The aquaculture industry has long sought sustainable and efficient methods to enhance the welfare and productivity of farmed salmon, a key component of global seafood consumption. Recently, a pioneering study conducted by Norwegian researcher Tarald Kleppa Øvrebø has brought semi-closed containment systems (SCCS) into the limelight, showcasing their substantial benefits over traditional open net pen farming for post-smolt salmon. Øvrebø's thesis, 'Growth performance and welfare of post-smolt (Salmo salar L.) reared in semi closed containment systems (S-CCS) - a comparative study', presents compelling evidence on the advantages of SCCS in salmon aquaculture.
