Creator:: Boncoeur, Jean, Daures, Fabienne, Guyader, Olivier, Martin, Annaick, le Floc'h, Pascal, and Thebaud, Olivier
Abstract:: This paper compares two methods for collecting data concerning professional fishing fleets economic performance : use of preexisting bookkeeping databases and ad hoc field surveys of fishers. Each method has its pros and cons and, for practical reasons, it may be necessary to make use of both. Such a feature...

Creator:: Le Floc'h, Pascal, Daures, Fabienne, Guyader, Olivier, Thébaud, Olivier, and Boncoeur, Jean
Abstract:: Indicators of the economic performance of fishing vessels are frequently computed in many countries. Usually, measures of economic performance are based on the return on capital invested. However, several measures of capital value exist, according to the economic information available. In this paper, we use different types of information to...

Creator:: Daures, Fabienne, Bihel, Julien, Guyader, Olivier, Le Floc'h, Pascal, Roudaut, Nolwenn, Brigaudeau, Cécile, Thebaud, Olivier, and Jezequel, Michele
Abstract:: While the need to solve problems of overcapitalization and excess investment in fisheries is now broadly admitted, very little information exists on the level of capitalization and the structure of capital invested in the fishing sector. This paper presents the first results of a research program aiming at assessing the...

Creator:: Macher, Claire, Guyader, Olivier, and Boncoeur, Jean
Abstract:: This paper proposes a formal analysis of the discarding issue including the sorting labour costs. Empirical evidences from an application to the Nephrops fishery in the Bay of Biscay show that sorting is an important time consuming activity on board and a factor of discarding. However existing literature does not...

Creator:: Mardle, Simon, Thebaud, Olivier, Guyader, Olivier, Hutton, Trevor, Prellezo, Raul, and Travers, Muriel
Abstract:: The decision to enter or exit a fishery can be expected to depend on the anticipated profitability of operating in this fishery, as a function of observed vessel performances in previous years. For a vessel exiting a fishery, there may be several reasons including decommissioning, selling or operating elsewhere. Entry...

Creator:: Prellezo, Raul, Andersen, Bo, Guyader, Olivier, Hutton, Trevor, Marchal, Paul, Mardle, Simon, and Thebaud, Olivier
Abstract:: Fisher behavior can be divided into choices made in the short term (i.e. tactics) and choices made in the long-mid term (i.e. strategies). Random utility modeling (RUM) is well suited for the empirical analysis of these issues. In this paper, RUM is applied to a number of EU fisheries in...

Creator:: Fresard, Marjolaine, Fifas, Spyros, and Guyader, Olivier
Abstract:: This paper deals with the economic impact of an aquatic invasive alien species on a coastal shellfish fishery. A slipper-limpet (Crepidula fornicata ) was accidentally imported some decades ago, has established and is spreading in the bay of Saint-Brieuc (France). This exotic species is acting as a space competitor for...

Creator:: Steinmetz, Fabien, Thebaud, Olivier, Guyader, Olivier, and Blanchard, Fabian
Abstract:: Recent work in the domain of fisheries ecology has shown that major changes are occurring in fish communities exploited by commercial fisheries. Selective fishing pressure on more highly valued components of fish communities, and its indirect effects via trophic interactions, are amongst the key factors proposed to explain these changes....

Creator:: Thebaud, Olivier, Guyader, Olivier, Mardle, Simon, Hutton, Trevor, Le Floc'h, Pascal, Clapes, Juan Pintos, Prellezo, Raul, Steinmetz, Fabien, and Van Oostenbrugge, Hans
Abstract:: The objective of the paper is to briefly present a comparative analysis of trends in the characteristics of selected European fleets, observed over the last fifteen years, as an introduction to three empirical studies of the behavioural determinants of these trends. The analysis presented aims at (i) describing changes observed...

Creator:: Hutton, Trevor, Guyader, Olivier, Prellezo, Raul, Mardle, Simon, and Thebaud, Olivier
Abstract:: Three case studies were included in a study on fishing vessels, most of which use trawl gear in demersal fisheries. The case studies include the French Bay of Biscay bottom-trawlers, the English beam trawlers fishing in the English Channel, Celtic Sea and North Sea, and the Basque trawlers fishing in...
