Bonamia ostreae (Pichot et Coll., 1979) parasite de l'huître plate : comparaison de deux méthodes de diagnostic ArchiMer
Bachere, Evelyne; Durand, Jean-louis; Tige, Gilbert.
The parasite, Bonamia ostreae, was diagnosed in several South Brittany flat oyster's samples, from gills tissues's prints, stained in May-Grunwald-Giemsa and from corresponding digestive glands sections. The comparaison of results shows quantitative differences relating to the infested oyster's rate, and qualitative differences relating to the early stages of infestation. Gill's print technic seems more intersting for the only Bonamia ostreae diagnosis.

Efficacité d'un outil de politique structurelle dans le secteur des pêches : le plan Mellick ArchiMer
Durand, Jean-louis; Gueguen, Jacques; Catanzano, Joseph.
In order to comply with the requirements of the second Multiannual Guidance Plan concerning the fishing fleets in the EEC Member Countries, the French Secretary of State for the sea has implemented a decommissionning scheme in March 1991. To facilitate the withdrawal of an overall engine power representing 100000 kW, subsidies have been attributed to owners scaping their boat of selling it outside the EEC or for a purpose other than fishing. In parallel social measures were set to help the resignation or the retirement of skippers. In March 1992 applications concerning 975 vessels representing about 84 300 kW had been presented. Brittany accounts for 48.5 % of the boats and 43 % of the withdrawn power whereas the mediterranean ports represent only 9 % of...

Etude d'une gestion optimale des pecheries de langoustines et de poissons demersaux en mer Celtique ArchiMer
Laurec, Alain; Charuau, Anatole; Perodou, Jean-bernard; Nedelec, Daniel; Biseau, Alain; Durand, Jean-louis; Rivoalen, Jean-jacques; Dupouy, Herve; Le Louarn, G.; Leroux, L..
The general study, scheduled from 1984 to 1986, aims at providing a judgement about the fisheries in the Celtic Sea. This area has been chosen because it is frequented by EEC vessels with, for the time being, a large majority of French vessels. Activities there are easier to monitor than anywhere else as coastal fisheries are little developed in the area. The final product will consist of a certain number of hypotheses about the planning strategies that could be implemented in the Celtic Sea. The main idea is, firstly, to conduct analytical studies, stock by stock, in order then, to synthesize them into a model integrating the interactions between fleets in relation to their target species. A bio-economical model, deriving from the latter, will enable the...

La flottille et les engins de la peche artisanale dans le Mor Braz ArchiMer
Durand, Jean-louis.
This document produces the small scale fishing fleet, along the french coast between Quiberon and Le Croisic in 1983. It submits a calculation of the fleet movments during a year and a analysis of the antagonisms between different fishing gears usings, It, also, suggests a breakdown the fleet into 7 types.

Les pêcheries démersales et benthiques de l'ouest de l'Ecosse (sous-zone CIEM VI) Modélisation des interactions techniques. ArchiMer
Durand, Jean-louis.
The aim of this study is to consider the 8ub area VI fishery as a mixed fishery and to try to apply on it methods which allow interactions analysis between fish stocks and different kinds of boats. For that purpose, after gathering all information about this area, three main directions are followed. First of all, it was necessary to build up a synopsis about the ten most important stocks fished in sub area VI, then to propose a splitting of the fleet into "metier" with different exploitation patterns and, lastly to give a complete description of one of the most important fishing grounds off western Europe.

L'exploitation des ressources halieutiques dans le Mor Braz ArchiMer
Durand, Jean-louis.
Introduction: Marine organism mortality in the Vilaine bay during July-August 1982, consecutive Dynophysis growth since that date prohibiting shellfish commercialisation, repetitious conflicts among sea professionals are the reflection of a fragile ecosystem and current instability of halieutic resources exploitation in Mor Braz . Becoming aware of this fragility the Ministère de la Mer (Ministry of the Sea) initiated the creation of the Commission Quadripartite (Quadripartite Commission) in charge of the Hydrobiologic Protection and Alieutic Development of the Quiberon-Vilaine bay, bringing together administrative and scientific professionals. Right from the start, among the missions entrusted to the Commission, the will to study the halieutic future of...

Mise au point d'une méthode d'estimation du recrutement en huîtres plates (Ostrea edulis L.) sur coques de moules en suspension ArchiMer
Martin, Anne-genevieve; Durand, Jean-louis; Carbonnier, N.; Le Bec, Claude; Langlade, Aime; Claude, Serge.
A new process of collecting fIat oyster spat in deep water, based on the use of suspended mussel shell, was perfected between 1978 and 1982. The technique has contributed the continued breeding of the species in Quiberon bay (Brittany ) , in spite of the presence of Bonamia ostreae. In order to quantify the number of spat recruited by this technique each year, a method of estimation was tested during the summer 1985. This paper describes the sampling strategy and the results.

Programme d Orientation Pluriannuel concernant une action commune de restructuration, de modernisation et de développement du secteur de la peche ArchiMer
Minet, Jean-pierre; Biseau, Alain; Charuau, Anatole; Dupouy, Herve; Durand, Jean-louis; Perodou, Jean-bernard.
Answering a need of the Office of Regional Marine Affairs of Brittany, the "fisheries" laboratory of the Ifremer in Lorient provides synthesis elements about the status of the stocks of the main species exploited in the Bay of Biscay, Celtic Sea and Western Ireland in 1983. It provides information about the fishing capacity according to the different jobs done and compares two fleets from South-Brittany: Lorient and Concarneau. This report will have to be completed by the laboratories of Roscoff for activities in North-Brittany and of la Rochelle for activities in the Bay of Biscay.

Questions sur la dynamique de l'exploitation halieutique ArchiMer
Laloe, Francis; Rey, Hélène; Durand, Jean-louis.
Whether what is at stake is land-use management and stabilising the economy of the shoreline areas for a good number of developed countries or involvement in food self-sufficiency, contributing to the balance of payments and stabilising employment for developing countries, in every instance, the economic and/or political importance of fisheries management as a business sector is far from being marginal in most of the countries concerned. Thus, from the moment the question of the inexhaustibility of the resources was posed, the desire to manage them manifested itself by the emergence of social demand, peculiarly at around the same time as research, due to the involvement of the researchers in the decision-making bodies of land-use and business management...

Utilisation de données concentrées au niveau des criées pour l'évaluation de la production des navires de pêche artisanale côtière ArchiMer
Gondeaux, Evelyne; Durand, Jean-louis; Flores, Domingo.
L'évaluation des quantités débarquées en pêche artisanale a toujours constitué un problème important. L'élaboration d'une base de données fiable améliorerait grandement l'appréhension de ce secteur économique en grande partie informel. Ce document est une contribution à la mise au point d'une méthode d'estimation des débarquements des navires de petite pêche. L'utilisation de données concentrées au niveau des criées à été privilégiée. Ce choix s'explique par deux raisons. D'une part il est ainsi possible de valoriser une quantité non négligeable des données archivées, et de faire un bilan de l'acquis. D'autre part, la méthode proposée permet de limiter l'utilisation de stratégies d'échantillonnage coûteuses aux fractions de la flottille qui n'utilisent...
