Abstract

Cyprinid herpes virus 3 (CyHV-3) is a significant threat to the production of common carp and koi, resulting in high mortality rates and posing a risk to the long-term sustainability of carp aquaculture. The presence of this disease in Iran has been confirmed by the veterinary organization and reported to OIE, with evidence suggesting its presence since 2021 in Iranian Koi and carp farms. Given the economic importance and rapid spread of CyHV-3, this review aims to provide a comprehensive summary of the current knowledge and research on the virus and its disease in Iran and worldwide.  The fish farmers and authorities in the country need to take necessary measures to prevent the spread of the disease and mitigate its impact on the aquaculture industry.
