Aquantum Leap – closed containment fish farming systems
Aquantum Leap is a fish farming concept consisting of two complementary closed containment systems. Aquantum 12k is optimized for post smolt production and Aquantum 500k for larger fish. Aquantum Leap represents a quantum leap in fish farming. Closed containment, large scale production and automated operations is a reality very different than fish farming of today.
Aquantum 12k – closed containment system for post smolt production
Aquantum 12k is a closed-containment system (ccs) consisting of several smaller closed containment fish cages assemblied in a stiff frame. Each cage can be lifted separately. Post smolt production has a higher demand for grading and transport of the fish between the cages. 12k is therefore designed with an integrated system for transport of fish between the cages, and to and from the well boats. The same system allows for grading machines to be installed, reducing the need for support vessels. In order to ensure an optimized density of fish, the volume of each cage can be steplessly adjusted during normal operation. Intake and outlet water is independent for each cage, reducing the risk for cross contamination between the cages. The water intake depth is adjustable from a few meters up to 30 meters, or more if needed. Feces are collected by sedimentation and continuously transported out of each cage, before being processed at the plant. The Aquantum 12k
is patent pending.
Aquantum 500k – closed containment fish farming systems
Aquantum 500k is the world’s largest fish cage planned, with a diameter of 120 m and a depth of 60 m. It’s volume is 500,000 m³. All necessary operations are automated and designed as an integrated part of the structure. The volume can be sectioned in three adjustable bodies. These sections can either be sealed off from each other, or separated by an open net allowing water to flow between the sections. This is a unique feature allowing for efficient grading, starving, treatment and delivery of fish. Finally the whole cage can be lifted out of water allowing for cleaning and maintenance of the complete cage, without the need for external support vessels. The Aquantum 500k is patented.
Sustainability and large scale production
In addition to answering the sustainability challenges of the industry today, it is also the first fish farming system that embrace large scale production with fully integrated and automated operations. We believe this is important for the industry in order to achieve the desired growth.
Closed containment – the future of fish farming?
Closed containment systems surely a party of the future of fish farming, but they are not yet a fully viable alternative. Read our article responding to Trudeau and his liberal party aim for closed containment systems in West Canada and the response from the fish farming industry.
Closed containment fish farming systems and sloshing
The Aquantum Leap technologies have another important and unique feature. They both handle waves so they avoid sloshing. Closed-containment systems (ccs) like Aquantum Leap face different challenges than open net pens. When the waves move the closed container, the waves within the container can become greater than the waves without. This resonance effect is particular intense when the wave length equals the diameter of the fish cage.
This means that closed containment systems that are of similar size as conventional net pens can only operate in calm waters. The Aquantum 500k solve the challenges of the free surface effect by its large size. This ensures that it will remain still also on more exposed location. The Aquantum 12K solve these challenges by having a flexible bottom.
In Norwegian only, unfortunately, but here is more information on a research project investigating the free surface effect on closed containment systems.
