Risk factors and management strategies associated with summer mortality in Australian abalone

In this project, we reviewed the scientific literature and collaborated with Australian abalone growers to develop a case definition for summer mortality. The case definition developed for summer mortality is as follows: i. Chronic mortality of unknown cause (if in doubt take this to mean...

Need

The Australian farmed Barramundi is estimated at over $37.1 million AUD with a production of over 3,772 tonnes annually (Savage, 2015). The value of the wild-catch sector was estimated to be $9.9 million AUD with 1,073 tonnes produced (Savage, 2015). These sectors of the industry as well as recreational and Indigenous fishers, are all at risk of being exposed to hazards potentially introduced by imported Barramundi and grouper products, which could pose significant consequences. The Australian Federal Department of Agriculture does not consider there is sufficient evidence to suggest that the import conditions for uncooked barramundi do not effectively manage the risk of pests and diseases of concern arriving in Australia. Until further evidence is generated to demonstrate that importation of uncooked barramundi products poses a risk that exceeds Australia's Appropriate Level of Protection, then regulatory actions to mitigate these perceived biosecurity risks are unlikely to be implemented. Risk mitigation requirements for importation of whole farmed barramundi include that the exporting country must, among other things, declare it has in place health surveillance and monitoring and that the fish were not derived from a population slaughtered as an official disease control measure. However, this self-declaration is not supported by rigorous testing to ensure compliance. There are current and have been no previous protocols in place to test for the target iridoviruses in imported barramundi and grouper product, so the efficacy of the existing import controls has not been subject to assessment at retail level. Sampling at retail outlets of uncooked whole and eviscerated barramundi and grouper commodities is proposed in order to better assess the efficacy of import conditions. This project will focus on determining the presence or absence of exotic virus genetic material in imported uncooked potential high risk barramundi and grouper commodity. Should any positive genetic material be detected confirmatory re-testing will be performed in order to reduce the risk of a false positive PCR test result and a subsequent project will be prepared o

Objectives

1. To determine the presence of Red sea bream iridovirus (RSIV), Infectious Spleen and Kidney Necrosis Virus (ISKNV), Scale drop syndrome virus (SDSV) and Singapore Grouper Iridovirus (SGIV) in high risk imported uncooked barramundi and grouper collected from seafood retail outlets throughout Australia, using PCR.
2. Review of imported uncooked barramundi and grouper commodity types and relevance to current import risk assessment and published literature.

Summary

Presently, the Australian Barramundi farming industry enjoys freedom from numerous internationally significant diseases including all from the Megalocytivirus genus of iridoviruses. These diseases are known to be causing severe impacts on farmed Barramundi and other species in southeast Asia and elsewhere. Australia’s biosecurity system is the primary barrier to keep such disease risks offshore. The importation of Barramundi and other finfish commodities for human consumption from countries where these diseases have been reported had not been fully assessed as a risk pathway for disease incursion prior to this project.

Investigate changes in acceptance of wild caught Barramundi in the foodservice and hospitality market sectors

In 2017 and 2018, wild-caught Barramundi fishers experienced large price fluctuations, with prices falling to an all-time low. Anecdotal information suggested that this was, in part, due to a lack of development in packaging, presentation and grading of products, which in turn had seen demand from...

The Detection of Ciguatera Toxins in NSW Spanish Mackerel

Ciguatera Poisoning (CP) is an illness through the consumption of fish containing naturally occurring toxins, and is considered a high risk for Australian seafood safety. Ciguatoxins (CTXs) are produced by benthic microalgae (Gambierdiscus spp). In Australia, CP cases are related to fish caught in...

Improving Southern Rock Lobster on-vessel handling practices, data collection and industry tools for lobster quality assessment

Need

The export of Southern Rock Lobster (SRL) from Southern Australia to international markets is one of Australia's most valuable fisheries. There are increasing trends in post-harvest mortality of SRL confirmed by the recent Fisheries Research and Development Corporation project (FRDC 2016-235). This is costing the industry millions due to stock losses, decreased consumer confidence in product quality and reputational damage to the SRL market brand. The causes of this increased post-harvest mortality are inconsistent across the industry sector with a range of factors implicated including environmental stressors, novel health conditions, and sub-optimal post-harvest practices. Results from (FRDC2016-235) indicate a need to optimise live lobster management processes across the entire post-harvest chain of custody in-order to minimize lobster mortality and enhance the economics of the SRL fishing and processing industry sectors.

The FRDC SRL live holding project (2016-235) conducted an analysis of the processing industry sector practices and provided guidance for best practices. These recommendations have been welcomed by the industry and further consultation has identified a critical need to extend this approach to the fishing component of the industry.

This project will address these key industry priorities and conduct an analysis of on-vessel live lobster handling and holding practices, quantify the impact of systems and practices on lobster quality and provide recommendations on improving on-vessel post-harvest practices. The current FRDC traceability project (FRDC 2016-177) is trialing a range of traceability technologies that this proposed new project will extend and enhance on-vessels to strengthen the capture, monitoring, and analysis of post-harvest data on lobster welfare, quality, and handling practices.

This project will also extend the development of practical and easy to use tools for the evaluation of lobster health including the handheld lactate meter and refractive index. Building evidenced-based approaches to measuring health and stress will provide all industry sectors with improved measurement of quality, animal welfare, and sustainability at all points in the supply chain.

Objectives

1. Investigate the impacts of on-vessel handling and maintenance practices on live SRL post-harvest performance
2. Develop practical tools for the improved management of SRL industry live lobster operations (ie hand-held lactate meter and refractive index including thresholds for poor lobster performance)
3. Extend findings to the SRL industry (best practice guides and workshops) and incorporation of results into the SRL Clean green program.

Risk analysis to identify and minimise biosecurity risks arising from recycling bivalve mollusc shell waste during shellfish reef restoration projects in Australia

The assessment indicated that heating recycled mollusc shells in water to 80°C for at least 5 minutes would meet the ALOP for all diseases (despite uncertainly for some disease agents due to lack of information, as indicated by ?), and was within the ALOP for all pests of concern. This method...
