Australian working age adults with social and economic disadvantage have significantly poorer oral health outcomes than those from advantaged backgrounds. This project explores how changes in social position over time, and interactions between different forms of social disadvantage, contribute to social inequalities in oral health. This project expects to improve understanding of social inequalities in oral health, and its solutions, by developing and applying analytical and simulation models. This will help identify ways to reduce the persistent social inequalities in oral health outcomes in working age adults. In doing this, it will inform policies in future that will significantly improve the well-being of Australian working age adults.Read moreRead less
Social practices of oral health in Australian preschool children. The aim of the study is to explore "social practices" of oral health in Australian (Aboriginal and non-Aboriginal) preschool children. We use this emerging theory to move away from focusing on individuals and individual behaviour (and blame) to identify and map social practices: actions, materials and meanings families attribute to

The aim of the study is to explore "social practices" of oral health in Australian (Aboriginal and non-Aboriginal) preschool children. We use this emerging theory to move away from focusing on individuals and individual behaviour (and blame) to identify and map social practices: actions, materials and meanings families attribute to
child’s oral health. Expected project outcomes include identifying practices promoting or undermining children’s oral health that can inform upstream and downstream policy directions and practices to improve health outcomes. This offers a new approach to "wicked" problems such as oral health where extensive
effort has not reduced morbidity and cost despite rhetoric that oral health is preventable.Read moreRead less

Summary
‘Overcatch’ or ‘fouling’, whereby juvenile oysters (wild spat) or other aquatic organisms attach themselves to semi-mature oysters, is the largest farming challenge for Sydney rock oyster (SRO; Saccostrea glomerata) growers in Australia and represents a major barrier to efficient and sustainable production (Wayne Hutchinson, FRDC, personal comm.; Durr & Watson, 2010).

Without timely intervention, fouling often renders the oysters unmarketable, leading to substantial proportions of product being discarded or having growth rates considerably slowed (Watson et al. 2009; Adams et al. 2011). It is estimated that 30–50% of SRO grown in Qld and northern NSW are wasted as a result of fouling with a potential value of $13–30 million/annum (Tim Prowse, QOGA, personal comm.; FRDC, 2022); this is either because the products become unsellable or due to losses associated with current overcatch control treatments. The inability to effectively manage overcatch has contributed considerably to the decline of Qld’s oyster industry over the last century, and similarly remains a significant financial impost to NSW oyster growing operations (de Nys et al. 2002; Cox et al. 2012).
At present, oyster growers typically attempt to mitigate the impacts of overcatch using methods like air drying and heat immersion; but both are labour intensive, have no clear guidelines or benchmarked specifications to support new growers in their implementation, and can result in significant mortalities or even total crop losses if undertaken incorrectly (Fitridge et al. 2012; 2014; Mayrand et al. 2015). While two relatively new technologies exist that hold promise for successfully managing overcatch, namely the ‘cold shock’ hypersaline system and FlipFarm system (Cox et al. 2012; Jackson, 2021), these have not yet been widely trialled or adopted in Australian oyster growing regions. There is thus a pressing need to better understand the optimal parameters for effectively eliminating overcatch while retaining host oyster health in commercial production settings.
The proposed project will respond to this longstanding need by evaluating and comparing the efficacy, practicality and cost-effectiveness of these various existing and emerging overcatch control methodologies under the same commercial environment, location and stock. Trials of these four treatments (air drying, heat immersion, cold shock system, FlipFarm system) will be carried out at established oyster leases in Qld’s Moreton Bay region, which is particularly prone to the impacts of fouling and therefore offers the ideal location to determine the efficacies of different methods in controlling overcatch in on-farm settings. The location also has no pre-existing incidences of QX disease that is currently decimating many other SRO growing regions in NSW and Southern QLD. The findings from this work will provide essential outputs, including validated methods and Best Management Practices (BMPs), which will be widely disseminated to the national oyster industry through various relevant forums.
With the Qld government in particular seeking to rejuvenate its oyster industry (McDougall, 2020), and the entire Australian oyster industry looking to expand and boost production (Oysters Australia, 2020), the timing of this project is optimal. The results will not only assist new growers entering the industry, but they will also provide essential learning to established growers throughout Australia who experience significant oyster losses and labour costs associated with overcatch management. The project also aligns with the Oysters Australia Strategic Plan 2020–2025 to (i) increase the sustainable, efficient production of oysters and their management on farm; (ii) manage industry risks; and (iii) increase industry knowledge, skills and networks. It will further help to meet the objectives of the FRDC’s R&D Plan 2020–2025, particularly Outcome 1 (i.e., ‘growth for enduring prosperity’), by providing the oyster industry with genuine opportunities to reduce crop losses, increase profitability, expand production and enhance their reputation in a stewardship context. From a broader societal perspective, the project outcomes will be crucial in building a properly functioning circular economy in the oyster industry, by preventing the creation of waste in the first place. Objectives: 1. To improve knowledge and establish critical information for controlling overcatch on SRO using existing air drying and heat immersion methods in commercial production settings. 2. To provide oysters growers with validated new technologies (cold shock system, FlipFarm system, temperature / RH sensors) that offer more effective and efficient control of overcatch on SRO in commercial production settings. 3. To reduce oyster losses/deaths, as well as labour requirements, associated with controlling overcatch on SRO, when compared to current practices. 4. To develop Best Management Practices for overcatch control that can be used for demonstration and training to the wider oyster-growing community and public. Read moreRead less

The program will be developed in a way that supports an evidence-based approach to developing and trialling sustainable alternative commercial fishing gears, and be run in collaboration with relevant Government agencies and fisheries stakeholders.
Through the additional support of co-investment of $4.5 million by FRDC (in line with this application and the approved funds listed under project 2023-154), the program will be delivered in two stages across a six-year timeframe (up to a total investment of $9 million).
The fishing methods to be trialled as part of the first stage will range from exploring enhancements of existing low-impact gear types, through to trials of innovative harvest technologies. The alternative low-impact harvest technologies will first be trialled in order to demonstrate their triple bottom line credentials. After this, the second stage will support broader implementation and evaluation of commercial application over a three-year period.
The program of works will also explore additional opportunities to enhance the economic value and social profile of the fishery, to ensure that any new harvest technologies align with global best practice standards, product value adding to enhance profitability margins, and improvements in social acceptability.
Wild caught seafood also allows for a diverse mix of species that appeal to a range of consumers and seafood businesses. It is planned that this work will explore potential opportunities for market expansion. Objectives: 1. Undertake gear trials with clear monitoring and assessment of gear performance against economic, ecological (including SOCI interactions) and social indicators. 2. Evaluate different gear trial pathways to understand the cost benefit trade-offs, timeframes and identify principles for success 3. Identify attitudinal, behavioural, and contextual factors affecting the adoption and perception of the alternative gear, and design and implement interventions to alleviate this. 4. Support developmental fishery implementation and optimisation of gears and business models to ensure long-term sustainability. 5. Understand the market and consumer preferences associated with caught combination of new gears and undertake optimisation of post-harvest processes and business models to support profitability. 6. Develop forums and communication materials to support responsible innovation and knowledge transfer for and across Australian community, and with a focus on commercial fisheries and key rightsholders and stakeholders Read moreRead less

Even fewer mechanisms exist that attempt to synthesise research from across the marine science space specifically, wherein which the Fisheries RDC (FRDC) operates.
The aim of this project is to input FRDC research into the RLA platform, thereby making it more discoverable, accessible, and usable. The RLA service offers various knowledge tools, which intend to be explored as part of this project also, to allow the FRDC to explore and better understand the marine science and agricultural innovation landscape. Furthermore, the project aims to make the RLA platform known within the wider marine science community and across different RDCs and encourage the adoption of the new capability to link industry and research.
This project expects to yield several benefits for actors both within and outside the fishing and aquaculture community. The RLA platform acts as a link between government, business, and research sectors. Inputting FRDC research into the RLA platform encourages collaboration and innovation between actors both within and outside the marine science space and facilitates knowledge transfer between these currently disconnected actors.
Objectives: 1. To share Fisheries Research and Development Corporation research project data to be made available on the Research Link Australia platform, thereby making it more discoverable, accessible, and usable. 2. To explore different knowledge tools (i.e., Research Link Australia-generated dashboards or applications of Large Language Models) to better understand the marine science space and explore the agricultural innovation landscape. 3. To make the Research Link Australia platform known within the wider marine science community and across different Research and Development Corporations and encourage the adoption of the tool.
