| Introduction: During each summer season, the IFREMER laboratory of Arcachon monitors, within the framework of the agreement with the Arcachon- Aquitaine Shellfish Farming Regional Section (SRC), the reproduction of cup oysters in the Arcachon basin. This monitoring has as its goal to furnish oyster farmers with the information needed to implement spat catches: - dates and size of egg clutches, - larvae development rate, - presence in the environment of more evolved stages (close to fixation). Reproduction was monitored between mid-June and mid-September, plankton was fished four times per week at the various sites representative of the basin. Oyster larvae at various stages are enumerated there. At the end of the reproductive season (September to... |

| In 1983, the parasitism of Mytilus edulis L. by Proctoeces maculatus (Loose, 1901) Odhner, 1911 (Trematoda, Digenea, Fellodistomatidae), was recorded for the first time by the authors from mussels farming on stakes (Western Cotentin). After analysing the distribution of the prevalence on the shore and bibliographical data, it was suggested that this parasite must follow a biological cycle that had never been observed on the French coasts and that the most probable host of eggs producer - adult or progenetic metacercaria - would not be a fish but the Prosobranch Gasteropod Nucella lapillus . This was confirmed in 1987. This discovery enabled the authors to support a campaign of eradication of this mussels predatory mollusc. In 1990, the parasitism has... |

| 31 Cardiidae species have been collected in Ambon, Indonesia by the Rumphius Biohistorical Expedition, comprising circa 40% of the known species of this family from the Indonesian archipelago. Seven of these could be traced to the figures given by Rumphius (1705) and an additional two, taking into account some reservations about the identity of Rumphius' depicted shells. This implies that all but one of Rumphius' species, viz. Tridacna (Tridacna) gigas (Linnaeus, 1758), have been reencountered by the present expedition. The expedition has yielded the first Indonesian published records of two species: Fulvia (Laevifulvia) lineonotata Vidal, 1994 and Acrosterigma dianthinum (Melvill & Standen, 1899). For the latter this implies a considerable range... |

| The black-lip pearl oyster Pinctada margaritifera lives and reproduces with high performance in most of Tuamotu Lagoons. Technics to collect spats, to culture juveniles and to operate oysters were quickly found and applicated. Nevertheless, the sudden rise of this activity has been correlated with an anarchic development. For instance, large occupation of areas in the lagoons, cultivation of numerous oysters in confined areas, lack of knowledge on the basis culture technics in many farms. In 1985, mass mortalities have appeared in some lagoons and 50 to 80% of cultured stock died. Some investigations have been done but no explanation was found. In 1988, the mortalities are still very high. An analysis of cooperative production results from 1979 to 1988... |

| Of the 29 species of Pectinidae here recorded from South Africa and Mozambique, ca. 76% have Indo-West Pacific origins, 17% are of Mediterranean-West African origin and ca. 7% are probably of Southern Ocean origin. New species: Mirapecten tuberosus, Veprichlamys africana. New subspecies: Aequipecten commutatus peripheralis. New synonyms: Chlamys liltvedi Wagner, 1984 = Laevichlamys lemniscata(Reeve, 1853). Genus Karnekampia Wagner, 1988 = Pseudamussium Mörch, 1853, Somalipecten Waller, 1996 = Mirapecten Dall, Bartsch & Rehder, 1938. Perapecten Wagner, 1985, and Lindapecten Petuch, 1995 = Aequipecten Fischer, 1886.

| The identity of the subgenera Isocrassina Chavan, 1950, Laevastarte Hinsch, 1952, and Ashtarotha Dall, 1903, of the genus Astarte Sowerby, 1816 in the family Astartidae (Mollusca, Bivalvia) is discussed. Isocrassina has been widely used for Pliocene species in the North Sea Basin. Here it is demonstrated, that this is based on a redefinition of this subgenus, which excludes its type-species. As the North Sea species differ considerably from the type-species of Isocrassina in aspects of ornament and details of the hinge, it is concluded that they should be placed in the genus Laevastarte. A slightly modified definition of Isocrassina and Laevastarte is given and both are raised to genus level. The morphological basis for Ashtarotha is quite weak and it is... |

| Background The Quality Assurance and Laboratory Standards Committee of the American Society for Veterinary Clinical Pathology and the guidelines of the Clinical and Laboratory Standards Institute provide a framework for establishing reference intervals of physiological parameters in reputedly healthy individuals, humans, and terrestrial animals, respectively. This framework was applied for the first time to the Pacific cupped oyster, Crassostrea gigas. Reference intervals (RIs) would, first, be of interest for research purposes, including pathophysiology studies. RI determination is the first step before considering the use of RIs for field applications by farmers and marine shellfish health services. Objectives The purpose of this study was to propose... |

| Nursery rearing of bivalve molluscs, as the intermediate step between the controlled production of larvae in commercial hatcheries and the growout in the wild, is a practice which is receiving more and more attention in mollusc farming. The purpose of nursery rearing of bivalves is to culture cultchless spat of a few millimeters in size, up to 1-2 cm, in a minimum of time, in densities as high as possible, and at minimal costs and risks. In the last decade various technologies for nursery culturing, indoors as well as outdoors, have been developed at different places, ranging from suspended culture in the open sea to controlled onshore culture in upwelling cylinders. This paper reviews the different systems developed until now, with special emphasis on one... |

| In order to estimate energetic relationship, microphytic and benthic bivalve levels of a shallow (1.5 m), sandy ecosystem near Marseille (Gulf of Fos, Southern France) were sampled monthly during 1.5 year, in two sites differing by their wave exposure. In the sheltered area, the bivalve Ruditapes decussatus was the dominant species, while another bivalve, Donax trunculus , was found in the open, wave exposed site. Chlorophyll a and primary production of the phytoplankton and the microphytobenthos, as well as population dynamic, growth and biochemical composition of bivalves (lipids, proteins and carbohydrates) were monitored. |
