Land-based fish production is optimised with next generation digital recirculating aquaculture systems (RAS). DIGIRAS focuses on developing digital solutions for parameters and processes in RAS, which in turn will lead to more sustainable production under special attention to fish health and welfare.


DIGIRAS is a project aiming to close the knowledge gap with digitalisation, supported by ERA-NET BlueBio cofund over the period of three years with the total funding of 1,94 million euros, shared between 11 collaborators from 5 different European countries. It involves four different RAS farms cultivating five economically important species. Two of the RAS farms are located in Norway, cultivating Salmo salar (Atlantic salmon) and Salvenilus alpinus (Arctic charr). One farm is located in Greece cultivating two species, Sparus aurata (Mediterranean seabream) and Dicentrarchus labrax (Seabass). Finally, the last farm is located in Germany cultivating Seriola lalandi (Yellowtail kingfish).

The project is organised in seven R&D and two managing work packages, each tackling specific topics in relation to the main aim. The following major objectives in DIGIRAS reflect the multidisciplinary character of the project:

  • Detailed analysis on microbial communities in RAS and on the cultivated fish
  • Development of new high-resolution and ultra-sensitive biological and chemical sensor technology for RAS
  • Systematic high-resolution analysis of chemical water quality parameters in RAS
  • Development of innovative methods for real-time monitoring of fish welfare
  • Monitoring fish health in operational and experimental studies
  • Improving water quality in RAS using innovative treatment strategies
  • Integrating multidisciplinary data and development of decision support and management tools for RAS

Partners from Norway, Finland, Germany, Portugal and Greece are responsible for the R&D part of the project. SINTEF Ocean (Norway) and Bielefeld University (Germany) are focusing on high resolution microbiological monitoring, with development of quick assays for detection of species of interest. Lappeenranta University of Technology (Finland) and International Iberian Nanotechnology Laboratory (Portugal) are focusing on quick and ultra-sensitive systems for chemical water quality analysis, as well as on efficient water purification systems for improving water quality in aquaculture. University of Patras (Greece) and SINTEF Ocean (Norway) focus on methods for monitoring of fish health and welfare, including classical methods, but also real-time monitoring supported by machine vision and deep neural networks. Finally, successful integration of all collected data from different work packages is facilitated by Norwegian University of Life Sciences (Norway).
