In an industrial area near the port, where tourists are waiting to catch the ferry to Norway, stands a large indiscriminate set of buildings that contains the first recirculating aquaculture system (RAS) salmon farm that has managed to generate positive financial results: Danish Salmon. According to Kim Hieronymus Lyhne, Danish Salmon’s CEO, the country’s RAS roots can be traced back to the 1990s when the eel sector wanted to grow, but needed on-land capacity to do so. As time went on and the farmers kept tweaking and improving their systems, eventually they evolved into the first rudimentary RAS. “I wouldn’t be surprised if the Danish actually invented RAS,” Lyhne reflects.
