Tasmania, the source of 25% of the world's wild-caught abalone production, is curently experiencing an outbreak of abalone viral ganglioneuritis. Following on outbreaks in 2008 and 2009, the latest appearance of the disease at Bicheno in January 2011 has lead to the quaranting of land-based culture and processing facilities, as well as closure of the local recreational fishery. Testing is ongoing to determine the extent of the outbreak and the possibilty of infection in the wild population.
For further details, the following links provide in depth information including a time line of the outbreak and a breakdown of the testing programme currently underway:

Experts have suggested that Taiwan's aquatic farmers stop raising a popular type of marine mollusk to eliminate a virus that has nearly wiped out the entire industry.
According to FocusTaiwan, almost all of Taiwan's cultivated abalone (Haliotis diversicolor) have been infected with a virus that has decreased the total harvest by 90 per cent, said researcher Ho Yuan-hsing of the Eastern Marine Biology Research Centre. read more >>>
As a highly valued seafood in Chinese culture, abalone farming has been growing extensively in recent years. The total production increased from 19956 metric tons in 2006 to 42373 metric tons in 2009, with 28.6% increase annually.
Abalone farming mainly distributes in two areas in China: the north coast, including Liaoning, Hebei and Shandong provinces, and the south coast, Fujian and Guangdong provinces. The main culture species are Haliotis discus hannai and Haliotis diversicolor. The obvious change of abalone farming in China in the recent years is that the main abalone farming area shifts from the north coast to the south coast. read more >>>
In 1999 bio-toxins of the type Paralytic shellfish poisoning (PSP) and Diarrhetic shellfish poisoning (DSP) were found in wild and farmed South Africa Abalone.
The main market for South African product is Europe the European Community have imposed stringent (and many might say over the top) food safety standards for abalone product entry in that area. In an attempt to introduce a more reasonable and workable set of standards South Africa applied to Codex, the more superior international standards body, to have a set of standards adopted by the Codex Commission for application internationally.

Some paua news from New Zealand:
The Ministry of Fisheries is reminding paua divers that a new minimum legal size of 85mm in shell length comes into effect tomorrow (1 October 2009) for the Taranaki region. Taranaki paua are naturally small or ‘stunted’ and never reach the minimum legal size of 125mm for paua across the rest of New Zealand, maturing and breeding at a much smaller size. read more >>>
Some Taranaki coastal farmers are considering banning public access across their land in an effort to protect the region's paua stocks. They say they've had a gutsful of watching people returning to their vehicles carrying sacks laden with paua numbers well over the legal limit of 10 per person per day. read more >>>

Abalone, an edible mollusk lined with mother-of-pearl, could flourish in Mindanao due to its warm seas and could potentially become its high-value aquaculture product. Vincent Encena II, specialist of Iloilo-based Southeast Asia Fisheries Development Center Aquaculture Department (SEAFDEC-AQD), said Mindanao could cultivate abalone due to favorable sites, weather and availability of seaweeds. read more >>>
On behalf of all International Abalone Society Members congratulations to Padermsak Jayaraband and his organising committee for the 2009 IAS Symposium in Thailand. The organisation was seamless and the meeting brought together the diverse community of people interested in abalone. A range of quality presentations highlighted the issues facing abalone including changing markets, booming aquaculture, fisheries in trouble, poaching, growing pressure for conservation and restoration. Encouraging was the wide use of abalone as a research model and the fascinating fundamental research unfolding in genetics, molecular biology and physiology. The IAS meeting is undoubtedly a valuable forum for reviewing issues associated with abalone, sharing information and discussion issues and action.
Past-IAS president Peter Cook has sufficient contributions to fill a whole issue of the Journal of Shellfish Research, keeping up the tradition of quality, peer-reviewed proceedings from IAS meetings. In order to encourage membership subscription, the proceedings as well as the powerpoint presentations from the conference will only be available to paid up members.
One of the commitments of the new IAS committee is to facilitate communication and discussion around abalone issues in between IAS meetings. To this end regional representatives were appointed as follows:
Australia - Nick Elliot
Chile - Roberto Flores- Aguilar
China - Kangsen Mai (if available)
Canada - Joanne Lessard
Europe - Gercende Courtois de Viscose
