Transforming sustainable aquaculture by applying circularity principles. Reviews in Aquaculture. https://doi.org/10.1111/raq.12860

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 ...

The biosphere crisis requires changes to existing business practices. We ask how corporations can become sustainability leaders, when constrained by multiple barriers to collaboration for biosphere stewardship. We describe how scientists motivated, inspired and engaged with ten of the world’s largest seafood companies, in a collaborative process aimed to enable science-based and systemic transformations (2015–2021). CEOs face...

Graells, T., Lambraki, I.A., Cousins, M., Léger, A., et.al. 2022. Studying Factors Affecting Success of Antimicrobial Resistance Interventions through the Lens of Experience: A Thematic Analysis. Antibiotics (Basel). 2022 May 10;11(5):639. doi: 10.3390/antibiotics11050639.

Antimicrobial resistance (AMR) affects the environment, and animal and human health. Institutions worldwide have applied various measures, some of which have reduced antimicrobial use and AMR. However, little is known about factors influencing the success of AMR interventions. To address this gap, we engaged health professionals, designers, and implementers of AMR interventions in an exploratory study to learn about their exp...

Troell, M., Henriksson, P.J.G., Buschmann, A.H., Chopin, T., Quahe, S. 2022. Farming the Ocean – Seaweeds as a Quick Fix for the Climate? Reviews in Fisheries Science and Aquaculture, https://doi.org/10.1080/23308249.2022.2048792

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 argument relate to ...

Aquaculture is a major producer of aquatic foods, contributes substantially to global food and nutrition security, and is likely to expand further in response to increasing demand from an increasingly populous and affluent world. Projections by Costello and colleagues suggest high growth potential for marine aquaculture (mariculture), alongside a relatively marginal increase in freshwater aquaculture. We contend that these pr...

Shepon, A., Makov, T., Hamilton, H.A., Müller, D.B., Gephart, J.A., Henriksson, P.J.G., Troell, M., Golden, C.D. 2021. Sustainable optimization of global aquatic omega-3 supply chain could substantially narrow the nutrient gap. Resources, Conservation and Recycling (181)

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 potential for nar...

Micronutrient deficiencies constitute a pressing public health concern, especially in developing countries. As a dense source of bioavailable nutrients, aquatic foods can help alleviate such deficiencies. Developing aquaculture that provides critical micronutrients without sacrificing the underlying environmental resources that support these food production systems is therefore essential. Here, we address these dual challenges...

Aquatic foods are increasingly being recognized as having an important role to play in an environmentally sustainable and nutritionally sufficient food system. Proposals for increasing aquatic food production often center around species, environments, and ambitious hi-tech solutions that mainly will benefit the 16% of the global population living in high-income countries. Meanwhile, most aquaculture species and systems suffer ...

Systematic reviews, sometimes including meta-analyses, are often presented as an approach for identifying healthy and sustainable diets. Here we explore to which extent systematic review protocols have been adopted by studies comparing environmental impacts of foods based on Life Cycle Assessment (LCA) results, and to which extent they comply with the PRISMA protocol for transparent reporting. Out of 224 studies screened, seve...

Brugere, C., Troell, M. & Eriksson, H. 2021. More than fish: Policy coherence and benefit sharing as necessary conditions for equitable aquaculture development. Marine Policy 123, 104271.

Aquaculture development is part of the Blue Economy narrative and it may offer opportunities for improving the well-being of coastal people and the wider population. However, unlocking its full potential is unlikely to occur through sole focus on increasing production. Using a framework for identifying the “people-policy gap” in aquaculture as a starting point, we introduce benefit sharing as a necessary and complementary conc...
