Non-lethal diagnostic indicators for better decision support in the aquaculture industry

The rise in handling‑intensive operations to combat salmon lice is contributing to higher mortality rates among treated fish toward the end of the production cycle.

This represents an ethical concern, leads to substantial financial losses and negatively impacts both the reputation and sustainability of the aquaculture industry. Current knowledge is not sufficient to address the health and welfare challenges in farmed salmon that must be resolved for the industry to grow responsibly. Robust decision‑support tools are essential for assessing fish health and welfare on a sound scientific basis and for ensuring high‑quality strategies and management decisions.

The project will develop new diagnostic tools based on molecular assays, ultrasound technology and camera‑based behavioural monitoring. Together, these technologies will provide more accurate health assessments and enable targeted, effective measures to reduce mortality risks associated with handling operations.
