Abstract The exceptional diversity of shallow‐water marine fishes contributes to the nutrition millions people worldwide through coastal wild‐capture fisheries, with different species having diverse nutritional profiles. Fishes in ecosystems are reservoirs micronutrients benefits human health. Yet, amount contained fish on coral reefs and shallow tropical waters is challenging estimate, caught by fisheries remain uncertain. To assess whether micronutrient deficiencies could be addressed specific management actions, we first require a quantification potentially available biodiverse reef assemblages. Here, therefore undertake broad heuristic assessment using ensemble distribution modelling identify potential mismatches derived from summarising landings data. We find mismatch between modelled estimates ecosystem one hand small‐scale Fisheries had lower than expected assemblage. Further, were selective for vitamin A, thus resulting trade‐off other micronutrients. Our results remained unchanged after accounting under‐sampling communities under‐reporting catches—two major sources uncertainty. This reported indicates that current fished not adequate fully inventories. However, some countries already towards mass, indicating policies target improved access, consumption leverage this existing high mass. Enhanced taxonomic resolution catches biodiversity inventories localised surveys improve understanding nature‐people linkages. Improving reporting monitoring assemblages will advance mismatches, which overall indicate weak uptake goals practices. decoupling social, economic, shaped around targets—but key achieve sustainable healthy planet both nature.

Nearly a billion people depend on tropical seascapes. The need to ensure sustainable use of these vital areas is recognised, as one 17 policy commitments made by world leaders, in Sustainable Development Goal (SDG) 14 ('Life below Water') the United Nations. SDG seeks secure marine sustainability 2030. In time increasing social-ecological unpredictability and risk, scientists policymakers working towards Asia-Pacific region know: (1) How are seascapes changing? (2) What can global society do about changes? (3) science together achieve seascape futures? Through horizon scan, we identified nine emerging research priorities that clarify potential contributions locations with high coral reef abundance. They include geological biological evolution adaptation; elucidating drivers mechanisms change; understanding how functions services produced, them; costs, benefits, trade-offs changing seascapes; improving technologies practices; learning govern manage for all; use, justice, human well-being; bridging communities epistemologies innovative, equitable, scale-crossing solutions; informing resilient futures through modelling synthesis.

However, studies focusing on nutrient supply aquatic often differ in nutrients they examine, potentially biasing their contribution to nutrition security leading ineffective policies or management decisions.

As a result, policymakers, managers, scientists fishing communities seeking guidance on how to holistically build resilience Numerous studies have highlighted key attributes in fisheries, yet concrete examples that explicitly link these social‐ecological outcomes lacking.
