Coastal lagoon systems in Tasmania form a fundamental part of coastal ecosystems. Healthy lagoons support local biodiversity, and play a key role in nutrient cycling and flood protection. They provide opportunities for sustainable aquaculture, fishing and tourism, while also being appreciated for their recreational amenity and cultural values. Sustainable management of coastal lagoons is essential to environmental and socioeconomic development.

There is limited information about the ecosystem drivers that are influencing the changes being observed in Pipe Clay Lagoon, leading to knowledge gaps in decision making tools and monitoring strategies required to identify and mitigate these changes. The proposed application is a multifaceted approach to investigate the environmental drivers of change in Pipe Clay Lagoon. The findings can then be used to provide valuable guidance for the management and conservation of other coastal lagoons in Tasmania facing similar challenges, providing a model for proactive monitoring and ongoing sustainability.

The FRDC has a responsibility to ensure that research is undertaken to assist in the management of fisheries and aquaculture resources for ongoing sustainability. The changes being experienced in Pipe Clay Lagoon will have implications on the availability and suitability of the lagoon as a sustainable aquaculture site. The planned approach and objectives of the application align with the FRDC’s R&D Plan for 2020-2025 through:

- Building people's capacity and capability
- Ensuring that resulting knowledge and innovation is adopted for impact through awareness of the needs of the ‘adopter’, local context and effective networking
- Continual improvement and collaboration of industry and community to deliver competitive advantage, healthier ecosystems and community support
- Provision of foundational information

Equally and importantly the application aligns with the NRM Strategy for Southern Tasmania 2030 for Pipe Clay Lagoon and similar systems in that wetland health is improved for socio-economically important systems by working with key partners and encouraging investment in monitoring, land and water management practices and on-ground works.
The enthusiasm of those engaged in the stakeholder consultation process was a strong indication of the need, interest and urgency of the application.

Fish are totemic and a primary food source; and so are part of the deep cultural, spiritual and economic connections Aboriginal communities have to their waterways that are part of ‘Country’. Cultural knowledge tells us that when there’s more water availability cultural fishers experience increased total catches and greater diversity of target species, and they fish more (e.g. increase in recreational and subsistence fishing). These narratives also suggest that as a result of these improved cultural fishing opportunities, there are flow on socio-economic benefits to household budgets, diets of communities, social behaviours and mental health and well-being.

Water is sacred and living; and central to the cultural, social and spiritual identity of Aboriginal people, as well as to their livelihoods. Conceptual models underpinning western water management frameworks and decision making do not incorporate Aboriginal/First Nations socio-cultural complexity, local knowledge and governance arrangements. These are critical – Aboriginal/First Nations people have strong connections with fish, water, rivers and knowledge to contribute to planning, as well as a fundamental right to participate. Water and fish are central to the way of life, two-way knowledge and planning frameworks will support reciprocity in engagement and participation.

Two-Eyed Seeing Frameworks (Ganma, Yolgnu for two-ways) provide a way forward for cultural fishery assessments supporting equitable and sustainable access to shared resources. In this framework, knowledge systems (western and cultural) contribute in parallel, on an equal footing, and both serve as evidence bases to produce an enriched picture of mutual understanding. Application of this framework can empower Aboriginal communities to participate more equitably and negotiate by using their science and values and providing a method for inclusion.

The overall objective of this proposed project is to empower Aboriginal communities through application of a “Two-Eyed seeing framework” (Reid et al. 2020) to participate more equitably and negotiate for cultural fishing practices and water allocation and management. This project will define the cultural fishery and quantify the socio-economic value of cultural fishing in two NSW river regions, and assist communities to identify water management needs for key cultural fish species to support ongoing planning and negotiations. It will improve our current fishery and water management by providing a pathway for cultural fisheries and cultural science to be included. Overall, it will increase our current knowledge of fish and fisheries, by bridging the gap between cultural science and western science practitioners and knowledge holders to share understandings, insights and skills. The application and extension of this framework to a national project will be considered for future use in addressing cultural fishery allocations and management.
