What is the future of fish farming?
We anticipate great changes in the near future of fish farming. The Norwegian government have deemed a production growth of 500% by 2050, desirable. Despite the ambitious goal, there have been little growth the last few years because of sustainability challenges. Escaping salmon, sea lice and seabed pollution are environmental impacts that must be addressed. To overcome these challenges and enable growth of this scale, quite radical technology development is needed. That’s what Seafarming Systems aims at. We will realise the desired, sustainable growth in fish farming, by offering cutting edge fish farming technology. Technology that tackle the sustainability challenges, deal with the negative environmentally impacts and enable growth through large scale, automated, cost-effective fish farming systems.
Sea lice, algae and disease
Our fish farming solutions are closed containment systems (ccs) or semi closed containment systems (sccs), with water intake solutions that ensure that no water is taken in from the upper layers where lice, algae and unwanted microorganisms lives.
Escaped salmon and safety
Our closed and semi closed fish cages safeguards your fish and prevents escape. These steel cages have lifting systems in place, which safeguards your salmon during operations like delivery of salmon. In addition, this creates stable and safe working platforms, protecting workers as well as fish. Previous challenging heavy lifting operations are automated.
Fish farming locations
Available fish farming 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, if it’s not collected. Waves and rough water also place limits on salmon 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 seaside. Our closed containment systems come with sludge collection, and water intake solutions. This increases the number of locations available for fish farming dramatically. Volume efficient fish cages like the Aquantum 500k matches the volume of 14 conventional open net pens, while only requiring 1/10 of the surface area.
Solutions for sludge collection are possible for all our fish farming Aquatraz and Aquajet Flex can be delivered both with and without sludge collection. The closed containment systems like Aquantum Leap and Aquasafe have integrated sludge collection.
Large scale production
In order to reach the desired 500% growth by 2050, the fish farming technology need to move towards large scale and automated production.
Closed containment systems and sloshing
When we use seabased closed containment systems, we need to take into account the free surface effect. When waves move a water filled closed container the waves within the container can exceed the waves without, and sloshing occurs. The effective mass of the moving water inside the fish cage must be included.
