Oyster aquaculture contributes millions of dollars to the Washington State economy. But emerging, rapidly spreading diseases such as the ostreid herpesvirus (OsHV-1) call for tools that will enable regulatory agencies and industry to respond effectively to such outbreaks. Towards that, researchers are developing molecular and diagnostic tools and data for early detection of OsHV-1 and its variants. They also will conduct field and laboratory trials to identify which oyster lines grow well when exposed to the virus. And the viral genomes used in infection trials will be sequenced to better understand how such diseases develop and to select resistant oysters.
