Sustainable development aspires to "leave no one behind"1. Even so, limited attention has been paid small-scale fisheries (SSF) and their importance in eradicating poverty, hunger malnutrition. Through a collaborative multidimensional data-driven approach, we have estimated that SSF provide at least 40% (37.3 million tonnes) of global catches 2.3 billion people with, on average, 20% dietary intake across six key micronutrients essential for human health. Globally, the livelihood 1 every 12...
Summary The size spectrum of an ecological community characterizes how a property, such as abundance or biomass, varies with body size. Size spectra are often used ecosystem indicators marine systems. They have been fitted to data from various sources, including groundfish trawl surveys, visual surveys fish in kelp forests and coral reefs, sediment samples benthic invertebrates satellite remote sensing chlorophyll. Over the past decades, several methods fit data. We document eight methods,...
Abstract Ecological communities are reorganizing in response to warming temperatures. For continuous ocean habitats this reorganization is characterized by large‐scale species redistribution, but for tropical discontinuous such as coral reefs, spatial isolation coupled with strong habitat dependence of fish imply that turnover and local extinctions more significant mechanisms. In these systems, transient marine heatwaves causing bleaching profoundly altering structure, yet despite severe...
Fishing pressure on coral reef ecosystems has been frequently linked to reductions of large fishes and fish biomass. Associated impacts overall community structure are, however, less clear. In size-structured aquatic ecosystems, fishing are commonly quantified using size spectra, which describe the distribution individual body sizes within a community. We examined spectra biomass communities at 38 US-affiliated Pacific islands that ranged in human presence from near pristine population...
Abstract Coral reef ecosystems are among the first to fundamentally change in structure due climate change, which leads questioning of whether decades knowledge regarding management is still applicable. Here we assess ecological responses no-take marine reserves over two decades, spanning a major climate-driven coral bleaching event. Pre-bleaching reserve were consistent with large literature, higher cover, more species fish, and greater fish biomass, particularly upper trophic levels....
Fish are rich in bioavailable micronutrients, such as zinc and iron, deficiencies of which a global food security concern.1Thilsted S.H. Thorne-Lyman A. Webb P. Bogard J.R. Subasinghe R.

Seafood is an important source of bioavailable micronutrients supporting human health, yet it unclear how micronutrient production has changed in the past or climate change will influence its availability. Here combining reconstructed fisheries databases and predictive models, we assess nutrient availability from mariculture project their futures under change. Since 1990s, availabilities iron, calcium omega-3 seafood for direct consumption have increased but stagnated protein. Under change,...
Antarctic krill embryos and larvae were experimentally exposed to 380 (control), 1000 2000 µatm p CO 2 in order assess the possible impact of ocean acidification on early development krill. No significant effects detected embryonic or larval behaviour at ; however, was disrupted before gastrulation 90 per cent embryos, no hatched successfully. Our model projections demonstrated that Southern Ocean sea water could rise up 1400 krill's depth range under IPCC IS92a scenario by year 2100...
Wild-caught fish are a bioavailable source of nutritious food that, if managed strategically, could enhance diet quality for billions people. However, optimising nutrient production from the sea has not been priority, hindering development nutrition-sensitive policies. With fisheries management increasingly effective at rebuilding stocks and regulating sustainable fishing, we can now begin to integrate nutritional outcomes within existing frameworks. Here, develop conceptual foundation...
Climate change is transforming coral reefs, threatening supply of essential dietary micronutrients from small-scale fisheries to tropical coastal communities. Yet the nutritional value reef and climate impacts on micronutrient availability remain unclear, hindering efforts sustain food nutrition security. Here, we measure nutrient content in fishes Seychelles show that fish are important sources selenium zinc contain levels calcium, iron, omega-3 fatty acids comparable with other...
Abstract Wild fish used as aquafeeds could be redirected towards human consumption to support sustainable marine resource use. Here we use mass-balance fish-in/fish-out ratio approaches assess nutrient retention in salmon farming and identify scenarios that provide more nutrient-rich food people. Using data on Norway’s farms, our study revealed six of nine dietary nutrients had higher yields wild for feeds, such anchovies mackerel, than farmed production. Reallocating one-third food-grade...
As climate changes increase heat stress on tropical ecosystems, the long-term persistence of coral reefs requires rapid recovery following bleaching events. Using extent cover return to a pre-bleaching baseline as benchmark, fast-growing and stress-tolerant growth forms suggests that can bounce back between repeated disturbances if given adequate time protection from anthropogenic disturbances. However, dynamics communities severe mass mortality are limited, particularly for fringing along...
Catch diversification, when fishers target several species of fish, can increase revenue and catch sizes in tropical fisheries.
Aquaculture expansion is expected to meet growing demand for sustainable animal-source foods. Yet marine-fed species already require millions of tonnes wild-caught fish feed, over 90% which are nutritious food-grade species. Allocating feed human consumption could reduce pressure on marine resources while increasing seafood production. We examine micronutrient flows (the transfer micronutrients from fish) in Scotland’s farmed salmon industry, particularly reliant feeds, show that 1–49%...
There is growing global support to conserve 30% of the planet by 2030, suggesting conservation efforts, in all their forms, are likely expand. It widely recognised that area-based management tools (ABMTs) can be ecologically effective yet, socioeconomic outcomes vary depending on social and governance context. Specifically, relationships between managed areas such as ABMTs human nutrition remain unclear. Using spatial ecological, socioeconomic, information from past 20 years, a Before-After...
Aquatic invertebrates are a diverse, nutrient-dense, and socio-ecologically important food whose contribution to human nutrition is frequently overlooked.

Abstract Herbivory is a key process on coral reefs, which, through grazing of algae, can help sustain coral‐dominated states frequently disturbed reefs and reverse macroalgal regime shifts degraded ones. Our understanding herbivory largely founded feeding observations at small spatial scales, yet the biomass structure herbivore populations more closely linked to processes which be highly variable across large areas, such as benthic habitat turnover fishing pressure. Though our spatiotemporal...
