Purcell, S.W., Crona, B.I., Lalavanua W., Eriksson, H. 2017. Distribution of economic returns in small-scale fisheries for international markets: A value-chain analysis. Marine Policy Volume 86, December 2017, Pages 9-16 DOI: 10.1016/j.marpol.2017.09.001
Small-scale fishers are often believed to receive marginal earnings for seafood relative to other value- chain actors but proportionate incomes across different traded species are rarely compared. This study compares value chains for 15 species of sea cucumbers between Fiji and Kiribati using data collected on sale prices of dried products (bêche-de-mer) from fishers to middlemen and exporters, export prices and market retail ...
Troell, M., Eide, A., Isaksen, J., Hermansen, Ø., Crépin, A-C. 2017. Seafood from a changing Arctic. Ambio 46(Suppl 3): 368. https://doi.org/10.1007/s13280-017-0954-2
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...
Edgar, G.J., Alexander, T.J., Lefcheck, J. et. al 2017. Abundance and local-scale processes contribute to multi-phyla gradients in global marine diversity. Sci. Adv. 2017;3: e1700419
Among the most enduring ecological challenges is an integrated theory explaining the latitudinal biodiversity gradient, including discrepancies observed at different spatial scales. Analysis of Reef Life Survey data for 4127 marine species at 2406 coral and rocky sites worldwide confirms that the total ecoregion richness peaks in low latitudes, near +15°N and −15°S. However, although richness at survey sites is maximal near th...
Lu, Y-H., Yagi, N., Blasiak, R. 2017. Factors contributing to effective management in the Sakuraebi (Sergia lucens) fishery of Donggang, Taiwan. Marine Policy Volume 86, December 2017, Pages 72–81 DOI: 10.1016/j.marpol.2017.09.004
An in-depth assessment was conducted on the functioning of a Taiwanese Sakuraebi (Sergia lucens) fishery management institution to understand the role of leadership in the context of long-term incentive creation. Interviews with relevant stakeholders and statistical analysis of fisheries data indicated that the daily vessel quota system and fishers’ collective efforts to influence the market resulted in increased sales value, ...
Orach, K., Schlüter, M., Österblom, H. 2017. Tracing a pathway to success: How competing interest groups influenced the 2013 EU Common Fisheries Policy reform. Environmental Science & Policy Volume 76, October 2017, Pages 90-102
Adaptation of environmental policies to often unexpected crises is an important function of sustainable governance arrangements. However the relationship between environmental change and policy is complicated. Much research has focused on understanding institutional dynamics or the role of specific participants in the policy process. This paper draws attention to interest groups and the mechanism through which they influence p...

Österblom, H., Jouffray, J.-B., Folke, C., Rockström, J. 2017. Emergence of a global science-business initiative for ocean stewardship. Proceedings of the National Academy of Science, USA.
The ocean is under considerable pressure originating from diverse human activities on land and in the water. While substantial literature has focused on how science interacts with policy, relatively little is known about interactions between science and business. Here, we describe: ( i ) the process of identifying “keystone actors” in marine ecosystems, namely globally operating corporations engaged in fisheries and aquacultu...
Henriksson, P.J.G., M. Dickson, A.N. Allah AN, D. Al-Kenawy, M. Phillips. 2017. Benchmarking the environmental performance of best management practice and genetic improvements in Egyptian aquaculture using life cycle assessment. Aquaculture doi:10.1016/j.aquaculture. 2016.09.051.
Egyptian aquaculture is gaining importance as an affordable and nutritious source of animal protein among Egyptians. Nile tilapia dominates production (77% of total production), followed by carps (17%) and mullets (11%). Egyptian tilapia farmers are, however, facing challenges with regards to financial viability and poor water quality. Fish farms are also contributing towards water pollution and other environmental impacts. In...
Österblom, H., B.I. Crona, C. Folke, M. Nyström, M. Troell. 2017. Marine ecosystem science on an intertwined planet. Ecosystems doi:10.1007/s10021-016-9998-6.
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...
Van Holt, T., B. Crona, J.C. Johnson, S. Gelcich. 2017. The consequences of landscape change on fishing strategies. Science of the Total Environment doi.org.ezp.sub.su.se/10.1016/j.scitotenv.2016.10.052.
We show how land-use change can affect fisher-harvesting behavior. We test whether fisher harvesting behavior can be predicted by landscape change patterns at local (~ 200 km) and regional (~ 1200 km) levels. Our data suggest that fishers harvesting in areas near tree plantations reduced benthic-invertebrate harvests in favor of demersal and pelagic finfish that are usually located further offshore. Fishers' management areas, ...
