Cao, L., R. Naylor, P. Henriksson, D. Leadbitter, M. Troell, W. Zhang. 2017. Rebuttal to Han et al., Reviews in Aquaculture, 2016 doi: 10.13140/RG.2.2.27925.93928.
As authors of " China's aquaculture and the world's fisheries " (Cao et al., Science, 2015), we would like to dispute several claims presented in " A revisit to fishmeal usage and associated consequences in Chinese aquaculture " (Han et al., Reviews in Aquaculture, 2016), as the latter seriously misrepresents the intent and substance of our Science paper. In their review, Han and colleagues argue that although China's aquacult...

Global seafood provides almost 20% of all animal protein in diets, and aquaculture is, despite weakening trends, the fastest growing food sector worldwide. Recent increases in production have largely been achieved through intensification of existing farming systems, resulting in higher risks of disease outbreaks. This has led to increased use of antimicrobials (AMs) and consequent antimicrobial resistance (AMR) in many farming...

We review current knowledge about climate change impacts on Arctic seafood production. Large-scale changes in the Arctic marine food web can be expected for the next 40–100 years. Possible future trajectories under climate change for Arctic capture fisheries anticipate the movement of aquatic species into new waters and changed the dynamics of existing species. Negative consequences are expected for some fish stocks but others...
Gordon, L., Bignet, V., Crona, B. et.al. 2017. Rewiring food systems to enhance human health and biosphere stewardship. Environ. Res. Lett. 12 100201
Food lies at the heart of both health and sustainability challenges. We use a social-ecological framework to illustrate how major changes to the volume, nutrition and safety of food systems between 1961 and today impact health and sustainability. These changes have almost halved undernutrition while doubling the proportion who are overweight. They have also resulted in reduced resilience of the biosphere, pushing four out of s...

Marine ecosystem science has developed since the 1940s, when humans obtained the ability to spend substantial time underneath the surface of the ocean. Since then, and drawing on several decades of scientific advances, a number of exciting research frontiers have emerged. We find: Understanding interacting drivers of change, Identifying thresholds in ecosystems, and Investigating social-ecological dynamics to represent particu...
Gephart, J. A., Troell, M., Henriksson, P.J.G., Beveridg, M.C.M, Verdegem, M., Metian, M., Mateos, L.D. Deutsch. L. 2017. The’seafood gap’ in the food-water nexus literature—issues surrounding freshwater use in seafoodproduction chains, Advances in Water Resources (2017), doi: 10.1016/j.advwatres.2017.03.025
Freshwater use for food production is projected to increase substantially in the coming decades with population growth, changing demographics, and shifting diets. Ensuring joint food-water security has prompted efforts to quantify freshwater use for different food products and production methods. However, few analyses quantify freshwater use for seafood production, and those that do use inconsistent water accounting. This inh...

Sudden disruptions, or shocks, to food production can adversely impact access to and trade of food commodities. Seafood is the most traded food commodity and is globally important to human nutrition. The seafood production and trade system is exposed to a variety of disruptions including fishery collapses, natural disasters, oil spills, policy changes, and aquaculture disease outbreaks, aquafeed resource access and price spike...
Troell, M., Ziegler, F., Henriksson, P. 2016. Is fish a fish - adding fish to the global food sustainability transformation. Science 16 Sep 2016: Vol. 353, Issue 6305, pp. 1202-1204 DOI: 10.1126/science.aah4765
The Perspective on food sustainability (T. Garnett, 16 September, 353/6305) gives valuable insights related to links between dietary choices, environmental impacts and health. Substituting meat with fish could, as stated, only result in a transfer of impacts. If, however, fish is caught sustainably, respecting biological limits and using smart fishing methods, capture fisheries can produce low-impact food without requiring lan...

Eco-certification has become an increasingly popular market-based tool in the endeavor to reduce negative environmental impacts from fisheries and aquaculture. In this study, we aimed at investigating which psychological consumer characteristics influence demand for eco-labeled seafood by correlating consumers’ stated purchasing of eco-labeled seafood to nine variables: environmental knowledge regarding seafood production, fam...
