For the fish to thrive, the facility must be designed to allow the salmon to move over relatively large areas and to behave as naturally as possible. The basin structure provides good living conditions for the salmon. The installation cannot have sharp edges or comprise materials that are harmful to the fish, and it must be designed to protect the fish as far as possible from other animals.
The basin will be a floating, closed production unit measuring 39 x 117 meters in reinforced concrete for salmon farming. Seen from above the basin looks like a sports stadium or athletics track – hence the name (stadion is the Norwegian word for the stadium). The objective of the facility is to reduce or eliminate problems with salmon lice, fish escape, disease, and algae, and to collect the majority of sludge, which mainly comprises feed residue and fish feces. The objective is to develop new technology for the production of salmon, providing optimal conditions for the fish by means of control of water flow and water quality, and at the same time to fulfill new sustainability objectives by reducing or eliminating problems involving salmon lice, fish escape, disease, and algae.
