Nutrient bioavailability is the missing ingredient connecting food systems to nutrition security and environmental sustainability

Nicholas, K. M., A. Tone , T. Beal, J. Zamborain-Mason, H. Eneroth, V. Öhrvik , M. Troell, and C. D. Golden. 2026. Nutrient bioavailability is the missing ingredient connecting food systems to nutrition security and environmental sustainability. The American Journal of Clinical Nutrition 123(5).

Increasing attention has focused on the capacity of current global food systems to provide accessible, affordable, and sustainable food to a growing human population, particularly amid ongoing climate and environmental changes. Concerns about the dysfunction of the global food system have led to the development of several initiatives to estimate current and predict future global nutrient supplies based on various climate, production, and demand scenarios....

Global nutritional equity of fishmeal and aquaculture trade flows

Elsler, L. G., J. A. Gephart, J. Zamborain-Mason, T. Cashion, M. Troell, R. L. Naylor, R. Agrawal Bejarano, and C. D. Golden. 2026. Global nutritional equity of fishmeal and aquaculture trade flows. PNAS 123(7).

Aquaculture, the single fastest growing food sector, is central to achieving key SustainableDevelopment Goals (e.g., SDG 2: Zero Hunger). Linking the nutrient compositionof >2,800 aquatic species with >2 million fishmeal and farmed fish transactions ininternational aquatic food trade between 2015 and 2019, we examined aquaculture’snutritional flows and distributional equity. We found that aquaculture provided adequateintakes for nearly a quarter of a million individuals, on average,...

Aquaculture requires special consideration in National Action Plans for Antimicrobial Resistance

Desbois A. P., L. A. Brunton, P. J. G. Henriksson, O. Luthman, M. Troell, and D. M. Green. 2025. Aquaculture requires special consideration in National Action Plans for Antimicrobial Resistance. Science of The Total Environment 958:177785.

Antimicrobial resistance (AMR) demands collective action to reduce and mitigate its threats. The Quadripartite collaboration of the World Health Organization (WHO), Food and Agriculture Organization of the United Nations (FAO), United Nations Environment Programme (UNEP) and World Organization for Animal Health (WOAH) has led development and implementation of National Action Plans (NAPs) that describe approaches each country will take to tackle AMR. All antimicrobial users...

Towards sustainable antibiotic use in aquaculture and antimicrobial resistance: participatory experts’ overview and recommendations

Farias, D. R., R. Ibarra, R. Estévez, M. Tustly, C. V. Mohan, O. Nyberg, M. Troell, R. Avendaño-Herrera and W. Norden. 2024. Towards sustainable antibiotic use in aquaculture and antimicrobial resistance: participatory experts’ overview and recommendations. Antibiotics 13(9): 887.

Notably, 56 worldwide experts gathered for the Antimicrobial Assessment on Global Aquaculture Production (AGAP) series of workshops to (1) evaluate the current state of knowledge on antimicrobial use and identify existing gaps; (2) formulate strategies to identify ecologically relevant impact indicators and establish thresholds for assessment; (3) identify pivotal socioeconomic factors and effective governance mechanisms essential for implementing monitoring practices in aquaculture and extending them...

Opportunities for blue food in a turbulent future – what’s ahead for a growing aquaculture industry?

Troell, M.. 2024. Opportunities for blue food in a turbulent future – what’s ahead for a growing aquaculture industry?. Bulletin of the European Association of Fish Pathologists 45(1).

The scale and speed of human activities and technological developments have substantially increased since the 1950s resulting in reshaping of the biosphere and moving humanity into a new geological epoch — the ”Anthropocene”. This is characterized by changes in several Earth system processes and structures on which human life depends. The global food system is a major driver of changes in the biosphere – for...

Global overview of national regulations for antibiotic use in aquaculture production

Luthman, O., D. Robb, P. J. G. Henriksson, P. S. Jørgensen, and M. Troell. 2024. Global overview of national regulations for antibiotic use in aquaculture production. Aquaculture International 32:9253–9270.

The intensifcation of aquaculture industries around the globe has led to increased susceptibility and exposure to diseases. To ensure the well-being of animals and the proftability of the industry, many aquaculture farms resort to antibiotic treatments. However, with the increasing presence of antimicrobial resistance (AMR), it has become important to regulate and limit the use of antibiotics, especially in animal production and regarding the antibiotics...

Globalization of wild capture and farmed aquatic foods

Gephart, J. G., R. Agrawal Bejarano, K. Gorospe, A. Godwin, C. D. Golden, R. L. Naylor, K. L. Nash, M. L. Pace, and M. Troell. 2024. Globalization of wild capture and farmed aquatic foods. Nature Communications 15:8026.

Aquatic foods are highly traded, with nearly 60 million tonnes exported in 2020, representing 11% of global agriculture trade by value. Despite the vast scale, basic characteristics of aquatic food trade, including species, origin, and farmed vs wild sourcing, are largely unknown due to the reporting of trade data. Consequently, we have a coarse picture of aquatic food trade and consumption patterns. Here, we present...

Competition for human edible feed resources in aquaculture – looking at tilapia farming

Chary, K., P. J. G. Henriksson, and M. Troell. 2024. Competition for human edible feed resources in aquaculture - looking at tilapia farming. Food Security 17:57-72.

Animal-source foods provide essential nutrients for humans, however, the use of nutrient-dense (i.e., high in nutrients but low in calories) and digestible resources for animal feeds is controversial as it may reduce the net contribution of farmed animals to global food supply, and hence to food security. Redirecting resources edible by humans to direct consumption as food can increase resource use efficiency and food supply,...

HIARA study protocol: impacts of artificial coral reef development on fisheries, human livelihoods and health in southwestern Madagascar

Golden, C.D. et al. 2024. HIARA study protocol: impacts of artificial coral reef development on fisheries, human livelihoods and health in southwestern Madagascar. Front. Public Health 12:1366110.

The Health Impacts of Artificial Reef Advancement (HIARA; in the Malagasy language, “together”) study cohort was set up in December 2022 to assess the economic and nutritional importance of seafood for the coastal Malagasy population living along the Bay of Ranobe in southwestern Madagascar. Over the course of the research, which will continue until at least 2026, the primary question we seek to answer is...
