CMS: The Silent Killer

How does a disease you can’t see, and often don’t even know is there, cause some of the most expensive losses in salmon farming? In this week’s episode, we examine Cardiomyopathy Syndrome (CMS), a viral heart disease that’s been quietly impacting farms for decades but is now forcing its way into the spotlight. From the biology of Piscine Myocarditis Virus to the real-world costs seen in recent Scottish outbreaks, we explore why CMS is so hard to detect, why it’s not on the official notifiable disease list, and what the latest science says about prevention, from genetics to nutrition.
