Experts have denied rumours that breeding with foreign abalone started a deadly virus which spread from south-west aquaculture farms to the ocean.

 

Rumours have flowed that the virus was caused at Southern Ocean Mariculture after breeding with Taiwanese or South African abalone to produce higher-quality stock.

 

General manager Mark Gervis said the farm “never had and never would'' breed with exotic species.

 

“The information we have at the moment is that wild-bred stock were collected by the farm and may have caused the disease but it is not definite,'' Fisheries Victoria executive director Peter Appleford said.

 

He said the disease had not been found in those locations.


 

Southern Ocean Mariculture has returned a small number of stock to check the farm has been properly disinfected.

 

Mr Gervis said there was no evidence of the virus at the farm and it was hoped restocking could continue.

 

“We don't know when we will be up and running again... We are waiting on permission to locate stock from other farms,'' Mr Gervis said.

 

Dr Appleford said that during disinfection at Southern Ocean Mariculture no water was discharged into the ocean but the farm had since been discharging water.

 

Coastal Seafarms, at Allestree, has been conducting a similar clean-up program.

 

The ganglioneuritis disease has continued to be found on reefs east of Port Fairy towards Killarney and as far west as The Crags.

 

Crayfish in the area are also feeding on the infected abalone and are refusing to enter lobster pots.

 

Experts have rejected fears of the disease passing on to crayfish.

 

“These sorts of viruses are species-specific. We believe it would be highly unlikely,'' Dr Appleford said.

 

“We've been looking at (cray) stocks and catch rates and we are trying to determine at the moment whether they are getting reduced catch or if they are simply difficult to catch.

 

“This could be because of a variety of reasons such as warmer water or cold water upswell.''
