Researchers at the University of Bergen (UiB) have launched FishMet, an early-stage proof-of-concept that turns decades of marine physiology and behavioural research into practical tools for aquaculture. The project uses digital twin models to test smarter, more sustainable fish-feeding strategies. How the Digital Twin WorksFishMet simulates appetite, digestion, metabolism and growth by integrating biological and environmental data (e.g. It then estimates feed intake, gut transit, growth rates, feed conversion efficiency and even stress or motivation indicators. While still a proof-of-concept, FishMet shows how university research – supported by innovation partners such as VIS – can progress towards real-world applications in sustainable aquaculture.
