Le complexe «Dinophysis acuminata»: identification des espèces le long des côtes françaises ArchiMer
Lassus, Patrick; Bardouil, Michele.
From seawater samples collected between 1984 and 1989 in 12 French coastal areas, a morphometric study have been realised on Dinophysis genera restricted to "acuminata" like species. Simple morphological criterias are given as suitable for discrimination of four dominant species occurring during toxic episodes in shellfish farms (Diarrheic Shellfish Poisoning): Dinophysis c-closed-integral. sacculus, D. c-closed-integral. acuminata, Dinophysis sp. and D. c-closed-integral. norvegica. This last species cannot be included in the "acuminata complex" and produces temporary blooms along southern Brittany coasts. Pending a more precise diagnosis it is recommended to clarify the relationship between toxin composition and each species previously described.

Le renouvellement des flottilles en France de 1945 à 1983 : discours, contexte et réalisations ArchiMer
Meuriot, Eric.
This study recounts the policies on fishing fleet renewal in France from 1945 to 1983. The views held by sector professionals and the public authorities on the role of fleet renewal in fisheries economy are put into context in terms of stock abundance, access to fishing grounds, the state of the market, etc. The consequences of the lack of consistent guidelines for distributing the resources between competing fleets, foreign or national, are presented. The limits of the stances held on technical "progress" and "reasonable" management of resources are discussed. Other, complementary lines of research to undertake are proposed as a conclusion. Many tables and figures illustrate the text.

L'elevage de la palourde, programme national de recherche sur la maladie de l'anneau brun ArchiMer
Flassch, Jean-pierre; Barret, Jean; Mazurie, Joseph; Maes, P; Nicolas, J; Noel, Thierry; Paillard, C; Lepennec, M.
A national program started in 1989 to drive researches on Ruditapes philippinarum brown ring disease correlated with a vibrio called P1. The researches have concerned epidemiological surveys on spats and adults, treatment methods, diagnostic techniques, and anatomical and functional studies about the vibrio-clam relations. The transmissions of the disease appeared mainly related to contaminated manila clam seeds, with secondary horizontal propagation. The brown ring formation appeared to be caused by a periostracum deterioration. Taking into account some of these results, an adapted cultural technique including special care of seeds and decreased densities was proposed to the farmers.

Coppejans, E..
The author describes the biotopes seen during 55 diving-sessions (1977-'81) between 30 m and 75 m depth in the Bay of Calvi (Corsica). The phycological epiflora is shortly characterized and a list of the collected species is given, it contains 194 taxa of which 26 Chlorophyceae, 40 Phaeophyceae and 128 Rhodophyceae; 4 species are new to Corsica. This species-list is compared with those of Molinier (dredging, Cap Corse) and of Giaccone (diving, Tyrrhenean Sea).

Les activités de production - conchyliculture ArchiMer
Deschamps, Gerard; Miossec, Dominique; Pannier, Thierry; Huet, Jerome; Lorance, Pascal.
These studies of halieutic ecology produced at the request of Electricité de France by the French Institute of Research for Exploitation of the Sea in the Normand Breton Gulf must constitute one of the elements making it possible to come to a conclusion or not on the feasibility of the tidal power plant construction project; these studies have three parts: The first part discusses halieutic zooplankton. In the first place, the main species that constitute the exploitable living resources are considered, observed from the first stages of their life, in the egg or at different larval stages preceding the juvenile state. Also of interest are certain holoplanktonic groups. The whole of these observations establishes the status of zooplanktonic populations...

Les associations bacteries-matiere particulaire en milieu pelagique cotier: Exemples de variations spatiales et temporelles ArchiMer
Jacq, Estelle; Prieur, D.
Studies concerning the respective role of free-living and particle-bound bacteria in pelagic ecosystems, sometimes gave opposite results. The comparative distribution of these bacterial patterns was studied in two sites of Brittany. In the Bay of Brest, a shallow and semi-enclosed area, the bacterial communities were dominated by the free-living forms, except during the phytoplankton bloom, which was accompanied by a clear increase of the particle-bound forms. Off the west coasts of Brittany, the Ushant front separates stratified water masses from mixed water masses. The distribution of particle-bound bacteria fluctuated according to the structure of the water masses and in mixed waters, was related to particulate matter from different origins. Results...

Les dinophycées pélagiques et benthiques du Golfe de Gascogne sud de la Bretagne à Arcachon ArchiMer
Paulmier, Gerard.
Les microphytes planctoniques et benthiques du Golfe de Gascogne sont relativement diversifiés. Cette diversification est probablement en rapport avec la situation hydrologique particulière de cette région enrichie par des mélanges de masses d'eau de diverses origines et par des apports continentaux importants. Dans ce contexte, les dinophycées sont nombreuses et variées et occupent toutes les niches écologiques. 230 taxons ont été répertoriés. Quelques espèces sont connues pour provoquer périodiquement des colorations de la mer "eaux rouges" et quelques-unes sont maintenant redoutées pour leur toxicité.

Les huîtres des côtes françaises Ostrea edulis et Gryphaea angulata ArchiMer
Lambert, Louis.
Les bancs d'huîtres plates Ostrea edulis formaient jadis un cordon ininterrompu sur toutes les côtes de France. Quelques chiffres donneront une idée des quantités d'huîtres pêchées jadis sur les côtes françaises. A la fin du XVIII ème siècle et au début du XIV ème, les pêcheurs enlevaient des seuls bancs de Cancale et Granville au minimum cent millions d'huîtres par ans; leurs bateaux pêchaient du 1er Septembre au 1er Avril sans discontinuer. La destruction du naissain et des petites huîtres par les dragues très lourdes que l'on employait alors était plus grand encore. L'exportation, de 1772 à 1775, atteignit le chiffre de 293 millions. En 1775, notamment, 234 bateaux normands et 104 anglias emportaient de la baie de Cancale 95 millions d'huîtres.

Les marees vertes: Premier bilan concernant les essais de valorisation ArchiMer
Brault, D; Briand, X; Golven, P.
Seasonal green algal blooms (Ulva lactuca ) are observed along Brittany coasts and estuaries. The example of Lannion Bay during 1982 is exposed, with the causes and the consequences. After treatment, these seaweeds can be used for energy production (methanization and composting) and animal feeding (laying hens).

Les pêches professionnelles dans les estuaires de la Loire et de l'Adour ArchiMer
Guerault, Daniel; Desaunay, Yves; Beillois, Pierre; Prouzet, Patrick; Martinet, Jean-pierre; Cuende, François - Xavier.
The exploitation of amphihaline species by marine and freshwater commercial fishermen in the Loire estuary in 1989, and by marine commercial fishermen in the Adour estuary from 1985-1991 is described in this study. This fishery employs 320 fishermen and represents a commercial value of 38 million FF. This is mainly due to the exploitation of glass eel, especially in the Loire River, the landings of which have decreased alarmingly. In the Adour River, the diversity of the exploited species and the total commercial value of drift gillnet catches - on the average 43% - in this fishery are high. The landings of migratory salmonid species are high and they may attain 25% of the total commercial value. This study emphasizes the uniqueness, the socio-economic...

Les récifs artificiels - Etat des connaissances et recommandations ArchiMer
Gerard, Andre; Thouard, Emmanuel; Veron, Gerard; Denis, Jacques; Thebaud, Olivier.
The "Artificial reefs" and "Repopulating" issues have been tackled by the Ifremer for a number of years without reaching a clear cut point of view, mainly for lack of socio-economic elements necessary to a rigorous analysis of these devices and practices. During a mission in Japan in January 2006, some Japanese experts, have presented to the head of the Ifremer a few examples of realisations related to these fields and conducted in their country. The head of the Ifremer realised the scope of such devices in Japan and expressed the wish to see an in-depth study carried out over there. In this purpose, the International Relationship Department organised and co-financed the three-month stay in Japan of a student from the University of Montpellier III, Sylvain...
