Biosecurity in RAS (recirculating aquaculture systems) (BRAS)

New knowledge about the sensitivity of pathogenic microorganisms to disinfection measures and survival in RAS will contribute to optimized procedures and practices, and thus reduced mortality and improved fish health/welfare. By identifying where pathogenic microorganisms reside in a RAS and what measure is sufficient for inactivation, appropriate biosecurity strategies can be proposed. This will reduce the risk of infectious diseases, but also contribute to efficient and cost-saving operation of RAS.

New knowledge in this area will also have transfer value to other forms of closed/semi-closed aquaculture (land-based and sea-based) and the wellboat industry. Overall, such knowledge will contribute significantly to a reduced risk of disease outbreaks and thus reduced costs and lead to increased sustainability throughout the industry.
