New closure to help keep abalone disease out of NSW

A new closure has been put in place and it is now illegal to use abalone gut as bait or burley, either recreationally or commercially, for the taking of any fish in all waters of NSW.

Why has this new closure been introduced?
This closure has been declared to protect abalone stocks from a virus known as abalone viral ganglioneuritis (AVG). This is because:
- The use of abalone gut as bait carries a high risk of introducing AVG into NSW abalone populations.
- Research has shown that the AVG virus can survive freezing to -80ºC, and it is highly unlikely that it will be killed by the harvesting and storage process.
- AVG can spread through the water column so infected bait does not need to come into direct contact with live abalone for the virus to be transferred.
- If AVG is introduced into NSW, it is likely that the impacts would be devastating to the NSW abalone population.
What is AVG?
AVG is a viral disease which affects the nervous system of abalone. It is caused by a herpes-like virus and results in curling of the foot, swelling of the mouth, weakness and death. The disease is spreading from where it was first detected in the coastal waters of south west Victoria. It affects both blacklip and greenlip abalone and hybrids of the two. AVG has no known effects on human health.

The impacts if AVG were to enter NSW
If AVG was introduced into the NSW population of abalone, extensive losses would be expected. AVG has caused massive losses of abalone in Victoria, with up to 95% mortality in certain areas in the last two years. NSW populations of abalone are already affected by stock decline and another disease, Perkinsus.
Alternative baits
Several alternative baits are available to fish for the species normally targeted with abalone gut. These include prawns, pippies, green weed, cunjevoi, crabs and bread.
Please respect the closure
By respecting the ban on taking fish with abalone gut, fishers will be helping protect abalone stocks for future generations. NSW DPI recommends that abalone gut already purchased by fishers be disposed in landfill.
What else is NSW DPI doing?
In addition to the new closure, Standard Operating Procedures (SOPs) have been developed for commercial abalone divers to promote best practice and hygiene protocols. This is to reduce the risk of aquatic disease outbreaks such as AVG and Perkinsus.
Further SOPs will be developed as required in consultation with other states and industry.
