“…However, the request for enhanced stability of fishing opportunities and reduced uncertainty (Rindorf et al, 2016) is encompassed in the draft MAP proposal for the key commercial Baltic Sea fisheries (EU, 2016). The MAP incorporates the best scientific knowledge available, and it leaves space for trade-off analysis, as the MSY fishing mortalities (F MSY )-forming the basis for setting annual TACsare provided as a range of values for each of the stocks, instead of a non-negotiable F MSY point estimate.…”

“…During phases of low stock size, when a rebuilding of the stock biomass was urgently needed, eMEY-based TACs would have been closer to the realized political TAC decisions compared to the historical ICES advice. Furthermore, annual fluctuations in eMEY based TACs are much smaller than in the other two management options, and therefore best meet the objective of inter-annual stability of catches, which is often put forward by fishermen and managers (Rindorf et al, 2016). However, even under the relatively stable eMEY management, maximum year-to-year changes in TACs range from a reduction of −11.171 tons (−12%; year 1982/1983), to an increase of +6.283 tons (+26%; year 2011/2012).…”

Fishing is a social and economic activity, and consequently socio-economic considerations are important for resource management. While this is acknowledged in the theory of Ecosystem-Based Management (EBM) and its sector-specific development Ecosystem-Based Fisheries Management (EBFM), currently applied fishery management objectives often ignore economic considerations. Year-to-year management, however, implicitly responds to short-term economic interests, and consequently, regularly resorts to tactical short-term rather than strategic long-term decisions. The aim of this article is to introduce a new way of estimating management advice referred to as an "ecologically-constrained Maximum Economic Yield" (eMEY) strategy, which takes into account ecological criteria as well as short-to medium-term economic costs. We further illustrate what net cost reductions per year are possible applying the eMEY strategy compared with the existing way of setting total allowable catches (TACs). The eMEY approach aims at maximizing the economic benefits for the fishery as well as society (consumers), while safeguarding precautionary stock sizes. Using an age-structured optimization model parameterized for the Eastern Baltic cod case study, we find that application of eMEY advice results in more stability in catch advice. Quantification and visualization of the costs of deviating from eMEY advice offers a transparent basis for evaluating decision-making outcomes. The costs of overfishing are mainly borne by the commercial fishery, while fishing less than optimal is particularly costly for the processing industry and consumers. To foster the uptake of our eMEY approach in current advice given by the International Council for the Exploration of the Sea (ICES) and the EU fishery management system, we suggest an easy-to-implement scheme of providing integrated advice, also accounting for economic considerations.

“…In practice OY has played out as being applied on a stock-by-stock basis, but it does not have to be done that way. Several jurisdictions are exploring or have proposed a systems approach to broaden the stock-specific application of OY (e.g., Mueter and Megrey 2006;Fogarty et al 2012;Fogarty 2014;Rosenberg et al 2014;Gaichas et al 2017;Rindorf et al 2017aRindorf et al , 2017b.

Abstract:The discipline and practice of fisheries science and management have had an useful, successful, and interesting history. The discipline has developed over the past century and a half into a very reductionist, highly quantitative, socially impactful endeavor. Yet given our collective successes in this field, some notable challenges remain. To address these challenges, many have proposed ecosystem-based fisheries management that takes a more systematic approach to the management of these living marine resources. Here I describe systems theory and associated constructs underlying system dynamics, elucidate how aggregate properties of systems can and have been used, contextualize these aggregate features relative to optimal yield, and note how this approach can produce useful estimates and outcomes for fisheries management. I explore two contrasting examples where this approach has and has not been considered, highlighting the benefits of applying such an approach. I conclude by discussing ways in which we might move forward with a portfolio approach for both the discipline and practice of fisheries science and management.Résumé : La discipline et la pratique des sciences halieutiques et de la gestion des pêches ont une histoire utile, intéressante et couronnée de succès. La discipline est devenue, au cours du dernier siècle et demi, une entreprise très réductionniste, hautement quantitative et à forte incidence sociale. Malgré nos réussites collectives dans ce domaine, des défis notables demeurent. Pour relever ces défis, de nombreuses personnes ont proposé une gestion écosystémique des pêches qui adopte une approche plus systématique de gestion de ces ressources marines vivantes. Je décris la théorie des systèmes et les constructions associées qui sous-tendent la dynamique des systèmes, j'explique comment les propriétés groupées de systèmes peuvent être utilisées et l'ont été, je mets ces éléments groupés dans un contexte de rendement optimal et je souligne comment cette approche peut produire des estimations et des résultats utiles pour la gestion des pêches. J'explore deux exemples dans lesquels cette approche a, d'une part, été prise en considération et, d'autre part, ne l'a pas été, afin de souligner les avantages de son application. Je conclus en discutant d'avenues possibles pour l'avenir qui reposent sur une approche de portefeuille tant pour la discipline que pour la pratique des sciences halieutiques et de la gestion des pêches.

Fisher's preferences and trade‐offs between management options

et al. 2017

Failure to understand the potential responses of fishers to management measures creates a significant risk of revisiting the familiar scenario of perverse and unintended consequences of those measures. This paper reports on a choice experiment survey to evaluate fisher's preferences for various management measures proposed under the EU Common Fisheries Policy (CFP) reform process, but the conclusions have wider relevance as similar measures are used by comparable fleets in fisheries globally. The survey was conducted with fishers involved in mixed pelagic and demersal fisheries in Ireland, pelagic fisheries in Denmark and demersal fisheries in Greece. Fisheries management policies were characterized by five attributes designed both to cover the principal CFP reform proposals and to integrate ecological, social, economic and institutional factors affecting fisher's decisions. The study uses a random utility modelling framework to reveal the preferences of the fishers across the alternative policy attributes. Results show that while there are generally preferences both for healthy stocks and for maintaining the importance of fishing to the local community, strong interfishery preference differences exist. These differences are most notable in relation to a discard ban and to the use of individual transferable fishing rights, favoured in Denmark, but not in Ireland for instance. The strength of these interfishery differences supports the assertion that there are no panaceas in fisheries management and that solutions should be tailored within the context of specific fisheries. Not doing so could create a significant risk of inappropriately managed fisheries that may lead to unsustainable outcomes.
