Challenges in biosecurity for aquaculture  

Disease outbreaks and parasite infestations remain major challenges for aquaculture, affecting fish health, welfare, and profitability. With increasing regulatory pressure and consumer scrutiny, effective biosecurity and sea lice management are essential to safeguard fish health, reduce disease outbreaks, and promote sustainable aquaculture operations.  

DNV helps aquaculture producers implement robust protocols to manage biological risks, improve operational efficiency, and meet regulatory and market requirements. 

How our biosecurity services support you  

DNV provides risk-based biosecurity and sea lice management services, including tailored biosecurity plans, vessel inspections, delousing evaluations, and support for coordinated area cooperation.  

• Biosecurity management: DNV assists in developing and implementing tailored biosecurity plans. These plans are aligned with national standards and global best practices to reduce the risk of disease introduction and spread. 
• Biosecurity inspection of aquaculture vessels: We perform thorough inspections of well boats, workboats, and support vessels to assess their compliance with biosecurity protocols, ensuring vessels do not act as vectors for pathogens and parasites. 
• De-lice removal operations: Our experts evaluate and verify the effectiveness of de-licing systems and procedures, ensuring minimal stress to fish while achieving targeted parasite control. 
• Management of area cooperation: Facilitating cooperation across farming sites, we help coordinate shared biosecurity zones, treatment timing, and movement restrictions to increase regional biosecurity effectiveness.
