A Fish Discarding Model Including Sorting Behaviour

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...

Biological Invasion Control in a Coastal Fishery: A Bioeconomic Analysis of the Bay of Saint-Brieuc Scallop Fishery (France)

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...

Comparing bookkeeping and field survey methods for assessing fishing fleets economic performance. A case study of Brittany fishing fleets (France)

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...

A Preliminary Analysis of Long-Term Changes in the Value of Landings by French Fishing Fleets Operating in the North-East Atlantic

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....

Estimating Capital Value and Depreciation of Fishing Fleets: Application to French Fisheries

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...

Exploring fisheries dynamics according to different quota governance mechanisms: application to the Bay of Biscay sole fishery

Creator:: Bellanger, Manuel, Merzereaud, Mathieu, Guyader, Olivier, and Macher, Claire
Abstract:: Integrating governance mechanisms into bio-economic modeling tools is a key challenge for the assessment of fisheries management plans. Impact assessments are carried out without considering real management options and institutional context. Only fishing mortality changes and their impact on fish stocks are considered. The Bay of Biscay sole fishery offers...

Self-Imposed Catch Shares by French Producers Organizations

Creator:: Guyader, Olivier, Metz, Sébastien, Macher, Claire, Merzereaud, Mathieu, Daurès, Fabienne, and Le Floch, Pascal
Abstract:: Since 2006, French quotas are shared out into annual catch entitlements per producer organizations (PO) according a stable allocation key. On this basis, PO’s have imposed catch shares to their own members but allocation and management rules are heterogeneous between PO’s. The objective of the paper is i) to assess...

Empirical Analysis of Fishing Fleet Dynamics: Entry, Stay and Exit Choices in Selected EU Fisheries

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...

Explaining Short-Term Choice Through Random Utility Models

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...

An Analysis of Changing Fishing Units Using Field Surveys: Case Studies from the EU

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...
