Summary
Since November 2017, mass mortalities of larvae of bay scallop (Argopecten irradians) were reported in hatcheries located at the southern area of Republic of Korea. Over 90% of larvae aged 5 to 10 days sank to the bottom of the tank and died. The hatcheries could not produce spat and thus artificial seed production industry incurred huge losses. We identified Ostreid Herpesvirus‐1 μVar (OsHV‐1 μVar) associated with mass mortality by PCR, sequencing and transmission electron microscopy (TEM). All the samples were positive for OsHV‐1 μVar with 99% sequence identity to previously reported OsHV‐1 μVar sequences. Partial sequence of ORF‐4 of OsHV‐1 detected in this study was more closely related to sequences isolated from Europe. This is the first report to confirm the mortality caused by an OsHV‐1 infection in the bay scallop.
