Sustainable fish farming systems can increase seafaood production while reducing environmental impact.
Aquatraz is one of several types of fish farming systems developed by Seafarming Systems that can contribute to sustainable aquaculture with increase in sea-based fish farming as well as reducing the environmental footprint. It involves both closed and semi closed cage culture systems which:
- protect against algae and salmon lice
- prevent escape
- increase productivity
- provide better fish health and fillet quality
- contribute to a circular economy where sludge is a resource
- automate operations such as sorting and delivery in batches.
Closed containment fish farming systems
Aquantum Leap is a groundbreaking development project that consists of two different closed containment fish farming systems.
Aquantum 500K, the world’s largest planned fish cage, holds 500,000 m3. Aquantum 12K consists of several smaller cages gathered in a rigid frame, well suited for post-smolt production. 12K and 500K each have their own unique lifting system that can lift the facilities completely out of the water. The lifting systems simplify washing, disinfection and maintenance. In addition, the fish cage facilites can be towed to new locations in an elevated condition.
Both fish farming systems have built-in solutions for sectioning and sorting fish. They can operate in almost all fjord locations where salmon is produced today, and each has its own unique solution to prevent sloshing. The Aquantum technologies are patented.
Closed fish cage
Aquasafe is a closed fish cage in steel with sludge collection. In addition to preventing salmon escape, spread of salmon lice and disease, it eliminates pollution of the sea and seabed. The fish cage can be lifted completely out of the water using the integrated lifting system that is based on compressed air.
Aquasafe has many uses. It is well suited for post-smolt production, delousing, farming of adult salmon and for containing salmon before slaughter.
This cage culture system has an unique construction and assembly method that 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. 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.
