Piscine Reovirus (PRV)

Piscine Reovirus (PRV) is a virus that infects salmon and related fish species. It primarily targets the fish's blood cells and can cause a disease called Heart and Skeletal Muscle Inflammation (HSMI), which damages heart and muscle tissues. While many infected fish show no symptoms, some may experience weakness, reduced growth, or increased mortality. PRV spreads through water and fish-to-fish contact. Monitoring and managing PRV is important for maintaining healthy aquaculture and wild fish populations, as outbreaks can impact fish health and industry sustainability.
