Due to the recent detection of POMS in wild Pacific Oysters in the Port River, the SA industry urgently need POMS resistant oysters. Having POMS resistant oysters stocked onto farms prior to any potential outbreak will be critical for protecting the industry from significant losses and financial impacts.
To achieve a resistance level of over 90% for ≥ one year old oysters, the SA Pacific Oyster selective breeding program will need to establish at least three more generations of families for genetic improvement after the completion of the Future Oysters CRC-P project in 2019.
Establishing the SA Pacific Oyster selective breeding program requires specific techniques and skills. SARDI is the only organisation in SA that has the purpose-built hatchery facility for this species and has produced target numbers of Pacific Oyster families over the last three seasons. SARDI also has a well-established team in oyster genetics and bivalve hatchery technologies.
To support the Stage 2 development of the SA selective breeding program, Flinders Ports, in partnership with the Fisheries Research and Development Corporation (FRDC), ASI, SAOGA and PIRSA-SARDI will jointly fund this project for the SA oyster industry to address POMS risks, and further mitigate the risk factors associated with the spread of POMS outside the Port River related to dredging activities in the Outer Harbour.
1. Develop selective families with 90% POMS disease resistance for ≥ one year old Pacific Oysters
2. Support the SA industry by provision of high POMS resistant broodstock for commercial spat production

A total of 221 new selectively bred families were produced at the South Australian Research and Development Institute (SARDI), West Beach, between 2019 and 2023, meeting project objectives. The 2019-year class was challenge tested in the Port River, SA for POMS resistance, after which the imported Tasmanian broodstock were incorporated into the program and the objective changed to improve both POMS resistance and POSS in SA. Details of the POSS field challenge tests and results will be available in the final report of FRDC project 2020-064. In the 2022 families, the last year class produced at SARDI, the average EBV of the top five POMS resistant families was 100% and the average EBV of the top five POSS families was 90%.

SPECIES
Pacific Oyster Mortality Syndrome (POMS) is a disease caused by Ostreid Herpesvirus type 1 (OsHV-1) microvariant, which causes rapid high mortalities (up to 100%) in Pacific oysters. POMS has caused significant economic impacts to the oyster growing industry in parts of NSW and Tasmania where it occurs. On 28 February 2018 OsHV-1 was first detected in Port Adelaide River feral oyster populations. PIRSA and industry mounted an immediate emergency response aimed at containing the virus to the Port and preventing spread to the nearby oyster industry (>25km away).
In the absence of accurate information, surveillance designs and emergency response plans (including translocation protocols) assume a disease spread distance of 5NM (10km) to define epidemiological units for all water bodies (see Figure 1). That uncertainty causes policy makers to take a conservative approach. Consequently there is a need to improve the accuracy of predictive information used to manage such aquatic disease incursions.
Aim: Model the dispersal of Ostreid herpesvirus (OsHV-1) particles from various locations around South Australia to determine epidemiological units aimed at improving surveillance, biosecurity zoning and future emergency responses.
This project aligns with two key objectives of Australia’s National Strategic Plan for Aquatic Animal Health (AQUAPLAN 2014-2019): (1) Enhance surveillance, and (2) Strengthen emergency disease preparedness and response capability. See http://www.agriculture.gov.au/animal/aquatic/aquaplan.
A recent FRDC project (2006/005) demonstrated how various oceanographic data can be incorporated into a hydrodynamic model (e-SA marine system) to map past, present and future ocean conditions. This project proposal will provide a case study for how such a model can predict pathogen spread to underpin improved surveillance designs, effective emergency disease response and appropriate biosecurity zoning for translocation protocols.
1. To model viral particle dispersal at key locations around the State, including commercial oyster growing areas, known feral oyster populations and ports, and incorporating seasonal oceanographic parameters
2. Using hydrodynamic model outputs, identify epidemiological units to inform surveillance, disease management and emergency disease response activities
3. Demonstrate how hydrodynamic model outputs of predicted viral particle dispersal can be used to develop a risk-based surveillance design for the detection of OsHV-1

Rapid predictive capability of viral spread through water during an aquatic disease outbreak is an epidemiologist’s dream, and up until now has not been achievable. A biophysical particle tracking model for Ostreid herpesvirus 1 microvariant (OsHV-1) that causes POMS was developed to determine virus spread during disease outbreaks in South Australian coastal waters. Model outputs from 23 hypothetical outbreaks across the State have provided valuable information for PIRSA to review and update current Disease Management Areas (DMAs) for POMS. Outputs from this project will greatly enhance future disease surveillance programs and emergency responses.

The establishment of a new native oyster and/or western rock oyster aquaculture sectors in SA and the former in Tasmania will not only diversify the business risk of the existing Pacific oyster sector, but has the potential to become a multi-million dollar industry itself. As native oysters would be more suited to subtidal or low intertidal culture while western rock oysters are an ideal alternative species to mitigate POMS, the successful development of these aquaculture sectors will strengthen the confidence of existing/new growers and investors in Pacific, western rock and native oysters; thereby encouraging further expansion of the industry. In addition, supporting species diversification is one of the high strategic priorities in the Oysters Australia Strategic Plan 2014-2019.
1. To develop Native Oyster on-farm growing methods that maximise survival and growth in South Australia and Tasmania
2. To compare the performance between Pacific Oysters and Native Oysters in South Australia
3. To establish a Native Oyster farmers network to share new techniques and knowledge
4. To develop translocation protocols for the safe translocation of Western Rock Oysters to South Australia
5. Trial Western Rock Oysters in the field in South Australia to assess their performance and viability of a potential industry if agreed by industry and regulators

Pacific Oyster Mortality Syndrome (POMS), the disease caused by OsHV-1 microvariant, results in high and rapid mortality in Pacific Oysters (Crassostrea gigas) and has been responsible for significant economic loss to oyster industries in Australia and around the world. The diversification of commercial production into different oyster species (Native Oysters and Rock Oysters), that are not susceptible to POMS, has been proposed as a way to mitigate the risk of POMS in southern Australia. However, the Australia Native Oyster (Ostrea angasi) industry is still in its infancy, with knowledge gaps along the production chain. Additionally, there are no wild populations of Rock Oysters (Saccostrea sp.) in South Australia. Despite Rock Oyster aquaculture being well established in New South Wales and recently in Western Australia they have never been commercially produced in South er Australia and translocation policies to move them around the state are non-existent. This project aimed to improve on-farm production of Native Oysters and determine if Rock Oysters can be safely translocated to South Australia from Western Australia, to help Australian oyster growers to diversify into these species.

During the last two decades a number of disease outbreaks have led to mass oyster mortalities and the closure of several oyster-harvesting regions, resulting in multi-million dollar losses. These outbreaks mirror a global pattern of increased aquaculture disease, with disease emergence potentially linked to environmental degradation (pollution) and climate change related processes, such as rising seawater temperature. Within NSW estuaries, multiple microbiological agents have been implicated in oyster diseases, but a clear understanding of the ecological and environmental drivers of disease outbreaks has remained elusive. This means we cannot predict when outbreaks will occur, making it very difficult to manage infection events and develop strategies to mitigate future oyster disease events.
Since 2008, Pacific Oyster fisheries in several parts of the world have been decimated by the influence of Pacific Oyster Mortality Syndrome (POMS), resulting in high (>95%) rates of juvenile oyster mortality. Recent evidence indicates that POMS is a polymicrobial syndrome, that is not only caused by the OsHV-1 virus, but includes the involvement of pathogenic bacteria from the Vibrio genus, a bacterial group comprising species that cause disease in a diverse range of marine animals and which is responsible for significant mortality in a variety of aquaculture industries. However, our understanding of this complex interaction is limited.
This project will provide valuable insights into the microbial communities associated with oysters, how those communities vary and how they might influence the course of other diseases. The project will also indicate whether breeding influences the microbial communities associated with oysters and whether this is influencing the impact diseases like OsHV is having on different Pacific oyster families.
1. Define microbial communities associated with oysters and identify threats
2. Link changes in environmental conditions to changing microbial communities
3. Better understand the association between microbial communities and disease

The principal goal of this research was to provide a detailed characterisation of the oyster microbiome and identify links between specific features of the microbiome and oyster disease and mortality events. The conceptual framework for this work is based upon: (i) increasing evidence, across a broad range of species, that the nature of a host organism’s microbiome exerts a fundamental control on host physiology and health, and (ii) the critical paucity in knowledge on the factors contributing to oyster health and the triggers for oyster mortality events and disease outbreaks. The research reported here involved a collaboration between the University of Technology Sydney (UTS) and the NSW Department of Primary Industries (DPI), whereby the UTS members of the team provided expertise in molecular microbial ecology and the DPI team members provided expertise and support in oyster physiology and ecology and aquaculture. The research involved a large-scale screening of the microbiomes of both Pacific Oysters and Sydney Rock Oysters using high-throughput DNA sequencing technologies, providing a characterisation of the microbial communities associated with oysters. The outcomes of this analysis revealed that for both Pacific Oysters and Sydney Rock Oysters, the oyster microbiome is remarkably variable among different oyster families, and over space and time, indicating that both intrinsic physiological features of the oyster host and environmental factors play a role in governing the oyster microbiome. Notably, despite this heterogeneity, a small sub-set of the microbiome was shown to be conserved across oysters within a species, pointing to the existence of a core group of microbes with intrinsic links to oyster ecology and condition. Similarly, a small group of microbes, including members of the Vibrio genus, were consistently associated with diseased or susceptible oysters, indicating a potentially antagonistic role of these microbes. These observations support the hypothesis that the oyster microbiome plays a role in defining oyster health, but also reveal substantial complexities related to the marked heterogeneity of the oyster microbiome over space and time. Appropriately considering this microbiome heterogeneity, while also sharpening focus on the few core microbiome members identified in this research, will be important requisites for
future efforts hoping to employ the oyster microbiome for diagnostic purposes.
