Eikeset AM, Richter AP, Dunlop E, Dieckmann U, Stenseth NC. 2013. Economic repercussions of fisheries-induced evolution. Proceedings of the National Academy of Science of the United States of America. ISSN 0027-8424. 110(30):12259–12264. doi:10.1073/pnas.1212593110 Relevance: The optimal fishing mortality is almost identical for the evolutionary and nonevolutionary model and substantially lower than what it has been historically. Therefore, the costs of ignoring evolution under optimal management regimes are negligible. However, if fishing mortality is as high as it has been historically, evolutionary changes may result in economic losses, but only if the fishery is selecting for medium-sized individuals. Because evolution facilitates growth, the fish are younger and still immature when they are susceptible to getting caught, which outweighs the increase in productivity due to fish spawning at an earlier age.
Eikeset AM, Richter AP, Dankel D, Dunlop E, Heino MP, Dieckmann U, Stenseth NC. 2013. A bio-economic analysis of harvest control rules for the Northeast Arctic cod fishery. Marine Policy. ISSN 0308-597X. 39:172–181. doi:10.1016/j.marpol.2012.10.020 Relevance: This paper show that the current Harvest control rules (HCR) does in fact comes very close to maximizing profits. Furthermore, the results reveal that the HCR that maximizes profits is the most precautionary one among the considered HCRs. Finally, the HCR that maximizes yield leads to un-precautionary low levels of biomass. In these ways, the implementation of the HCR for NEA cod can be viewed as a success story that may provide valuable lessons for other fisheries.

Evolutionary impact assessment: accounting for evolutionary consequences of fishing in an ecosystem approach to fisheries management. Fish and Fisheries. ISSN 1467-2960. 1–32. doi:10.1111/faf.12007 Relevance: We describe the evolutionary impact assessment (EvoIA) as a structured approach for assessing the evolutionary consequences of fishing and evaluating the predicted evolutionary outcomes of alternative management options. EvoIA can contribute to the ecosystem approach to fisheries (EAF) by clarifying how evolution may alter stock properties and ecological relations, support the precautionary approach to fisheries management by addressing a previously overlooked source of uncertainty and risk, and thus contribute to sustainable fisheries.

ISSN 0171-8630. 480:199–203. doi:10.3354/meps10314 Relevance: The studies focus on how temperature- and fishing- induced changes in spatial and demographic population structure affect recruitment and population growth rate. The results suggest common patterns, but also highlight differences in the relative importance of fishing and climate among the populations and ecosystems examined.
Diekert FK. 2013. The growing value of age: exploring economic gains from age-specific harvesting in the Northeast Arctic cod fishery. Canadian Journal of Fisheries and Aquatic Sciences. Relevance: The importance of a fish stock’s age structure is increas- ingly recognized in economics and ecology. Still, current policies predominantly rely on measures of the aggregate biomass. Here, a detailed bio-economic model is calibrated on the Northeast Arctic cod (Gadus morhua) fishery to assess the efficiency gains from controlling gear selectivity and explore them under a suite of different scenarios. While the absolute size of economic gains varies drastically with the particular biological modeling assumptions, the relative economic gains from age-differentiated management show that it is high time to move beyond traditional reference points.
Boonstra WJ, de Boer FW. 2013. The historical dynamics of social- ecological traps. AMBIO. doi:10.1007/s13280-013-0419-1 Relevance: This paper takes stock of studies using the trap metaphor. It argues that the concept includes time and history in the analysis, but only as background conditions and not as a factor of causality. Based on this comparison it concludes that conjunction of social and environmental events contributes profoundly to the production of trap processes. The paper further discusses the implications of this conclusion for policy intervention and outlines how future research might generalize insights from historical–sociological studies of traps.

Nature Climate Change, 5(2), 89–92. http://dx.doi.org/10.1038/nclimate2471 Relevance: This paper is a highly relevant output from the Nordic Center of Excellence ’NorMER’ as it draws together senior scientists from both within NorMER and beyond in an effort to illustrate the ultimate goals of NorMER, namely to illustrate and understand the large-scale processes driving our Nordic marine regions under the influence of climate change. At the same time the paper presents novel opportunities and grand challenges for a future enlarged and deepened multidisciplinary Nordic research as a global show-case of adaptation to climate change scenarios in different regions with varying responses to the predicted climate changes.
Richter A, Grasman J. 2013. The transmission of sustainable harvesting norms when agents are conditionally cooperative. Ecological Economics, 93, 202–209. doi:10.1016/j.ecolecon.2013.05.013 Relevance: One of the key properties of marine systems is that social and natural processes are intrinsically linked and mutually influence each other. We develop a theoretical model that portrays a small community having joint access to a common resource, such as a fish stock. Individual agents face the temptation of higher profits by overexploiting the resource, while the diffusion of norms of cooperation takes place via interpersonal relations. Agents remain conditionally cooperative, unless other individuals are misbehaving already. We can observe a bubble of conditional cooperators slowly building up followed by a sudden burst, which means that a transition from a cooperative social norm to non-cooperation occurs. Interestingly, we find that the same community goes through such a transition repeatedly over long time spans — history thus repeats itself in the form of the creation and erosion of social capital.

Philosophical Transactions of the Royal Society B: Biological Sciences, 370(1659), 20130273–20130273. doi:10.1098/rstb.2013.0273 Relevance: Anthropogenic impacts, such as climate change, increase the processes that can drive marine systems to suddenly shift to persistent new regimes. This paper assesses the patterns of co-occurrence of drivers and ecosystem service consequences of marine regime shifts in order to inform better management strategies.
Woods PJ, Holland DS, Marteinsdóttir G, Punt AE. 2015. How a catch–quota balancing system can go wrong: an evaluation of the species quota transformation provisions in the Icelandic multispecies demersal fishery ICES J. Mar. Sci.: fsv001v1-fsv001
Woods PJ, Bouchard C, Holland DS, Punt AE, Marteinsdóttir, G. 2015. Catch-quota balancing mechanisms in the Icelandic multi-species demersal fishery: Are all species equal? Marine Policy, 55, 1–10. doi:10.1016/j.marpol.2015.01.004 Relevance: This set of papers (Woods 2014 and Woods 2015) analyzes regulations in the Icelandic demersal fishery that increase the industry's ability to adapt to unexpected outcomes of fishing (i.e., when the species composition caught does not exactly match the quota available). The first paper (Woods et al. 2015 in Marine Policy) establishes that the provisions have often been used but with no obvious detrimental effects on sustainability of fisheries resources, even though the increased adaptability also allows for routes of potential overexploitation. The second paper (Woods et al. 2015 in ICES J Mar Sci) highlights the conditions under which the risk of overexploitation is increased, so that situations leading to unintended overexploitation can be monitored for while implementing such a system in other locations. Therefore, they directly contribute to development of fisheries management policies that incorporate an ability to adapt to changing conditions of ocean resources while avoiding risks of overexploitation and decreased profit

Blenckner T, Kannen A, Barausse A, Fischer C, Heymans J, Luisetti T, Todorova V, Valman M, Mee L. 2015. Past and future challenges in managing European seas. Ecology and Society 20(1): 40. http://dx.doi.org/10.5751/ES-07246-200140 Relevance: We focus on existing examples from social–ecological systems of European seas that can be used to inform and advise future management. Examples from the Black Sea and the Baltic Sea on long-term ecosystem changes caused by eutrophication and fisheries, as well as changes in management institutions, illustrate nonlinear dynamics in social–ecological systems. Furthermore, we present two major future challenges, i.e., climate change and energy intensification, that could further increase the potential for nonlinear changes in the near future. Practical tools for managers to address these challenges are presented, such as ensuring learning, flexibility, and networking in decision-making processes across sectors and scales.
