Utvikling og optimalisering av teknologier for kontroll og håndtering av off-flavor i RAS

Offentlig prosjektsammendrag

Several countries, including Norway, are promoting land-based recirculating aquaculture systems (RAS) to expand aquaculture while reducing environmental impact—critical if land-based farming is to reach 30% of global production by 2030 amid increasing water scarcity. However, profitability is challenged by off-flavors (geosmin, MIB) that spoil fish taste and cause major financial losses. Current mitigation, depuration in flow-through clean water for 10–14 days is water & cost-intensive. This project aims to develop off-flavor mitigation strategies for commercial-scale RAS and depuration systems. AOPs will be tested for off-flavor removal in Atlantic salmon, alongside depuration modeling. The project will: study occurrence and controlling factors (WP1), characterize responsible bacteria (WP2), assess mitigation technologies (WP3), optimize parameters via pilot trials (WP4), and implement validated solutions in full-scale RAS (WP5–6), ensuring sustainable production of high-quality fish.
