  abstract = {{T}he exceptional diversity of shallow-water marine fishes contributes to the nutrition of millions of people worldwide through coastal wild-capture fisheries, with different species having diverse nutritional profiles. {F}ishes in ecosystems are reservoirs of micronutrients with benefits to human health. {Y}et, the amount of micronutrients contained in fish species on coral reefs and in shallow tropical waters is challenging to estimate, and the micronutrients caught by fisheries remain uncertain.



{T}o assess whether micronutrient deficiencies could be addressed through specific fisheries management actions, we first require a quantification of the potentially available micronutrients contained in biodiverse reef fish assemblages. {H}ere, we therefore undertake a broad heuristic assessment of available micronutrients on tropical reefs using ensemble species distribution modelling and identify potential mismatches with micronutrients derived from summarising coastal fisheries landings data. {W}e find a mismatch between modelled estimates of micronutrients available in the ecosystem on the one hand and the micronutrients in small-scale fisheries landings data. {F}isheries had lower micronutrients than expected from fishes in the modelled assemblage. {F}urther, fisheries were selective for vitamin {A}, thus resulting in a trade-off with other micronutrients. {O}ur results remained unchanged after accounting for the under-sampling of fish communities and under-reporting of small-scale fisheries catches?two major sources of uncertainty.



{T}his reported mismatch indicates that current estimates of fished micronutrients are not adequate to fully assess micronutrient inventories. {H}owever, small-scale fisheries in some countries were already selective towards micronutrient mass, indicating policies that target improved access, distribution and consumption of fish could leverage this existing high micronutrient mass. {E}nhanced taxonomic resolution of catches and biodiversity inventories using localised species consumption surveys could improve understanding of nature-people linkages. {I}mproving fisheries reporting and monitoring of reef fish assemblages will advance the understanding of micronutrient mismatches, which overall indicate a weak uptake of nutritional goals in fisheries practices.{T}he decoupling between micronutrients in ecosystems and in fisheries catches indicates that social, economic, and biodiversity management goals are not shaped around nutritional targets?but this is key to achieve a sustainable and healthy planet for both people and nature.},
