Improving early detection surveillance and emergency disease response to Pacific Oyster Mortality Syndrome (POMS) using a hydrodynamic model for dispersion 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...

Summary

Infection by marine Vlbrlo bacteria is still considered to be
the major opportunistic cause of mass mortalities of pearl
oysters (Pinctada maxima} on farm lease sites in the north
west of Western Australia. Vibriosis of P. maxima was found
to occur following some form of stressful husbandry practice
as similar mortality outbreaks were never apparent in natural
populations of pearl oysters throughout this investigation.
Potentially harmful Vlbrlo species were found to be associated
with pearl oysters in the Broome region throughout the year;
therefore vibriosis could occur at any time to oysters
subjected to excessive stress.

Aquafin CRC - Atlantic Salmon Aquaculture Subprogram: model development for epidemiology of Amoebic Gill Disease

Amoebic Gill Disease (AGD) is the main health problem affecting salmon industry in Southern Tasmania. To improve management of fish with AGD on the farms, the industry needs better understanding of AGD epidemiology. This will provide a basis on which to develop strategies for new...

APFA IPA: RNAi treatment of broodstock to reduce disease impacts in farmed prawns

Reported here are the outcomes of a project with original objectives to assess (i) the ability of injected double-stranded (ds)RNA antivirals to reduce Gill-associated virus (GAV) infection loads in Black Tiger prawn (Penaeus monodon) broodstock and whether this can (ii) reduce GAV infection...

After QX impacted oyster production in 2004, Broken Bay Oyster Association (BBOA) and encouraged by Government at all levels invested in new growing techniques with triploid pacific oysters. NSW DPI forecast 466 bags production by 09/10. by 10/11, BBOA produced 4569 bags - 10 times forecast and was the leading employer in the community and had resulted in an environmental cleanup of 8000 tonnes of rubbish removed. BBOA is today recognised and acknowledged nationally and internationally as an iconic example of a phoenix industry – emerging from the ashes of disaster. Members became active internationally to understand the disease and possible ways of managing oyster farming in the face of this new threats and invested (in-kind and $$) in world leading research to develop management plans around disease.

Despite significant pro-active undertakings by BBOA & government, on 22/01/2013, POMS was confirmed in a major juvenile growing area in the HR. By 8/02/2013, POMS has been identified throughout the Hawkesbury, Patonga and Brisbane Waters estuaries. Oyster losses are extreme (99% death of juvenile oysters) and still unfolding. The disease speed of infection and level of devastation was unprecedented. Oyster businesses got minimal notice to handle or sell stock before it became un-saleable.

To move forward, BBOA recognises the need to work with stakeholders (researchers, administrators and other river citizens) to identify possible survival mechanisms for the oyster industry in the Hawkesbury. IMPORTANTLY, the combination of QX and POMS offers a unique opportunity for production solutions to be identified, analysed and costed as a planning tool for other as yet unaffected oyster production areas around Australia. The devastating speed of the disease has resulted in the total removal of cash flow from BBOA and limited their opportunity to respond with alternate production methods.

Objectives

1. Review current production and culture methods and possible alternatives as they relate to mitigating POMS.
2. Determine feasibility of alternative options through benefit cost analysis.
3. Review current administrative and regulatory barriers to change and methods to overcome them.

Aquatic Animal Health Subprogram: Identifying the cause of Oyster Oedema Disease (OOD) in pearl oysters (Pinctada maxima), and developing diagnostic tests for OOD

The goal of this project was to investigate the cause of oyster oedema disease (OOD) in Australian pearl oysters so that diagnostic tests and management practices for the disease can be developed. OOD has been associated with mortalities in some pearl oyster farming areas. However, the cause of...
