The uptake of best practice approaches in fisheries and aquaculture is influenced by factors that inhibit or enable behaviour change, including psycho-sociological factors (i.e. how change or approaches are framed).
Previous FRDC research has indicated a need to identify how and where behavioural insights/interventions – which draw on psycho-sociological factors such as cognitive biases, social norms, and emotions – can be used to steer behaviour change towards preferred outcomes (e.g. stewardship, safety) in marine sectors. This project builds on current and emerging research on behaviour change in fisheries and aquaculture to consolidate a review of published literature and available grey literature and R&D (from academic and industry domains, including recent FRDC projects relating to behaviour change) that has identified psycho-sociological factors influencing behavioural change. The aim of this literature review is to identify the types of behavioural interventions that can (or potentially, cannot) achieve preferred outcomes for fishing and aquaculture sectors in Australia. Specifically, the review seeks to explore i) which kinds of behavioural interventions can be effective in achieving positive change, ii) where (and just as importantly, where not) these interventions may be applied in fisheries and aquaculture sectors, iii) identify (potential) limitations of interventions, and to iii) bring these findings together to inform and underpin development of two relevant and engaging training webinars and associated resource materials, and iv) make recommendations for further focused trials/intervention research which could be undertaken to further support and expedite desired outcomes in Australian fisheries and aquaculture.

There is rapidly growing interest in the development, application and evaluation of behavioural interventions and they show great potential, however, they are also complex to design, test, and implement. Individuals are more likely to change their behaviours if they have the necessary skills and perceive they can do so (capability), if their environment (physical as well as social) provides an opportunity to do so (opportunity), and if they are motivated to achieve a particular endpoint through this behaviour (motivation), either through conscious decision-making or automatic processes, such as momentary cues. Further, the use of behavioural interventions has not been without critique, with concerns about ethics, manipulation, or risk to human agency. There are also concerns about the effectiveness of behavioural interventions, which may derive from several reasons: for example, due to misunderstanding the behaviour that is intended to be changed and the expected response by the audience. A behavioural intervention will be ineffective if the messaging or delivery causes confusion or if it only has a short-term effect. Some interventions can cause unintended consequences or compensating behaviours resulting in no net effect. These reasons highlight the importance of appropriate contextual understanding and well-defined outcomes for the design of effective behavioural interventions.

There are also different avenues for intervention beyond cognitive biases: education, persuasion, incentivisation, coercion, training, restriction, environmental restructuring, modelling and enablement, and the framing and implementation of these can differ depending on who the intervention is targeted at and under what context. Targeting behaviours in fisheries and aquaculture may enhance engagement and sustainable changes in the longer term (e.g. via development of new social norms), but to achieve this, changes in the determinants of behaviour are required. Actions (e.g. citizen science projects, local management practices), feelings, values (e.g. connectedness to oceans, the realisation of links between ocean health and human health) and social norms are embedded in and influenced by, local environments and social spheres that can transcend geographical boundaries. Our project will explore these nuances and convey concise summaries of behaviour change interventions for end-users via webinars, fact sheets, a simple decision tree tool (described below) and several short videos. The project intentionally has a broad focus (across fisheries and aquaculture sectors) in its review and outputs, as it is designed to equip potential developers and implementers of behavioural interventions with the skills and knowledge to do so in their own unique context. However, we will engage with industry partners (including FRDC extension officers and the industry advisory groups) to specifically ensure that the knowledge and tools produced (i.e. extension products) will be accessible and adaptable to the diversity of relevant contexts across these sectors - and useful for end-users seeking to motivate behaviour change whilst still retaining industry trust and engagement.

The project brings together necessary interdisciplinary research expertise (details outlined below) in the fields of behavioural economics, resource and fisheries economics, socio-ecology, fisheries ecology, science communication and cognitive psychology. In addition, the transdisciplinary potential of this project will be achieved via collaboration with a research advisory panel (to ensure rigorous research outcomes) and an industry level advisory panel (to ensure that the results and suggested interventions/activities are fit-for-purpose and accessible to the sector). Working with these panels (which would ideally include FRDC partners), we will ensure that the research is co-designed – and thus, project outputs are fit-for-purpose/context. Our team’s existing collective research on adoption and uptake of interventions clearly shows that engaging and involving end-user at creation stages increases uptake of results – hence, the value of our industry advisory panel. In addition, by engaging with industry leaders, we will create industry champions for the project who may assist with the dissemination of outputs. Together, the advisory groups will help to further define/adapt the scope of the project to achieve impact.

Overall, these collaborations and contributions will ensure that this project will deliver a comprehensive and industry-relevant overview of current understanding of behaviour change interventions, that addresses end-users’ identified needs, and that inspires community trust, in formats that are palatable and accessible to them and the fisheries and aquaculture sectors more broadly..

‘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.

WAFIC and DPIRD are seeking an improved understanding of the methods available for valuing fishery access rights, their relative advantages and disadvantages, and more specifically which methods would be most relevant and appropriate for Western Australia’s small-scale fisheries. This is to better ensure that future compensation schemes better meet their objectives while also building increased certainty and confidence for industry and the holders of access rights, which ultimately supports improved resource security.

Our proposed approach draws on relevant literature and consultation with both government and fishery stakeholders (including fishers, investors, and brokers) to understand the range of approaches applied to valuing commercial fishing rights and their relative advantages and disadvantages. We will then define some key evaluation criteria that define what an appropriate compensation method is and then assess identified methods against these criteria. This evaluation will also consider how the applicability of methods may vary for different fishery types and circumstances.

The end outcome will be identification of the most appropriate valuation methods for the development of future compensation schemes for different fishery types, with a particular focus on small-scale fisheries. This advice will be developed to be readily adopted and applied by in relevant legislation and/or policy instruments.
