As global demand for sustainable seafood rises, so does the pressure to find effective, environmentally friendly solutions to persistent health challenges. One of the most pressing issues is the management of bacterial infection such as Yersinia ruckeri, a pathogen notorious for impacting juvenile rainbow trout and other farmed fish. Traditional responses have relied heavily on vaccines and antibiotics but growing concerns about antimicrobial resistance and regulatory restrictions have made these approaches increasingly unsustainable.

Vetagro, an Italian leader in animal biotechnology, in collaboration with Canadian aquaculture CRO Onda, have announced compelling results from a joint research initiative evaluating microencapsulated phytogenics for their efficacy against Yersinia ruckeri—a major pathogen in rainbow trout farming.

In the fast-evolving world of aquaculture, fish health is central to both operational success and long-term sustainability. Diseases, like Cardiomyopathy Syndrome (CMS), that are years away from developing market-ready vaccines, must rely solely on careful biosecurity and surveillance practices to reduce the impact of disease through early detection.
