Assessing the biosecurity risk of uncooked whole and eviscerated barramundi and grouper in relation to exotic viruses
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

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