Aquantum 500K is probably the world’s largest planned closed fish cage. It has a diameter of 120 m and a depth of 60 m. Aquantum 500K holds 500,000 m³, and one 500K corresponds to 1% of the total salmon production in Norway today. All operations are automated and integrated into the steel structure. The volume can be sectioned into three adjustable parts. These sections can be sealed apart, or separated by nets that allow water to flow through. These possibilities for sectioning effectively provide opportunities to sort, starve, process and deliver fish. Sludge is collected by sedimentation and transported continuously out of each farming cage and processed at the plant. The entire steel structure can be lifted out of water for washing, maintenance and disinfection without the use of service vessels. Aquantum 500K is patented.
closed fish farming system
Aquantum Leap is a closed contaiment fish farming system, consisting Aquantum 500K and Aquantum 12K. The former, Aquantum 500K is a large fish cage for adult salmon, and Aquantum 12K consists of several smaller fish cages gathered in a rigid frame, suited for post-smolt production. Both facilities have solutions for sectioning and sorting of fish and can easily be operated on regular fjord locations fit for fish farming.
Aquantum 12K is a closed containment fish farm for the production of post-smolt where several smaller, closed, liftable fish cages are gathered in a rigid frame. Each cage can be raised separately. The fish farm has the necessary flexibility for the production of post-smolt, which requires increased sorting and moving between the cages. Aquantum 12K is therefore designed with an integrated system for transport between the cages, and to and from a well boat. It is possible to install sorting equipment in this transport system and thus reduce the need for work vessels. The volume of each fish cage can be adjusted steplessly to ensure optimal density in the cage. Water intake is separated from discharge water to reduce potential infection between the cages. Water intake is done from depths from a few meters down to 30 meters, or even deeper if necessary. Sludge is collected by sedimentation and transported continuously out of each farming cage and processed at the plant. Aquantum 12K is patented.
Closed fish farms and sloshing
When a rigid fish cage is closed, the water inside the fish cage is forced to move with the cage. This free liquid surface effect can lead to sloshing. Closed containment fish farms in the sea are significantly different from traditional net pens from a hydrodynamic and construction perspective. This implies significant differences in environmental loads from waves and currents and their effect on the structure.
FHF, the fisheries and aquaculture industry’s research funding, has funded a research project to gain more knowledge about wave loads on closed fish cages. Read more about the research project of FHF and the results here. (only in Norwegian)
A closed fish cage with the same volume as a conventional net pen must be located in a sheltered location to avoid sloshing. To achieve the goal of a sustainable severalfold increase in production, and avoid area conflicts, we must develop rigid closed fish farms that also solve the challenges of sloshing.
Both Aquantum 500K and Aquantum 12K solve the problem of sloshing and will lie stable in all regular fjord locations where there is salmon production today.
Sustainable fish farming and large scale salmon production
In addition to answering the sustainability challenges for cage culture today, Aquantum Leap is also the first fish farming system that embrace large scale production with fully integrated and automated operations. We believe economies of scale is important for the cage culture industry in order to achieve the desired growth.
