Description du projet
Améliorer la pisciculture grâce à la technologie des systèmes d’aquaculture en recirculation
Les systèmes d’aquaculture en circuit recirculé (RAS) sont une nouvelle méthode d’élevage des poissons. La technologie RAS permet d’élever des poissons dans n’importe quel climat et emplacement, quelle que soit la température extérieure. C’est une bonne nouvelle puisque l’aquaculture est aujourd’hui le secteur de l’alimentation animale qui connaît la croissance la plus rapide. Dans ce contexte, le projet RASOPTA, financé par l’UE, développera de nouvelles technologies visant à améliorer la qualité de l’eau en réduisant les nutriments et en contrôlant l’abondance des bactéries et parasites nuisibles. Le projet concevra également des méthodes sensorielles et instrumentales pour déterminer les conditions d’élevage idéales pour un goût optimal. Il développera également une puce à base d’ADN pour avertir des problèmes émergents dans le fonctionnement du RAS.
Objectif
Globally, aquaculture is the fastest-growing animal food sector and today almost half of the World´s consumption of all fish products originates from aquaculture. However, high water consumption and nutrient release from fish farms cause environmental and public concern. This has led to development of fish breeding in systems with water recirculation, named RAS. RAS technology reduces the water consumption, but reuse of the water causes problems with respect to maintaining a high water quality, even when various water treatment approaches are used. In the RASOPTA project, new technologies for improvement of the water quality by reducing nutrients, controlling abundance of harmful bacteria and parasites, will be developed. To ensure a high welfare of the fish, stress level of the fish will be monitored, and for biosecurity reasons, potential spreading of pathogenic virus and bacteria from RAS farms will be examined. A major concern in RAS is microbial production of earthy off-flavours that accumulate in fish and reduce their consumer attractiveness. Occurrence of these microbes will be analysed to develop mitigation procedures. To ensure marketing of tasty fish with RAS technology, sensory and instrumental methods will be applied to determine ideal rearing conditions for optimum taste. For prediction of water quality and health issues in RAS, a DNA-based chip will be developed to allow an early warning of emerging problems in operating RAS. These research goals will be accomplished through interdisciplinary and university-industry driven research training by 8 universities, 3 research institutes and 8 companies. By combining new approaches within microbial ecology, molecular biology, bioinformatics and analytical technologies, the project will deliver solutions to remove barriers that restrict expansion of the innovative and highly efficient RAS fish production.
