Transforming sustainable aquaculture by applying circularity principles
Chary, K., A-J. van Riel, A. Muscat, A. Wilfart, S. Harchaoui, M. Verdegem, R. Filgueira, M. Troell, P.J.G. Henriksson, I.J.M. de Boer, and G.F. Wiegertjes. 2023. Transforming sustainable aquaculture by applying circularity principles. Reviews in Aquaculture 16(2):656-673.
A circular economy is considered one way to reduce environmental impacts of human activities, by more efficient use of resources and recovery, resulting in less waste and emissions compared to linear take-make-dispose systems. Muscat et al. developed five ecological principles to guide biomass use towards a circular economy. A few studies have demonstrated environmental benefits of applying these principles to land-based food systems, but to...
Fuel use intensity of hilsa fisheries in the lower Meghna River estuary of Bangladesh
Zaman, A.U., P.J.G. Henriksson, and A. Al Mamun. 2023. Fuel use intensity of hilsa fisheries in the lower Meghna River estuary of Bangladesh. Fisheries Research 263:106684.
Among the species caught by small-scale fisheries in Bangladesh, hilsa (Tenualosa ilisha) is the most important by volume and of great cultural importance. Hilsa fishing boats have over the last decade been mechanized, enabling longer trips and larger hauls. This development has, however, also resulted in increased fishing pressure and increased reliance on fossil fuels. This study estimates the fuel use intensity (FUI) of hilsa fishing, calculated as fuel...
Lax – Hållbart och hälsosamt? (Salmon – Healthy and sustainable?)
Ziegler, F., S. Hornborg, M. Troell, P.J.G. Henriksson, and M. Jonell. 2023. Lax – Hållbart och hälsosamt? (Salmon – Healthy and sustainable?). SeaWin Policy Brief no. 6, SeaWin.
Sjömatslandet Sverige – Vart är vi på väg? (Seafood Sweden – Where are we going?)
Henriksson, P.J.G., M. Troell, M. Jonell, F. Ziegler, S. Hornborg, and K. Bergman. 2023. Sjömatslandet Sverige – Vart är vi på väg? (Seafood Sweden – Where are we going?). SeaWin Policy Brief no. 7, SeaWin .
Sveriges självhushållningsgrad av sjömat är för närvarande låg, men det finns potential för att öka inhemsk produktion och samtidigt öka sjömatens roll för omställning till ett mer hållbart livsmedelssystem. För att möjliggöra detta krävs att sjömatsbranschen, dagligvaruhandeln och konsumenter vågar utmana sina vanor, samt att myndigheter tar ett bredare systemperspektiv och planerar långsiktigt.
Factors impacting antimicrobial resistance in the South East Asian food system and potential places to intervene: A participatory, One Health study
Lambraki, I.A., C.V. Mohan, M. Cousins, T. Graells, A. Léger, P.J.G. Henriksson, M.F. Troell, S. Harbarth, D. Wernli, P.S. Jørgensen, C.A Carson, E.J Parmley and S.E Majowicz. 2023. Factors impacting antimicrobial resistance in the South East Asian food system and potential places to intervene: A participatory, One Health study. Frontiers in Microbiology 13.
Background: With AMU projected to increase, South East Asia (SEA) is at high risk of experiencing disproportionate health, social, and economic burdens due to antimicrobial resistance (AMR). Our objective was to identify factors influencing AMR in SEA’s food system and places for intervention by integrating the perspectives of experts from the region to inform policy and management decisions. Materials and methods: We conducted two 6.5 h workshops and...
Antimicrobial resistance in southeast Asia: A participatory systems modelling approach
Lambraki, I., M. Chadag, M. Cousins, T. Graells, A. Léger, P. Henriksson, M. Troell, S. Harbarth, D. Wernli, P. S. Jørgensen, C. Carson, J. Parmley and S. Majwicz. 2022. Antimicrobial resistance in southeast Asia: A participatory systems modelling approach. International Journal of Infectious Diseases 116:14.
Purpose Our study purpose was to identify (1) the underlying causal system of factors influencing antimicrobial resistance (AMR) development and spread in South East Asia (SEA) and (2) places to intervene by integrating diverse perspectives to find context-specific solutions. Methods & Materials Using a complex adaptive systems lens and participatory, qualitative, systems modelling approach, we conducted 2 participatory workshops and 2 interviews involving AMR experts...
Farming the Ocean – Seaweeds as a Quick Fix for the Climate?
Troell, M., P.J.G. Henriksson, A.H. Buschmann, T. Chopin and S. Quahe. 2022. Farming the Ocean – Seaweeds as a Quick Fix for the Climate?. Reviews in Fisheries Science & Aquaculture .
Finding ways to keep global warming under 1.5 degrees Celsius is urgent and will need a portfolio of solutions. Seaweeds are marine photosynthetic organisms that humans harvest either from the wild or farm, to be used in many applications and providing various ecosystem services. Large scale farming of seaweeds for absorbing carbon has lately been promoted as a climate “fix”. The major shortcomings of this...
Aquaculture will continue to depend more on land than sea

Life cycle assessment of Indonesian canned crab (Portunus pelagicus)
Wiloso, E.I., M. Romli, B.A. Nugraha, A.R. Wiloso, A.A.R. Setiawan, and P.J.G. Henriksson. 2022. Life cycle assessment of Indonesian canned crab (Portunus pelagicus). Journal of Industrial Ecology 2030:1-14.
Indonesia is an archipelagic country with abundant marine wealth that makes it the world’s second largest producer of fish after China. While most of Indonesia’s capture marine fisheries (80%) are consumed domestically, around 90% of blue swimming crab (BSC) products are exported, mainly in cans. This makes up almost half of all BSC products on the global market, with the United States and the European...
Sustainable optimization of global aquatic omega-3 supply chain could substantially narrow the nutrient gap
Shepon, A., T. Makov, H.A. Hamilton, D.B. Müller, J.A. Gephart, P.J.G. Henriksson, M. Troell, and C.D. Golden. 2022. Sustainable optimization of global aquatic omega-3 supply chain could substantially narrow the nutrient gap. Resources, Conservation and Recycling 181:106260.
Omega-3 EPA and DHA fatty acids are vital for human health, but current human nutritional requirements are greater than supply. This nutrient gap is poised to increase as demand increases and the abundance of aquatic foods and the amount of omega-3 they contain may dwindle due to climate change and overfishing. Identifying and mitigating loss and inefficiencies across the global aquatic supply chain has great...
