Farmed salmon has become an important export commodity for many countries and regions. The expanding salmon aquaculture industry has, due to its rapid increase, resulted in environmental concerns, most notably relating to the interaction with wildlife, effects of effluents and discharges in local ecosystems, in some regions overuse of antibiotics and development of Antimicrobial Resistance (AMR) and high dependence on fish res...
Jonell, M., Tlusty, M., Troell, M., Rönnbäck, P., 2019 Certifying farmed seafood – a drop in the ocean or a ‘stepping-stone’ towards increased sustainability? In Sustainability Certification Schemes in the Agricultural and Natural Resources Sectors: Outcomes for society and the environment, Ed. Vogt, M., 323 pp. Oxon: Routledge
The sustainable seafood movement has gained increased momentum during recent years and while most eco-labelled seafood originates from capture fisheries, the fastest growth of seafood eco-certification can be observed in the aquaculture sector. The extent to which certification have overall positive environmental impacts however remains uncertain. This chapter provides an overview of the existing literature on aquaculture eco-...

Guiding the sustainable development of sectors within the blue economy is critical not only to the global goal of thriving life under water (SDG 14), but also across many other goals related to resources, poverty, health, equity and wellbeing. This is especially the case for island and coastal states, where oceans support daily subsistence, livelihoods and economic opportunities, in the face of poverty and food and nutrition i...

Major climate and ecological changes affect the world’s oceans leading to a number of responses including increasing water temperatures, changing weather patterns, shrinking ice-sheets, temperature-driven shifts in marine species ranges, biodiversity loss and bleaching of coral reefs. In addition, ocean pH is falling, a process known as ocean acidification (OA). The root cause of OA lies in human policies and behaviours drivin...

Ocean temperatures are rising; species are shifting poleward, and pH is falling (ocean acidification, OA). We summarise current understanding of OA in the brackish Baltic-Skagerrak System, focussing on the direct, indirect and interactive effects of OA with other anthropogenic drivers on marine biogeochemistry, organisms and ecosystems. Substantial recent advances reveal a pattern of stronger responses (positive or negative) o...

Food systems have the potential to nurture human health and support environmental sustainability; however, they are currently threatening both. Providing a growing global population with healthy diets from sustainable food systems is an immediate challenge. Although global food production of calories has kept pace with population growth, more than 820 million people have insufficient food and many more consume low-quality diet...

Springmann, M., Clark, M., Mason-D’Croz, D., Wiebe, K., Bodirsky, B.L., Lassaletta, L., de Vries, W., Vermeulen, S.J., Herrero, M., Carlson, K.M. and Jonell, M., 2018. Options for keeping the food system within environmental limits. Nature, 562(7728), p.519.
The food system is a major driver of climate change, changes in land use, depletion of freshwater resources, and pollution of aquatic and terrestrial ecosystems through excessive nitrogen and phosphorus inputs. Here we show that between 2010 and 2050, as a result of expected changes in population and income levels, the environmental effects of the food system could increase by 50–90% in the absence of technological changes and...
Buck, B. H. Troell, M.F., Krause, G., Angel, D.L., Grote, B., Chopin, T. 2018. State of the Art and Challenges for Offshore Integrated Multi-Trophic Aquaculture (IMTA). Front. Mar. Sci., 15 May 2018, DOI: https://doi.org/10.3389/fmars.2018.00165
By moving away from coastal waters and hence reducing pressure on nearshore ecosystems, offshore aquaculture can be seen as a possible step towards the large-scale expansion of marine food production. Integrated multi-trophic aquaculture (IMTA) in nearshore water bodies has received increasing attention and could therefore play a role in the transfer of aquaculture operations to offshore areas. IMTA holds scope for multi-use o...

Aquaculture has grown rapidly over the last three decades expanding at an average annual growth rate of 5.8% (2005–2014), down from 8.8% achieved between 1980 and 2010. The sector now produces 44% of total food fish production. Increasing demand and consumption from a growing global population are driving further expansion of both inland and marine aquaculture (i.e., mariculture, including marine species farmed on land). Howev...
