Abalone viral ganglioneuritis


Abalone viral ganglioneuritis (AVG) is a viral disease which affects the nervous system of abalone and results in curling of the foot, swelling of the mouth, weakness and death of abalone.

AVG affects both Blacklip and Greenlip Abalone and hybrids. AVG is not known to occur in wild abalone stocks in NSW, and an AVG outbreak in live abalone tanks at a retail seafood outlet in Sydney NSW was eradicated in 2011. There is no evidence that AVG has any effect on human health.

The community is encouraged to report any observations of sick, dying or dead abalone to the NSW Fishers Watch hotline on 1800 043 536.
