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.

Évolution pléistocène de la Seine fluviatile préservée en Baie de Seine ArchiMer
Benabdellouahed, Massinissa; Dugue, Olivier; Tessier, Bernadette; Thinon, Isabelle; Guennoc, Pol.
New high-resolution seismic data complemented with bedrock samples allowed us to propose a revised geological map of the Bay of Seine and to better define the control by the geological substrate on the morphogenesis and evolution of the Seine River during Pleistocene times. The new data confirm previous works. The Bay of Seine can be divided into two geological parts: a Mesozoic monocline domain occupying most of the bay and a syncline domain, mostly Tertiary, in the north, at the transition with the Central English Channel area. The highlighting of Eocene synsedimentary deformations, marked by sliding blocks in the syncline domain, is one of the most original inputs of this new study in the Bay of Seine that underlines the significant role of the...

Gisement d'huitres plates de Saint Valery en Caux à Saint Aubin ArchiMer
Deschamps, Gerard; Schlaich, Ivan.
Formerly, along the Caux shoreline there were large oyster banks or natural beds of flat oysters. Overexploitation led to downgrading of this bed in 1927. At the beginning of the month of September 1986, the Fécamp local committee of fisheries requested to make three tides over the former bed with the goal of finding new resources. Because these three tides were fruitful, IFREMER was asked to prospect on this oyster bank in order to know whether it could once again be classified.

Le chalutage à perche ArchiMer
Jean-pierre, Dugauquier.
This study on pole trawling was done with the goal of giving some clarification about a theoretically prohibited fishing technique that is little used in France. However, fishermen from some countries routinely practice pole trawling authorised at the European level, which poses a few problems from the point of view of French regulations, and it is on an exempt basis that this technique is used by some boats in Brittany and Normandy, but the only large fleet that is practising pole trawling intensively by using boat booms is based in Dunkerque's harbour. It is the reason for which we studied the Dunkerque fleet's activity and operation; the technical aspect of the trawl was described at length. The contentious situation brought on by the practise of this...

Modelling the influence of environmental factors on the physiological status of the Pacific oyster Crassostrea gigas in an estuarine embayment; The Baie des Veys (France) ArchiMer
Grangere, Karine; Menesguen, Alain; Lefebvre, Sébastien; Bacher, Cedric; Pouvreau, Stephane.
It is well known that temporal changes in bivalve body mass are strongly correlated with temporal variations in water temperature and food supply. In order to study the influence of the year-to-year variability of environmental factors on oyster growth, we coupled a biogeochemical sub-model, which simulates trophic resources of oysters (i.e. phytoplankton biomass via chlorophyll a), and an ecophysiological sub-model, which simulates growth and reproduction (i.e. gametogenesis and spawning), using mechanistic bases. The biogeochemical sub-model successfully simulated phytoplankton dynamics using river nutrient inputs and meteorological factors as forcing functions. Adequate simulation of oyster growth dynamics requires a relevant food quantifier compatible...

On the interest of using field primary production data to calibrate phytoplankton rate processes in ecosystem models ArchiMer
Grangere, Karine; Lefebvre, Sebastien; Menesguen, Alain; Jouenne, Fabien.
In many ecosystem models based on empirical formulations, parameters generally are calibrated in order to achieve the best fit between measured and simulated chlorophyll a standing stocks. An accurate calibration of rate processes as primary production rarely is taken into account. In this paper, we test the usefulness of calibration of phytoplankton photosynthetic processes in an ecosystem model using field primary production data. We used 18 months of photosynthetic process data from the Baie des Veys ecosystem (Normandy, France). Five empirical formulations of photosynthesis-irradiance curve models amongst the most widely used were tested. In each formulation, the variability of photosynthetic parameters (i.e. the light-saturated rate of photosynthesis...

Opmerkelijke vondst: tropische tapijtschelp aan de Normandische kust Naturalis
Meij, S.E.T. van der.
During a week of fieldwork along the coast of Normandy, France, the author found a tropical carpet shell on the beach of Granville. Field guides could not properly identify the shell and therefore it was compared with the collections of the National Museum of Natural History in Leiden and the Zoological Museum of Amsterdam. This comparison resulted in four possible identifications - Ruditapes variegatus, Venerupis aurea, Ruditapes philippinarum and Ruditapes semidecussatus. However, the specific shell colour pattern does not fully correspond with the pattern of these four species, making identification of the shell difficult. The most likely identification seems to be Ruditapes semidecussatus. In France carpet shells are cultured for consumption. The...

Organochlorinated contaminants in decapod crustaceans from the coasts of Brittany and Normandy (France) ArchiMer
Bodin, Nathalie; Abarnou, Alain; Le Guellec, Anne-marie; Loizeau, Veronique; Philippon, Xavier.
The contamination and distribution of organ ochlorinated compounds were considered in three crustacean species (edible crab, Cancer pagurus; spider crab, Maja brachydactyla; velvet swimming crab, Necora puber) from five sites along the coasts of Brittany and Normandy (Western and North-Western France). PCBs (16 single congeners), pp'-DDE and HCB were measured in hepatopancreas, gonads and muscle: in all, 175 samples were analysed. The spider crab was the only species found in the five sampling sites, thus enabling comparison between areas. Specimens from Antifer were much more contaminated (Sigma(16)PCBs in hepatopancreas = 2000-4000 ng g(-1) dry weight) than those from other sites (50-1000 ng g(-1) d.w.). Among all the three species, the spider crab...

ReMoNor : Mise en place et premier bilan du Reseau Mollusque de NORmandie (1998-1999) ArchiMer
Ropert, Michel; Blin, J.l.; Cornette, Florence; Pacary, S; Pien, S; Leganeur, E; Kopp, Joel; Richard, O.
Since 1998, a growth and quality monitoring study of reared molluscs has been developped as part of a close collaboration between the Shellfish Research Laboratory of Normandy (IFREMER Port-en-Bessin, Calvados) and the SMEL (Syndicat Mixte d'Expansion du Littoral) Experimental Centre (Blainville, Manche). REMONOR (REseau MOllusque de NORmandie) is based on the experience gained through the national monitoring network REMORA, which protocol has been entirely applied. Adults and spat of Pacific oysters Crassostrea gigas were placed in 13 stations all along the oysters rearing areas of Normandy. These oysters had the same origin and history (i.e. age and weight) until they were dispatched on the 13 stations. 4 essential criteria were used to monitor rearing...

ReMoNor : Résultats 2000 ArchiMer
Cornette, Florence; Blin, J.l.; Pacary, S; Pien, S; Le Gagneur, Eric; Kopp, Joel; Richard, O.
At the end of its third year, the regional network for monitoring REMONOR, confirms the particularities of oyster from Normandy in matter of growth and quality. Results from 2 000 are globally very close of those from 1998. Mortality of adults reached 14% and juvenile 6% which represent a low death rate. For this year the most blow area is the Baie des Veys with 31% death rate at Géfosse. Observed growth this year had been weaker than the past two years despite the spring and automnal growth. At spring, the higher recorded growth rate on the West coast with 0.42% (regional average : 0.29%). This seasonal trend seems more and more obvious every year. Regarding the classification of the special oysters, despite the change of the standard, the Baie des Veys...

The regional network REMONOR showed 2001's characteristics of growth and quality of oysters (Crassostrea gigas) in the three rearing areas of Normandy. Compared to year 2000, two additional stations along the East Coast have been settled. The summer adults mortalities have been registered between 0 % and 25 %. The average for all the rearing areas reached 6 %. Highest rates have been noticed in the Baie des Veys and the East Coast. The juvenile's mortality occurred during the same season, in summer. This year 2001 is included in lower growth years in all Normandy. This year, the West Coast growth rate appeared to be quit unusual. For the first time growth rates were in the average in the northern area that usually shows very bad performance. We can...

Simonne, Charlotte; Pien, S; Hugonnet, Virginie; Le Gagneur, Eric; Ropert, Michel; Kopp, Joel; Richard, O.
The national REMORA network is targeted on the studies of growth, flesh quality and mortality of a sample of cupped oyster Crassostrea gigasdistributed on 9 stations along the coast of Normandy. As a better precision is needed for regional purpose, 7 new stations have been added. A total number of 16 stations is now sampled from Chausey to Meuvaines. Weak rates of mortality have been noticed in 2002 on both adults (7%) and spat (6 %). These rates are the weakest ever seen. The mortality rates in the Baie des veys were less than 10 %. This rearing area shows usually a much higher mortality level. Growth rates were noticed weaker than usual. They slowly decline from 1999. From Mach to December, the growth rate of adults has been computed to 0,21 %/day (for a...

Simonne, Charlotte; Pien, S.; Hugonnet, Virginie; Le Gagneur, Eric; Ropert, Michel; Kopp, Joel; Richard, O..
The network named REMONOR (REseau MOllusqueNORmandie) aims to assess mortality, growth and tissue quality of the Pacific oyster, Crassostrea gigas, cultivated in Normandy over an annual cycle. This local network relies on the same material and methods as the national one named REMORA (REseau Mollusques Ressources Aquacoles). The study was carried out in 17 sites, which were distributed in the four basins where oyster rearing occurs in Normandy (West and East coast of Cotentin, Baie des Veys and Meuvaines). In 2003, a new site was added, which was located in the area of Ver-Sur-Mer (Calvados). The results obtained in 2003 showed a low annual mortality for adults (8%) as well as for juveniles (10%). Growth was also low for the two age classes of oyster...

Mary, Charlotte; Pien, S; Blin, J.l.; Ropert, Michel.
The regional monitoring network REMONOR, relying on the experience of IFREMER's REMORA national network, each year assesses the mortality, growth and quality for two age classes ("adults" = 2 years and "juveniles" = 1 year) of cup oysters, distributed among various farm sites in the main oyster farming sectors of Lower Normandy. This network, led in collaboration by LERN (Environment Resources Laboratory) and SMEL (Coastline Installations Public-Private Entity), this year welcomes a new farm site in Veules les Roses, in Seine Maritime (76), bringing to 18 the total number of monitored sites. For operational reasons, a reduced monitoring protocol was conducted in 2005 on this last farm site, which will not take on the network's standardised protocol until...
