The present paper analyzes the suitability of weak and strong sustainability assessment in the context of fisheries management. This topic is a mainstream issue in the field of ecological economics, but its application to fisheries is rather unexplored, even though fisheries have been the focus of many pioneering studies related to natural resource management. An overview of the current debate in the topic together with an application of a multi-disciplinary technique designed to assess fisheries sustainability (Rapfish) allows the closing of this gap. This is achieved by looking to the potential trade-offs among the multiple dimensions of fisheries sustainability and by analyzing the role of critical thresholds in such an assessment. The study of the Basque trawl fisheries operating in the North East Atlantic in the period 1996-2005 shows that the utility of weak sustainability is limited to the comparison of sustainability between fisheries. In contrast it is found that it is the strong sustainability concept together with the definition of critical thresholds that provides management with the tools for improved management and policy within a fishery. © 2010 Elsevier B.V.

While fishing resources available to fishermen are becoming increasingly scarce, management actions that regulate these resources are becoming more restrictive, to such an extent that some fisheries remain closed for years. The anchovy fishery in the Bay of Biscay, which was closed for 5 years, from 2005 to 2009, is one of the most important sources of revenue for the Basque pelagic purse-seiner fleet. Throughout the course of this closure the fleet was forced to find alternative revenue streams. In the present study, the fishing alternatives were analysed before and during the anchovy fishery closure, defining an adaptability indicator to measure the ability of the fleet to cope with fisheries closures. Four differently-behaved segments were found within the purse-seiner fleet. Only one of these segments managed to maintain the same level of turnover during the anchovy closure, while the others could not reach a minimum level of adaptability. Compensation of the fishery closure through financial aid was studied, analysing the impact that public aid had on the profit of each segment and on the adaptability indicator. © 2012 EDP Sciences, IFREMER, IRD.

This article applies the Rapfish methodology, a non-parametric and multi-disciplinary technique, with the objective of defining and evaluating a Sustainability Index of the Basque purse-seine fleet, fishing tropical tunain the Indian and Atlantic Oceans. The estimated Sustainability Index for the fleet fishing in the Indian Ocean is above a critical sustainability threshold and improves between 1998 and 2009. The opposite occurs for the fleet in the Atlantic Ocean. The influence of the growing use of Fish Aggregating Devices on the behaviour of fishers in the Indian Ocean is also analysed.
