Norwegian researchers develop digital twin model to optimize fish feeding.
Ivar Rønnestad and Sergei Budaev developed a proof-of-concept using digital twin models to explore smarter, more sustainable fish feeding strategies.
Led by University of Bergen (UiB) professor Ivar Rønnestad and researcher Sergei Budaev from the Department of Biological Sciences, FishMet is an early-stage proof-of-concept venture that is exploring how years of marine physiology and behavioral research can be translated into tools for the aquaculture sector.
FishMet originated from a collaboration between UiB researchers and Vestlandets Innovasjonsselskap (VIS). The initiative centers on a digital twin model for precision aquaculture feeding strategies, aiming to help salmon and trout farming operations optimize feeding, reducing waste and improving fish welfare. Although still at a low Technology Readiness Level (TRL 5), the concept has been made available for exploratory licensing opportunities through VIS.
