The escape-proof semi-closed fish cage with deep skirts keep 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 fish farming volume can be divided into adjustable “pieces of pie” that allow for sorting, starving 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 2021.

The Aquatraz technology is patented.

Aquantum Leap is a groundbreaking project that consists of two different closed fish farming systems, Aquantum 500K, the world’s largest fish farm, holds 500,000 m3. Aquantum 12K consists of several fish 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 delivery of fish. They can be operated in 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 fish 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 lifting systems based on compressed air.

The Aquasafe fish farming system has many uses. It is well suited for post-smolt production, delousing, regular fish farming of adult samlmon 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.

Seafarming Systems develops both closed and semi closed fish farming systems. They prevent water from the upper water layers where algae, salmon lice and other microorganisms are located from entering the fish cage. In addition an active water circulation system ensures that plenty of oxygen rich water is obtained from depths free from salmon lice and algae.

Escape-proof fish cages can hold a larger number of fish. Excellent water supply and water circulation allows for higher density of fish in the cage. Water circulators that exercise the fish, excellent water quality and even temperatures can provide faster growth rates. Improved working conditions also contribute to increased productivity. utilizing fish cages that collect sludge, larger areas may become available for fish farming. Fish cages with a larger volume per surface area also contribute to increased productivity. Automated operations due to integrated solutions for sorting, grading, starving and delivering in batches provide flexibility in the production and improved working conditions reducing the need for support vessels.

Cage culture systems with sludge collection solve an important environmental challenge, making more locations available for fish farming and can allow larger fish farms. Sludge collection provides an opportunity for a real circular economy where sludge becomes a resource, as fertilizer and for energy production.

Our closed and semi-closed fish farms are stable steel structures with integrated solutions for sorting and delivery of fish. The platforms provide automated operations and reduced need for support vessels. This means positive changes in working conditions and HSE.

When salmon lice, algae and other harmful microorganisms are kept out of the fish cage, delousing is no longer necessary, plenty of oxygen rich water flowing through the cage, and the water circulators  provide exercise for the salmon, the result can be improved fish health, and faster growth. The fillet quality improves with better colouring, lower fat percentage and firmer fillets.

The Norwegian authorities want a fivefold increase in salmon production by 2050. We believe this is feasible if new sustainable aquaculture technology is developed and implemented. Like the closed Aquantum Leap fish farm, where the Aquantum 500K has a capacity equivalent to 1% of current Norwegian salmon production.

Launching Aquatraz G3

The third generation Aquatraz was launched late April 2020. After the hand-over, the cage was towed to Kipholman location in Nærøy municipality. There it was implemented a further 10 meter of lice skirt, totalling 18 meter of lice skirt. The extension of the lice skirt consists of non-permeable tarpaulin in…

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…
