Acclimatation du clam (Venus mercenaria L.) en Bretagne ArchiMer
Marteil, Louis.
Large quantities of clams (Venus mercenaria L.) from the U.S.A. have been introduced in Brittany since 1930. Stopped in 1940, their importation started again in 1954. These shellfishes, designed to be immediately sold for eating, only stayed for a short period of time in the ponds and farms of the Belon, Pénerf and Etel rivers, or in the Gulf of Morbihan, where they were stocked. However, some individuals managed to escape the fisheries and stayed buried for years where they had been sown. Lambert (1949) reported how some twenty year-old clams were found on a farm on the Etel River. In some ponds of the Gulf of Morbihan and the Pénerf river, one can still find clams which have been stocked there before 1940: their size is huge and reaches 10 to 14 cm, and...

Création d'un banc d'Ostrea edulis ArchiMer
Marteil, Louis.
Depuis 1945, nous avons entrepris en Bretagne la reconstitution des bancs naturels d'Ostrea edulis depuis longtemps disparus ou fortement appauvris. Cette oeuvre a été réalisée d'abord dans les centres de captage du littoral atlantique; elle a été étendue ultérieurement aux côtes de la Manche, de Brest à Cancale, et sur les côtes de Vendée, en baie de Noirmoutier. Les travaux sont réalisés par des organismes professionnels, des sociétés ou des personnes privées suivant qu'il s'agit de terrains voués à la pêche ou à la culture. A l'heure actuelle, plus de vingt gisements ont bénéficié de ces mesures.

Environnement et mortalite des huitres plates de la riviere de Belon (1961-1970). Donnees generales ArchiMer
Marteil, Louis.
Before 1960 the normal level of mortality of oysters maintained in beds in the Belon river during the summer was in the region of 15%. During several years in the period 1960-1970 much higher mortalities, up to 70% of the stock, were experienced. The circumstances of these mortalities and the appearance of the oysters themselves indicated that no parasitic disease or physiological deficiency was involved. 2 possible caused for the mortalities have been suggested, pollution or a sudden change in the physico-chemical environment. Although some industrial pollution of the River Belon occurs, This is very slight and the oyster beds most affected have been the ones furthest from the source of pollution. Similarly, the River Aven, which has a common mouth with...

Étude des courants du littoral sud de la Bretagne ArchiMer
Marteil, Louis.
In order to understand better the possible influence of currents on the dispersion of oyster or mussel larvae, we carried out, from 1951 to 1953, a large number of float launches in rivers, bays and roadsteads on the coasts of southern Brittany.

La crépidule (crepidula fornicata L.) en France ArchiMer
Marteil, Louis.
L'introduction de Crepidula fornicata L. en Europe remonte à la fin du siècle dernier mais son implantation en France ne date que d'une vingtaine d'années. On découvre chaque année sa présence dans de nouvelles régions productrices de mollusques comestibles, tandis que l'on constate une augmentation progressive des populations de ce gastéropode dans les secteurs les plus anciennement colonisés. Il nous paraît donc opportun de rappeler aux conchyliculteurs et aux pêcheurs son mode de vie, et de leur faire connaître sa distribution actuelle sur nos côtes avant d'attirer, une fois encore, leur attention sur la nécessité de la combattre.

La maladie des branchies des huitres portugaises des cotes françaises de l'atlantique : données générales sur la maladie des branchies ArchiMer
Marteil, Louis.
In the summer of 1967, an abnormally high mortality rate struck the Portuguese oysters, Crassostrea angulata, of the Marennes and Arcachon sites and, less severely, those of the other farming sectors of the French Atlantic coast. Yet the examinations performed in the preceding months had brought to light the existence of rather deep lesions on the gills and sometimes on the labial palpi of a large number of the species' oysters that were not harbouring any pinnotheres. The successive appearance of the two phenomena led us to attribute the observed mortalities to what we have called, for convenience, "gill disease". The various specialised laboratories of the Institute of Fishing strove to determine the nature of the infection, its distribution in France...

La reproduction de l'huître portugaise (Gryphaea Angulata Lmk) dans les centres de captage de la cote atlantique ArchiMer
Lafuste, J.; Le Dantec, Jean; Marteil, Louis; Trochon, P..
La reproduction des huîtres portugaises a eu lieu en 1955 dans des eaux à température élevée. La récolte du naissain a été dans l'ensemble excellente. Pendant l'été 1956 les températures des eaux côtières demeurèrent anormalement basses. Les émissions de larves furent en général sporadiques, à évolution nulle ou incertaine; l'intensité des fixations observées est essentiellement fonction de la date d'immersion des collecteurs.

La technologie ostréicole ArchiMer

Oyster deposits are currently used as a complementary production source in order to supply oyster farms, and form genitor stocks in the collection areas. Oyster farming uses different practices and methods whose main similarities, differences and characteristics as far as collection, farming and finishing are concerned, are described in the following.

Le captage du naissain d'huîtres portugaises en Vilaine ArchiMer
Marteil, Louis.
A l'embouchure de la Vilaine, rivière située aux confins du Morbihan et de la Loire-Inférieure, s'est développée depuis fort longtemps une industrie mytilicole prospère. La culture de la moule (Mytilis edulis L.) est pratiquée en bouchots sur une centaine d'hectares en aval du petit port de Tréhiguier en Pénestin. La production annuelle de ces parcs dépasse 2.000 tonnes; les produits des moulières naturelles qui bordent la côte servent à l'ensemencement des concessions. A l'intérieur de la rivière; il ne subsiste plus rien des gisements mouliers qui jadis s'étaient établis ça et là, partout où la nature du fond le permettait. Bien que la culture de l'huître portugaise (Gryphea angulata Lk) soit autorisée depuis 1923 sur la rive gauche de la Vilaine,...

Le dragage des huîtres portugaises en gironde ArchiMer
Le Dantec, Jean; Marteil, Louis; Trochon, P..
To sum up, the Gironde River estuary, the main Portuguese oyster production area, is visited each year by a large number of boats which come for a few days to dredge its natural deposits. The gradual increase of their number and of the efficiency of the fishing gear, as well as the fluctuating fishing performance show the need to define the basis of a rational exploitation in order to protect these oyster banks. Based on the data collected from 1956 to 1958 we set up a work schedule for the visitation commission which should meet at the end of winter, and we put figures on the assessment basis that should help this commission to determine the duration and intensity of each year's exploitation.

Les bancs naturels et la reproduction de l'huître plate en Morbihan ArchiMer
Marteil, Louis.
Natural beds of Ostrea edulis, long since decimated, began to repopulate the rivers of the Morbihan "département" in 1943. In 1955, I reported results acquired during the 1943-1954 period and highlighted the effects the repopulation seemed to have on oyster spat collection. It is thus useful to explore to what extent the population has grown and the influence that the renewed population success has had on the European flat oyster in bays and rivers.

Les mortalites d'huitres en 1970 ArchiMer
Marteil, Louis.
From the studies conducted in 1968 and 1969, it becomes clear that there was a relationship between the flat oyster mortalities that occurred during the summer in the Belon and Merrien rivers and the appearance of a hydrological phenomenon primarily characterised by an overhang of abnormally cold water. Because the events recorded in July 1970 confirm the data already acquired, we will summarise the observations made on that occasion by MARIN, PAULMIER OR GRAS.

Les problèmes de la production d'huîtres plates en Bretagne ArchiMer
Marteil, Louis.
Le développement de la production de jeunes huîtres plates est unanimement souhaité par les Pouvoirs publics et les organismes représentatifs de la Conchyliculture. On en justifie l'opportunité par la nécessité d'approvisionner en quantité suffisante les terrains d'élevage dont la surface, en Bretagne, a plus que triplé entre 1949 et 1964 et dépasse actuellement 5 000 hectares. Les quantités de semences nécessaires sont diversement évaluées : elles devraient atteindre 1 200 à 1 500 tonnes par an selon les uns, 2 000 tonnes selon les autres (1). Or les possibilités actuelles de captage en Morbihan ne semblent pas devoir être supérieures à 1 000 tonnes par année de "bonne production", ce qui représente déjà plus d'un milliard de naissains. Ce chiffre n'est...
