Voyages sur les côtes de France ArchiMer
Burat, Amédée.
Les voyages et la villégiature sur les bords de la mer sont passés dans nos mœurs ; c'est un nouveau besoin, non seulement pour ceux qui veulent étudier, mais pour le nombre bien plus grand de ceux qui veulent voir. Celte attraction est d'ailleurs motivée par des causes multiples . La vue de la mer est la source d'impressions les plus diverses ; son aspect varie suivant la lumière qui en dessine les horizons, suivant les vents qui en mouvementent la surface , suivant le flot ou le jusant des marées dont les vagues représentent en quelque sorte la vie de la mer et celle de la navigation.

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.

L'huître et l'ostréiculture ArchiMer
Trochon, Pierre.
L'huître appartient à l'embranchement des mollusques, classe des pélécypodes ou lamellibranches, ordre de monomyaires, famille des ostréidés. Les multiples espèces, vivant actuellement dans le monde, il y en a une centaine environ, différent en particulier par la forme variable de leur coquille et par quelques détails de leur organisation interne. Les récentes études des coquilles larvaires, présentant dans leur charnière crénelée des différences remarquables, on permis de déterminer trois genres dans la famille des ostréidés : le genre Ostrea, le genre Gryphaea et le genre Pycnodonta. Sur les côtes françaises, deux espèces sont rencontrées et font l'objet de culture. Ce sont : Ostrea edulis, l'huître plate, et Gryphaea angulata, l'huître portugaise. Le...

La diatomee Navicula ostrearia Bory en baie de Bourgneuf ArchiMer
Robert, Jean-michel.
Previously, Navicula ostrearia B. has been described only from the Marennes-Oleron district of the Atlantic coast of France. However, this pennate diatom is also present In the Bay of Bourgneuf where breeding of green-gilled oysters were recognized in sea basins called oyster ponds. A short description of observations made with the optical microscope precedes description of high magnification examination of the frustule made with the scanning electron microscope. This combination of techniques shows a polymorphism between the external and internal surfaces of diatom valves.

Croissance des moules de bouchots dans la baie de l'Aiguillon (premières observations) ArchiMer
Dardignac, Marie-jose; Feuillet, Michelle.
Le tiers environ des bouchots concédés en France se trouve situé entre La Tranche/Mer en Vendée et Marsilly en Charente Maritime (Fig. 1). On peut distinguer, de part et d'autre de la Sèvre Niortaise, deux secteurs qui diffèrent par la nature de leur sol et, à marée montante, par l'origine des eaux de flot. Au sud de la Sèvre, la sédimentation résulte d'apports en provenance de l'Ile de Ré mais seuls les sables fins et les vases arrivent sur le littoral d'Esnandes-Marsilly où ils se déposent (LORIN, 1970). Au flot, ce secteur reçoit les eaux du Pertuis d'Antioche qui pénètrent par le courreau de la Pallice. Au nord de la rivière, en revanche, la côte vendéenne est constituée de sables moyens et grossiers ; ceux-ci se déplacent le long du littoral et...

Nouvelles observations sur la croissance des moules de bouchots dans la Baie de l'Aiguillon ArchiMer
Dardignac, Marie-jose; Feuillet, Michelle.
Une étude destinée à rechercher les raisons de la différence de croissance des moules au nord et au sud de la Sèvre Niortaise a été entreprise en 1971 par le laboratoire conchylicole de LA ROCHELLE. Les résultats des premières observations ont fait l'objet d'une communication au C. I . E.M. (Dardignac et Feuillet , 1974) ; rappelons les brièvement a} entre Octobre 1971 et Juin 1972, les températures , les salinités et les poids de matériel en suspension ont été analogues au nord et au sud de la Sèvre Niortaise mais la nature des particules en suspension s'est révélée différente: elle était à dominance sableuse au nord, vaseuse au sud; b) au cours de la même période nous n'avons pas observé,entre le nord et le sud de la rivière, de différence significative...

Développement de la conchyliculture et de l'aquaculture importance pour l'aménagement du littoral ArchiMer
Le Dantec, Jean.
In a document from the General Secretariat of the Merchant Navy (P. 3 - MJ - June 1976), it is written: The coast is a rare asset, limited in essence as it is not interchangeable. Moreover, it is coveted and used by numerous users, sometimes aggressive or very powerful, who often take up the areas that are the richest from a biological point of view. This reality is at the origin of a number of land occupancy issues, all the more when a rational or enhancive preliminary choice has not been made. It can also lead to damages or pollutions, the coastal area being more exposed as rivers carry all the effluents which flow into them from their source to the ocean". Witnessing this competition, it appears that marine cultures need to be considered as very...

Etude hydrobiologique du bassin de Marennes-Oleron. Un exemple: la secheresse de l'ete 1976. ArchiMer
Heral, Maurice; Berthome, Jean-paul; Razet, Daniel; Garnier, Jacqueline.
Consequences of drought during the summer of 1976 are related. Principal component analysis allowed the division of the area into 5 main districts, each of them with distinctive hydrological and phytoplanktonic characteristics. The rivers Charente and Seudre are particularly eutrophic and carry great quantities of nitrates, phosphates and silicates. Eutrophic evaluation of the river Seudre is studied, as well as oyster mortalities that resulted. Reproduction and settlement of spat oysters are related to the hydrology of each district.

Infections rickettsiennes chez les mollusques bivalves des côtes françaises ArchiMer
Comps, Michel.
Des microorganismes de type rickettsien ont été observés dans les cellules secrétrices de l'épithélium digestif de différents coquillages des côtes françaises. Chez les huîtres Crassostrea gigas et Ostrea edulis et chez Donax trunculus, les germes sont de forme coccoide ; la réplication s'effectue par division binaire. Leurs caractéristiques permettent de les ranger parmi les Rickettsiales. Des rickettsies avec cycle intracellulaire ont été trouvées chez C. angulata et chez les pélécypodes Tapes decussatus et Scrobicularia piperata. Ces procaryotes montrent un cycle complexe de développement avec des corps élémentaires, intermédiaires et initiaux. Ce cycle est semblable à celui des Rickettsiela ou des Chlamydiales.

Reproduction de la langoustine, Nephrops norvegicus dans la region sud Bretagne ArchiMer
Morizur, Yvon.
The size and age at sexual maturity of the lobsters was determined by secondary sexual characteristics (1) morphological criteria such as length of P1 protopodite, size of the abdomen, and the presence or absence of ovarian hairs in the female; and (2) functional criteria such as the presence of spermatophores in the female and development of the ovaries. A study of fecundity was carried out after maturation of the ovaries and at the end of incubation. The number of eggs lost during incubation was estimated at 45%. The contribution of different age classes to the global fecundity of the stock was simulated on a model of fecundity by recruits.

Note préliminaire sur la mytiliculture dans la région Nord/Pas-de-Calais ArchiMer
Lamolet, J.; Morell, M..
Actuellement, les principaux centres mytilicoles français se trouvent sur le littoral du Cotentin, en Baie du Mont St-Michel, dans le sud de la Bretagne, en Charente et dans l'étang de Thau ; les mollusques y sont cultivés le plus souvent sur bouchots, mais parfois aussi en suspension ou à plat. Cette production est néanmoins très insuffisante ; depuis 1976 par exemple, la France a importé (principalement des Pays-Bas), selon les années, entre 28 et 46% des moules vendues à la consommation : 26 230 T en 1976, 34 510 T en 1977 et 23 600 T en 1979. Jusqu'à présent, le littoral boulonnais ne permet de commercialiser que de faibles tonnages.

Production de Saumon Atlantique (Salmo salar L.) Juveniles et Adultes sur un Ruisseau Pepiniere de Bretagne Nord (France) a Partir d'une Souche Irlandaise. ArchiMer
Prouzet, Patrick; Gaignon, Jean-louis.
An extensive restocking experiment has been undertaken in 1977 on a tributary of Elorn river in the framework of an Atlantic salmon management program of this river of northern Brittany. The results gathered during this experiment permitted the analysis of S. salar production during the juvenile and adult stages from immersion of unfed fry of Irish origin in small nursery streams. The annual production during the first year represented 72% of the total production of two years of growth. Adult runs into the nursery stream were observed between mid-November and mid-December. These runs were initiated by high increases of flow rates of the nursery stream. The whole of the adult population is constituted by late grilses whose female. Their rate of return was...

Répartition géographique et structure de population de Crepidula fornicata Linné dans le bassin de Marennes-Oléron en 1981 et 1982 ArchiMer
Deslous-paoli, Jean-marc; Masse, Henri.
Hundred and ten samplings were made in the bay of Marennes Oleron, during the summer 1981. They allow to localize the hight loads of Crepidula fornicata in the middle of the bay (along the mud-bank of Charret and in the courante d'Oleron°. In this two Points, we value the dry biomass at about 2,3 kg/m2 on the mud-bank of Charret and at 1,1 kg/m2 in the courante d'Oleron. The weight present on this two banks (about 550 000 m2) is approximatively 700 tons of slipper limpets. The mean growth rate is 20, 19, 17 and 12 mm respectively on the 1"-, 2n ,3rd and 4th year with a very important variability since the first year. 74,5 %of the individuals form the main chains (mean of 6 slipper limpets) attached on shells of dead slipper limpets.

Dinoflagelles toxiques sur les cotes francaises pendant l'ete 1983. Manifestations de Dinophysis acuminata sur le littoral normand. ArchiMer
Paulmier, Gerard; Joly, Jean-pierre.
Numerous cases of food poisoning were observed in South Normandy during the summer 1983 and attributed to shellfish consumption. At the same time a dinoflagellate Dinophysis acuminata was found in the Bay of Seine and in north Normandy where high concentrations induced "red waters". The observation of the stomach contents of the mussels showed that this Dinophysis was one of the main constituents of the alimentary bolus. The toxicity of type DSP, determined by the mouse-test, is more or less correlated with the abundance coefficient of D. acuminata . Its space distribution also seems connected to the tidal movements.

La conchyliculture en Méditerranée française ArchiMer
Raimbault, René.
Until now, French Mediterranean shellfish culture was only carried out at relatively sheltered sites: some salted lagoons in Languedoc-Roussillon and Corsica and in the roadsted of Toulon The shellfish culture area of the Thau lagoon spreads out over about 1,200 hectares, that of Leucate over 140 hectares; in Corsica, shellfish farming is carried out on small rafts distributed among the different lagoons (around 80 in Diana and 50 in Urbino). In the roadsted of Toulon, most of the farms are about to close down. According to official figures, the Mediterranean production amounts to about 10,000 tonnes. In reality, the Thau lagoon production alone amounts to, at least, double this tonnage (HAMON et TOURNIER, 1981). It corresponds to at least 90 % of the...
