Prevents salmon lice and escape
Seafarming Systems develops closed and semi closed cage culture technology. All systems have in common that water from the upper layers where harmful algae, salmon lice and other microorganisms are located, are kept out of the cage, while deep water is lifted into the cage and circulated in the cage. The cages are built in steel which provides a stable platform as well as securing the salmon within the cage and preventing escape and predator attacks.
Sludge collection & circular economy
Fish cage culture systems with sludge collection solve an important environmental problem an it provides an opportunity to use fjord locations that are currently not suitable due to weak currents. Available areas for farming will increase substantially and production can be multiplied many times over. Sludge collection also provides the opportunity for a genuine circular economy where valuable minerals such as phosphorus can be recycled and sludge becomes a resource, such as fertilizer and biogas.
Improved fish welfare and fillet quality
When salmon lice, algae and other harmful microorganisms are kept out of the cage, and delousing is no longer is necessary, it has a positive effect on fish welfare. With plenty of fresh water flowing through the cage, and the water flow that exercise the salmon, the result can be improved fish health and faster growth. The fillet quality also increases, with better colouring, lower fat percentage and firmer fillets.
Escape-proof fish cages can hold a larger number of fish. Excellent water supply and water circulation provide a basis for higher stock density. Larger cages with higher density, more fish per cage, automated operations and without the need for delousing result in greater productivity. With sludge collection, fallow time can be reduced.
Economy of scale
Seafarming Systems align with UN’s sustainable development goals by developing fish farming systems that facilitate large scale growth in sustainable seafood production. Like the closed aquaculture facility Aquantum Leap. Salmon is a healthy source of proteins that can be produced in an sustainable manner, while taking care of our oceans and their biodiversity.
Safe working conditions
Our closed and semi-closed fish farms are stable steel constructions with integrated solutions for sorting and delivery of fish. It provides simpler and safer automated operations and reduces the need for support vessels. This also result in improved working conditions and HSE.
