In the 1960ties the Grøntvedt brothers and Tor Mowincel was the first to prove that it was possible to do farming in sea water. Arne Ratche produced the first successful sea water cages.
Later Professor Trygve Gjedrem and Harald Skjervold together with their co-workers Arne Kittelsen, Vidar Vassvik and Terje Refsti at the Norwegian University of Life Science began their basic work by transmitting knowledge form animal husbandry to seafood farming. The real start for Norwegian sea farming was at the Akvaforsk station in Sundalsøra the 8th of March 1971, when the first group of salmon for breeding was carried out and tamed successfully.
