In Australia, up to 90% of critical fish habitat for coastal fisheries, including seagrass, giant kelp, saltmarsh, and shellfish reefs, has been lost or significantly degraded. Many research studies have linked habitat with fisheries productivity, with habitat loss particularly impacting juvenile nurseries. Yet despite this information fish habitat restoration is not a recognised management tool in fisheries/harvest management strategies. Given this situation there is a strong need for a cohesive partnership across all fisheries sectors to support repairing productivity through fish habitat restoration and to create a forum where key sectors concerned for or dependent on aquatic habitat condition, can discuss problems and opportunities. This project will address a number of barriers limiting the restoration of fish habitat around Australia; accessibility of data relating fisheries production to habitat condition, limited penetration of this information into management and building a forum for the key fishing sectors to consider this information and develop responses.

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.
