Seafood supply chains are socio-ecological networks that are impacted by, and have implications for, fisheries and the marine environment. Increasingly, seafood supply chains are impacted by climate change (e.g., marine heatwaves), pandemics and market disruptions. Remaining resilient under disruption, while also being sustainable, is essential for continued seafood supply in a changing world. Understanding the behavioural responses of stakeholders to disruptions in the supply chain is crucial for the future planning of sustainable seafood supply. Knowledge of how and what type of information is generally shared across the supply chain, including during or after a disruptive event can be used to pin-point behavioural actions that lead to positive change. In seafood systems, how information sharing occurs beyond the producer stage of the supply chain is not well understood. We present results from a literature review and a stakeholder survey to identify the factors that influence information sharing across edible oyster and rock lobster supply chains in Australia. We outline how we are using this information to develop pathways for building resilience and sustainability under increasing disruption, and to increase the understanding of information sharing in seafood supply chains more broadly.
