Although the broad concept of mental models is gaining currency as a way to explore the link between how people think and interact with their world, this concept is limited by a theoretical and practical understanding of how it can be applied in the study of human-environment relationships. Tools and processes are needed to be able to elicit and analyze mental models. Because mental models are not directly observable, it is also important to understand how the application of any tools and processes affects what is measured. Equally important are the needs to be clear on the intent of the elicitation and to design the methods and choose the settings accordingly. Through this special edition, we explore how mental models are elicited using two approaches...

Discolored waters and human diseases by shellfishes were dominant features of summer 1983 in south coast of Brittany. Vilaine Bay, the most damaged area, was successively affected by brown waters in early June, and diarrhetic intoxications by harvested mussels (July and August), just as DPS producing dinoflagellate (D. acuminata ) reached higher water or mussel guts concentrations than years before. Outspreading in the whole south coast of Brittany and possible relation with hydrological or biological parameters are analyzed.

Microflore et anchoitage.
Provedor de dados: 5
Autores: Campello, Francois.
The author studies the microbial phenomena which occur during the maturation of French anchovies, some from the Basque, the others from the Roussillon coast. There are some differences in relation with the origin of the fishes. On a marine agar, the microflora of the Mediterranean ones is almost constant or in a light diminution while that of the Atlantic ones is climbing during 9 weeks before a decline. On an extremely salted agar and in the both origins the archaebacteria are increasing in number during 5 to 6 weeks and diminishing before. The complete ripening is obtained within 16-17 weeks. The limits of the significance of the microbiological analysis are discussed.

No net loss of biodiversity or paper offsets? A critical review of the French no net loss policy
Provedor de dados: 5
Autores: Quetier, Fabien; Regnery, Baptiste; Levrel, Harold.
French regulations concerning the mitigation of development impacts have been progressively strengthened with offsets now required for impacts on forests, wetlands, and protected species, among others. In 2012, following a national consultative process called Grenelle de l’Environnement, legal requirements in terms of monitoring and effective implementation of measures aimed at avoiding, reducing and offsetting impacts were strengthened. This has created strong “demand” for offsets.  The workability of these new requirements has come under scrutiny, not least because of their strong legal and financial implications for developers. In this context, official government guidance on implementing the mitigation hierarchy was published in 2012. Under this...

This study aims to describe the patterns of soft bottom macrozoobenthic richness along French coasts. It is based on a collaborative database developed by the “Réseau des Stations et Observatoires Marins” (RESOMAR). We investigated patterns of species richness in sublittoral soft bottom habitats (EUNIS level 3) at two different spatial scales: 1) seaboards: English Channel, Bay of Biscay and Mediterranean Sea and 2) 0.5° latitudinal and longitudinal grid. Total observed richness, rarefaction curves and three incidence-based richness estimators (Chao2, ICE and Jacknife1) were used to compare soft bottom habitats species richness in each seaboard. Overall, the Mediterranean Sea has the highest richness and despite higher sampling effort, the English Channel...

Bivalves: Indicateurs de pollution microbienne des eaux littorales
Provedor de dados: 5
Autores: Plusquellec, A; Beucher, M; Legal, Y.
Sea water and mussels from a natural site (Concarneau - France) have been compared for fecal contamination by enumeration of their fecal Coliform and fecal Streptococci content. Mussels contain a significant concentration of bacteria, although this concentration differs for the two indicators. Enumeration of fecal Streptococci in bivalves leads to a reduction of the variability observed in sea water. Mussels allow a more efficient assessment of Salmonella in the marine environment than sea water itself.

1. Introduction: network organisation in 1997. The REMORA network - REseau MOIIusques du département Ressources Aquacoles de l'Ifremer - (Ifremer's Aquaculture Resources Department Mollusc Network) has been evaluating, since 1993, hollow oysters' growth (Crassostrea gigas) in major French oyster beds. In order to do so, it has followed up on a yearly basis the growth of a unique oyster batch shared among different stations in the main French raising areas. Releasing takes place in February and picking happens in November or December; intermediary sampling is done in June and September. All operations happen on the same dates for all stations. A national report is published each year. 'Regional' stations are sometimes added to the national network, but they...

Provedor de dados: 5
Autores: Lebec, C; Mazurie, Joseph.
To provide updated information on the growth of Crassostrea gigas in Brittany, experimental stations on 8 sites (culture area) were monitored. Biometric measurements (length, width,...), meat composition (proteins, lipids, carbohydrates...), quality, survival and parasitism were observed after 7 months. A descriptive study by principal components analysis was conducted to find the most significative variables explaining the variability and classifying the sites. Six groups of station can be identified by their respective performances that have been screened in detail. An optimal strategy was discussed to establish a most efficient data network in Brittany. The yearly variations will be checked up and their correlations with environmental factors tested...

La dynamique des pêches côtières du pays bigouden
Provedor de dados: 5
Autores: Charuau, Anatole.
In the beginning, the coastal fleet of the Bigouden region fished by trawling and was completely focused on exploiting lobster and hake. It is a traditional business that expanded between the last war and the 70s, reaching its peak between 1975 and 1980.  The best image to give an idea of this fleet is that of a "bucket waterwheel" endlessly discharging its catch in the four ports of the Guilvinec district. Where there is a seafaring business in Guilvinec, Loctudy and Saint-Guénolé, there is a complementarity that is expressed in two ways: - coastal fishing constitutes a very noticeable and regular supplement to production, since sales happen daily and only bad winter weather causes a relative decrease in the supplement. - coastal fishing gives a...

A comparative analysis of Alexandrium catenella/tamarense blooms in Annaba Bay (Algeria) and Thau lagoon (France); phosphorus limitation as a trigger
Provedor de dados: 5
Autores: Hadjadji, Imene; Frehi, Hocine; Ayada, Lembarek; Abadie, Eric; Collos, Yves.
Environmental conditions ultimately leading to blooms of the toxic dinoflagellate Alexandrium catenella/tamarense were investigated at two Mediterranean sites (Annaba Bay, Algeria and Thau lagoon, France). Three years were examined in details: 1992 (a pre-Alexandrium period), 2002 (a year with the first bloom in Annaba) and 2010 (a year with a major bloom in Annaba). Most conditions were similar, but ammonium concentrations were much higher in Annaba (up to 100 μM) than in Thau (up to 10 μM). First records of A. catenella/tamarense were in 1995 for Thau and 2002 for Annaba, and coincided with soluble reactive phosphorus (SRP) decreasing below a concentration of about 1 μM. No other environmental variable could be related to those blooms. Thus, it is likely...

The "Artificial reefs" and "Repopulating" issues have been tackled by the Ifremer for a number of years without reaching a clear cut point of view, mainly for lack of socio-economic elements necessary to a rigorous analysis of these devices and practices. During a mission in Japan in January 2006, some Japanese experts, have presented to the head of the Ifremer a few examples of realisations related to these fields and conducted in their country. The head of the Ifremer realised the scope of such devices in Japan and expressed the wish to see an in-depth study carried out over there. In this purpose, the International Relationship Department organised and co-financed the three-month stay in Japan of a student from the University of Montpellier III, Sylvain...

Traditional oyster culture in France
Provedor de dados: 5
Autores: Heral, Maurice.
The indigenous oyster of mainland France, the fiat oyster, Ostrea edulis has been part of the human diet for centuries. The Romans collected them and exported them to Rome. Although tanks for holding oysters after harvesting were in use at that time (GreIon 1978) it seems that true culture was not developed along the coast contrary to the records of Pliny the Older. It appears that oysters were already being captured on hoards off the Italian coast. The exploitation of natural stocks continued through the Middle Ages and the Renaissance. However, it was not until the 17th century that oyster culture began, first in the pools of the salt marshes of the Atlantic coast and then in specially managed ponds. Papy (1941) repeats a good description given in 1688...

Factors determining the distribution of foraminiferal assemblages in Port Joinville Harbor (Ile d'Yeu, France): the influence of pollution
Provedor de dados: 5
Autores: Debenay, Jean-pierre; Tsakiridis, Erica; Soulard, René; Grossel, Hubert.
Port Joinville harbor is located on an island. Thus, it receives only a few freshwater inputs, contrary to most of the areas where the influence of pollution on foraminiferal assemblages has been studied. The pollution in the harbor mainly results from the boats, including cleaning, painting and outfall of oil and motor-fuel.A total of 59 sediment samples was collected at three sampling periods (November-December 1997, May 1998 and September 1998). These samplings were supplemented by the study of algal flora and macrobenthos and by the study of water circulation by means of six stations where water was collected every hour during a tide cycle. Contaminants were analyzed in the last series of 17 samples. Total assemblages were used for this study. This...

Innovative flume experiments were conducted in a recirculating straight flume. Zostera noltei meadows were sampled in their natural bed sediments in the field at contrasting stages of their seasonal growth. The aims of this study were: (i) to quantify the combined effects of leaf flexibility and development characteristics of Zostera noltei canopies on their interaction with hydrodynamics; and (ii) to quantify the role of Zostera noltei meadows in suspended sediment trapping and bed sediment resuspension related with changes in hydrodynamic forcing caused by the seasonal development of seagrasses. Velocity within the canopy was significantly damped. The attenuation in velocity ranged from 34 to 87% compared with bare sediments and was associated with a...

The monitoring network IFREMER /REMORA is assessing, on a yearly basis, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year old ; and "adults" = two-years old), distributed among various stations of the main French oyster areas. Samplings are carried out in March, June, September and December. This network is a tool for trend estimations (geographic and chronological, on the national scale) ; it must not be considered as an accurate estimation of professional oyster ongrowings. In 2001, mortality mainly occured in Summer on "adults" in baie des Veys (Normandy) and on juveniles in Cancale and Pénerf (Brittany) and in Fouras and Marennes (Poitou-Charentes). With an average individual weigh of 59 g in December, 2001 has been a...

Organochlorinated contaminants in decapod crustaceans from the coasts of Brittany and Normandy (France)
Provedor de dados: 5
Autores: 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...

Evaluation du risque d'introduction d'espèces indésirables par l'intermédiaire des eaux de ballast des navires - Deuxième partie
Provedor de dados: 5
Autores: Masson, Daniel; Courtois, Olivier; Masson, Nadine; Guesdon, Stephane; Rocher, Gregory; Margat, Sylvie.
L'activité de transport maritime dans les eaux côtières et les ports français nécessite que les navires ballastent ou déballastent pour décharger ou prendre du frêt. L'eau de mer (ou d'estuaire) rejetée à cette occasion a souvent été prise aux escales précédentes dans d'autres parties du monde et peut contenir des organismes vivants néfastes pour la faune, la flore, ou l'activité économique des régions côtières françaises. Il en est de même des eaux françaises prises comme ballast. Certaines espèces peuvent proliférer dans un nouveau milieu où les facteurs de leur régulation n'existent plus et devenir envahissantes (jacinthes d'eau en Floride ou moules zébrées dans les Grands Lacs).  Les plus néfastes sont les bactéries et le phytoplancton toxique....

Autores: Vaillant, Véronique; Jourdan-da Silva, Nathalie; Quilici, Marie-laure; Couturier, Elisabeth; Le Guyader, Soizick; Delmas, Gilles; Le Saux, Jean-claude.
Shellfish filter large volumes of water to meet their nutritional requirements and thus ingest phytoplankton, but also concentrate microorganisms naturally present in water (vibrios, phycotoxins) or of fecal origin (enteric viruses, enterobacteria, protozoan). The analysis of data from systems contributing to the surveillance of foodborne illnesses associated with shellfish consumption and from published outbreak investigations shows that, in France, foodborne illnesses associated with shellfish consumption are mainly of viral origin, mostly due to norovirus followed by hepatitis A virus. The risk linked to phycotoxins appears low and the one related to enterobacteria and vibrios very low. The mandatory notification (MN) of foodborne outbreaks remains the...

Multiscale spatio-temporal variability of sedimentary deposits in the Var turbidite system (North-Western Mediterranean Sea)
Provedor de dados: 5
Autores: Mas, Virginie; Mulder, T.; Dennielou, Bernard; Schmidt, S.; Khripounoff, Alexis; Savoye, Bruno.
The Var turbidite system is a small sandy system located in the Ligurian Basin (Mediterranean Sea). It is active during present sea-level highstand and shows four types of sediment transfer processes: (1) low-density turbidity surges generated by small-scale failures (2) low-magnitude, high-frequency (yearly) hyperpycnal turbid plumes, (3) high-magnitude, less-frequent, hyperpycnal currents and (4) high-magnitude flows generated by large slope failures. These processes have different imprints on the morphology of the system. Inversely, the topography plays a role on the behaviour of these flows. The depositional and erosional architecture of the system has been investigated in detail on the basis of SAR imagery and a set of cores using an interface corer...

Les huîtres des côtes françaises Ostrea edulis et Gryphaea angulata
Provedor de dados: 5
Autores: 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.

Croissance des moules de bouchots dans la baie de l'Aiguillon (premières observations)
Provedor de dados: 5
Autores: 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...

Séquences d'évolution morphodynamique des barres intertidales d'une plage macrotidale : l'exemple d'Omaha beach (Normandie, France)
Provedor de dados: 5
Autores: Stepanian, A; Levoy, F.
The present paper deals with the morphodynamics of intertidal bars on Omaha beach, a macrotidal beach located along the Normandy coastline. During two years (defined here as medium-term time-scale), a monthly topographic monitoring has been conducted on this beach. An analysis of the morphological evolution of the ridge and runnel systems is performed and correlated to the forcing conditions (waves and tide) recorded on the lower foreshore. Our results allow to distinguish some morphodynamical evolution sequences with one stage of accretion and one stage of destruction of the bars. In order to discriminate these two stages, an energetic criterion is used. Accretion stages correspond to long periods of fair weather conditions (significant wave height, H-s...

On the interest of using field primary production data to calibrate phytoplankton rate processes in ecosystem models
Provedor de dados: 5
Autores: 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...

Autores: Briant, Nicolas; Chouvelon, Tiphaine; Martinez, Laura; Brach-papa, Christophe; Chiffoleau, Jean-francois; Savoye, N.; Sonke, J.; Knoery, Joel.
Marine mercury (Hg) concentrations have been monitored in the French coastline for the last half a century using bivalves. The analyses presented in this study concerned 192 samples of bivalves (mussels: Mytilus edulis and Mytilus galloprovincialis and oysters: Crassostrea gigas and Isognomon alatus) from 77 sampling stations along the French coast and in the French Antilles sea. The goals of this study were to assess MeHg levels in various common bivalves from French coastline, and to identify possible geographic, taxonomic or temporal variations of concentrations. We show that the evolution of methylmercury (MeHg) concentrations covary with total mercury (HgT) concentrations. Moreover, in most of the study sites, HgT concentrations have not decreased...

Bilan du suivi de l'exploitation industrielle de la crépidule en Bretagne Nord (baies de Saint-Brieuc et du Mont Saint-Michel) 2002-2005
Provedor de dados: 5
Autores: Blanchard, Michel; Hamon, Dominique.
The slipper-limpet (Crepidula fornicata) is a marine gastropod which causes serious perturbations in shellfish beds, because of spatial spreading and density rising. Along French coasts, in Northern Brittany, two bays are highly colonized : bay of Saint-Brieuc, centre for scallops fishery, and bay of Mont-Saint-Michel, a famous oyster-farming area, with a total limpet stock about 450 000 metric tons. The association AREVAL was founded in 2001 to manage there, an industrial collect of limpets by a succing-dredge, followed ashore by a treatment for calcareous soil improvement. The scientific survey, contracted to IFREMER, included measurements of long andshort-term dredge's effects on grounds and limpet population, and proposals to set up dredging...

New modelling of submarine gravity flows: application to the Nice collapse in 1979.
Provedor de dados: 5
Autores: Hugot, Alexandre; Joseph, Philippe; Savoye, Bruno; Zaleski, Stéphane.
We propose to apply in this note a simple mathematical model for the sedimentation of gravity deposits in deep water. An inverse method has been developed in order to characterize the parameters associated with the submarine flow. This method also provides the initial conditions, which constitute a major uncertainty in geoscience modelling. Application of the inverse method to the 1979 Nice air-port collapse (southern France), constrained by cable breaks and/or deposit thicknesses, leads, for example, to the estimation of the initial volume and/or the physical parameters of the flow (friction coefficient, modified turbulent Schmidt number, etc.). The application of the model to this real case shows that only the simultaneous inversion of dynamic (cable...

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.

Observers were set on board of fishing vessels from North Brittanny ports during one full year (1992-93). This study granted by EC Commission (contract CE/DGXIV-C-1 n° 1992/06) was a first approach for assessing French discards in the western English Channel. It identifies the main species discarded and produces a rough estimate of discard rates and size compositions in each métier targeting fish. The major reasons for variability were explained. Size compositions of catches and discards were provided in order to permit better estimates of the mortality induced by fishing operations. The fixed nets observed were large mesh nets (270 to 360 mm) targeting monkfish and small mesh nets (&lt;200 mm) targeting coastal resources. Netting was found to be more...

La conchyliculture en France : importance économique, aléas et contraintes, axes de recherche privilégiés
Provedor de dados: 5
Autores: Bonnet, Marc; Troadec, Jean-paul.
En France, l'élevage des mollusques est une activité très ancienne dont les premières apparitions empiriques remonteraient au 13ème siècle pour la mytiliculture (origine de la technique du bouchot) et au 17ème siècle pour la culture de l'huître plate (engraissement dans les réservoirs des marais salants de la côte atlantique). Ce n'est cependant qu'à partir du milieu du siècle dernier que cette activité a pris son essor pour suppléer la simple cueillette qui s'exerçait depuis toujours sur les gisements naturels. Cet essor, surtout appréciable à travers l'évolution de l'ostréiculture, semble avoir été au départ consécutif à trois faits essentiels qui se sont déroulés dans les années 1850 à 1870 : - la maîtrise du captage du naissain sur collecteurs, alors...

An evaluation of the energy transfer between zoobenthos and water birds in the Mont-Saint-Michel bay was carried out from October 2003 until September 2004. Global consumption by waders is similar to that estimated on data collected 20 years ago, in spite of strong variations in seasonal occurrence and species composition of shorebirds populations in the bay. Total consumption (including gulls and predatory anseriformes) is about 2,15 g ash free dry weight/m2 /year, a very low figured if compared to results from the Wadden Sea. These two results seems to confirm the initial findings from the PNEC research program in the Mont-Saint-Michel bay: the bay is an oligotrophic system (oceanic type) presenting a strong functional inertness in the mid and long term,...

What is REMORA? REMORA &amp;#8722;REseau MOllusques du département Ressources Aquacoles&amp;#8722; (Aquaculture Resources Department Mollusc Network) is a surveillance network dedicated to the growth of hollow oysters Crassostrea gigas. In the past and in most production areas, observations were made on a regular basis. In 1993, homogenising experimental protocols between the different laboratories involved was decided, as well as using a common initial oyster batch, therefore organizing a network covering all of the French coasts. This network aims at providing, each year, the production's basic characteristics found in main oyster beds (growth reference). It also better characterizes variations and shows potential tendencies.

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...

French potters from « Manche ouest » harbours ish edible crab Cancer pagurus in English Channel, Iroise Sea and along north Biscay Bay shelf. Monthly landings of the offshore fleet analysed from logbooks for the period 1985-1987 indicate changes in fishing areas. The mean length of males, the mean length of females and the sex-ratio have been analysed by Principal Component Analysis in 1981-1987 samples. The heterogeneity between catches from different statistical rectangle (30 x 40 nautical miles) was great enough to deduce a way of raising composition from samples to total landings. It also offers the possibility to verifiy and correct declaration on geographical origin of landings.

Approche microbiologique de l'anchoitage.
Provedor de dados: 5
Autores: Campello, Francois.
The maturation of salted anchovies leads to a product of particular organoleptic properties. The manufacturers have to resolve many problems. A thorough investigation of the phenomenons which occur is necessary to resolve them. The maturation is conducted at different temperatures. The present paper reports the microbiological variations of the present microfloras, from hyper-halophilic to the non-halophilic, which escort organoleptical and biochemical ones chiefly at 20 degree C. If the maturation's temperature is maintained high (28 degree C) there is a strong proteolysis. At 20 degree C the organoleptical characters appear within 2 months.

The monitoring network IFREMER /REMORA is assessing, on a yearly basis, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year old ; and "adults" = two-years old), distributed among various stations of the main French oyster areas. Samplings are carried out in March, June, September and December. This network is a tool for trend estimations (geographic and chronological, on the national scale) ; it must not be considered as an accurate estimation of professional oyster ongrowings. With the exception of Spring mortalities due to poor initial quality of adult oysters and to difficulties in the counting of juveniles, the year 2000 appeared to be a year of low mortality. 2000 is a year of poor growth (61.5 g in average weight in...

Autores: Leguyader, F; Apaire, M; Besse, B; Billaudel, S.
Riboprobes developed in our laboratory were used for detection of enteroviruses and hepatitis A virus (HAV) in shellfish (cockles and mussels). After concentration elution, virus nucleic acids were extracted and purified. Hybridization was performed on a solid support according to the dot-blot technique, with (32P) UTP labelling of probes during transcription. Results show high shellfish contamination in samples: 63% enteroviruses and 67% HAV. Cockles were particularly contaminated: 89% enteroviruses and 84% HAV.

The shellfish industry in France
Provedor de dados: 5
Autores: Bonnet, Marc; Troadec, Jean-paul.
Bivalve farming is in France a major economical activity, which development was initiated in the mid of last century. It occupies nowadays 24 000 ha of seabottom, leased from the French State, and production figures are above 100 000 tonnes for cupped oyster and 40 000 tonnes for mussel ; these made a gross value of 1 300 millions francs in 1983. Moreover, it shows potential for promising development, by expanding to new areas, especialy in deep sea, or by introducing new species, such as the short neck clam, which production has just reached significant level (300 T in 1984). Long age and success of this cultivation activity come from the important advantages related to the biology and ecology of bivalves: food naturaly available, and of no use by another...

Depuration: An administrative overview

Autores: Somerset, I.
At the 1964 National Shellfish Sanitation Workshop, Mr. Eugene Jensen presented a thought-provoking paper outlining the rationale for the depuration of shellfish. Mr. Jensen noted that "we are committed to the principal that shellfish must be as safe to eat as other ordinary food" and that "the problems of assuring the sanitary quality of coastal areas will increase rather than diminish. This is not the same as saying that pollution will increase" (Jensen, 1964). It is recognised that additional use of the waters and shore areas will have adverse impacts on the water quality and shellfish resource quantity and quality. If we are to maintain a program which will permit the consumer to eat shellfish in any form they choose, we must develop the means to...

The ecosystems exploited by fishing are complex. The species which are sought after and their distribution rely on numerous processes, in time and space. The understanding of marine ecosystems requires important means and diverse information including those of professional fishing and scientific cruises. At first, scientific fishing cruises aimed to explore marine fauna and discover new halieutic resources. They were in line with the exploration cruises carried out by Prince Albert 1st of Monaco at the end of the XIXth century. However, since the beginning of the 1970s, they have been focusing on the quantification of the resources exploited by fishing.

The continuous obtention of different signals has been achieved for 9 days at a -fixed station during May 1988. The speed and direction of the currents have been monitoring concurrently with "in situ" turbidity and fluorescence in relation with the meteorological conditions. The concentration in particulate matter and the planktonic fluorescence fluctuated in direct relation with the water depth, the speed of the current and with the origin of the water masses. The oysters submitted to these large fluctuated conditions showed not constant filtration rate. The filtration calculated by turbidimeters (2 1 h-l g-1 dry weight) was three time less than the one achieved with fluorimeters (61 h-l g-1 dry weight).

A national program started in 1989 to drive researches on Ruditapes philippinarum brown ring disease correlated with a vibrio called P1. The researches have concerned epidemiological surveys on spats and adults, treatment methods, diagnostic techniques, and anatomical and functional studies about the vibrio-clam relations. The transmissions of the disease appeared mainly related to contaminated manila clam seeds, with secondary horizontal propagation. The brown ring formation appeared to be caused by a periostracum deterioration. Taking into account some of these results, an adapted cultural technique including special care of seeds and decreased densities was proposed to the farmers.

The exploitation of amphihaline species by marine and freshwater commercial fishermen in the Loire estuary in 1989, and by marine commercial fishermen in the Adour estuary from 1985-1991 is described in this study. This fishery employs 320 fishermen and represents a commercial value of 38 million FF. This is mainly due to the exploitation of glass eel, especially in the Loire River, the landings of which have decreased alarmingly. In the Adour River, the diversity of the exploited species and the total commercial value of drift gillnet catches - on the average 43% - in this fishery are high. The landings of migratory salmonid species are high and they may attain 25% of the total commercial value. This study emphasizes the uniqueness, the socio-economic...

Le réseau de suivi de croissance des moules dans les Pertuis Charentais a 3 ans d 'existence. L'année 2002 n'est pas une bonne année de croissance. Les mesures de gain de poids moyen journalier saisonnier soulignent un fort retard de croissance pour la période printanière (0,35 en 2002 contre 0,38 en 2001 et 0,69 en 2000). Ce manque de croissance n' est pas récupéré en été et reste équivalent à celui de 2001 (0,30). L'automne montre des résultats très variables, à l'avantage de l'élevage sur filières.

Autores: 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.

A detailed study of vegetative and reproductive phases of several populations of a common species of Ulva from Thau Lagoon (France, Mediterranean Sea) showed that the material is in good agreement with Asiatic Ulva pertusa Kjellman. Since October 1994, the date of its first observation in Thau Lagoon, U. pertusa has developed abundant reproductive populations. It is highly probable that this species was introduced at Thau along with oyster transfers from the Pacific. Ulva pertusa is new to the Mediterranean Sea.

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.

Stock characteristics of Atlantic salmon (Salmo salar) in France: a review

Autores: Prouzet, Patrick.
The general characteristics of the main salmon (Salmo salar L.) stocks in the Massif armoricain (Brittany and Lower Normandy), in the Loire-Allier and in the Adour-Gaves-Nive have been summarized. Due to the poor quality of the previous fishing statistics, there is no clear picture of the historical evolution of the salmon stock. However, a dramatic decrease in the endemic range of Atlantic salmon in France can be shown since the mid-18th century a nd more particularly during the last 50 years. The lack of precise informations describing the size of the catches and the levels of exploitation at sea and in the estuaries make it impossible to estimate the impact that exploitation has led on the evolution of salmon stocks. The mean age of salmon in freshwater...

Provedor de dados: 5
Autores: El Gharbi, Salwa; Rousset, Viviane; Raibaut, André.
Lernaeenicus sprattae is a blood-feeding copepod parasite of the pilchard, Sardian pilchardus . The larval stages of L. sprattae attach to the skin or the fins of the larval fish when the fish enter the lagoons. The mature, and in some cases ovigerous females of L.sprattae seek out the base of the fins or directly implant in the eye of juvenile or adult pilchards. The copepod has a particularly serious  effect at the site of infection: its feeding has a severe effect on the fish. The pilchard returns to its breeding grounds in the open sea at the end of summer; this migration allows the copepod to complete its reproductive cycle and a new cycle of infestation is able to begin.

The specific analysis of preys allows to determine the composition of cuttlefishes alimentary diet in natural conditions. This analysis based on exploitation of stomachal contents shows a majority of Fishes and Brachyura Crustaceans consumed. The alimentary diet with a Fish dominance in winter area (off Belle-Ille island) becomes a Crustacea dominance when adult cuttlefishes come in Morbihan Bay, in March, for reproduction. As for newly-born, they eat exclusively Crustacean Amphipoda and Macrura.

Polymorphisme enzymatique de trois populations de palourdes (Ruditapes decussatus L.) de Bretagne
Provedor de dados: 5
Autores: Moraga, D; Lucas, A.
The three populations studied were situated on the west coast of Brittany: to the North (Diben), to the West (Tinduff) to the South (Ile Tudy). 25 to 57 analysis were carried out on each of the 19 enzymatic systems where 27 loci had been recognized. Six of which were not interpreted, 10 were monomorphic, 11 polymorphic. Among these latter, the analysis of 4 of the loci were not used as the determination was too confused. Therefore, the comparison of the 3 populations was carried out on 7 polymorphic loci (EST3, HK2, LAP2, MDH1, MDH2, GPI, PGM2). Only a rare allele showed one qualitative difference; this coupled with slight quantitative differences in the distribution of the alleles did not permit to distinguish the three various populations. The genetic...

Introduction and objectives of the study: Understanding the operation modes of the coastline systems requires the study of the hydrodynamics responsible for transporting the whole of the chemical and biological elements of which they are composed. The idea of maintaining a close connexion between the physics, biology, geology and chemistry of the oceans is not new, and was for that matter the subject of a note in the first report of the International Council for the Study of the Oceans (ICSS) in 1902 (Sverdrup et al., 1954):  " it was seen from the beginning that the study of the physical conditions, of the chemical nature of the ocean waters, of the currents, etc., was of the greatest importance for the investigation of the problems connected with life,...

Recherche et identification de bactéries pathogènes au sein d'une écloserie nurserie d'huître creuse, Crassostrea gigas, en relation avec la mortalité estivale du naissain
Provedor de dados: 5
Autores: Waechter, Magali.
Summer mortality has been observed on oyster spat Crassostrea gigas since 1991 on french coasts. In our study, we deseribed symptoms observed during the mortality, especially adductor muscle weakness and we isolated strains on Zobell medium and TCBS from moribund spat. Strains isolated during a high mortality (60 %) were selected by experimental pathology on spat. Inoculation by bath led us to select a pathogenic strain (TNEMF6) for oyster spat. Phenotypic identification, phylogenetic study on 16S rDNA and quantitative DNA/DNA hybridisation showed that this strain belongs to Vibrio splendidus biovar II. Phenotyping and ribotyping with strains isolated during the study showed that only TNNIII7 and TNMB5 are similar to the pathogenic strain TNEMF6....

A 5-month experiment combining a geochemical survey of metals with a bioaccumulation study in batches of Crassostrea gigas was conducted in two shellfish farming areas and a marina in Normandy (France). Various endpoints at different levels of biological organization were studied. ROCCH data showed differences in biota contamination between the two shellfish areas but the present study revealed only slight differences in metallic contamination and biomarkers. By contrast, significantly different values were recorded in the marina in comparison with the two other sites. Indeed, higher levels of Cd, Cu and Zn were measured in the oysters from the marina, and these oysters also showed a poorer physiological condition (e.g., condition index, histopathological...

During the cruise EURHOGLI (Eutrophication by the Rhone of the Gulf of Lion) of the R.V. Le Noroit , a grid of stations covering the dilution area of the Rhone River has been carried out two times with a time interval of about two weeks. An exceptional growth during the two months preceding the cruise, has produced an important dilution effect over a wide spread areas. The absence of nutrients demonstrates their general consumption by biological activity. The tracer properties of the nutrient can be observed only in a small area near the mouth of the river. Nutrients are becoming the tracer of this dilution, and a great development of chlorophyll associated to this same area, show that nearly all the biological activity of nutrient assimilation is...

Estimation of Age, Growth and Fishing Season of a Palaeolithic Population of Grayling (Thymallus thymallus) Using Scale Analysis
Provedor de dados: 5
Autores: Guillaud, Emilie; Elleboode, Romain; Mahe, Kelig; Bearez, Philippe.
The fish remains sampled from archaeological sites are generally the result of human food refuse; therefore, the study of retrieved fish scales may provide reliable information on the season of capture and on paleoclimate and paleoenvironmental changes. Among Western European freshwater fishes, the grayling, Thymallus thymallus¸ has the most easily recognizable scales and is a commonly recovered species from Paleolithic contexts. This study, therefore, is based on the growth pattern analysis of modern and archaeological scales from grayling specimens. The modern specimens were collected monthly in France (n = 22), Switzerland (n = 16), Finland (n = 20) and Sweden (n = 10). Scale growth patterns were measured using numerical analysis to a high accuracy. The...

Autores: 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...

Autores: Migne, Aline; Trigui, Rima Jihane; Davoult, Dominique; Desroy, Nicolas.
The effect of an invasive infaunal suspension-feeding bivalve, the Manila clam Ruditapes philippinarum, on benthic inorganic carbon and nutrient fluxes was examined through in situ incubations. Measurements were performed in spring and summer on a tidal sandflat of the Rance estuary (south part of the Western English Channel) colonized by the Manila clam after its deliberate introduction in the 1990's. Benthic inorganic carbon fluxes were measured using light and dark benthic chambers both at emersion and immersion. Benthic nutrient fluxes were measured using dark benthic chambers at immersion. Inorganic carbon (IC) and ammonium sediment release under darkness at immersion reached 5.60 mmol m−2 h−1 and 441 μmol m−2 h−1 respectively for a clam density of...

The integration of fishing management into the ecosystemic approach has been recommended for many years by international consultative bodies; it is also written into international conventions and agreements. The implementation of the ecosystemic approach involves the development of programmes for monitoring exploited ecosystems in order to measure the effects of management steps. Plotting the results of these observations for operational reasons requires formalizing summary performance indicators.  IFREMER has carried out halieutic observation campaigns for some twenty years along the coasts of France from oceanographic ships and chartered ships. The objective of these campaigns is to produce abundance indices of species that are of halieutic interest....

Utilisation de critères fonctionnels (présence de spermatophore, maturation des ovaires) pour la détermination de la taille et de l'âge à maturité sexuelle des Nephrops norvegicus femelles de la région sud-Bretagne
Provedor de dados: 5
Autores: Morizur, Yvon.
The average length at which female Nephrops norvegicus attain their first maturity was determined during 1977 and 1978 by following the presence of spermatophores and development of the ovaries. During 1978, females were sexually mature at the age of 2 but in 1977 they did not mature before the age of 3. The cumulative maturity curves are sigmoid, due to an overlapping of Gaussian curves. A logistic equation was developed to calculate the percentage of mature females at each length. There is no evidence that the present fishing levels reduce the chances of a female with developing ovaries to be fertilized, since 90 to 100% of such females bear spermatophores.

During the years 2008 to 2013 several observations of catches were planned on board of set netters fishing in the bay of Biscay, in the English Channel, in the North sea and in the Mediterranean area (around Corsica). All the observations were done on nets without pingers and they were pooled to provide an average bycatch rate of marine mammals by fleet. Estimates of annual bycatch by using the fishing efforts of the year 2012 were provided by fleet. Harbour porpoise Phocoena phocoena was the most common bycatch in set nets. An average annual estimate of 600 harbour porpoises was obtained for the French fleet; other species recorded in set nets were mainly common dolphin Delphinus delphis, striped dolphin Stenella coeruleoalba and the two species of seals...

Studies concerning the respective role of free-living and particle-bound bacteria in pelagic ecosystems, sometimes gave opposite results. The comparative distribution of these bacterial patterns was studied in two sites of Brittany. In the Bay of Brest, a shallow and semi-enclosed area, the bacterial communities were dominated by the free-living forms, except during the phytoplankton bloom, which was accompanied by a clear increase of the particle-bound forms. Off the west coasts of Brittany, the Ushant front separates stratified water masses from mixed water masses. The distribution of particle-bound bacteria fluctuated according to the structure of the water masses and in mixed waters, was related to particulate matter from different origins. Results...

Introduction de l'huître creuse Crassostrea gigas en France
Provedor de dados: 5
Autores: Grizel, Henri.
La production d'huîtres creuses françaises est actuellement supérieure à 100 000 tonnes. Elle est assurée par la culture d'une seule espèce, Crassostrea gigas, élevée dans la plupart des centres ostréicoles. Cette espèce s'est avérée résistante aux différentes maladies qui ont affecté tout d'abord l'huître creuse, Crassostrea angulata (Viroses), puis l'huître plate Ostrea edulis (Marteilia refringens et Bonamia ostreae). Ainsi, malgré toutes les controverses que cette implantation a provoquées, le fait essentiel est que depuis 1970-1971, la profession ostréicole a pu rester active, grâce à la culture de C. gigas, et ce, malgré les nombreux problèmes auquels elle a du faire face.

Reproduction de la langoustine, Nephrops norvegicus dans la region sud Bretagne
Provedor de dados: 5
Autores: 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.

15% of the shellfish production in France comes from natural deposits and the other 85% from farming. Years 1980-1990 showed a slight decrease in the shellfish production then a resurgence from 1985 onwards, an increase in the oyster production and a strong decrease in mussel production at the beginning of the 1980's followed by a resurgence due to the increase of open sea activity. In France, the shellfish market represents 300,000 tons, divided between oysters (40%), mussels (30%) and scallops (15%). Importations of mussels and scallops in order to supply the domestic market are important. On the other hand, external trade flows are very low as far as oysters are concerned: France is the only important market for oysters in Europe. (unverified OCR)

Projet de station de purification des coquillages dans le nord de la France
Provedor de dados: 5
Autores: Morel, M; Salamon, W.
European regulations (Directive EEC/15.07.91) provide that marketing of live bivalve molluscs intended for human consumption must comply with strict bacteriological criteria. In order to comply with these requirements along the Nord/Pas de Calais coast and to preserve shellfish culture activities, a transfer through a depuration plant is the only solution at the present time. IFREMER, with the support of the Nord/Pas-de-Calais regional authorities, conducted an initial study on the use of UV for mussel depuration and on the design of a shellfish depuration plant. This study was used as a basis by TECHMAR Company to design a project for a modular type plant, under contract from the Nord/Pas-de-Calais Region. The basic module consists of two ponds with a...

Before and after wasting disease in common eelgrass Zostera marina along the French Atlantic coasts: a general overview and first accurate mapping
Provedor de dados: 5
Autores: Godet, L; Fournier, Jonathan; Van Katwijk, M; Olivier, F; Le Mao, Patrick; Retiere, C.
We examined the original manuscripts of a French national survey conducted in 1933 on the state of common eelgrass Zostera marina beds along the French Atlantic coasts during the period when wasting disease struck the entire North Atlantic population in the 1930s. Based on GIS related techniques and old sets of aerial photographs, we present the first accurate mapping of the Z. marina beds before wasting disease occurred and assess their spatial recolonization since the 1950s in the Chausey Archipelago (France), which contains large Z. marina beds. The national survey confirmed that the Z. marina beds almost totally disappeared from the French coasts during the 1930s. However, the disease symptoms seem to have begun locally a few years before. On the study...

Autores: Goyard, Emmanuel.
What is REMORA? REMORA &amp;#8722;REseau MOllusques du département Ressources Aquacoles&amp;#8722; (Aquaculture Resources Department Mollusc Network) is a surveillance network dedicated to the growth of hollow oysters Crassostrea gigas. In the past and in most production areas, observations were made on a regular basis. In 1993, homogenising experimental protocols between the different laboratories involved was decided, as well as using a common initial oyster batch, therefore organizing a network covering all of the French coasts. This network aims at providing, each year, the production's basic characteristics found in main oyster beds (growth reference). It also better characterizes variations and shows potential tendencies.

Fécondités individuelle et par recrue du homard européen Homarus gammarus (L.) des cotes françaises
Provedor de dados: 5
Autores: Latrouite, Daniel; Morizur, Yvon; Raguenes, Gerard.
Several relationships between the fecundity and the weight or the size of females have been studied for three different (based on "eye-index") stages of incubation. The relationship between the average weight of eggs at the beginning of incubation and the size of the females shows that the egg size varies according to the female's size. Loss of eggs during incubation has been studied ; the average loss between the two extreme stages of incubation is around 27%. This is a lowered value of what accurs during the whole incubation period. Egg losses are greater for small females than for big females. The annual frequency of spawning and size at first maturity have been determined in for differents fishing effort than by the commercial size.

The network REMORA by IFREMER quarterly follows each year 2 batches of Pacific cupped oysters Crassostrea gigas ("juveniles"= 1 year old; and "adults" = 2 years old) on various sites among the main French oyster areas. The network monitored 46 sites in 2004, including the 7 new sites added in 2003. The network REMORA thus assess seasonal survival, growth and quality of cupped oysters. It is a tool for trend estimations, ecosystem management and a reference frame for scientific studies. Globally speaking, the year 2004 was a good year for oyster farming, with a low mortality and a fast growth. The rearing yield (survival x growth) reached 2.0 for adults instead of 1.8 usually. However, the meat index remained close to the average inter annual data....

Introduction: With the objective of diversifying current fishing and at the request of professionals in Aquitaine, the Regional Commission of Maritime Fishing and Marine Breeding (CRPMEM) of Aquitaine has started a discussion about the possibilities of opening a shellfishery. In the context of this course of action, and because of the absence of information on the presence and size of the resource, the CRPMEM of Aquitaine asked IFREMER's Halieutic Resources Laboratory of Aquitaine (LRHA) for assistance in acquiring information on the subject. At the same time, a prospective analysis study of the exploitation of shellfish off the coast of Aquitaine—regulation and business section—was performed by the CRPMEM of Aquitaine (Coiffec, 2006).  At that same time,...

Les dinophycées pélagiques et benthiques du Golfe de Gascogne sud de la Bretagne à Arcachon
Provedor de dados: 5
Autores: Paulmier, Gerard.
Les microphytes planctoniques et benthiques du Golfe de Gascogne sont relativement diversifiés. Cette diversification est probablement en rapport avec la situation hydrologique particulière de cette région enrichie par des mélanges de masses d'eau de diverses origines et par des apports continentaux importants. Dans ce contexte, les dinophycées sont nombreuses et variées et occupent toutes les niches écologiques. 230 taxons ont été répertoriés. Quelques espèces sont connues pour provoquer périodiquement des colorations de la mer "eaux rouges" et quelques-unes sont maintenant redoutées pour leur toxicité.

Lutte biologique contre la proliferation de l'etoile de mer: Asterias rubens en baie de Quiberon
Provedor de dados: 5
Autores: Barthelemy, G.
In 1989 and 1990, the Brittany Region has conceded a subvention to the shellfish professional organisation, for a study on the sea star proliferation Asterias rubens ; this species is a predator of reared oysters in subtidal zone, specially in the Bay of Quiberon (South Brittany). The sea star species Luidia ciliaris has been identified as an A. rubens predator in laboratory. In presence of A. rubens and various molluscs species, the exclusive prey L. ciliaris is A. rubens . Even deprived of A. rubens they do not eat any bivalve. The first result led us to set up an introduction test of L. ciliaris as the main predator of A. rubens and their relative spatial stability. In prospect of mass introduction of L. ciliaris in the bay, reproduction experiments...

Autores: De Montaudouin, Xavier; Arzul, Isabelle; Caill-milly, Nathalie; Khayati, Alice; Labrousse, Jean-michel; Lafitte, Céline; Paillard, Christine; Soudant, Philippe; Goulletquer, Philippe.
In 1972, France underwent an oyster (Crassostrea angulata) crisis and urgently needed to diversify its aquaculture. Thus, Asari clam (Ruditapes philippinarum) was introduced at that time for aquaculture purpose, concomitantly with the introduction of Pacific oyster (Crassostrea gigas). All Asari clam adults and spat originated from the same area (Puget Sound, WA, USA). After a promising start and the implementation of a national Research &amp; Development program, Asari clam culture rapidly faced a series of concomitant handicaps: firstly, in spite the fact that cultural practices were optimized and locking points addressed, leasing ground availability was limited during the 1980s’ due to certain reluctance from oyster farmers to share their leases and/or...

Introduction and objectives of the study: Understanding the operating modes of the coastline systems requires the study of the hydrodynamics responsible for transporting the whole of the geobiological compartments of which they are composed. The idea of maintaining a close connexion between the physics, biology, geology and chemistry of the oceans is not new, and was for that matter the subject of a note in the first report of the International Council for the Study of the Oceans (ICSS) in 1902 (Sverdrup et al., 1954): ... it was seen from the beginning that the study of the physical conditions, of the chemical nature of the ocean waters, of the currents, etc., was of the greatest importance for the investigation of the problems connected with life, that...

Autores: Sournia, Alain; Belin, Catherine; Billard, Chantal; Catherine, Martial; Erard-le Denn, Evelyne; Fresnel, Jacqueline; Lassus, Patrick; Pastoureaud, Annie; Soulard, René.
A dinoflagellate has produced green-water events along the Atlantic and English Channel coasts of France since 1982. It differs morphologically from each of the 12 taxa or so of green gymnodinoid dinoflagellates previously known. As some morphological details, as well as their variability, remain to be ascertained, this organism is illustrated and described here under the provisional designation of Gymnodinium "sp. 1982". The presence of chlorophyll b has been confirmed by HPLC analysis but it could not be ascertained whether true chloroplasts are present, or symbionts. The distribution is coastal and estuarine. The number and intensity of the outbreaks may be related to river runoff and to the amount of preceding rainfall. An encysted stage is described....

Pêche de la langouste rouge Palinurus elephas en france. Eléments pour fixer une taille marchande
Provedor de dados: 5
Autores: Latrouite, Daniel; Noel, Philippe.
From the end of XIX century to the 1950', spiny lobster (Palinurus elephas) fishing has been an important economical activity for potters of Brittany and led to landings over two thousands tons. Later, impoverishment of traditional fishing grounds and closure, to French fleet, of foreign fishing area obliged a reconversion of potters toward crabs (edible crab and spider crab). Recently in the 80', development of a netting activity has restarted catches of spiny lobster (at a modest scale). Presently, the only reglementary measure concerning this species/metier is a national minimum legal size (total length) but European Commission has wished that a European MLS would be established. In that aim, this paper presents the main features of spiny lobster...

Présence d'un Protogonyaulax sp. sur le littoral atlantique français pendant l'hiver 1987
Provedor de dados: 5
Autores: Lassus, Patrick; Bardouil, Michele.
A dinoflagellate belonging to Protogonyaulax genera and forming more than 20 cells chains was observed from November 1987 to February 1988 in Vilaine Bay and in the west ofIle d'Yeu (France). This species was not detected in coastal phytoplankton during preceding surveys. Close to Protogonyaulax affinis it seems to be a winter developing species for this coastal area. Vertical distribution shows in december a migration of the patch towards deeper layers. Increasing occurrences of species belonging to Protogonyaulax (Alexandrium Balech) genera inshore or coastal waters need to pay more attention to the taxonomy of such organisms. Some species are effectively well known as poisons producers.

Introduction: Through the combined works of research, local communities and professionals, a new activity has been created, "vénériculture", i.e. clam farming. Thanks to the knowledge acquired in research as well as production in the shellfish field, clam production results followed shortly thereafter. Rightly so, only 10 years have elapsed since the beginning of the research and the actual production phase (500 t) involving about 300 professionals. Research conducted by IFREMER positively contributes to the creation of new trades as well as diversity within existing professions. Clams are marketed nationally as well as exported. French producers are truly competent, but the prospect of open borders and increasing competition requires maintaining a high...

A fisrt survey designed to estimate the impact of the fishery on the multispecific population of the slope has been carried out from June 26th to July 20th 1996 on board of the French R/V Thalassa. This survey took place West of Scotland, between 55 degrees and 57 degrees of latitude North, on an area from where data before exploitation were available and where fishing activity was intensive since the 90's. On this area, the analysis of the species composition by haul only showed that the fish assemblage was structured according to depth. Such a conclusion was not new. However, the positioning of the hauls on two smaller sectors characterized by different slopes and bottoms, and probably by a lesser fishing intensity on the one with rougher bottom did not...

Autores: Quero, Jean-claude; Cendrero, O.
Estimation of changes in the relative abundance of fish species in catches off Arcachon, on the shelf and in the Bassin d'Arcachon, from 1727 to the present day, shows that some previously dominant species are becoming scarce. Some are actually not caught now in the south of the Bay of Biscay. Among these are the large bottom-living elasmobranchs with low reproduction rates, such as Echinorhinus brucus, Squatina squatina, Raja batis, Raja brachyura, Dasyatis pastinaca, Myliobatis aquila, Galeorhinus galeus, Mustelus asterias, Raja clavata, ,.. and some actinopterygians, such as Trigla lyra, while catches of Eutrigla gurnardus are much reduced. Bottom trawling is principally responsible for these reductions but all fishing methods used there have...

Can Offshore Wind Energy Be a Lever for Job Creation in France? Some Insights from a Local Case Study
Provedor de dados: 5
Autores: Kahouli, Sondes; Martin, Jean Christophe.
The French government has launched three separate calls for tender in July 2011, March 2013, and December 2016 to install 3.5 GW of offshore wind. In addition to contributing to the fulfillment of environmental commitments, the deployment of offshore wind energy is expected to be a lever for economic development. To assess gross economic impacts, mainly in terms of job creation, we built a regional input-output model of the wind farm off Saint-Brieuc located in the region of Brittany, north-western France. Our model indicates that the project will have positive effects on Brittany’s economy.

This document is a result of an environmental impact study carried out between 1993 and 1995 on the site of a marine trout culture located in the Harbour of Cherbourg, France. It deals with the solid waste of the farm and concems deposition rate, sediment analysis and chemistry (fine fraction &lt; 63 ~m, organic matter, carbon, nitrogen, copper and zinc), bottom living organisms and underwater video monitoring. The impact observed is very moderate and localised. This is mainly due to the strong d)'TIamics and flushing rate of the site. A seperate volume of the same study deals with dissolved waste and concems the water mass (volume 1 : water and pelagos). (Not controlled OCR)

The incidence of phytoplankton communities sequences on toxic dinoflagellate Dinophysis acuminata occurrence was studied in the course of summer 1983, in Vilaine Bay. Despite difficulties in finding obvious relationship between occurrences of that species in the fields and preceding species it nevertheless may be emphasized: 1) a real perturbation of ecosystems is noticeable (rank-frequency diagrams); 2) the amount of sampling stations might be reduced in so far as representative stations are maintained.

Interplay between abiotic factors and species assemblages mediated by the ecosystem engineer Sabellaria alveolata (Annelida: Polychaeta)
Provedor de dados: 5
Autores: Jones, Auriane; Dubois, Stanislas; Desroy, Nicolas; Fournier, Jerome.
abellaria alveolata is a gregarious polychaete that uses sand particles to build three-dimensional structures known as reefs, fixed atop rocks or built on soft sediments. These structures are known to modify the local grain-size distribution and to host a highly diversified macrofauna, altered when the reef undergoes disturbances. The goal of this study was to investigate the different sedimentary and biological changes associated with the presence of a S. alveolata reef over two contrasting seasons (late winter and late summer), and how these changes were linked. Three different sediments were considered: the engineered sediment (the actual reef), the associated sediment (the soft sediment surrounding the reef structures) and a control soft sediment (i.e....

In costal systems, particulate organic matter (POM) results from a multiplicity of sources having their respective dynamics in terms of production, decomposition, transport and burial. The POM pool experiences thus considerable spatial and temporal variability. In order to better understand this variability, the present study employs statistical multivariate analyses to investigate links between POM composition and environmental forcings for a panel of twelve coastal systems distributed along the three maritime regions of France and monitored weekly to monthly for 1 to 8 years. At multi-system scale, two main gradients of POC composition have been identified: a ‘Continent-Ocean’ gradient associated with hydrodynamics, sedimentary dynamics and depth of the...

Le renouvellement des flottilles en France de 1945 à 1983 : discours, contexte et réalisations
Provedor de dados: 5
Autores: Meuriot, Eric.
This study recounts the policies on fishing fleet renewal in France from 1945 to 1983. The views held by sector professionals and the public authorities on the role of fleet renewal in fisheries economy are put into context in terms of stock abundance, access to fishing grounds, the state of the market, etc. The consequences of the lack of consistent guidelines for distributing the resources between competing fleets, foreign or national, are presented. The limits of the stances held on technical "progress" and "reasonable" management of resources are discussed. Other, complementary lines of research to undertake are proposed as a conclusion. Many tables and figures illustrate the text.

Public-aided crises in the French fishing sector
Provedor de dados: 5
Autores: Mesnil, Benoit.
According to the media the French fishing industry has been in permanent state of crisis for the last 40 years. This paper recounts the events surrounding three major episodes of crises (late 1970s, mid-1990s, and early 2000s), and the measures taken by governments to resolve them. Invariably, these involved the distribution of sizeable amounts of public aids, in different forms, to the fishing sector. The efficacy of the subsidy programmes is discussed with reference to the goals stated by their proponents, regarding trade balance, competitiveness, profitability, employment and safety. Overall, the massive aids granted to the sector (comparable with the gross value of landings, annually) have not achieved the stated objectives and, paradoxically, have...

Le complexe «Dinophysis acuminata»: identification des espèces le long des côtes françaises
Provedor de dados: 5
Autores: Lassus, Patrick; Bardouil, Michele.
From seawater samples collected between 1984 and 1989 in 12 French coastal areas, a morphometric study have been realised on Dinophysis genera restricted to "acuminata" like species. Simple morphological criterias are given as suitable for discrimination of four dominant species occurring during toxic episodes in shellfish farms (Diarrheic Shellfish Poisoning): Dinophysis c-closed-integral. sacculus, D. c-closed-integral. acuminata, Dinophysis sp. and D. c-closed-integral. norvegica. This last species cannot be included in the "acuminata complex" and produces temporary blooms along southern Brittany coasts. Pending a more precise diagnosis it is recommended to clarify the relationship between toxin composition and each species previously described.

Autores: Yahyaoui, A; Brusle, J; Pasteur, N.
15 Types of allozymes were electrophoretically studied and variability of 24 genes analyzed and compared between Atlantic and Mediterrancean elvers (Anguilla anguilla ). No genetic difference was observed. The genetic homogenity agrees with a similar origin, the Sargasso Sea. Identity of enzymatic genes as found between different lots in culture and variation in growth was rather due to comportemental patternlike overcrowding than to genetic differences.

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)
Provedor de dados: 5
Autores: 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...

Despite great expectations in the Seine River Basin, the WFD did not reduce diffuse pollution

Autores: Bouleau, Gabrielle; Barbier, Rémy; Halm-lemeille, Marie-pierre; Tassin, Bruno; Buchs, Arnaud; Habets, Florence.
European stakeholders engaged in combatting the eutrophication of the North Sea welcomed three Water Framework Directive innovations: a more holistic approach to quality, the binding nature of WFD objectives, and greater public participation. Twenty years later, however, there has been a disappointing amount of progress in the reduction of diffuse pollution. In the Seine River Basin, the amount of livestock rearing is low; yet the basin is subject to significant diffuse pollution due to agriculture. This paper reports our study of this case; we examine the literature on WFD implementation policy in order to identify the physical and social causes of this failure to reduce diffuse pollution. We show that the nitrates, phosphorus, and pesticides that affect...

Autores: Miossec, Laurence; Girard, Sophie; Czerwinski, N.
The first national census concerning shellfish culture in France was carried out in 2002. The main purpose was to provide accurate and comprehensive information on the number and structure of the companies using an in depth review of production factors (leases, plants, equipment's, labour and qualifications), and a survey of cultural practices up to the market level. Moreover, the census aimed to quantify the bivalve sales dedicated to consumption and to measure the livestock transfers among rearing shellfish production areas at different developmental stages: spat, intermediate products and fully grown marketable products. The French oyster production reached 109 000 metric tons in 2001. The main production was observed in Poitou-Charentes region...

Action des facteurs hydrologiques et sédimentaires sur le budget énergétique de la palourde japonaise Ruditapes philippiarum élevée dans un écosystème estuarien (Bassin de Marennes-Oléron, France)
Provedor de dados: 5
Autores: Daou, Rafik.
Afin d'étudier l'action du sédiment sur les populations de Ruditapes philippinarum, 12 000 individus ont été répartis en 1986 sur 3 substrats dans le bassin de Marennes-Oléron. Tous les paramètres du milieu sont analysés sur les 3 sites pendant un cycle annuel parallèlement aux suivis biométriques, biochimiques et énergétiques sur les animaux. Ainsi dans ce secteur d'élevage "Les Doux" où l'influence estuarienne (Charente) est faible, les phénomènes circadiens, régissant la dynamique sédimentaire, n'affectent pas la distribution du matériel dissous. L'étude des différents fractions sestoniques au dessus de chaque parc montre qu'ils sont recouverts par la m^me masse d'eau.  Par ailleurs, les effets négatifs des sédiments à fortes teneurs pélitiques sur les...

Physiological processes of two populations of Mytilus edulis from the Atlantic coast (Marennes-Oleron, France) and from the Baltic coast (Gdansk, Poland) are compared. These parameters are discussed according to the physiological state of the populations (gametogenesis, spawning) and to the environmental abiotic (temperature, salinity) and biotic measurements (seston, chlorophyll). Two periods induce the use of energetic reserves from the flesh. The first one is due to the reproduction period (between February and May in the Bay of Marennes-Oleron and during June-July in the Bay of Gdansk), the second one to the bad winter trophic conditions. The physiological answers of these two populations during the two periods shows that different strategies take...

Long-term and millennial-scale climate variability in northwestern France during the last 8850 years
Provedor de dados: 5
Autores: Naughton, F; Bourillet, Jean-francois; Fernanda, M; Turon, J; Jouanneau, J.
Vegetation and quantitative climate reconstructions from a northwestern France shelf core (VK0358Bis) show orbital and suborbital climate variability for the last 8850 years in this region. A long-term cooling trend in summer temperatures, marked by gradual temperate and humid forest decline, parallels cooling in Greenland and the decrease of mid-latitude summer insolation reduction until at least 2000 cal. yr BP. At the long-term scale, the lowering in seasonal contrast revealed by vegetation changes follows the increase of precession. Corylus woodlands spread at the expense of deciduous Quercus forest, between 8740 and 8390 cal. yr BP, linked with the high seasonality conditions that, counterbalancing the long-term astronomical forcing trend, were...

Following exceptional outbreak of toxic dinoflagellate species in Vilaine Bay (summer 1983) a survey was carried out: variations in phytoplankton abundance and distribution in water and in mussel guts were followed. In the same time toxicity studies using mouse-test were performed with contaminated shellfishes, and mouse-test calibration was attempted. In spite of sampling and analysis conditions could be open to criticism, results obviously showed relation between shellfishes toxicity and occurrence of responsible species: Dinophysis acuminata.

Introduction: To develop its 2005-2009 strategic plan, IFREMER made two prospective analysis studies in 2003: a thematic prospective analysis and a sectorial prospective analysis. The "aquafarming" sectorial prospective analysis, based primarily on an IFREMER idea, particularly brought to light the difference in nature of problems posed by the future evolution of shellfish farming, fish farming and other stockbreeding (pearl farming and shrimp farming). In addition, the prospective analyses made on an international scale by the FAO (2002, 2004) and the IFPRI (2003) emphasise that the development of aqua farming is the required condition for satisfying world demand of consumer aquatic products, given the foreseeable weak growth, indeed, the stagnation of...

internal architecture of an incised valley-fill on a wave- and tide-dominated coast (the Leyre incised valley, Bay of Biscay, France). The Leyre incised valley shows a specific strata architecture related to its wave- and tide-dominated depositional environment. The low-stand systems tract has been totally eroded by the tidal ravinement surface and the valley is entirely filled by the transgressive systems tract. The Leyre and the Gironde incised valleys have been formed within the same depositional environment and the same stratigraphic framework. Consequently, the description of the internal architecture of the Leyre incised valley enables to complete the stratigraphic model of the wave- and tide-dominated incised valleys set up by Allen et Posamentier...

Autores: 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.

Eurytemora affinis hirundoides is the most abundant copepod in the Gironde Estuary which is submitted to strong salinity gradients. The response of the populations to these gradients is measured by following the variation of simple biometric characteristics. The observed variations reflect the influence of two important factors: salinity and turbidity.

Traitement de l''eau par ultraviolets, application a la purification des coquillages
Provedor de dados: 5
Autores: Cailleres, J.
The germicide properties of ultra-violet radiation in a wave length ranging from 100 to 400 mm were already discovered back in the late 19th century. These properties specific to UV-C radiation (200-280 mm) result from its action on the nucleic acids of the micro-organisms. Each micro-organism, depending on its composition, therefore presents a specific sensitivity to this radiation.

First results of an epidemiological study on oyster (Crassostrea gigas) mortality events in France during summer 2008
Provedor de dados: 5
Autores: Miossec, Laurence; Allain, Gwenhael; Arzul, Isabelle; Francois, Cyrille; Garcia, Celine; Cameron, Angus.
Abnormal mortalities occurred in most oyster producing areas in France during the summer of 2008.  The mortalities were sudden and severe (up to 100%) and mainly affected 6 to 18 month old juveniles.  Only Crassostrea gigas species was affected.  The cause of the mortality was unclear but OsHV-1 virus and bacteria belonging to Vibrionaceae family were frequently detected in affected populations. An epidemiological study was commenced in autumn 2008 in order to identify factors associated with, and the cause (or causes) of these mortalities.  This paper presents the results of the first (descriptive) part of this investigation.  The objectives were to identify the affected population and to describe the pattern of mortalities in time and space.  Mortality...

The spionid polychaete Boccardia proboscidea Hartman, 1940 is a tube-dweller and shell/stone-borer widely occurring in temperate waters across the world and considered invasive in many areas. It was originally described from California, USA, and later reported from Pacific Canada, the Asian Pacific, Australia, New Zealand, Argentina, South Africa, and northern Europe. The Bayesian inference analysis of sequence data of three gene fragments (836 bp in total) of the mitochondrial 16S rDNA, nuclear 28S rDNA, and Historie 3 has shown that individuals from the Pacific coasts of Canada and the USA, Argentina, Australia, South Africa, the United Kingdom, and Mediterranean France were genetically very similar (maximal average p-distance value, 0.49%, was between...

Autores: Laubier, Lucien; Le Moigne, Morgan; Flammarion, Patrick; Thybaud, Eric; Cossa, Daniel.
On December 11, 1999, Erika, an oil tanker flying the Maltese flag and loaded with 31 000 t of heavy fuel oil, was making its way from Dunkirk to Livorno when it encountered difficult weather conditions Southwest of the Brittany coast gale force winds 8 to 9 and 6 mwaves). On the morning of 12th December, the captain broadcast an SOS; his vessel was breaking in two, approximately 30 nautical miles to south of Penmarc'h Point (Fig. 1; Finistère, France). The fore section of the vessel sank during the night of the 12-13 December and the aft section was taken in tow on the morning December 13, but subsequently sank in the early afternoon. Both parts lay in 120 m of water and were located 10 km apart. Approximately, 19 000 t of heavy fuel oil were spilled into...

The monitoring network IFREMER/REMORA in Thau lagoon is assessing, on a yearly basis, mortality, growth and quality criteria distributed among 6 stations. Samplings are carried out in March, June, September and December. 2003 is a year with a very important mortality in Mèze and Marseillan area due to an anoxy and an anormal mortality at Bouzigues Nord in december. The growth rate is always better than others French oysters areas. Afnor index is high (beetwen 13.7 and 16.5 in december), so the totality of the oysters are classifed in "Spéciales". Polydora sp. Index is important but the initial stock was first infected. The valve quality is good, with no gelatine, except on Bouzigues South.

Qualite sanitaire des coquillages apres passage en bassin insubmersible aere
Provedor de dados: 5
Autores: Piclet, Guy; Le Mao, P.
The temporary bad bacteriological results in some shellfish harvesting areas in Brittany (France) lead us to recommand the use of insubmersible aerate tanks in shellfish plant. The shellfish depuration kinetics are as good as those noted in purification plants using chemically or physically purificated water. The generalisation of this technic to a regional scale corroborates its efficiency and allows us to fix good practice rules. The observance of these rules must lead shellfish-grower to sell, permanently, bacteriologically proper products.

Autores: Miossec, Laurence; Allain, Gwenhael; Arzul, Isabelle; Francois, Cyrille; Garcia, Celine; Cameron, Angus.
En 2008, des mortalités massives d'huîtres creuses (Crassostrea gigas) ont été recensées en France pendant l'été. Ce phénomène, observé de façon récurrente sur les côtés françaises depuis le milieu des années 70, a présenté un caractère exceptionnel en 2008 car il a été observé simultanément dans tous les bassins ostréicoles. De plus, les taux de mortalité calculés ont été particulièrement élevés (80 à 100 % pour de nombreux lots). La détection, fréquente et souvent simultanée, d'herpèsvirus OsHV1 et de plusieurs bactéries de la famille des Vibrionacées dans le cadre de la surveillance menée par le réseau national Repamo (réseau de pathologie des mollusques) a mis en évidence le caractère infectieux de l'épisode épidémique 2008.

The monitoring network IFREMER /REMORA is assessing on a yearly basis, from February to December, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year class ; and "adults" = two-years class), deployed among various stations of the main French oyster areas. This network is a tool for trend estimations (geographic and chronological, on the national scale) ; it must not be considered as an accurate estimation of professional oyster ongrowings. Based on REMORA results, generally tallied with professional observations, 1998 on the whole was a second year of low mortality. However several areas remained affected by significant mortalities : the baie des Veys (in Normandy), Morlaix and Pen-Bé (in Brittany) and Marennes (in...

The scientist community, the fishing organisations and all involved parties show a growing interest in an integrated project management of the sea space exploited by fishing communities. A key to reach such a target is to make available reliable and precise scientist data on the different components of the fishing systems.  For about twenty years, and in its mission to support the development of an integrated management for a sustainable use of marine resources, Ifremer has been organising monitoring campaigns of fishery resources along the shores of France. These campaigns aim at providing abundance indicator on species of interest. They consequently provide an essential knowledge base to characterize and trace the status of exploited fish and...

La malacofaune marine d''un site neolithique de l''Ile d''Oleron (Charente-Maritime): Questions posees au biologiste
Provedor de dados: 5
Autores: Gruet, Y; Laporte, L.
The species which have been identified in this Neolithic site are still living along the Bay of Biscay coasts. One of them, Haliotis , has recently disappeared from the Oleron Island. Some of them, as the very fruitful Patella and Monodonta lineata , have certainly been gathered and devoted to food. Others, as Nucella lapillus , have only been used to make pearls. And some others, Cardium for instance, could have been devoted at the same time to food and pearls. The study of the current biota of the different species allows the biologist to indicate where the shells might have lived: rocky or sandy shores, sheltered or exposed shores, intertidal or subtidal environment. The knowledge of the possible biota is an indication of the areas of the prehistoric...

Travail domestique et travail salarié des enfants dans le monde rural (le canton de Marines vers 1830)

Autores: Boudjaaba,Fabrice; Herment,Laurent.
In this article, using nominative census data of 1836 for 25 villages located at around 50 kilometers in the north of Paris, we examine who worked and who did not within each household. We focus on young women to assess the condition in which they entered the labor market without leaving their parents&amp;#8217; household. We think that such a gender approach can help us to assess the parameters which stimulate the entrance into labor market with reference to household composition, and the level of wealth of households. In the following section we first describe the sources we have used. In the second section we study the links between qualification of children and household composition. In the third section we propose a model to understand and assess the...

Trifurcula (Glaucolepis) melanoptera sp. n. is described from southern Europe, where it is widespread. It is closely related to the Central Asian T. (Glaucolepis) raikhonae Puplesis, which is redescribed. Together they form the raikhonae species group. Sinopticula Yang is here synonymized with Glaucolepis Braun, its only species S. sinica Yang is tentatively regarded as closely related, if not conspecific with T. raikhonae. The distribution is mapped. On the basis of recent Chinese findings the larvae are assumed to be gall-makers on Prunus branches. Some phylogenetic and biogeographic remarks are given.

The Common toad Bufo bufo sensu lato is a widespread, morphologically conserved taxon. Recent studies have uncovered deep genetic differentiation between population groups, highlighting the need to revise the current taxonomy of the group and recognize additional species. Here we investigate patterns of variation in molecular (a mitochondrial DNA restriction enzyme assay and sequence data for two nuclear DNA fragments totalling 979 bp) and 17 morphological variables in Northern France where two of these groups meet (B. bufo sensu stricto and B. spinosus), in order to delineate their contact zone and uncover characters that would allow discrimination of the two taxa. Mitochondrial DNA data show an abrupt transition from areas where B. bufo is present to...

Autores: 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...

Provedor de dados: 16
Autores: Gittenberger, E.
To provide background information for a proposal to the International Commission on Zoological Nomenclature to suppress five subjective senior synonyms of Trochoidea geyeri, the synonymies of this and some other hygromiid species are given. The nominal taxa that are dealt with concern species that are conchologically more or less similar. These species were studied to minimize the risk that even more unused senior synonyms of T. geyeri would be discovered, which would require an additional ruling of the Commission. Distributional data and short conchological diagnoses are added to increase the usefulness of the present paper.

The following three species are redescribed: Sminthurus viridis (Linnaeus, 1758), Sminthurus nigromaculatus Tullberg, 1871, and Sminthurus multipunctatus Schäffer, 1896. Four new species are described from France and Spain: Sminthurus bourgeoisi n. sp., Sminthurus bozoulensis n. sp., Sminthurus leucomelanus n.sp.,and Sminthurus hispanicus n. sp. The importance of the ontogeny of chaetotaxy is stressed. Indeed, not all species acquire the secondary chaetotaxy in the same instar, and for these characters the most informative instar is not the adult but the third juvenile instar. The study of such characters involves the clustering of similar characters. A short discussion is given about this issue (selection of characters and clustering criteria).

Comparative study of the hyperbenthos of three European estuaries
Provedor de dados: 27
Autores: Mees, J.; Fockedey, N.; Hamerlynck, O.
The hyperbenthic fauna of the subtidal channels of the Eems (N. Netherlands), Westerschelde (S.W. Netherlands), and Gironde (S.W. France) estuaries was sampled within a 15-day period in summer 1991. In each estuary, quantitative samples were taken at regularly spaced stations covering the entire salinity gradient from marine conditions at the mouth to nearly freshwater conditions upstream. The diversity of the samples and the distribution of the species along the main estuarine gradients were assessed. Hyperbenthic communities were identified using different multivariate statistical techniques. The species composition and the density and biomass of the dominant species of each community were compared among communities.

Meiobenthic distribution and nematode community structure in five European estuaries
Provedor de dados: 27
Autores: Soetaert, K.; Vincx, M.; Wittoeck, J.; Tulkens, M.
Meiofauna from the intertidal zone of five European estuaries (Ems, Westerschelde, Somme, Gironde, Tagus) was investigated. Samples represented a cross section of various benthic habitats from near-freshwater to marine, from pure silts to fine-sandy bottoms. The meiobenthic community comprised everywhere a fauna strongly dominated by nematodes, with meiobenthic density increasing with increasing salinity. The Ems differed from the other estuaries due to the presence of a well developed community of Copepods, Gastrotrichs, large Ciliates and/or soft-shelled Foraminiferans in some sites. The Westerschelde stood out due to the near-absence of harpacticoid copepods and, as in the Tagus, the lower meiobenthic densities in the marine part of the estuary. For...

Provedor de dados: 27
Autores: Mees, J.; Fockedey, N.
This note reports on the presence of a well established population of the isopod &lt;i&gt;Synidotea laevidorsalis&lt;/i&gt; (Miers) in the Gironde estuary (southwestern France). This species is new for the European fauna. &lt;i&gt;S. laevidorsalis&lt;/i&gt; is a nonendemic cool-temperate to subtropical, shallow-water species which was probably introduced into the study area from Asia. In the salinity range of 1 to 10 g l&lt;sup&gt;-1&lt;/sup&gt; of the Gironde the species constitutes an important component of the brackish-water hyperbenthic community. The population was already present in 1975 when it was misidentified as the native species &lt;i&gt;Idotea emarginata&lt;/i&gt; (Fabricius).

Fish assemblages of European tidal marshes: a comparison based on species, families and functional guilds
Provedor de dados: 27
Autores: Mathieson, S.; Cattrijsse, A.; Costa, M.J.; Drake, P.; Elliot, M.; Gardner, J.; Marchand, J.
In considering the use of estuarine habitats by fish assemblages, alternative views of the assemblage are increasingly being explored, based on functional rather than taxonomic aspects. The allocation of all taxa to a number of functional guilds allows a description of fish assemblages in terms of vertical zonation, habitat preferences, including the substratum preference of benthic/demersal species, and dietary preferences. This paper presents the first comparison of the structure of the fish assemblages in the tidal marshes of 6 European estuaries (Bay of Cadiz, Spain; Mira, Portugal; Loire, France; Westerschelde, The Netherlands; Humber, UK; Forth, UK). Cluster analysis was used to compare the assemblages recorded in 29 tidal marsh and associated...

&lt;i&gt;Fosliella farinosa&lt;/i&gt; (Lamour.) Howe var. &lt;i&gt;chalicodictya&lt;/i&gt; Taylor has been described in 1939 after material from the Caribbean Sea. It has never been mentioned since the &lt;i&gt;descriptio princeps&lt;/i&gt;. We found it sometimes while assorting phytosociological relevés from Banyuls and Port-Cros (France). &lt;i&gt;Lophosiphonia scopulorum&lt;/i&gt; (Harv.) Womersl., described from Australia, has recently been mentioned by Ardre (1970) along the Portuguese coasts. We noted this species at Banyuls. Both taxa are new for the Mediterranean Sea; the first one is new for the French algological flora.

Two new &lt;i&gt;Archilopsis&lt;/i&gt; species are described: &lt;i&gt;Archilopsis marifuga&lt;/i&gt; sp. n. and &lt;i&gt;Archilopsis arenaria&lt;/i&gt; sp. n.; &lt;i&gt;Archilopsis unipunctata&lt;/i&gt; (Fabricius, 1826) and &lt;i&gt;Archilopsis spinosa&lt;/i&gt; (Jensen, 1878) are redescribed. The latter taxon is re-established. The descriptions are based on morphological and karyological data. The four species of the genus can unequivocally be recognized by the morphology of the cirrus and the presence or absence of a stylet.The genus &lt;i&gt;Archilopsis&lt;/i&gt; is regarded as a monophyletic group with at least two autapomorphies. The relationship between the four species is discussed and a cladogram for the genus proposed. The existence of two...

Feeding of the hyperbenthic mysid &lt;i&gt;Neomysis integer&lt;/i&gt; in the maximum turbidity zone of the Elbe, Westerschelde and Gironde estuaries
Provedor de dados: 27
Autores: Fockedey, N.; Mees, J.
The diet of the mysid &lt;i&gt;Neomysis integer&lt;/i&gt;in the maximum turbidity zone (MTZ) of three European estuaries (Elbe, Westerschelde and Gironde) was investigated in spring 1993. The quality and quantity of the diet were assessed through measurement of the stomach fullness and microscopical analysis of the stomach content combined with image analyses. &lt;i&gt;N. integer&lt;/i&gt; was found to be an omnivore which mainly utilizes mesozooplankton and detritus carbon pools. The quality of the diet did not differ between the sexes or between different developmental stages, although smaller individuals consumed fewer items. In all three estuaries the diet was dominated by Copepoda Calanoida (5-10 &lt;i&gt;Eurytemora affinis&lt;/i&gt;...

Autores: Muylaert, K.; Sabbe, K.
In spring 1993 phytoplankton samples were taken along the longitudinal salinity gradient of the estuaries of the Elbe, Schelde and Gironde. A minimum in phytoplankton abundance, biomass and diversity was observed in the inner to upper reaches of all estuaries, suggesting massive mortality in these zones. Due to a combination of high turbidity and high river runoff, phytoplankton of the Gironde estuary differed in species composition and had lower cell abundancies and biomass compared with Elbe and Schelde. Phytoplankton structure and biomass of the polyhaline reaches of the Elbe and Schelde were quite comparable. They were characterized by the diatoms &lt;i&gt;Skeletonema costatum&lt;/i&gt; and several &lt;i&gt;Thalassiosira&lt;/i&gt; spp. and most...

Uptake of dissolved inorganic nitrogen in turbid, tidal estuaries
Provedor de dados: 27
Autores: Middelburg, J.J.; Nieuwenhuize, J.
Ammonium and nitrate uptake was measured in 6 European tidal estuaries (Ems, Rhine, Scheldt, Loire, Gironde and Douro) using &lt;sup&gt;15&lt;/sup&gt;N-tracer techniques. Uptake rates of ammonium and nitrate ranged from 0.005 to 1.56 µmol N l&lt;sup&gt;-1&lt;/sup&gt;h&lt;sup&gt;-1&lt;/sup&gt; and 0.00025 to 0.25 µmol N l&lt;sup&gt;-1&lt;/sup&gt; h&lt;sup&gt;-1&lt;/sup&gt;, respectively, and differed significantly between and within estuaries. Analysis of nitrogen uptake using the relative preferential index (RPI) indicated ammonium to be the preferred substrate. The turnover times of particulate nitrogen (0.7 to 31 d) and dissolved ammonium (0.1 to 27 d) were similar to or shorter than estuarine-water residence times, whereas turnover times of dissolved...

Provedor de dados: 27
Autores: Hecq, J.H.
The annual cycle of the Copepods, Cladocera, Appendicularians, Chaetognatha and Cnidaria has been observed in a coastal area in front of Boulogne-sur-Mer. Four species of Copepods amount to some 70% of the whole zooplankton. These herbivorous animals become especially abundant during the phytoplankton blooms with yield which seems to be more important during the autumn than during the spring. Yearly the Appendicularians offer four maxima agreeing with the transport of patches by the currents. The Chaetognatha are only present during the autumn. The cycle of Cladocera is described with respect to their fecundity. The Ctenaria show blooms succeeding those of herbivorous animals. The study of relations between the zooplankton trophic levels suggests that, in...

This paper evaluates the relevance of undertaking a Social Network Analysis (SNA) to better understand the role played by the network of actors during innovation processes as well as validate stakeholders’ views on actors’ relationships in a case study on the transition to organic farming in the Camargue territory (South of France). The SNA method is part of a set of methods that forms an approach that was developed to evaluate ex-post the impacts of agronomic research in the framework of the European research project IMPRESA.  The analysis particularly confirms, through the indicator of Betweenness, the growing role played by INRA (French National Institute of Agronomic Research) in the network and its contribution to the transition to organic...

Ernesto Genoni (1885-1975) pioneered biodynamic agriculture in Australia. In 1928 he was the first of (ultimately) twelve Australians to join Rudolf Steiner’s Experimental Circle of Anthroposophical Farmers and Gardeners (ECAFG) which was based at the Goetheanum, Dornach, Switzerland. Ernesto trained as an artist for five years at Milan’s prestigious Brera Academy. He visited his brothers in Australia, broad-acre immigrant farmers in Western Australia, in 1912 and 1914 and during these visits he worked on their, and other’s, farms. In 1916 he enlisted in the Australian Imperial Force (AIF) and served as a stretcher bearer on the battlefields of the Somme, France, before being conscripted into the Italian Army and serving jail-time in Italy as a draft...

In France, the research programmes have always been fairly decentralized. They are being carried out at several research institutions1 and universities. Government funding and sources of financing are available at national, regional and district level. Even at the national level, it is not easy to identify a real unified research policy. The main way to analyse the funding systems is to follow up the topics mentioned in the calls for proposals, which are often very much influenced by various policy networks.    During the last decades, farmers’ organisations have influenced the main themes of the research programmes, both at the National Institute for Agricultural Research (INRA) as well as at other institutions.  However, since the beginning of the 1990s,...

Invisible Farmer - Australia’s first woman organic farmer discovered in Switzerland: The story of Ileen Macpherson
Provedor de dados: 21
Autores: Paull, John.
On a hunch, I travelled from Oxford to the Swiss village of Dornach. Could it be that there were Australians who joined the world’s earliest organic agriculture research organisation back in the 1920s or 1930s? Then, I had never heard of Ileen Macpherson. I discovered in the archives of the Goetheanum that twelve Australians had joined Rudolf Steiner’s Experimental Circle. This is the story of one of those pioneers of organic farming, Ileen Macpherson (1898-1984). Ileen Macpherson was the daughter of a farming family. They farmed large pastoral properties in the south of New South Wales (NSW); Paika Station (250,000 acres) and later Goonambil Station, in the Murrumbidgee Valley. In 1934, Ileen, along with her partner Ernesto Genoni (1885-1974), founded...

Organic production (including agriculture, wild culture, forestry and aquaculture) is a worldwide phenomenon that is practiced in at least 172 countries. The Organics Olympiad presents 14 indices of global organics leadership, each at three levels (Gold, Silver and Bronze). The Organics Olympiad of 2016 yields 29 countries as global organics leaders, and confirms that organics leadership is diversely distributed across countries, large and small, rich and poor, developed and less so, and cuts across linguistic, ethnic and cultural boundaries. Australia continues to lead the world in organic agriculture hectares.

Rudolf Steiner delivered eight lectures at the Koberwitz Chateau (Schloss Koberwitz) in German in the summer of 1924 (7-16 June). There were 111 attendees, 30 women and 81 men, who came from six countries: Germany, Poland, Austria, Switzerland, France, and Sweden. The audience included farmers, estate managers, doctors, priests, teachers, artists, and engineers who all came to hear Steiner’s vision for agriculture. A witness observed “Seldom have I seen him so joyfully moved after the completion of a task as in this moment after the agricultural...

Autores: Casagrande, Marion; Alletto, Lionel; Naudin, Christophe; Seassau, Célia; Siah, Ali; Celette, Florian.
Enhancing plant-based diversity within agroecosystems may be an efficient way to achieve the objective of designing more resilient and low-input agricultural systems. The objectives of this study were (i) to describe the plant-based diversity practices implemented in organic or conventional agriculture in France and (ii) to identify the motivations of the farmers to apply such practices. It was also to compare the integration of such practices in organic or conventional farming systems. The survey was carried out in five French regions with 196 farmers that apply at least one plant-based diversification practice. Five diversification practices were studied: diversified crop rotations, use of catch crops, simultaneous intercropping, agroforestry and...

Autores: Diersen,   Matthew A.; Wilson,   William W.; Dahl,   Bruce L.; Satyanarayana,   Vidyashankara.
The value of credit guarantee programs has recently been called into question.  Credit guarantees are important marketing tools in the world wheat market, both to develop new markets and to compete in existing markets.  This study examines the additionality of export credit guarantees.  Empirical demand models were developed and estimated using pooled data among importing countries.  Models were estimated for each of the principal exporting countries providing export credit guarantees:  the United States, Canada and France.  Additionality of credit guarantees were also contrasted to the Export Enhancement Program.  Positive additionality was found for CCC guarantees, indicating that the GSM programs have resulted in additional exports that would not have...

Does Knowledge-Based Economy Speaks to Consumers? A French Case Study with Respect to Food Products
Provedor de dados: 31
Autores: Giraud,   Georges; Lebecque,   Annick; Amblard,   Corinne; Bord,   Cecile; Sulmont-Rosse,   Claire; Lefur,   Yves.
The paradigm of knowledge-based economy states that information asymmetry between consumers and producers will be reduced thanks to information availability and dissemination through the Internet or other media channels. Conversely to this statement, some published articles shown that knowledge-based economy reinforces the information asymmetry between experts and novices among the consumers (Hogg et al., 2007; Gregan-Paxton &amp; Roedder-John, 1997; Alba &amp; Hutchinson, 1987). Accordingly, we will consider the non homogeneity of consumers and will try to identify and qualify the differences between several groups of respondents regarding two food items by means of a k-means clustering applied to a knowledge-oriented questionnaire.

MODELLING IMPORT DEMAND SYSTEMS WITH NONSTATIONARY DATA: AN APPLICATION TO THE FRENCH IMPORTS OF VIRGIN OLIVE OIL
Provedor de dados: 31
Autores: Ben Kaabia,   Monia; Gil,   Jose Maria.
This paper aims to provide a flexible methodological framework to estimate import demand models, which explicitly considers the stochastic properties of data and the endogenous/exogenous nature of some variables. The French imports of virgin olive oil have been used as a case study with Spain, Italy and the Rest of the World as main suppliers. The methodological framework starts by the specification a reduced-form VAR. Appropriated exogeneity tests show the exogeneity of Total Real Imports, indicating the appropriateness of estimating a conditional model. Two cointegration relationships have been found. Several restrictions have been tested in order to identify them as AIDS equations. From structural coefficients of the restricted cointegrated vectors...

Price Transmission Asymmetries and Nonlinearities in the International Coffee Supply Chain
Provedor de dados: 31
Autores: Lee,   Jun; Gomez,   Miguel I.
We examine two distinct and important dimensions (e.g. symmetry vs. asymmetry and linearity vs. nonlinearity) of price transmission from international to retail coffee prices in France, Germany and the United States. We show that ignoring these two features of the price transmission process may lead to misleading impact assessments resulting from the elimination of International Coffee Agreement (ICA) in 1990. Our results confirm the presence of threshold effects in both periods (ICA and post ICA) in all three countries. Our estimates show that, in the long-run, the speed of adjustment toward equilibrium becomes faster during the post-ICA period in France and Germany. Our results suggest that, for these two countries, changes in international prices did...

Demand for seasonal wage labour in agriculture: what does family farming hide?
Provedor de dados: 31
Autores: Darpeix,   Aurelie; Bignebat,   Celine; Perrier-Cornet,   Philippe.
Seasonal wage labour was rarely distinguished from the permanent one in farm-household models although it has sharply increased in developed countries. Therefore, we propose to endogenize the demand for this peculiar labour type and highlight the trade-offs for the various labour combinations on farms. We use data on fruit and vegetables farms drawn from the 2000 French agricultural census. We show that seasonal wage labour is a substitute for permanent wage employment, and doesn't entirely follow the seasonality of the agricultural activity: competition on the labour and product markets play a significant role in the employment of labour types.

Technical efficiency and technology in Eastern and Western agriculture: A comparison of crop and dairy farms in Hungary and France
Provedor de dados: 31
Autores: Fogarasi,   Jozsef; Latruffe,   Laure.
The paper investigates the difference in technical efficiency and technology between French and Hungarian farms in dairy and cereal, oilseed and protein seed (COP) sectors during 2001-2004. The analyses is performed with Data Envelopment Analysis (DEA) under separate and common frontiers. Results indicate that Hungarian dairy farmers are more clustered to their own frontier than French farms are, but that the difference is less clear in COP farming. Hungarian dairy and COP farms are less scale efficient than French farms on average. Under a common hypothetical technology, Hungarian farms would be the leaders. Reasons might be the presence of large corporate farms and a higher public support in Hungary.

Converting to organic farming in France: Is there a selection problem?
Provedor de dados: 31
Autores: Latruffe,   Laure; Nauges,   Celine.
Using a sample of French crop farms during the 1999-2006 period, we test whether less technically efficient farmers are more likely to engage in organic farming in order to benefit from conversion subsidies. Despite some limitations in our data, we find no evidence of such selection effect. On the contrary, our estimation results indicate that more technically efficient farmers are more likely to convert to organic farming. This finding is found to be robust to the method of calculation of efficiency scores, either parametric or non-parametric. This study also confirms that farm’s characteristics (education, farm size and legal status) and farmers’ practices under conventional farming do impact the probability of conversion to OF.

Direct payments, crop insurance and the volatility of farm income. Some evidence in France and in Italy
Provedor de dados: 31
Autores: Enjolras,   Geoffroy; Capitanio,   Fabian; Aubert,   Magali; Adinolfi,   Felice.
Volatility of farm income represents a major challenge for farm management and the design of public policies. This paper measures the extent to which risk management tools, especially direct payments and crop insurance, can significantly reduce crop income volatility in France and in Italy. We use an original dataset of 9,555 farms for the period 2003-2007 drawn up from the Farm Accountancy Data Network (FADN) and three different econometric models to explain the volatility of crop income. The results are contrasted between the specialization of the farms and the two countries: Italian farms use management tools (CAP payments and crop insurance) so as to improve their income and to reduce its volatility (crop insurance, inputs). French farms use the same...

Impact of CAP Direct Payments on French Farms’ Managerial Efficiency
Provedor de dados: 31
Autores: Latruffe,   Laure; Guyomard,   Herve; Le Mouel,   Chantal.
This paper investigates the relationship between CAP direct payments and managerial efficiency for French crop and beef farms. Managerial efficiency scores are calculated using a four-step approach that allows to disentangle managerial inefficiency from other technical inefficiency components, notably what is due to unfavourable environment conditions. Then managerial efficiency scores are regressed over a set of explanatory variables, including CAP direct payments. Our empirical application, based on individual farm data and meteorological data at the municipality level for the year 2000, shows that there is a substantial component of inefficiency that is due to unfavourable conditions. Moreover, there is a significant negative relationship between...

A Multidimensional Homo Economicus: Cultural Dimensions of Economic Preferences in Four Countries
Provedor de dados: 31
Autores: Ehmke,   Mariah D.; Lusk,   Jayson L.; Tyner,   Wallace E.
Previous work in experimental economics reveals specific differences in economic behavior, especially reciprocity and free-riding behavior, across cultures.  We expand the possible pallet of cross-cultural behavioral differences that may exist. We hypothesize that different kinds of strategic interaction and individual decision-making behaviors differ across locations. The variety of experiments we use allow us to report multidimensional rather than just single dimensional differences in behavior across locations. In order to build a broad Homo Economicus we conducted economic experiments in four dissimilar locations: Hangzhou, China; Niamey, Niger; Grenoble, France; Manhattan, Kansas; and West Lafayette, Indiana.  Each subject completed an ultimatum...

Energy Crop Supply in France: A Min-Max Regret Approach
Provedor de dados: 31
Autores: Kazakci,   Akin; Rozakis,   Stelios.
This paper attempts to estimate energy crop supply using an LP model comprising hundreds of representative farms of the arable cropping sector in France. In order to enhance the predictive ability of such a model and to provide an analytical tool useful to policy makers, interval linear programming (ILP) is used to formalise bounded rationality conditions. In the presence of uncertainty related to yields and prices it is assumed that the farmer minimises the distance from optimality once uncertainty resolves introducing an alternative criterion to the classic profit maximisation rationale. Model validation based on observed activity levels suggests that about 40% of the farms adopt the min-max regret criterion. Then energy crop supply curves, generated by...

Impacts of the French bio-fuel policy on the French arable crop sub-sector
Provedor de dados: 31
Autores: Guinde,   Loic; Jacquet,   Florence; Millet,   Guy.
The paper provides an analysis of the impacts of the biofuel policy on the French arable crop sub-sector. The model used is a biofuel supply model composed of an agricultural module and an industrial biofuel processing module. The agricultural supply model is an aggregation of 1094 farm models, based on data from the French Farm Accountancy Data Network (FADN). Different biofuel chains are included in the model: ethanol from wheat and sugar beet, biodiesel (Vegetable Oil Methyl Ester) from rapeseed and sunflower. Scenarios are built upon the recent policy of an increased demand of biofuels for the next years, under the assumption of fulfilling the targets with domestic production only. Results show that the incorporation target of 7% of biofuels in...

Could small dairy farms in Switzerland compete with their French counterparts? A metafrontier analysis during 1990-2004
Provedor de dados: 31
Autores: Ferjani,   Ali; Latruffe,   Laure.
The objective of the paper is to investigate whether Swiss farms specialised in dairy (the prevailing production of the country), which are small in international standards, would have a survival potential if they had to compete more directly with EU farms. More specifically, we investigate whether Swiss dairy farms would be able to compete with their French counterparts (located in mountainous areas, but larger than Swiss ones) in a future made of increased globalisation and reduced borders. For this we evaluate which country, during the period 1990-2004, would have been more able to use efficiently a common hypothetical technology, and would have had a more productive (own) technology. Efficiency scores and technology ratios are calculated using the...

How do agricultural policies influence farmland concentration? The example of France
Provedor de dados: 31
Autores: Piet,   Laurent; Desjeux,   Yann; Latruffe,   Laure; Le Mouel,   Chantal.
Over the last decades, the number of farms has decreased while average farm size has increased in industrialised countries. We investigate whether these two concomitant trends have resulted in higher farmland concentration or not in the case of France. Deriving Gini coefficients as a measure of concentration from the estimation of parametric Lorenz curves, we show that this is not systematically the case at the sub-national scale of “départements”. When studying the role of possible explanatory variables for farmland concentration, we find that milk quotas, CAP 2nd pillar subsidies and so-called structural measures (settlements and early retirement grants) have a significant impact. However, the availability and the price of agricultural land appear to be...

Farm Structure and the Effects of Agri-Environmental Programs: Results from a Matching Analysis for European Countries
Provedor de dados: 31
Autores: Pufahl,   Andrea; Weiss,   Christoph R.
This paper extends previous research (Pufahl and Weiss, 2009) and applies a semi-parametric propensity score matching approach to evaluate the effects of agrienvironment (AE) programs on input use and farm output of individual farms in eight Member States of the European Union. We find substantial differences in treatment effects between countries. The analysis reveals significant effects of AE participation on production (Germany, France) and farm profits (France, Ireland, United Kingdom). AE participation sporadically reduces the intensity of land use as measured by the purchase of farm chemicals (fertilizer, pesticide) and grazing livestock densities. We also find differences in the treatment effect among farms with different farm size (heterogeneous...

Agrarpolitische Interessen Frankreichs und Deutschlands – Gemeinsamkeiten und Divergenzen unter sich ändernden Rahmenbedingungen

The aim of this contribution is to examine how the French and the German positions on agricultural policy have developed since the foundation of the EEC and what the driving forces were behind. The “general consensus” underlying the EEC treaty, and according to which the common market would be “conquered” by France in the case of the classical agricultural products, could not be translated into practice; for what emerged for these products was not a customs union but a “price support union”. As a consequence French intra-community agricultural exports had to be redirected to the world market. Thus initial positive French income transfers via intracommunity trade were transformed into transfers from the EC budget, an evolution that can be interpreted as a...

The Determinants of the Very Highest Income Shares: The Case of France
Provedor de dados: 31
Autores: DiPietro,   William R.; Anoruo,   Emmanuel; Sawhney,   Bansi.
Since the highest income groups have tremendous influence over economic policy by virtue of money, position, and connection, it is important to identify the interest of these groups with regard to economic conditions. Recently, annual time series data on the shares of the very highest income groups have become available for the French economy. Using this new high-income share data for France, this paper examines the potential relationship between the income shares of the very highest income groups and four macroeconomic variables including the inflation rate, the interest rate, the unemployment rate, and the extent of trade. To be specific, this paper investigates the extent to which the four macroeconomic variables affect the highest income shares. The...

The paper investigates the difference in technical efficiency and potential technology gap between French and Hungarian dairy farms during 2001-2006, using Data Envelopment Analysis under each country’s respective frontier and under a common frontier (metafrontier). Results indicate that French farms have a more optimal scale of production than Hungarian farms, but Hungarian farms make better use of the technology. They also have a more productive technology than French farms. The latter finding is obtained under the assumption of a hypothetical common frontier. Although French and Hungarian farmers do not have access to the same technologies and the metafrontier is still hypothetical, our paper adds to the thin literature that compares two countries in...

Irreversibility, Uncertainty and the Adoption of Transgenic Crops: the Case of BT-Maize in France
Provedor de dados: 31
Autores: Scatasta,   Sara; Wesseler,   Justus; Demont,   Matty.
This study applies a real option approach to quantify, ex-ante, the maximum incremental social tolerable irreversible costs that would justify immediate adoption of Bt maize in France. Based on field trials, we find that incremental private reversible benefits in the agricultural sector are -18 million euro yearly for maize for animal feed and 1 million euro yearly for maize for human consumption. Incremental social irreversible benefits from reduced insecticide use are negligible. The maximum incremental social tolerable irreversible costs are -28 million euro yearly for maize for animal feed and 0.4 million Euro yearly for maize for human consumption.

The diversity of the V3 loop tip motif sequences of HIV-1 subtype B was analyzed in patients from Botucatu (Brazil) and Montpellier (France). Overall, 37 tetrameric tip motifs were identified, 28 and 17 of them being recognized in Brazilian and French patients, respectively. The GPGR (P) motif was predominant in French but not in Brazilian patients (53.5% vs 31.0%), whereas the GWGR (W) motif was frequent in Brazilian patients (23.0%) and absent in French patients. Three tip motif groups were considered: P, W, and non-P non-W groups. The distribution of HIV-1 isolates into the three groups was significantly different between isolates from Botucatu and from Montpellier (P &lt; 0.001). A higher proportion of CXCR4-using HIV-1 (X4 variants) was observed in...
