Title: International nutrient flows from fisheries trade in Pacific food systems Abstract: Aquatic food trade distributes essential nutrients from fisheries across the globe. Yet these nutrients often flow toward more secure nations, even though many fisheries are supplied by lower-income, nutrient-insecure states. These trade networks are vulnerable to environmental and socioeconomic disruptions, which can reduce fisheries production or increase reliance on imports, with disproportionate impacts on already at-risk countries. In Oceania, several Pacific Island countries (PICs) may be particularly vulnerable to negative impacts from fisheries supply chain disruptions, despite their central role in supplying global tuna. The region depends heavily on food imports, faces rising unhealthy food consumption, and experiences ongoing diet-related health challenges. PICs often act as “source” countries, supplying seafood while receiving few social or health benefits in return. In this talk, I will share both current progress and future directions. Overall, this study combines consumption and nutrient data from the Aquatic Resources in Trade Database and the Aquatic Food Composition Database to trace the flow of fisheries-derived nutrients in and out of PICs. I’ve examined the roles that countries play in these trade networks (sources, exporters, or consumers), the nutritional implications for local populations, and the structure of Pacific fisheries trade. Initial results indicate that the Pacific trade network is structurally distinct from the global network: it is sparser, more disconnected, and more asymmetric. PICs generally experience net outflows of key nutrients, especially protein, vitamin B12, and fatty acids, highlighting their role as suppliers to other regions. Yet, domestic production and consumption still account for a meaningful share of nutrient retention, revealing both vulnerability and resilience. Country-level outcomes also appear to be shaped by fisheries and trade agreements. Looking ahead, I plan to deepen this analysis through network modeling and statistical approaches to examine how social-ecological factors influence nutrient trade flows, and what health impacts may emerge from these international food systems. These insights could help inform equitable development strategies for blue food systems in the Pacific and beyond.
