The new land-based fishfarm is located in Northern Jutland, Denmark – at Sashimi Royal. It is the first plant built at full scale in Krüger’s groundbreaking Recirculating Aquaculture System 2020 design.
The demand for quality seafood and sophisticated consumer purchasing trends have increased. This, combined with the environmental and financial risks of offshore aquaculture, creates the need for farmers to gain greater control over their operations. Land-based aquaculture is a solution that enables aquaculture companies to reduce risk whilst maximizing profitability.
To meet these challenges, Krüger has designed and delivered process equipment to RAS2020. The Danish Ministry of Environment and Food provides financial support. RAS2020 is a modular, recirculating aquaculture system designed to reduce capital costs, maximize production, minimize operating costs, and improve sustainability. The plant also meets the harsh conditions for water quality. The RAS2020 allows farmers to achieve a farm-to-table strategy by locating facilities on land near key markets. This reduces shipping costs and shortens delivery timeframes, whilst offering consumers a superior, fresher product.
Sashimi Royal is the first company in Denmark to have sustainable land-based aquaculture based on RAS2020. Sashimi Royal’s primary product is yellowtail, a popular product in international sashimi and sushi markets. It is a warmwater fish that can only be farmed in Northern Europe, in specialized on-shore production facilities.
The new RAS2020 solution is an extremely compact, self-contained system with a reduced carbon footprint and reduced costs. Furthermore, it is easy to control, and the production costs per kilogram of fish is almost the same as for ocean-based production facilities.
"We are proud to be the first sustainable, land-based aquaculture in Denmark with almost no impact on the environment. We do not vaccinate our fish and we produce fingerlings ourselves. It is a big advantage that the new RAS2020 solution is extremely compact and manageable. We do not need a large area to have a huge production site. We expect to produce up to 1,200 tonnes of yellowtail a year to be sold all over Europe", CEO Claus Roms explains.
The adjustable water velocity in the two circular tanks in RAS2020 ensures optimal conditions for the fish in the entire water column. It is generated by flow makers, which ensure that the exchange of water in each tank section in less than a minute. The velocity of water is adjusted to the size and species of fish, which gives optimal fish welfare and subsequently high-quality meat. The RAS2020 is well-suited to species such as salmon, kingfish, sea bass, sea bream, trout, pike perch and barramundi.
The compact RAS2020 design allows for the production of the same volume of fish at only half the carbon footprint compared to that of other conventional RAS designs on the market. An advanced control system also ensures that all important parameters such as oxygen, pH, CO2 and temperature are optimal.
