scheme with development permits together with Midt-Norsk Havbruk, and the latest generation will be available to a group of Norwegian fish farmers from the autumn of 2020.
Aquatraz technology is patented.

Aquantum Leap is a groundbreaking project that consists of two different closed fish farms. Aquantum 500K, the world’s largest fish farm, holds 500,000 m3. Aquantum 12K consists of several cages gathered in a rigid frame, suitable for post-smolt production. 12K and 500K each have their own unique lifting system that can lift the fish farms completely out of the water. The lifting systems simplify washing, disinfection and maintenance. In addition, the facilities can be towed to new locations in an elevated position. Both facilities have built-in solutions for sectioning, sorting and delivering fish. They can be operated on the majority of fjord locations where salmon is produced today, and each has its own solution to prevent sloshing. The Aquantum technologies are patented.

Aquasafe is a closed cage in steel with sludge collection. In addition to preventing escape, the spread of sea lice and disease, it eliminates pollution of the sea and seabed. The fish cage can be lifted completely out of the water using a lufting systems based on compressed air.

Aquasafe has many uses. It is well suited for post-smolt production, delousing, regular farming and as containment before slaughter.

The unique construction and assembly method used for Aquasafe makes it a particularly cost-effective closed fish cage. The Aquasafe technology is patented.

Seabased closed containment systems

A couple of weeks before election day in Canada, Justin Trudeau’s Liberal party expressed: “In British Columbia, we will work with the province to develop a responsible plan to transition from open net-pen salmon farming in coastal waters to closed containment systems by 2025”. The British Columbia Salmon farmers Association…
