Testing retail commodities for the presence of Taura Syndrome Virus and Yellow head Virus I
The Australian prawn farming industry has been fortunate to remain free from many of the serious viral diseases which have decimated prawn farms internationally. It had been free from WSSV until it hit the Logan River farms in late 2016.
Pathways for movement of disease have been described through the movement of commodities destined for human consumption, such as uncooked prawns. Diversion of such commodities through use as bait or berley by anglers has the potential to generate a release pathway that could see these disease enter prawn farms via their intake of water, or through use of wild broodstock who may develop sub-clinical infections. Recent surveys have suggested that recreational angler use of supermarket origin uncooked prawns for bait has increased, even though such commodities are labelled that they are intended for human consumption only, and are specifically not to be used for bait.
Knowledge of the risks associated with uncooked prawn importations will assist the industry in contributing to the review of the Import Risk Assessment of uncooked crustacean which is currently underway. Data from this testing will also assist farmers in relation to making risk based decisions around major capital expenditure on farms to increase biosecurity and surveillance.

Abalone Viral Ganglioneuritis (AVG) R&D Needs Workshop
Determining the susceptibility of Australian Penaeus monodon and Penaeus merguiensis to newly identified enzootic (YHV7) and exotic (YHV8 and YHV10) Yellow head virus (YHV) genotypes
Bio-Security Awareness Workshop
Aquatic animal health and biosecurity are fundamental to a viable aquaculture industry. Although there are many possible providers of information and support regarding biosecurity on farms, and many implications for disease outbreaks for farmers, farmers are generally poorly informed about these matters.
In addition, in the absence of detailed feedback, regulators are unaware of practical issues that may arise in the application of policies and procedures regarding aquatic animal health.
This workshop will provide an opportunity for exchange of information and views regarding aquatic animal biosecurity between farmers and regulators in Qld.
In so doing, it will improve the understanding of aquatic animal biosecurity and lead to improved biosecurity in the Qld aquaculture industry.
Final report
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.
Australian abalone industry emergency disease response awareness workshop
Emergency aquatic animal responses often involve complex, multi-lateral and inter-jurisdictional arrangements, and also can have specific trade and market access responsibilities that need to managed. Part of maintaining Australia's aquatic biosecurity track record is to improve the awareness and preparedness within specific industry sectors. Since 2005 there has been a number of abalone disease outbreaks, which may have potential trade and market access issues. It is critical that the industry nationally take stock and ensure it captures the wealth of lessons that have been learnt, and gain a common understanding of established procedures and responsibilities, especially how government, processing, commercial fishing and farms can best respond to any future outbreaks.

Aquatic Animal Health Training Scheme 2019-2022
While the AAHTS has been in operation for 9 years, there remains a need for the continual education and training of aquatic animal health professionals to enhance their skills across a range of specialist disciplines. Based on the significant outcomes from the previous nine years of the AAHTS, the Department of Agriculture has contributed $75,000.00 (less $7,500.00 (10%) management fee, cash contribution to FRDC) to ensure that the AAHTS continues to be implemented for a further 3-year period (2019/20-2021/22) with matching funding anticipated from the FRDC Aquatic Animal Health and Biosecurity Subprogram. Thus, an application is needed to generate an agreement between CSIRO-AAHL and FRDC for continuation of AAHTS which would be administered as previously, i.e., by CSIRO-AAHL (rather than FRDC) through the FRDC Aquatic Animal Health and Biosecurity Subprogram.
The pearl oyster (Pinctada maxima): a histological atlas of normal and diseased tissues
Pearl production accounts for more than half the value of the combined Australia aquaculture industries, yet little was understood of their health status prior to project no 94/79.
There is no text available which describes, the anatomy and histopathologically of the pearl oyster, Pinctada maxima , or the histopathological changes that occur with disease. This lack of published data is compounded by the fact that there are currently only 4 pathologists in Australia with significant experience and knowledge to interpret histology sections from pearl oysters.
The publication of the histopathology photographs collected during project no 94/79 plus other reference material collected by previous researchers will help to overcome this problem.
The ability to be able to recognise what is normal or abnormal is critical in the interpretation of histology sections and hence will affect the quality of diagnostic services that can be provided to the pearling industry.
The publication of this material will also act as a reference book for a range of other investigations into pearl oysters, such as, nutritional, husbandry and biology studies. It will ensure that the material gathered during project no 94/79 will be preserved for the future benefit of the pearling industry.
