The future of sustainable aquaculture
Protection from sea lice
Large scale production
We expect great changes in the aquaculture industry the next decades. The Norwegian government have deemed it desirable with a production growth of 500% by 2050, from 2012. Despite of the ambitious goals, there has been little growth the last few years because of sustainability challenges with, escape, lice and lack of sludge collection. To overcome these challenges and enable rapid growth, quite radical technology development is needed. That’s exactly what Seafarming Systems aims at. We will realise the desired, sustainable growth in fish farming, by offering cutting edge technology. Technology that tackles the sustainability challenges and enable rapid growth through large scale, automated, cost-effective fish farming systems.

Protection from sea lice
Our fish farming solutions are closed-containment systems (ccs) or semi-closed-containment systems (sccs), with energy effective water intake solutions that ensure that no water is taken in from the upper layers where lice, algae and unwanted microorganisms lives. The Aquatraz G4 have a watertight lice skirt of 22,5 meters and it’s water exchange solution will exchange the entire water volume minimum 4 times per hour., ensuring consistent good water quality, also at less than optimal locations.
Escape & safety
Our closed and semi-closed steel cages that safeguards your fish and prevents escape. The steel cages are stable and safe working platforms, protecting workers as well as fish. Wutgh safety against escape in place and ensured good watr quality due to the water exchange system our fish cages can hold a higher number fish and higher density. Aquatraz has received dispensation from the Norwegian authorities to hold up to 45 kg/m3, almost double the regular density of 25 kg/m3.

Available locations is a challenge in several aspects. Open net pen salmon farms require locations with a strong enough current to ensure fresh and oxygenated water, and to disperse sludge. Waves and rough water also place limits on fish farming. Calm waters close to land is also sought after for recreational purposes, and so it can create conflict of interest for different users of the sea. Our closed solutions come with sludge collection, and water intake and flow solutions. This increases the sites available for fish farming dramatically. The Aquantum 500k matches the volume of 14 conventional fish pens, while only requiring 1/10 of the surface area.
Closed fish farms with sludge collection solve an important environmental problem. Sludge collection provides the opportunity for a genuine circular economy where sludge becomes a resource. For that we need large amounts of sludge. In Aquantum Leap, where Aquantum 500K has a volume corresponding to 1% of Norway’s salmon production today, not only sludge collection, but also production of manure from the sludge is part of the project. Sludge collection is also part of the concept for closed holding cages such as the Aquasafe.
