A bioeconomic analysis of the impact of decommissioning programs: Application to a limited-entry french scallop fishery ArchiMer
Guyader, Olivier; Daures, Fabienne; Fifas, Spyros.
The objective of this paper is to assess the benefits and costs of decommissioning policies aimed at reducing fleet capacity through premiums offered by the public authority to fishermen to scrap their vessels. A case study, the limited entry scallop fishery of the Saint Brieuc Bay, France, is used to con- sider the problem of excess capacity and to model the bioeconomic consequences of disinvestment behavior. Special attention is paid to the assessment of fishermen's willingness to leave the fishery and to the implementation of public policy in terms of budget level and premiums offered to the fishermen. Spreadsheet simulations show that the impact of decommissioning programs is positive in terms of net surplus, even in the case of increasing technical...

A Case Study of Technological Switching and Technological Lock-In in the French Fisheries Sector: Why is Sustainable Change so Difficult? ArchiMer
Le Floc'H, Pascal; Daures, Fabienne; Guyader, Olivier; Wilson, James.
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...

A comparison of economic performance in the fisheries sector: A short- and long-term perspective ArchiMer
Le Floc'H, P.; Daures, Fabienne; Brigaudeau, Cecile; Bihel, J..
Indicators of the economic performance of fishing vessels are frequently computed in various countries. In this paper, we use different types of information to assess capital value and the economic performance of fishing vessels. On the one hand, field surveys provide technical and financial information on the main components of fishing capital. On the other hand, book values are given in bookkeeping databases. Both sources of information on fishing capital are used for the same set of vessels, namely the commercial fishing fleet of the French region of Brittany. Based on these two sources, measures of economic performance can be produced for the short term using gross surplus; and for the long term including the cost of capital. The measures of...

A fleet-metier based approach of the small scale fishing activity in the French West Indies ArchiMer
Guyader, Olivier; Reynal, Lionel; Demaneche, Sebastien; Berthou, Patrick; Daures, Fabienne.
The development of the ecosystemic approach for fisheries supposes to improve integrated analysis of fisheries by considering the biological as well as the socio-economic dimensions of the exploitation. A prerequisite for integrated analysis is the improvement in the knowledge of fleets structure, fleet evolution and allocation of fishing effort in the different fisheries. However, small scale fisheries are often characterized by a lack of knowledge on the vessel fishing activity. This paper first presents a data collection methodology recently applied in the French West (Guadeloupe and Martinique) for the follow up of the whole vessel population. Based on a statistical analysis of these data sets, the paper develops a fleet-metier matrix giving the...

BESTCLIM. Buccin Espèce SenTinelle pour le CLIMat ArchiMer
Hegron – Mace, Laurence; Legrand, Véronique; Kellner, Kristell; Grangere, Karine; Cochard, Marie-laure; Vigneau, Joel; Daures, Fabienne.
La Baie de Granville représente la première région française et européenne de pêche du buccin. Même si cette ressource génère une activité économique importante à l’échelle de la Normandie avec un volume de 8 800 tonnes, 16.82 millions € en 2014 (source SIH), elle reste néanmoins vulnérable. BESTCLIM a pour objectif de 1) Développer la connaissance du cycle de vie du buccin, 2) Evaluer l’activité de la pêcherie et l’état du stock de buccin en Ouest Cotentin avec des méthodes appropriées, 3) Caractériser les aspects socio-économiques de la pêcherie. L’élévation de la température de l’eau impacte la reproduction du buccin en retardant le déclenchement de la gamétogenèse des mâles. Elle a pour effet de réduire de manière importante l’émission de pontes par...

Capacity and scale inefficiency: Application of data envelopment analysis in the case of the french seaweed fleet ArchiMer
Guyader, Olivier; Daures, Fabienne.
Data Envelopment Analysis (DEA) models are applied to the main French seaweed fleet to examine capacity output, capacity utilization, and scale inefficiency. Coastal seaweed vessels target only one output - kelp - with the same gear but with different input level combinations. The fishery is seasonal and subject mainly to input regulations, especially a one trip per day regulation implemented in 1987. The consequence was a decline in total observed output and a fall in capacity output and efficient output. Only the largest vessels and a few small vessels harvesting without this regulatory constraint operate at the optimal scale. The question of a change in regulation, especially a shift to an individual quota system, is raised.

Capacity management, not stock status or economics, drives fleet dynamics in the Bay of Biscay ecosystem on a decadal time scale ArchiMer
Rochet, Marie-joelle; Daures, Fabienne; Trenkel, Verena.
This paper introduces a semiqualitative approach to analyse the joint dynamics of fleets and stocks in a multispecies, multifleet fishery. We ask whether changes in fleets affect resource dynamics and whether trends in resource influence fleet dynamics more than external drivers do. External drivers include vessel buyback, fuel price, and fish prices, as well as environmental fluctuations. Resource status is measured by abundance and length metrics; fleet capacity is measured by total horse power, and economic metrics such as profitability and earnings are examined as well. A maximum likelihood approach is used to identify the combined metric trends with the largest support in the data. The approach is applied to the French Bay of Biscay fisheries in...

Comparative analysis of production systems in fisheries and aquaculture ArchiMer
Daures, Fabienne; Girard, Sophie; Dieudonné, Eva; Mardle, Simon.
The D3.6 aims to assess the competiveness and sustainability of production systems (PS) for all case studies covered by SUCCESS (Whitefish, Flatfish, Coastal fish and shellfish, Mussels, Salmonids, Seabass & Seabream and Carp). This assessment relies on a number of selected indicators which include indicators of economic performance, economic dependency, social and environmental sustainability indicators. The seven case studies represent a significant part of the EU fisheries and aquaculture production (FAP) as they contributed to 55% of the total EU Seafood production in value (38% in volume) in 2014. Case studies include PS ranging from large production units and/or companies, strongly dependent on inputs availability and extra EU imports (whitefish...

Decommissioning schemes and capacity adjustment: A preliminary analysis of the French experience ArchiMer
Guyader, Olivier; Berthou, Patrick; Daures, Fabienne.
The French decommissioning aims at permanently removing vessels from the fishing fleet according to European Union rules laid down within the Common Fisheries Policy. A system of premiums established by the French government is supposed to give the vessel-owners, the incentives to get rid of their fishing unit. This paper details the rules for the applicants and their evolution and it provides a preliminary analysis of the impact of these schemes over the 1991-2001 period. Special attention is paid to the characteristics of decommissioned vessels and of their owners. The problem of windfall gains of these policies is approached, and a first assessment is given. The consequences in terms of capacity adjustment are discussed according to the Multi Annual...

Ensuring representative economic data: survey data-collection methods in France for implementing the Common Fisheries Policy ArchiMer
Van Iseghem, Sylvie; Quillerou, Emmanuelle; Brigaudeau, Cecile; Macher, Claire; Guyader, Olivier; Daures, Fabienne.
Since 2001, Ifremer has implemented an economic data collection programme (EDCP) within the Data Collection Framework of the EU. It aims to obtain economic data from a sample of vessels representative of the entire French fishing fleet. This paper presents the strategies used for vessel sampling selection in the French EDCP and its implementation over several consecutive years. The approach is illustrated by the sampling plan for the fleet in the North Sea Channel Atlantic region. We show that the EDCP allows precise economic indicators such as gross revenue or fuel costs to be estimated for the whole fishing fleet, including small vessels (< 10 m), and consequently, it facilitates sound scientific advice regarding the Common Fisheries Policy. The...
