PIRSA Innovative Solutions: Investigations to address key policy gaps associated with the development of clam farming in South Australia: genetic and health issues aligned to translocation and stock identification

Need

The need for the development of an Australian clam aquaculture industry is a direct outcome of the inability of the wild clam industry to meet the demand of a large international market prepared to pay a premium price for quality Australian clams. While clam aquaculture has been successfully developed on a large scale overseas, none exists in Australia at this time. Currently, a feasibility study to evaluate clams culture on intertidal and subtidal leases in SA is underway with the funding support from FRDC, SA Clam Aquaculture and SARDI (FRDC project 2009/208).

At the same time, PIRSA Fisheries and Aquaculture is evaluating policies related to clam aquaculture development in SA to ensure the long term viability of both the wild harvest fishery and the successful development of a sustainable aquaculture industry. The critical knowledge gaps identified for this assessment are: 1. population genetic structure of clam species in South Australia; 2. potential genetic and biosecurity risks of moving farming stocks between localities, and 3. effective and efficient methods to distinguish hatchery produced stock from wild stocks. Understanding the population structure of this clam species and biosecurity risks of moving stocks will allow for the development of far more specific management strategies to control the potential adverse genetic and biosecurity impacts of farmed clams on the local wild population, thus protecting its genetic integrity if genetically divergent localised populations exist along the SA coastline. Practical identification of hatchery stocks will ensure compliance with wild fishery, aquaculture and recreational harvesting policies. All these need to be taken into account in developing clam aquaculture in SA.

Objectives

1. To characterise the genetic population structure of clams, Donax deltoides or Katelysia rhytiphora (to be determined) in South Australia
2. To identify and evaluate method(s) for differentiation between farmed and wild clams
3. To identify potential biosecurity issues relating to commercial clam aquaculture
4. To identify practical ways to mitigate unaddressed risks associated with clam aquaculture development in SA

Aquatic Animal Health Subprogram: Exercise Sea Fox: testing aquatic animal disease emergency response capabilities within aquaculture

Project number: 2012-044
Project Status:
Completed
Budget expenditure: $51,847.02

Need

Exercise Sea Fox is scheduled to commence 23 October 2012, initially as a pre-planned State focussed aquatic disease outbreak exercise. The objective of requesting funding from FRDC is to elevate the exercise to a national focus.

Emergency response arrangements and exercising these arrangements for an aquatic disease outbreak is at the core of disease prevention and management. Aquatic diseases that are of high priority and threaten the sustainability of Australian aquaculture industries include: Pacific Oyster Mortality Syndrome (POMS) and Abalone Viral ganglioneuritis (AVG). POMS is a high priority disease particularly for SA, NSW and TAS.

Government and industry have state and national obligations for responding to biosecurity incursions. The emergency response framework includes OIE manuals, AQUAVETPLAN manuals, State legislation and emergency management plans. Readiness requires on-going training and exercises to maintain preparedness for an incursion. The need for an aquatic disease exercise has been highlighted at both State and National levels.

Aquaculture industry awareness and training has previously been identified as a gap in biosecurity emergency response preparedness. It has also been recognised that other sectors within government are not familiar with the obligations and needs of an aquatic animal emergency disease response.

Exercise Sea Fox will include national (SA, NSW and Tas) participation from both government (including DAFF) and industry bodies. The exercise will test State and national arrangements. Although this exercise will be based within SA, State emergency response frameworks are based on international and national guidelines.

Both government and industry are on a heightened state of alert where early detection and rapid emergency response is vital for effective control and containment of significant disease outbreaks.

Objectives

1. Raise awareness within government and industry of national and state emergency management obligations.
2. Provide government and industry personnel with an opportunity to develop and practice skills and procedures when responding to an emergency aquatic animal disease
3. Develop knowledge within government of the aquatic industry
4. Identify gaps in national, State and industry’s aquatic response frameworks

Development of a national biotoxin strategy

In Australia aquaculture and wild harvest of shellfish is an economically important and growing industry. The safety of these products as a food source is of utmost importance from both public health and economic points of view. One of the potential problems faced by shellfish growers is...

Innovative Solutions for Aquaculture: potential for parasite interactions between wild and farmed kingfish, discrimination of farmed and wild fish and assessment of migratory behaviour

This project greatly contributed to an increased understanding of parasite fauna of yellowtail kingfish in Australian waters. This baseline information is critical to understanding potential parasite interactions between wild and farmed kingfish. Our risk assessment enables consideration...

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...
