Sustainable aquaculture

The next ten years will involve major changes in the aquaculture technology to make aquaculture more sustainable. The gap between the desire for large scale growth in production, and today’s challenges with sustainability must be filled with new technology. Seafarming Systems’ mission is to do just that. By using closed and semi-closed fish farms, salmon farming in the sea can be increased, at the same time as the environmental footprint is reduced.

The environmental challenges facing salmon farming, and which must be solved in order to achieve sustainable aquaculture, include escape, salmon lice, suitable areas and sludge collection.

The next ten years will involve major changes in aquaculture technology to make aquaculture more sustainable. The gap between the desire for large scale growth in production and today’s challenges with sustainability must be filled with new technology. Seafarming Systems’ mission is to do just that. By using closed and semi-closed fish farms, salmon farming in the sea can be increased, at the same time as the environmental footprint is reduced.

The environmental challenges facing salmon farming, and which must be solved in order to achieve sustainable aquaculture, include escape, salmon lice, suitable areas and sludge collection.

Protection from salmon lice

Seafarming Systems develops both closed and partially closed cage technology. This means that water from the upper water layers where toxic algae, salmon lice and other microorganisms are located does not enter the fish cage. At the same time, active water circulation ensures that plenty of fresh water is obtained from water depths below where the sea lice are found. The same principle also protects against toxic algae and other harmful organisms in the upper water layers.

Sludge collection and circular economy

Fish cage systems with sludge collection solve an important environmental problem with pollution of the seabed. Cage culture systems with sludge collection solve an important environmental challenge, making more locations available for fish farming and can allow larger fish farms. Large-scale sludge collection provides the opportunity for a true circular economy where valuable minerals 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 becomes unnecessary, it has a positive effect on the fish welfare. When plenty of fresh water flows through the cage, providing a water flow that trims the salmon, the result can be improved fish health and faster growth. The fillet quality also improves, with better coloring, lower fat percentage and firmer fillets.

Safety at work

Our closed and semi-closed fish farms are stable steel structures providing a platform for automated operations and less need for support vessels. This means positive changes in working conditions and HSE.

Increased productivity

Escape-proof cages can hold a larger number of fish. Good water supply and water circulation provide a basis for higher density. Circulating water in the cage trims the fish, more even water quality and temperature from deep water can result in  faster growth rates.  Larger fish farms such as Aquantum Leap with a large volume per surface area also contribute to increased productivity. With sludge collection, fallow time can be reduced. Automated operations with integrated solutions for sorting,  starvation and delivery in batches provide flexibility in the production and improved working conditions.

Economy of scale

Seafarming Systems algins with the UN’s sustainable development goals to increase sustainable  seafood production and take care of our oceans and their biodiversity. We have responded to the Norwegian authorities goal to increase Norwegian seafood production to fivve million tonnes by 2050 by developing sustainable fish farming systems. Such as the closed aquaculture facility Aquantum Leap, which has a production capacity ofup to 33.000 tommes per year. Only 40 Aquantum Leap plants, is required to double the current Norwegian prodution.
