The recent emergence in Australia of abalone viral ganglioneuritis (AVG) caused by abalone herpeslike virus (AbHV) is recognised as a major commercial threat to both the wild capture and the fledgling aquaculture industries, and an environmental threat to wild populations in general.
Results from recent research demonstrated that abalone from various sites along the Victorian coast-line that had experienced outbreaks of AVG remained susceptible to infection and disease. The mature abalone that were sourced from these areas are presumed to be survivors from the previous disease outbreaks and the juvenile abalone are presumed to be the progeny of these survivors.
Neither groups demonstrated any resistance to reinfection and appeared to be as susceptible as naïve counterparts sourced from a farm that had no history of AVG.
This knowledge will assist industry and regulators manage the wild abalone fishery into the future.
