AKVA group ASA established ATLANTIS SUBSEA FARMING AS in collaboration with Sinkaberg-Hansen AS. The company has carried out large-scale development and testing of submersible salmon farms. After being granted a development permit, the company conducted extensive testing and documentation work from 2014 to 2021. The project has now been completed and AKVA group ASA owns the rights to the technologies that were developed. Customers and other partners interested in Atlantis are requested to get in touch with the contact persons mentioned at the bottom of this page. Experience from the project shows that fish behaviour and welfare was good and that the fish quickly learned to use the air dome to fill their swim bladders. The results show that it is entirely possible to avoid lice infestation in submerged cages provided that the fish are as free of lice as possible when exposed, the cage is brought to the surface as little as possible (requires the use of lice monitoring cameras) and that the entire locality has deep farming solutions. Technical solutions ■The entire structure is lowered to below 20 m and only buoys are visible on the surface. ■A common frame mooring with enlarged surface bends ■The floating cage has no polystyrene and has an accompanying bottom ring ■The net is a regular nylon net with Lift Up for dead fish collection ■A net roof is "attached" to the floating cage and an air dome is attached to the middle of the net roof that provides the fish with air via an air pocket. ■It is fed with water in points around the air dome
