| Ten years after the start of the European Data Collection Framework the availability of cost indicators for assessing the economic status of fisheries or bio-economic modelling is still deficient. Moreover, economic time series are difficult to maintain due to fishermen weariness and sample coverage is often insufficient. To overcome these problems, the paper builds predictive models per operational cost category (fuel, landing, other variable, fixed, salary and total) for the French Bay of Biscay fleet. The cost models had good fit and stressed the key role of gear and vessel size (length mostly) for explaining fishing costs. They suggested that only a small list of variables was needed to predict costs (days-at-sea, total revenue, vessel age, length and... |

| This paper investigates some economic consequences of creating a marine reserve on both fishing and ecotourism, when the range of controllability of fishing effort is limited and the impact of the reserve on ecosystem is considered. The issue is illustrated by the example of creating a no-take zone in part of a region where fishing is managed through a limited entry license system, and which is inhabited by two interacting stocks: a stock of prey (fish) and a stock of predators (seals). While the former is targeted by commercial fishing, the latter is not subject to harvest but is a potential basis for a commercial non-extractive activity (seal watching). Analysis is conducted with the help of a bioeconomic model combining the features of marine reserve... |

| Blue marlin is fished in the French Antilles around Fish Aggregating Devices (FADs). This fishery commenced in late 1985 and the fishing fleet reached its full potential in the second half of the 2000s. A fisheries information system (SIH), implemented from 2008, enables good estimation of catches and effort around FADs. The data on catch estimates of blue marlin and associated fishing effort are presented herein, as well as the methods used to assess them. From these and a survey of fishing masters, it is possible to reconstitute, year by year, the fishing fleet working around FADs in the French Antilles and to reconstitute a historical series of blue marlin landing. |

| A survey of past and existing management measures applied to different fisheries in European Western Waters is analyzed as a typology of co-management between governments and stakeholders. Faced with increasing constraints on accessing fish stocks, management measures have evolved toward fishing rights individualization, limited access and various other specific measures. Restrictions on access have changed fishermen’s behaviour in several significant ways. A comparative analysis, based on qualitative data collected through interviews and focus groups, is developed for fisheries from the following European countries: France, Ireland, Spain and the United Kingdom. Past and existing individual harvesting rights in the four countries are reviewed and compared. |

| In most fisheries worldwide, crew are paid through different shared remuneration systems rather than a fixed wage. In shared remuneration systems, wages can significantly increase when the economic performance of vessels improve, and consequently provide incentives to workers. However, in recent years, mainly due to high overexploitation levels that lead to reduced productivity and consequently lower salaries shared remuneration systems have lost their attractiveness. Different remuneration systems applied in fisheries world-wide are described and analyzed comparatively. Results explain how crew wages and rent distribution outcomes vary between the different remuneration systems depending on the state of exploitation of the resource. |

| The main objective of this report is to establish well-founded proposals for the design, implementation and responsible management of the comprehensive product “fishing tourism or pesca-toursim”, taking into account its diversity and adaptability to environmental, socioeconomic and cultural impacts. The project seek ed to establish a comprehensive intelligent management system to promote sustainable relationships among the different stakeholders for activities developed in coastal ecosystems. This product of “Fishing-Tourism” may be closely related to protected areas, as it may be intended to show not only the fishing culture but also the natural heritage of the areas involved. This report emphasizes the relevance of stakeholders’ participation... |

| 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... |

| Many sectors such as the fishery show classic examples of technological lock-in and path dependence, even though some economists might predict smooth switching toward technologies that are more cost effective and sustainable. We use ideas from the evolutionary economics and public choice literatures to explain why trajectories of technological change, especially in fisheries, may not be smooth at all, but rather punctuated. The interest of technological change and switching behavior for fisheries economists and managers stems from the fact that control of effective effort, often necessary for sustainable management of the resource, remains a central management problem for that sector worldwide, even in developed countries. However, various policies put in... |

| Moored fish aggregating devices (MFADs) are used by small-scale fishers to access fish species difficult to harvest in large numbers. In the case of Guadeloupe (Caribbean area), the use of MFADs has increased considerably and this is causing congestion in these fishing areas and creating conflict between fishers. The aim of this article is to understand how informal fishing territories around the La Desirade Island were established and examine these territories through the lens of economic defendability theory. Results of semistructured interviews show that MFAD fishers display territoriality along MFAD tract lines forming quasi-privatized areas. Territoriality in this article is based on the following factors: the type of targeted resources, the cost of... |

| Dans le cadre du projet de DCP collectifs, l’Association des pêcheurs du Sud Basse-Terre (APBST) a demandé à l’Ifremer d’organiser un suivi de l’activité de pêche sur ces dispositifs ancrés, afin de contribuer à l’évaluation de l’impact de l’implantation de ce parc de DCP. L’Ifremer étant responsable du projet pilote de Système d’Informations Halieutiques (SIH) en Guadeloupe sur la période 2007-2008, le suivi DCP collectifs s’insère dans ce dispositif avec un renforcement des moyens de collecte de données sur la zone d’étude. 12 dispositifs de concentration de poissons (DCP) collectifs conçus pour répondre aux exigences du développement durable ont été immergés par l’APSBT au large de Basse-Terre (Guadeloupe) en janvier et février 2008. Cette opération qui... |
