| This paper applies a stochastic viability approach to a tropical small-scale fishery, offering a theoretical and empirical example of ecosystem-based fishery management approach that accounts for food security. The model integrates multi-species, multi-fleet and uncertainty as well as profitability, food production, and demographic growth. It is calibrated over the period 2006–2010 using monthly catch and effort data from the French Guiana's coastal fishery, involving thirteen species and four fleets. Using projections at the horizon 2040, different management strategies and scenarios are compared from a viability viewpoint, thus accounting for biodiversity preservation, fleet profitability and food security. The analysis shows that under certain... |

| Targets and limits for long-term management are used in fisheries advice to operationalize the way management reflects societal priorities on ecological, economic, social and institutional aspects. This study reflects on the available published literature as well as new research presented at the international ICES/Myfish symposium on targets and limits for long term fisheries management. We examine the inclusion of ecological, economic, social and institutional objectives in fisheries management, with the aim of progressing towards including all four objectives when setting management targets or limits, or both, for multispecies fisheries. The topics covered include ecological, economic, social and governance objectives in fisheries management, consistent... |

| Many social-ecological system(SES)-based approaches have been proposed to address environmental problems. Most social-ecological frameworks developed to date, however, lack clear operational linkages between humans and nature to efficiently guide SESs toward resilience. A conceptual framework designed to be operational is therefore necessary, as well as a network of research platforms with which to apply it. We defined explicit coupling processes that can be used as leverages to pilot an SES toward sustainability. We proposed to formalize an SES as a dynamic entity composed of two coupling interfaces, i.e., adaptive management and ecosystem services, both set within a landscape context to provide an actionable framework. These interfaces describe the way... |

| An Impact Assessment (IA) is a process aimed at structuring and supporting the development of policies. Besides the fact that IA assumes different features when applied to different sectors, really it should help policy makers in evaluating the contribution to the fisheries sustainability of new regulations. The recent improvements and development around the IA methodologies go more and more toward the concept of a Sustainability Impact Assessment (SIA). The evolution of IA in the fishery sector has followed the general and increasing need in having a more and more integrated type of analysis, focusing on the three dimensions of sustainability (environmental, economic and social). This paper synthesizes the methodology developed under the EU FP7 SOCIOEC... |

| This communication presents a global overview of Atlantic bluefin tuna biology, exploitation and management. The comparison between bluefin tuna and all other tuna species do show that this species is ranking number one among other tunas world wide in a wide range of its resources and fisheries characteristics. Bluefin tuna is for instance the gold winner in the category of fisheries (about 10,000 years of documented fisheries, the highest price in the market, the largest tuna taken), of its peculiar biology (large migration, homing, growth, etc.) and in the category of risks presently faced by the resource, because of its multiple scientific uncertainties still pending, its increasingly serious statistical problems and the heavy political context in the... |

| Aquaculture now produces more seafood than wild capture fisheries and this production is expected to at least double by 2050. Representing almost half of global production, marine aquaculture will contribute to sustainably feeding the growing humanity. However, climate change will undoubtedly challenge the future growth of marine aquaculture. Temperature and sea-level rise, shifts in precipitation, freshening from glacier melt, changing ocean productivity, and circulation patterns, increasing occurrence of extreme climatic events, eutrophication, and ocean acidification are all stressors that will influence marine aquaculture. The objective of this themed article set was to bring together contributions on the broad theme of the potential impacts,... |

| Like many tropical small-scale fisheries, the French Guiana coastal fishery is characterized by the high fish biodiversity of its ecosystem, the weak selectivity of the fleets exploiting the resources, and the heterogeneity of the vessels in terms of size and fishing techniques. The Rapfish method is used to assess sustainability within 11 fishery systems by means of 27 attributes relating to ecological, economic, social, and technological fields. Overall results indicate an average performance in the weak sustainability range. Comparisons made among the FSs show a gradient of sustainability performance from the western portion of the coast to the eastern portion. Several recommendations are formulated to raise the current “sustainability” status, such as... |

| This study aims to test whether exploitation affects tunas and tuna-like species displaying contrasting life history traits similarly. We first collected information on life history of 10 commercial Atlantic species and then compared this information using multivariate analysis. On one hand, tropical tunas are characterised by small to medium size, rapid growth, early age-at-maturity, long spawning duration and short life span. These species, therefore, display a rapid turnover, characteristic of r-selected species. On the other hand, temperate tunas display differing life history traits, i.e., large size, slow growth, late age-at-maturity, short spawning duration and long life span. The turnover of these species is slow and present characteristics similar... |

| This paper examines the effect of climate warming on the bio-economic performance of Bay of Biscay mixed fisheries and provides insights into the best management strategy for coping with global warming. To achieve this, a dynamic multi-species, multi-class, multi-fleets model is developed and calibrated using biological and environmental ICES and IPCC data. Fishing and economic data have been collected within the European DCF. The climate represented by the Sea Surface temperature is assumed to affect species recruitment. Three management strategies are then compared in terms of bio-economic outcomes: Status-Quo (SQ), Multi-species Maximum Sustainable Yield (MMSY), Multispecies Maximum Economic Yield (MMEY). Strategies are ranked with respect to two... |

| Until very recently, governments of many countries, as well as their supporting organizations, have primarily addressed the biological, technical and economic aspects of aquaculture. In contrast, social and cultural aspects of aquaculture production have taken a backseat. Drawing on the observation that aquaculture development in Western Societies has largely failed to address these social effects across different scales and contexts, this paper offers a new way of capturing and visualising the diverse social dimensions of aquaculture. It does so by testing the ability to operationalise a set of social dimensions based on categories and indicators put forward by the United Nations, using several case studies across the North Atlantic. Local/regional... |

| Bethel Children’s Home (BCH) is an orphanage, established in 2002 in Myanmar, for orphans, semiorphansfrom underprivileged families, and abandoned children. At the time of initiating this project for BCH, there were 22 children ranging from 5 to 18 years of age living there under the care of house parents. Originally supported by a US aid organization, BCH found it increasingly difficult to operate financially due to the accelerating Myanmar economy driving up the Myanmar currency and commodity prices. Thus, a 5-year project was proposed by the author, in January 2013, to help BCH become financially stable and self-sufficient. The ongoing project entails utilizing the land around BCH for implementing economic activities such as raising milk cows and... |

| This paper reviews the experience and status of coastal aquaculture of seaweeds, mollusks, fish and crustaceansin eastern Africa and the islands of the western Indian Ocean. In many respects, coastal aquaculture is still in itsinfancy in the region, and there is a pressing need toformulate development strategies aimed at improving theincome and assuring the availability of affordable protein tocoastal communities. This paper also draws from positive and negative experiences in other parts of the world. Therequirements of feed and fry, and the conversion ofmangroves are used to illustrate how some aquacultureactivities constitute a net loss to global seafood production.The paper presents both general and specific sustainability guidelines based on the... |

| The present report contains the proceedings of the INCO-DEV International Workshop on “Policy Options for the Sustainable Use of Coral Reefs and Associated Ecosystems” convened in Mombasa, Kenya, 19-22 June 2000. It was convened to address issues associated with the ongoing degradation of coral reefs and associated ecosystems. This degradation takes place inspite of an impressing body of research results and and increasing number of technical solutions becoming available. Policy options for the sustainable use are only feasible if they allow reconciling the requirements of conservation with the economic and social demands of the people relying on these natural resources. By its very nature this challenge of managing coral reef ecosystems sustainably calls... |

| En los últimos años, el recurso jaiba ha manifestado una significativa caída en las capturas comerciales. Un inadecuado manejo en el esfuerzo pesquero, entre otras influencias antrópicas, han incidido negativamente en la conservación de la diversidad biológica en las áreas tradicionales de pesca. En el marco del Proyecto para la protección del Ecosistema Sabana-Camaguey (ESC), se fomentó una nueva forma de explotar este recurso en su estado de “jaiba blanda o suave” que se potencia como una viable alternativa de sostenibilidad así como una importante fuente de empleo y divisas. Este estudio expone los resultados de la pesca exploratoria de jaiba en los últimos años en la costa norte de Vila Clara, así como información estadística de las... |
