Hybrid flow-through system

Technology

We are transferring the best preconditions offered by the sea to farm fish on land. Location, technology and industrial/technological expertise form the basis for our plans to achieve a sustainable annual production of 36 000 tonnes of salmon.  

30-35% fresh seawater intake reduces complexity and biological and technological challenges.

Reduces risk at low cost

Hybrid flow-through system (HFS)  

Our fish farm utilises a hybridflow-throughsystem (HFS) delivered by Norway’s Artec Aqua to achieve a water economy with about 65 per cent reuse and 35 per cent new supply in the form of filtered fresh seawater. 

This solution ensures controlled and optimal growth conditions, eliminates the risk of parasites and limits the threat of infection. 

A controlled production environment, combined with minimal handling of the fish, improves the growth rate as well as salmon health. In addition, our environmental impact will be reduced through waste-water treatment and reuse of marine resources. 

OUR TECHNOLOGY EXTENDS THE OCEAN POTENTIAL

Global scaling 

We have entered into an investment agreement with South Korea’s Dongwon Industries, one of the world’s leading seafood companies. Plans involve us establishing a partnership to build a fish farm on land in South Korea, utilising our chosen technology from Norway’s Artec Aqua. 

We will also jointly assess future opportunities for scaling similar projects in other Asian markets as well as in North America. Our global expansion plans in the medium and long terms involve a total production of about 70 000 tonnes per annum. 

30-35% FRESH SEA WATER

Reduced complexity gives fewer biological and technological challenges 

Our choice of technology is based on substantial supplies of fresh seawater. It ensures the best possible water quality for the fish while involving very limited operational and biological risk, and is cost-effective in terms of both investment and production. 

Utilising the hybrid flow-through system (HFS) minimises the biological risk of farming salmon on land. 

The facility we are installing will mean that about 35 per cent of water in the farm at any given time comprises clean and fresh seawater, while roughly 65 per cent can be reused. 

A recycling/reuse factor with around 35 per cent clean and fresh water eliminates the need for a biofilter, which in turn reduces both the space required and costs. 

We will be utilising known technology to disinfect the intake water, including filter solutions as well as ultraviolet (UV) to minimise bacterial and viral pathogens.

This avoids complex challenges which can arise with higher reuse rates which require biofilters. It provides salmon in the farm with optimal conditions for growth, health and welfare.

SEVERAL ADVANTAGES

Each tank is a defined biological zone 

We minimise the risk of infection being transferred to other tanks in the farm by making each of them a defined biological zone. In other words, fish and water in one tank are not shared with other tanks. 

One tank corresponds to a single biosecure space. That reduces of the risk of pathogens establishing an internal strain in the tank environment, and being transferred between tanks. 

Separate fish tanks make it easier to clean and disinfect them when fish are to be moved within the farm. 

In addition to increasing biological security, this reduces complexity in the facility, makes it simpler to service, and minimises the risk of consequential technical errors. 

 

BENEFITS

Optimal balance between risk and cost 

The hybrid flow-through system (HFS) offers the best combination between risk, Capex and cost profile for salmon farming on land. 

Utilising the HFS with reuse eliminates the need for cost-driving biofilters and thereby reduces the space required. That in turn cuts capital costs compared with other land-based aquaculture solutions. 

The energy system, which is designed to maintain a water temperature of 14°C in the first production phase and 12°C in the last, has a very high performance in relation to the energy consumed. It ensures high and stable temperatures, which contribute to increased growth. 

We expect operational risk to be substantially lower than with a pure recirculation aquaculture system (RAS). A steady supply of large quantities of fresh seawater makes the HFS less complex for ensuring optimal water quality, that contributes to superior product quality.
