1.This report presents the results of a field study conducted in the ECASA test site nOS in the Pertuis Breton, France. The site is located on the Atlantic West coasts. It is open to the bay of Biscay, but is slightly protected against westerly winds. The bay has been exploited by intertidal mussels culture for centuries. 2. Within the bay, mussels (Mytilus edulis) are cultivated either by the traditional pole technique, around the bay or on longlines in the centre of the bay. The area occupied by these longline s represents 250 ha, and the resulting annual production is 1 000 tonnes of mussels. The average depth at mid tide is of 13.8 m. The sediment is sandy, with a small fraction of mud. 3. The site is subject to several regular monitoring through the...

La crépidule (Crepidula fornicata), mollusque gastéropode de la famille des Calyptraeidés, originaire de la côte atlantique d'Amérique du nord, a été introduite accidentellement sur le littoral français en plusieurs étapes (Blanchard, 1995, 1997). La plus importante d'entre elles, au début des années 70, est liée à l'importation massive de l'huître japonaise (Crassostrea gigas), en remplacement de l'huître portugaise (Crassostrea angulata) décimée par une épizootie. Cette espèce opportuniste a notamment proliféré au voisinage des principaux bassins ostréicoles de la Manche et de l'Atlantique. C'est en particulier le cas des zones conchylicoles infralittorales du golfe normano-breton où des évaluations de stocks font état de plusieurs centaines de milliers...

Spatio-temporal differentiation in the population structure of Hydrobia ulvae on an intertidal mudflat (Marennes-Oleron Bay, France)
Provedor de dados: 5
Autores: Haubois, Anne-gaelle; Guarini, Jean-marc; Richard, Pierre; Blanchard, Gerard; Sauriau, Pierre-guy.
Spatio-temporal changes in density, breeding cycle, growth and population structure of Hydrobia ulvae (Gastropoda: Prosobranchia) were studied by monthly sampling of a wide bare mudflat in Marennes-Oleron Bay. Four stations, located along a cross-shore transect and characterized by different geomorphological structures, were investigated from March 2000 to February 2001. Hydrobia ulvae was mainly distributed in the upper half part of the mudflat and no individuals were found in the lower part. The breeding cycle extended from March to December and showed two annual peaks, in spring and in autumn. Three cohorts were recruited during the year and showed high growth rates during summer; the parameters of the von Bertalanffy model describing the growth curves...

Spatio-temporal structure of the epipelic diatom assemblage from an intertidal mudflat in Marennes-Oleron Bay, France
Provedor de dados: 5
Autores: Haubois, Anne-gaelle; Sylvestre, F; Guarini, Jean-marc; Richard, Pierre; Blanchard, G.
Spatio-temporal changes in taxonomic composition and structure of an epipelic diatom assemblage from an intertidal mudflat on the French Atlantic coast was studied over an annual cycle along a cross-shore transect. The assemblage structure was described by estimating both relative abundance and contribution to biovolume of each species. Results showed that the assemblage was numerically dominated by small-sized species (mean relative abundance of 91%). Large species, however, significantly contributed to the total biovolume (mean contribution to biovolume of 49%). A factorial correspondence analysis indicated that the epipelic assemblage was relatively homogeneous along the cross-shore transect but emphasized the seasonal succession of diatom species. In...
