AAHBS provides a cohesive national approach to FRDC-supported aquatic animal health R&D in Australia by providing leadership, direction and focus for health R&D and other related non-R&D activities. AAHS was renewed in 2012 based on national need, previous performance and strong stakeholder support. Key strengths include its strategic focus and the establishment of a network of aquatic animal health experts and research providers. An external review of AAHS was undertaken in 2015 and it found that the consensus among the major stakeholders was that AAHS provides an essential service for the major stakeholders. Thus, continuation of AAHS beyond 2016 on the basis of a shared financial commitment by stakeholders from industry and governments is highly desirable.

Australia’s aquatic animal sector is free from many diseases that occur overseas, providing us with a competitive advantage in both production and trade. While the number of aquatic animal species and the absolute number of aquatic animals being farmed in Australia is increasing annually, new diseases caused by emerging infectious agents (e.g. new yellow head virus genotypes, oyster oedema disease, ostreid herpesvirus, Bonamia exitiosa) continue to threaten the sustainability of significant enterprises, and the call on health services to support this expanding industry is growing.

In addition to aquaculture, aquatic animal health R&D is required for the other aquatic animal sectors, including wild-capture (c.f. Edwardsiella ictaluri in catfish), recreational (c.f. Perkinsus in oysters) and ornamental (c.f. gourami iridovirus), that share the aquatic environment. Thus health services need to be coordinated across all aquatic sectors to ensure synergy while avoiding duplication. FRDC, through AAHBS, plays a major role in addressing research needs and training in aquatic animal health. With its incumbent expertise and experience, AAHBS is able to direct these activities in the most pressing areas.

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.

Australian prawn production at around 22 kilotonnes is valued in excess of $250 million. Clearly, the prawn fishery is an important natural resource for Australia that is also the basis for a significant export industry. In addition, prawn aquaculture is a significant industry in northern Australia and accounts for around 14% of the total volume of Australian prawn production. Infectious myonecrosis is a viral disease that has caused significant disease outbreaks and mortalities in farmed Penaeus vannamei in Brazil and South-East Asia, including Indonesia. While P. vannamei is considered the principal host, experimental infection of P. stylirostris (Pacific blue shrimp) and P. monodon (black tiger shrimp) has been reported. The susceptibility of other shrimp/prawn species is unknown. Information on the susceptibility of prawn species important to Australia, including banana prawns (Fenneropenaeus merguiensis), brown tiger prawns (P. esculentus) is lacking. This project would provide information on the susceptibility of two important species of Australian prawns to exotic IMNV. Such information is important to policy-makers, regulators and primary producers with respect to relevant biosecurity issues at all levels of government.
