Reframing the sustainable seafood narrative

Tlusty, M.F., P. Tyedmers, M. Bailey, F. Ziegler, P.J.G. Henriksson, C. Béné, S. Bush, R. Newton, F. Ashe, D. C. Little, M. Troell and M. Jonell. 2019. Reframing the sustainable seafood narrative. Global Environmental Change 59:101991..

The dominant sustainable seafood narrative is one where developed world markets catalyze practice improvements by fisheries and aquaculture producers that enhance ocean health. The narrow framing of seafood sustainability in terms of aquaculture or fisheries management and ocean health has contributed to the omission of these important food production systems from the discussion on global food system sustainability. This omission is problematic. Seafood makes critical...

Mapping diversity of species in global aquaculture

Metian, M., M. Troell, V. Christensen, J. Steenbeek, and S. Pouil. 2019. Mapping diversity of species in global aquaculture. Reviews in Aquaculture https://doi.org/10.1111/raq.12374.

Aquaculture is the world’s most diverse farming practice in terms of number of species, farming methods and environments used. While various organizations and institutions have promoted species diversification, overall species diversity within the aquaculture industry is likely not promoted nor sufficiently well quantified. Using the most extensive dataset available (FAO‐statistics) and an approach based on the Shannon Diversity index, this paper provides a method for...

Ecological and functional consequences of coastal ocean acidification: Perspectives from the Baltic-Skagerrak System

Havenhand, J.N., H.L. Filipsson, S. Niiranen, M. troell, A-C. Crépin, S. Jagers, D. Langlet, S. Matti, D. Turner, M. Winder, P. de Wit, and L.G. Anderson. 2019. Ecological and functional consequences of coastal ocean acidification: Perspectives from the Baltic-Skagerrak System. Ambio 48(8):831–854.

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) of species than ecosystems, more positive responses...

Combined climate and nutritional performance of seafoods

Hallström, E., K. Bergman, K. Mifflin, R. Parker, P. Tyedmers, M. Troell, and F. Ziegler. 2019. Combined climate and nutritional performance of seafoods. Journal of Cleaner Production 230:402-411.

National authorities in many countries advise their populations to eat more seafood, for health and sometimes for environmental purposes, but give little guidance as to what type of seafood should be consumed. The large diversity in species and production methods results in variability both in the nutritional content and in the environmental performance of seafoods. More targeted dietary advice for sustainable seafood consumption requires a...

Governing the salmon farming industry: Comparison between national regulations and the ASC salmon standard

Luthman, O., M. Jonell, and M. Troell. 2019. Governing the salmon farming industry: Comparison between national regulations and the ASC salmon standard. Marine Policy 106: 03534.

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 resources in feeds. As...

The role of seafood in sustainable and healthy diets

Troell, M., M. Jonell, and B. Crona. 2019. Scoping report: The role of seafood in sustainable and healthy diets. The EAT-Lancet Commission report through a blue lens .

Aquatic food has a vital role to play in creating a global food system that supports a healthy human population on a healthy planet, yet it has been largely neglected in global efforts to chart the future of food. The EAT-Lancet Commission report on healthy diets from sustainable food systems set scientific targets for healthy diets and environmentally sustainable global food systems. To accurately expand the EAT-Lancet report...

A diagnostic framework for equitable mariculture development in the Western Indian Ocean

Eriksson H., M. Troell, C. Brugere, M. Chadag, M. Phillips, and N. Andrew. 2019. A diagnostic framework for equitable mariculture development in the Western Indian Ocean. Australian Centre for International Agricultural Research Canberra, ACT. Pp 36.

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...
