Extract from the current Monthly Report from VRFish:
Quote:
The Victorian Abalone Divers Association (VADA) organised for commercial divers to locate the abalone viral ganglioneuritis (AVG) front in early April 2009. All abalone at Rotten point are strong and healthy and there is no signs of the AVG Virus at that location. It appears at this stage that the virus has not been able to cir(edited)vent the sandy area to Rotten Point naturally. It is still of major concern that human activity will transport the virus over the sand areas and it has remained active in the White Cliffs area since November, 2008.
The active AVG front was located in essentially the same area as reported on in late February 2009. There appears to have been minimal movement further east along the Whitecliffs area. Samples have been taken and forwarded off for testing. At the same time as locating the virus front the divers trialled a new survey method for the assessment of AVG viral impacts on the abalone at specific locations.
The development of this method assesses the current live animals at a location as well as the sick and dead animals, etc. The survey showed that the mortality impacts at the surveyed sites were up to 70% of the abalone at those locations. It is intended to do further work to further refine the method. There have been no further reports of the AVG virus front having moved further west than Cape Bridgewater since December 2007.
