Etude expérimentale de la prédation de la palourde japonaise, Ruditapes philippinarum, par la dorade royale, Sparus aurata, et le baliste, Balistes capriscus ArchiMer
Robert, René; Parra, René.
Depuis 1988, d'importantes mortalités de palourdes japonaises Ruditapes philippinarum ont été enregistrées, sur de nombreux élevages, dans le bassin d'Arcachon. Pour expliquer celles-ci, l'hypothèse d'une prédation par la dorade royale Sparus aurata et par le baliste Balistes capriscus était avancée. Afin de la vérifier, une étude expérimentale de la prédation de la palourde par ces deux poissons a été réalisée en laboratoire. Si les relations taille prédateurs-taille proies sont plus marquées chez le baliste, les deux espèces sont particulièrement voraces, puisqu'elles s'avéraient capables de consommer, en 24 h, 500 petits naissains et 350 jeunes palourdes de 25 mm de longueur, 50 % à 70 % des proies étant consommés au cours des 6 premières heures....

Growth and mortality of the European oyster Ostrea edulis in the Bay of Arcachon (France) ArchiMer
Robert, René; Borel, Michel; Pichot, Yves; Trut, Gilles.
A study of the growth and mortality of the European oyster Ostrea edulis , including the effects of Marteilia refringens and Bonamia ostreae , was carried out in three oceanic areas in the Bay of Arcachon from May 1989 to February 1991. One-year-old spat, free from disease were used for the trials. Six months after beginning the trials, Marteilia refringens had severely infested the cultures. Although Bonamia ostreae was found during the first year, the rate of infestation was low. In the second year bonamiasis increased and high mortality (> 60%) occurred in Ostrea edulis populations. Although the growth of the oysters was good, their condition index was generally poor. Moreover, shell perforations by Polydora sp. were observed. The influence of...

Le Danger des Traitements par le Sulfate de Cuivre en Zone Conchylicole : Toxicite vis-a-vis des Oeufs et des Jeunes Larves de Crassostrea gigas. ArchiMer
His, Edouard; Robert, René.
Oyster farmers use a solution of copper sulphate to kill competitors and seaweeds on their oyster grounds. Experiments describe the influence of this product on embryos and D larvae of Crassostrea gigas. Concentrations above 25 g/l are toxic for embryos, and above 100 g/l disturb growth of more resistant D larvae. However this product is less toxic than copper chloride.

L'unite d'ecophysiologie et de molysmologie larvaire des bivalves d'interet commercial du laboratoire I.S.T.P.M. d'Arcachon. ArchiMer
Robert, René; His, Edouard; Maurer, Danièle.
An experimental hatchery for bivalves and the different techniques used in Arcachon are described: sea water treatment, phytoplankton culture, conditionning of oysters for spawning and larval culture. This experimental unit has been organised to study the reasons why natural reproduction is disturbed in the bay. The quality of the oysters and the sea water was analysed to ascertain their capacity to acquire normal oyster development. Also, the influence of different micropollutants which may disturb the environment were studied. Observations during larval stage at various concentrations of chemicals include: percentages of fertilized eggs; percentage of D larvae former; percentages of normal and surviving larvae, larval growth, establishing growth curves...

Observation on the feeding behaviour of Crassostrea gigas larvae in the bay of Arcachon (France) ArchiMer
Robert, René; His, Edouard.
Crassostrea gigas Iarvae were collected in the bay of Arcachon in July 1985, 1986 and 1987. Larval samples were collected daily at high tide, during at least the first 12 days of pelagie lire and every hour during 1 day and night cycle, 6 days after spawming. Epifluoreseence microscopy was used for detecting ingestion and digestion of nanoplankton and thin sections were made to try to determine the algal species ingested. The first algal uptake occurred 48 hours after fertilization and different stages or digestion were noted from the 3rd day. No relationship between ingestion or digestion and the age of the viligers was observed. There was no difference in the feeding activity du ring day and night. Because the nutrition index was high (70%) the feeding...

Observations sur le phytoplancton du bassin d'Arcachon en période estivale. Rôle potentiel dans la nutrition des larves de Crasssostrea gigas ArchiMer
Maurer, Danièle; His, Edouard; Robert, René.
Des observations sur le phytoplancton du bassin d'Arcachon pendant l'été 1982, montrent une dominance du nanoplancton jusqu'à la fin août, succédant à une floraison micro-planctonique printanière. Ce nanoplancton présente des caractéristiques qui le rendent susceptible d'avoir servi à l'alimentation des larves de Crasssostrea ggias qui se sont très bien développées dans la baie au cours de cette saison de reproduction.
