Queensland Aquaculture Industries Federation (Inc) (QAIF) represents the major land based aquaculture sectors in Australia. Members believe that as the industry grows in scale, geographical spread and develops breeding stock re distant from the original wild sector genetics, it is becoming more exposed to risks of biosecurity breakdown. 

An industry workshop was held in Cairns on 5 September 2012.

It was attended by farmers, hatchery managers, university researchers, vets and senior staff from agencies responsible for managing biosecurity at a State and Federal level.  Issues explored included the risks to be managed, response arrangements and on-farm biosecurity protection.

Abstract:

Mortality of farmed triploid Pacific oysters (Crassostrea gigas) associated with Ostreid herpesvirus-1 (OsHV-1) was first recorded in Australia in the Georges River/Botany Bay estuary (New South Wales) in late 2010. Two years later, the first sign of possible inter-estuarine spread was observed when commercial triploid Pacific oysters in the Hawkesbury River estuary, located 50 km north of Botany Bay, were affected by mass mortality.

In Australia, the spread of the ostreid herpesvirus-1 microvariant (OsHV-1 μVar) threatens the Pacific oyster industry. There is an urgent need to develop an experimental infection model in order to study the pathogenesis of the virus under controlled laboratory conditions. The present study constitutes the first attempt to use archived frozen oysters as a source of inoculum, based on the Australian OsHV-1μVar strain.

Abstract:

The microvariant genotype of Ostreid herpesvirus-1 (OsHV-1 μVar) has severely disrupted the production of Pacific oysters Crassostrea gigas in Europe, New Zealand, and Australia since its first detection in France in 2008. The disease occurs in the warmer months, recurs annually, and requires new management strategies. Larvae and spat are the most susceptible life history stages, which poses a threat to hatchery production.

Management of mass mortality events associated with Ostreid herpesvirus-1 microvariant (OsHV-1 μVar) is vital for aquaculture of Crassostrea gigas. As a consequence, the understanding of transmission mechanisms and risk factors enabling husbandry solutions to be developed constitutes an international research priority. In this context, a longitudinal intervention study was set up in Woolooware Bay, Australia, during summer in 2012–2013.

Abstract:

In 2010 Ostreid herpesvirus-1 (OsHV-1) was detected in Australia and had a disastrous impact on Pacific oyster Crassostrea gigas aquaculture and coastal communities. The acronym POMS (Pacific Oyster Mortality Syndrome) was created in Australia to refer to mass mortalities due to OsHV-1. While management of this disease mainly involves active surveillance, rigorous biosecurity protocols and mollusc breeding  programs targeting production of resistant animals, the effects of aquaculture practices on mortality outbreaks are still poorly understood. The present study aimed to determine the effect of growing heights on OsHV-1 associated mortality in C. gigas in Woolooware Bay (Australia) during the summer 2011/2012.

Ostreid herpesvirus-1 (OsHV-1) is responsible for massive mortality events in commercially farmed Pacific oysters (Crassostrea gigas) in Australia, New Zealand, Europe and the USA. Economic losses have been severe in many countries since 2008, associated with a strain known as OsHV-1µ-var. Despite intensive studies of the virus itself, there is almost no information on its detection in natural seawater, how it is spread over wide geographic distance in water or on how it is transmitted from oyster to oyster via seawater.

The Australian prawn farming sector provides significant income to regional economies, particularly parts of Queensland. The entrance of an exotic disease can potentially cripple the industry. Hence, it is prudent to reduce the risks of disease incursion domestically and on-farm. 

Since 2010, a number of disease outbreaks have been reported within the prawn farming industry in South-East Asia. This highlights the importance of biosecurity (the practice of disease prevention and management) within the industry. The summit assisted in raising awareness of exotic diseases and strategies to prevent and control emergency disease events. 

Engagement of the industry for on-going disease surveillance is important. The summit provided further education to improve current practices on-farm to aid in disease surveillance. As the project had an interactive framework, it encouraged industry to help identify areas of improvement in the current system. 

The summit was run on the 31st July 2012, and provided a platform for the collaboration of government workers, farmers, researchers and industry. Approximately 35 people were in attendance for the biosecurity summit, and were provided with case studies and examples of the consequence of emergency aquatic animal disease outbreaks suffered by international industry. The necessity of disease prevention was the focus throughout the summit as the limitations of treatment and control were detailed. Applied prevention measures for Australian farms were highlighted.
