| One of the current major scientific challenges to sustain social-ecological systems is to improve our understanding of the spatial and temporal dynamics of the relationships between biodiversity, ecosystem functioning and ecosystem services. Here, we analyse the bundles of ecosystem services supplied by three coastal ecosystems (coastal lagoons, coral reefs and sandy beaches) along a gradient of eutrophication. Based on a state-and-transition model, we analyses the dynamic responses of ecological communities to environmental change and management actions. Although few exceptions are highlighted, increasing eutrophication in the three ecosystem types leads to a degradation of the ecosystem service bundles, particularly for nutrient and pathogen... |

| Aquaculture is an economic activit y which is characterised by a great dependence on environmental conditions. Therefore, aquaculture development is subdued to institutional context which defines the rules for use and conservation of natural resources. This paper analyses the impact of marine environment regulations on economic operating of aquaculture enterprises and on industrial d ynamics. Because aquaculture enterprises use common goods, an economic approach of aquaculture has to take into account not only the relations between enterprises and environment, but also the relations between the enterprises themselves, through production externalities. In this study, several economic tools are considered in order to incite enterprises to integrate parr of... |

| Implementation of Ecosystem Based Management in fisheries has led to higher integration of knowledge in advices and higher engagement of stakeholders in the decision support Process. As part of the process, fisheries scientists contribute in different ways and at different levels to decision support and experienced partnership approaches in the context of research projects or institutional decision support. Role of scientists in the process is however not trivial to define and operationalize. Several pitfalls can occur that scientists may have experienced through partnership projects or in the expert assessments done for authorities. A workshop was organized from 15 to 17 January 2018 as part of the ScipaDe ... |

| There are two ways of assessing the costs of environmental degradation: as the costs associated with the loss of benefits resulting from the degradation of natural capital, and as the maintenance costs required to compensate for the actual or potential degradation of natural capital. The first of these methods is based on the Total Economic Value (TEV) of benefits forgone because of the depletion of ecosystem services delivered by marine biodiversity. The second method is based on the costs required to maintain a good state of marine biodiversity, one which makes it possible to deliver ecosystem services. This paper gives an illustration of this second approach. It details how these maintenance costs have been calculated in the initial assessment of the... |

| Ecosystem resilience is the capacity of ecosystems to tolerate disorders without collapsing into different circumstances qualitatively controlled by a different set of processes. A robust ecosystem is one that can withstand shocks and rebuild itself when necessary. This study aims to identify the value of use-based economy and non-use value of current economy; calculating the total economic value of mangrove resources; and provide suggestions and recommendations based on observations in Timbulsloko, Sayung, Demak. The method used is economic valuation with total economic value technique. The sampling technique used non-probability and purposive sampling method. The results showed that the direct use value of mangroves was utilized by fisherman, fish pond... |

| Developed at the end of the last century, oyster farming and mussel farming are the two main components of shellfish farming in France. Recent advances in hatchery and farming techniques of species such as the clam and scallop open up new growth potential for new farming. This is already the case for the former, because clam farming produced 560 tonnes of clams in 1987. The volume of shellfish production, 170,000 tonnes in 1987, puts France among the foremost producing countries out of a world production of shellfish greater than 1.5 million tonnes. In value, this production represents, depending on the year, 15 to 20 percent of the total production of the French marine fishing and farming sector. This is therefore an extremely important business, which... |

| Un constat s'impose : l'explosion de l'activité crevettière tropicale en Asie, n'a pas laissé entrevoir de développement durable en un même lieu géographique au delà d'un horizon de dix ans. L'objectif est donc de définir les moyens et les actions à mettre en oeuvre en vue d'un développement durable du secteur. Une initiation du personnel Indonésien au traitement d'enquête, à la construction et à la gestion d'une base de données étant une condition sine qua none au suivi du projet. |

| Trout and salmon market is one of the major markets for fish in France. The domestic production covers the demand for trout and it is very stable (30.000 tons) after a rapid expansion during the early eighties. With the rapid expansion of the world production, the price for salmon has been steadily decreasing since 1986. The French market for salmon depends completely on imports. The quantity imported increases more rapidly than the drop of the price. Salmon import is the main cause for the deficit of the trade of seaproducts in France. Salmon production is not likely to expand significantly during the coming years. The troutproduction sector seems to be at the point where the commercial benefits (quality control, trade scale economies, promotion...) may... |

| Coastal fisheries and marine cultures developed under strong biological, economical and social constraints. Among others are limitation of space and resources, limited availibility of capital, hardship of work,... Industrial, urbanistic and touristic development add to these constraints in coastal areas. Coherent scheme for coastal fisheries management, capture and culture, is of an urgent need. In renewable resources and environnement economics, depletion and pollution resulting from common ownership have been the core of the theory about fisheries management. The chronology of Japanese coastal fisheries management system shows a different approach. In law and decision making, social and economic consequences of conflictual uses and of their regulation... |

| This short paper presents the approach which has been implemented in France for estimating the costs of ecosystem degradation in the context of the Marine Strategy Framework Directive (MSFD). Among the possible approaches, forgone benefits assessment or maintenance costs assessment, France decided to use the latter. The paper contains an introduction, a section which explains how to choose an economic approach coherent with the MSFD rationale, a section which exposes the methodology developed for implementing the approach, and a section on the main results. |

| Dans le pénible périple du développement de l'aquaculture nouvelle en Europe, les pays de l'Europe du Sud apparaissent comme des concurrents sérieux. Les conditions naturelles offertes par leur localisation et le soutien actif de la CEE leur donnent des avantages certains pour développer la plupart des productions techniquement maîtrisées, ou en voie de l'être. Parmi ceux-ci la Grèce occupe une position de choix de par la qualité de ses sites et de par les schémas de financement des investissements permettant d'obtenir jusqu'à 60 % d'aides. Un tour d'horizon de l'état et des difficultés de ce développement permettra de mieux évaluer la menace d'une part, et d'autre part de présenter une approche sectorielle qui dépasse les analyses de faisabilité... |

| Known for the presence of its fleet on all the oceans of the globe and its position as world leader in terms of production (12,739,000 tonnes in 1988), Japan also has one of the largest trade balance deficits of seafood. Consumption of fish, a principal source of animal proteins in the Japanese diet, takes on many and sometimes indirect forms with fish- or fishmeal-based farming. |

| Le très long terme, pour l'économie, la sociologie, le droit et les sciences politiques relève de la réflexion séculaire ou pluriséculaire. Il est donc au-delà de la prévision, il ne peut guère relever que de la prospective et de la futurologie. Imaginons la question posée sous la révolution! Or les évolutions démographiques et technologiques ont-été plus rapides au cours des cinquante dernières années que lors, cl-as-deux siècles passés. Par contre, les représentations que les disciplines invoquées se font de la nature et de la société se sont étonnamment peu modifiées, sauf sur un point fondamental: la propriété privée et la maximisation du profit sont devenus le référent quasi-unique de toute réflexion. Soit comme repère intangible, pour les... |

| During the 80s, aquafarming saw the development of new lines of production alongside older sectors of shellfish farming and trout farming that have also seen significant changes. Aid from the Commission of European Communities, along with national aid, has played an important role in the formation of this new aquafarming landscape. At the request of the Commission and under the aegis of the European Association of Fisheries Economists (EAFE), this report presents the current state and future prospects of growth of the main marine and continental aquafarming lines on the one hand, and evaluates the role of this community aid on the other. These experimental or developmental lines, as well as those that can benefit from community aid are not addressed in... |
