Le Bassin ostréicole de Marennes-Oléron, et globalement la Charente-Maritime, sont marqués depuis les années 80 (Héral, 1986), par un net recul des rendements de production qui engendrent une diminution de la rentabilité économique et un accroissement des coûts de production. La démonstration de la surcharge biologique du Bassin de Marennes-Oléron est faite depuis 1985. Cette situation a évolué depuis cette date, par une diminution des cheptels en  élevage et par une augmentation des cheptels sauvages ce qui a abouti à des plans d'entretien et de restructuration du DPM. Cependant, la situation défavorable pour la majorité des zones charentaises en terme de croissance-production est annuellement confirmée, depuis 1993 au moyen des réseaux de croissance...

Assessment and interpretation of temporal or spactial differences in shellfish productivity of typical French ecosystems
Provedor de dados: 5
Autores: Mazurie, Joseph; Soletchnik, Patrick; Ropert, Michel; Fleury, Pierre-gildas; Auby, Isabelle; Maurer, Daniele; Bacher, Cedric.
Monitoring of Crassostrea gigas performances, from two year-classes, during 12 years, in various French shellfish farming areas have revealed great inter-annual and inter-sites differences in reproduction, growth, mortality or quality of oysters (meat content, Polydora infestation...). The presentation attempts to highlight how a comparative analysis of existing temporal or spatial data on molluscs, water quality, geography or meteorogoly may help to better understand and manage shellfish ecosystems. The range of hydrobiological conditions (food availability, turbidity, temperature...) recorded at national, pluriannual scale, in relation to shellfish performances, enlarges the base of such relationship. However, undirect causative factors, either natural...

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...

Relationships between oyster mortality patterns and environmental data from monitoring databases along the coasts of France
Provedor de dados: 5
Autores: Soletchnik, Patrick; Ropert, Michel; Mazurie, Joseph; Fleury, Pierre-gildas; Le Coz, Florence.
Oyster mortality was monitored at multiple sites along the French coastline (around 5 500 km) between 1993 and 2005. Mortality data for one- and two-year-old oysters were collected over 10–12 years in 39 oyster culture sites bordering 3 different "seas": the English Channel, Bay of Biscaye and Mediterranean. Combining these data with records from environmental monitoring databases, 11 of these sites had consistent chronological data sets including both environmental data and mortality records. Mortality in one-year-old oysters was clearly summer mortality (49% of their annual mortality) whereas mortality of two-year-olds occurred mostly in spring (51%). Analysis of variance revealed that "coastal area" was the main influence on mortality of one-year-olds...

Les contraintes et les perspectives de développement de l'élevage de la coquille Saint-Jacques en France
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Paquotte, Philippe.
L'élevage des Pectinidés (famille des pétoncles et coquilles Saint-Jacques) a connu dans le monde quelques développements spectaculaires : Japon, Chine, Nouvelle-Zélande, Tasmanie (Dao, 1997). En France, des efforts importants en matière de recherche et développement ont été portés sur cet élevage : 2 contrats de plan Etat-région Bretagne (Dao et al. 1994), le contrat de baie Rade de Brest (Dao et al. 1996) et une action concertée européenne (Fleury et al. 1997). Mais la production reste encore marginale (100-150 t /an).

This study is the second part of a former report rapport Ifremer DRV/RST/RA/LCB/2002-08 dealing with rearing methods, growth and mortality performances, and problems encountered by the oyster farmers from Quiberon Bay (2800 ha of leases) : the first report relied on a survey achieved in july 200l, about 18 oyster farmers, and 2 diving campaigns (july and october 2001) on 2 years old oyster batches from the same farmers. Il is now completed by a last campaign of diving in october 2002, on 7 parcels out of the 18, still bearing the initial oysters. The analysed enterprises vary in particular by the location and depth of their concession inside the bay, but also by their rearing scheme : a majority favours seedings with 18 month old oysters or more, according...

Marine protected areas are a laboratory of integrated coastal management. Driving the MPA system requires the implementation of a battery of indicators of governance. This governance must take into account both the internal dynamics of the system and the threats coming from the system environment. As part of a research project funded by the French Ministry of Ecology, (Liteau program), 4 coral reef MPAs were selected as pilote studies (St Martin in the Caribbean, Reunion and Mayotte in the Indian Ocean, the South Lagoon of New Caledonia in Oceania) to develop jointly between scientists and managers of MPAs governance indicators. The approach is definitely bottom up. It is based on the co-construction of indicators. In that way, the views of the scientists...

Autores: Fleury, Pierre-gildas; Claude, Serge; Bouget, Jean-francois; Langlade, Aime; Le Coguic, Yvette.
Every year, from March to December, the IFREMER / REMORA network carries out a survey of mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year ciass ; and "adults" = two-years class), distributed among various stations of the main French oyster areas. In Brittany, this network includes 11 points, to which regional points can be added (15 in 2000). With regard to the Breton stations of the network, the year 2000 showed rather low mortality rates, excepted mortality of several oysters when transfered to the sea. Several areas however had higher mortality rates (&gt; 20%) : l'Arguenon, Morlaix, les Abers, Pen-Bé and Le Croisic. 2000 is a year of good growth in South Brittany (72.8 g in December), more average in North Brittany...

Effect of sediment nearness on the metabolic enzyme activity and energy state of the oyster Crassostrea gigas
Provedor de dados: 5
Autores: Le Moullac, Gilles; Fleury, Pierre-gildas; Le Coz, Jean-rene; Moal, Jeanne; Samain, Jean-francois.
This study was designed to assess in situ the effects of sediment nearness on Crassostrea gigas metabolism. One year-old oysters were reared for 5 months (April-August) in plastic bags on metallic frames at 10 and 60 cm off the sediment at the beginning of April. The management of the energetic resources (storage, consumption) was estimated with respect to biochemical changes of proteins, lipids and carbohydrates. In order to evaluate the  effect of the sediment nearness at cellular level, the metabolic rate was evaluated by assessing pyruvate kinase (PK) and phosphoenolpyruvate carboxykinase (PEPCK) enzyme activities and electron transport system (ETS) activity. The metabolic pathways were assessed by measuring ATP and intermediary metabolites such as...

Etude sanitaire (1984-1986) de la rivière de Pénerf (Morbihan)
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Chauvin, Jacky.
La plus grande partie des marais de la rivière de Pénerf a été classée insalubre en 1941. Il importait d'en revoir le classement au vu des normes de salubrité précises (définies seulement depuis 1976) et parce que leur potentiel aquacole parait de plus en plus intéressant. Malgré quelques signes d’alarme la salubrité de la rivière est globalement acceptable. Les zones insalubres elles-mêmes, bien que légèrement hors normes, ne paraissent pas d'une qualité rédhibitoires pour l'élevage de coquillages si l'on admet que ceux-ci peuvent être décontaminés ensuite par reparcage en zone salubre (contaminations non irrémédiables). Enfin le marais de Saint-Guérin pour lequel il existe des projets de claires d'affinage, apparaît tout à fait conforme et serait donc à...

La Petite Mer de Gavres est une zone conchylicole, classée salubre, et exploitée en pêche à pied, avec une commercialisation directe difficile à contrôler. A la suite de problèmes de salubrité rencontrés sur les coquillages de cette zone, une étude bactériologique a été réalisée par IFREMER de juin 1986 à septembre 1987, suivie en 1988 d'une comparaison des contaminations des différentes espèces de coquillages. Ces études montrent que l'insalubrité de certains coquillages de la petite Mer de Gavres est particulièrement évidente pour les fouisseurs (coques et palourdes). Malgré la proximité des sources de pollutions de la Rade de Lorient et la petitesse du bassin versant de la Petite Mer, c'est ce dernier qui la contamine, notamment aux abords du bourg de...

The article is an excerpt from a focus document for understand scallop aquafarming's position. Studies on this species are part of IFREMER/DRV research programmes as an aquafarming as well as a halieutic resource. They are currently becoming reality through significant support for fishing management but also through experiments of semis of juveniles at various English Channel and Atlantic sites, to cite only the most applied operations. Fishing and shellfish farming professionals are closely associated with this programme. Scallop fishing occupies a prominent position this year in the press by reason of fishing and marketing problems due to intake being much higher than in past years. The situation matches the forecasts of IFREMER teams that have been...

Autores: Paquotte, Philippe; Fleury, Pierre-gildas.
(Not controled OCR) The French King scallop farming method (hatchery, intermediate culture in cages nnd sea-bed extensive ongrowing) has been developed since 1983. A multi-steps project analysis has been carried out to estimate the economic feasability of the rearing activity. Because there is no market for spat in France at the moment, the project concerns the whole production cycle from hatchery to harvest. The project is designed to supply 150 m.t. of maketable scallops, which is the expected French farmed production in the near future. The project analysis software developed by IFREMER provides the main financial criteria, i.e. internal rate of return, potential earning power, cash requirements and a breakdown of the production costs.

Summer mortalities of young oysters have been studied in 1999 through the monitoring of a unique oyster batch distributed among 3 sites located from upstream of an estuary (Fort-Espagnol, Auray river) to downstream (Kerpenhir, Auray river) up to open bay (Men er Roué, Bay of Quiberon). Mortality and growth have been monitered in parallel with vitality indices, so as to try or identify periods of weakness of oysters. The spat grew from a mean weight of 3 g, in the beginning of May to around 35 g in November, without sharp differences between sites. The summer mortalities remained moderate (10 %) in the 2 most marine stations, whereas a light peak of mortality (15 %) was recorded in July in the most continental station. Any of the physico-chemical parameters...

Mussel samples have been placed in plastic-mesh bags hung on wood poles (« bouchots »), at 4 locations of a mussel culture area in the bay of Vilaine (South Brittany, France). They have been monitored for one year, from February 2000 to February 2001. The recorded growth have been rather fast (plus 1.2 g per month between April and September), and mortalities moderate (between 15% to 25%), with better results in southern stations, further from the estuary.  Among the physico-chemical parameters recorded, the most striking were very low salinities (below 10 g/l) recorded for days, after heavy rains. They provoqued a valve closure of mussels (recorded by a « valvometer »). Some physiological indicators being tested (muscle force and hermeticity) seemed to...

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, and with comparison to previous years, 1999 exhibited mortality in adults (23%) and poor growth in both adults (63.0 g in late November) and...

Aquaculture production of scallop has been identified by a series of technical operations during the past ten years programme under a partnership involving the fishermen organizations with regional and national grants. 3 million juveniles have been produced annually, giving a potential recapture by fishing of 100 to 120 tonnes 3 years later. Results in terms of technical and economical approach have pointed out the principal unknown factors responsable for high costs. 7he pilot programme aims to increase the production to reach a level of 5 million juveniles to support the fishery of the rade de Brest and induce new management of the resources. Two priorities were selected, control of the reproduction in the hatchery to obtain reliable larval and...

Bi-parental families were produced in hatchery and tested in the field in 2001. Two sets of 5 families were constituted, selected on their high (R) and low (S) survival. These two sets were reared in Brittany from March to November 2002. Samplings were performed twice a month to obtain data on biometry, survival, reproductive cycle, biochemical composition, adenylate energy charge, hemolymph parameters (ions and defense system) and muscle strength. "R" and "S" oysters exhibited different reproductive effort and spawning strategy. "R" oysters allocated less energy in gonad than "S" ones and presented a complete spawning at the end of August contrary to the "S" which spawns partially. Mortality started in July when the seawater temperature reached 19 degree...

A preliminary study of the behaviour and vitality of reseeded juvenile great scallops, of three sizes in three seasons
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Mingant, Christian; Castillo, A.
In order to have a better understanding of recessing in great scallop, Pecten maximus and consequently the causes of mortality at reseeding, this study has monitored, at different seasons, the dispersion and recessing of different sizes of juveniles (about 15, 30 and 45 mm, called small, medium and large) after seeding. Moreover, the aim was to see when small spat (15 mm) could be seeded, and thus reduce the costs of intermediate culture. Three monitoring approaches were used together: (1) continual observations by remote video camera, of a defined area (less than 1 m2) containing 10 scallops from each size group; (2) daily monitoring of behaviour with divers along three bottom lines, with 20 × 1 m2 plots each and nine marked scallops per plot; and (3) the...

The wide range of data from the French Ifremer/REMORA network, collected since 1993 allow a global characterization of mortalities of 1-year old and 2-years old cupped oysters Crassostrea gigas, that are cultivated in the main French oyster areas (Fleury et al, 2003), and thus a better understanding of the causes of these mortalities (Ifremer /MOREST project).  The average annual mortalities on intertidal sites range from 10 to 20%. Most of the mortalities take place in Spring and Summer. 1-year oyster mortalities occur in Marennes and several sites in Brittany whilst 2-years oyster mortalities occur in the same sites and in baie des Veys (Normandy). In addition, 2-years oyster mortalities appear more variable according to different annual surveys....

Autores: Maguire, Julie A.; Fleury, Pierre-gildas; Burnell, Gavin M.
(Not controled OCR) Because biological systems do not work in isolation, behavioral, biochemical, and physiological tests can give an overview of an individual's vital processes and reaction to stress. Two stress gradients were applied in this study, a short acute desiccation stress and a long-term density stress. These stress gradients were used to assess the usefulness of various techniques for quality assessment: namely, a standard salinity stress test, condition index, recessing speed of the scallop, adenylic energetic charge (AEC). and percentage carbohydrate content of the striated muscle. The results showed that AEC could be used effectively to measure the effect of a short-term stress. In the striated muscle. AEC levels were useful in...

Reconnus dans toute la zone intertropicale comme outils d'aménagement incontournables des petites pêches côtières, les DCP (Dispositifs de Concentration de Poissons) ont été implantés autour de La Réunion à partir de 1988 et gérés collectivement par le Comité Régional des Pêches. Ces DCP côtiers, ancrés à quelques milles des ports de pêche ont permis un redéploiement d'une grande partie de l'effort de pêche vers les espèces pélagiques du large, diminuant ainsi la pression exercée sur les espèces récifales côtières. La présente étude a pour objectifs de mettre à jour les connaissances techniques et économiques sur le "système DCP", autour des pêcheurs, de la pêche sur DCP et des DCP eux-mêmes. Une enquête des usages et des perceptions des pêcheurs vis-à-vis...

Marine Protected Areas (MPA) have turned to be a privileged tool for sustainable management of coastal areas and associated activities. But MPA's results for biodiversity and sustainable fisheries have to be assessed. That is the aim of PAMPA project, which is built on the experience of 7 French MPAs in the Mediterranean sea and in the overseas territories.  In this PAMPA project, Ifremer Océan Indien has mainly been involved in the analysis of fisheries data and opinion surveys, conducted from July to October 2010, towards fishermen on board around the coral reef. About sixty fishermen have been interviewed. Only two of them denied answering.  Recreational fishers are "local people", about forty or fifty years old, regularly at sea, but without fishing...

L'aquaculture et la pêche ne font pas toujours bon ménage : conflit pour les zones de production (élevages en mer), concurrence sur le marché (poisson d'élevage / poisson "sauvage"), et surtout conflit sur la gestion des stocks naturels de juvéniles, parfois exploités pour l'approvisionnement des élevages au détriment d'une production naturelle d'adultes pour le stock exploité par pêche (palourde du golfe du Morbihan, crevettes tropicales, etc).  En d'autres cas les techniques d'élevage peuvent se révéler au contraire un outil précieux pour la gestion des stocks naturels, particulièrement pour des animaux plus ou moins sédentaires comme les Mollusques ou les Crustacés. Ici l'élevage des juvéniles va permettre de conforter le stock naturel des animaux...

In the aim of diversification for small fisheries, a survey has been conducted in 2000 by the Regional Fisheries Committee and the French Institute for Exploitation of the Sea (Ifremer) between 200 and 600 m deep, in the West of Reunion Island. Potential commercial fish stocks have been found out. Numerous professional and recreational fishermen have bought equipment in order to exploit this resource (electric winches). But deep demersal fish is a fragile resource due mainly to low growth and late sexual maturation. Face to this increasing pressure upon a fragile resource, a new survey has been carried out by Ifremer in 2011, with use of the same fishing sites, material and method than in 2000. Results displayed in this report are compared to those of...

La question des mortalités estivales de naissains d'huîtres creuses en baie de Quiberon a été abordée selon deux approches complémentaires, l'une plus temporelle, avec le suivi estival régulier de quelques semis, l'autre plus spatiale avec une estimation en plongée des survies en fin d'été d'un plus grand nombre de semis répartis à travers la baie. Le suivi de l'évolution des semis a permis de dater et de quantifier les mortalités estivales sur plusieurs périodes (juin et août essentiellement) ; mais il n'a pas permis d'en identifier les causes. Le rôle des pathogènes, notamment, n'est pas défini. Par ailleurs, l'estimation spatiale des mortalités en fin d'été met en évidence des mortalités nettement différenciées entre les semis (entre 6 et 48%). Parmi...

The recent creation of the Réserve Naturelle Marine (Natural Marine Reserve) of La Réunion (RNMR) island in 2007 has provided a legal status to the traditional coastal fisheries and to the spear-fishing operating on the coral reef habitat. This legal frame implies fisheries surveillance and patrolling along with scientific surveys and monitoring, such as the "PechTrad" collaborative project, lead jointly by the RNMR and the French Research Institute for Exploration of the Sea (Ifremer). Four types of fisheries are allowed with specific regulation on the coral reef ecosystem and are analysed here after a 4-year survey (2008-2011): the beach seine targeting the yellowstripe goatfish (Mulloidichthys flavolineatus), the octopus shallow water collecting, the...

The network IFREMER/REMORA has watched every year, since 1993, from February to December, mortality, growth and quality criteria of two oyster class-size ("juveniles" of the first-year c1ass and "adults" of the second year c1ass), distributed among various stations of the French oyster areas. This has provided a quite standard and simple annual assessment of the rearing results, generally tallied with professional observations. From year to year, data series have been obtained, from which mean values (references), chronological trends or spatial differences can be analysed. Results in Brittany, from 1993 to 1998, show that, in a "normal" year, 30 g oysters grow to 60-80 g at the end of the year, with a mortality rate of 10-15%. Mortality occures mainly in...

Force production during escape responses: sequential recruitment of the phasic and tonic portions of the adductor muscle in juvenile sea scallop, Placopecten Magellanicus (gmelin)
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Janssoone, Xavier; Nadeau, Madeleine; Guderley, Helga.
Giant scallops, Placopecten magellanicus, respond to the presence of starfish predators with an escape response consisting of a series of rapid valve adductions that allow the scallop to jump or swim away from the predator. To evaluate the coordination of the activity of the tonic and phasic muscles during such escape responses, we recorded their force production by attaching a force gauge to the shell of intact scallops and then stimulating the scallops with starfish.

Les coûts de production dans la filière d'élevage de coquille Saint-Jacques
Provedor de dados: 5
Autores: Paquotte, Philippe; Fleury, Pierre-gildas.
The development of king scallop (Pecten maximus) culture in France has been subsidised by the State and the Brittany Region for the past 10 years. Technical progress has been made and the public authorities now wish to know if this activity is economically feasible. While continuing research to improve the performance of this type of shellfish culture (culture techniques and physiology), Ifremer (public institute for oceanological research) also undertook an economic assessment on costs, marketability and legal and social limitations. The study of the costs of production presented here was carried out by analysing a pilot farm. This approach helped detail the financial needs and the degree of profitability of scallop farming.

De la pêche à l'aquaculture : l'élevage de la coquille Saint-Jacques
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Dao, Jean-claude.
The scallop is a filtering mollusc that feeds predominantly on phytoplankton. It lives on loose beds of maerl, sand or mud, most often between 5 and 40 metres deep. The scallop likes cool (7° to 20°C) and well oxygenated ocean waters. It does not tolerate desalination or emersion out of water. In France, there are two very closely related species: Pecten maximus in the English Channel and the Atlantic and Pecten jacobaeus in the Mediterranean. These are frequent species in French coastal waters. But the many deposits, considerably exploited, have rather thinned out over the last 20 or 30 years.

Synthèse de l'étude et des campagnes à la mer 2011 sur l'exploitation aux vire-lignes des espèces démersales profondes autour de La Réunion
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Evano, Hugues; Le Ru, Loic; Aureche, Vincent.
In an effort to implement new fishing activities for the small scale fisheries of Reunion Island, a prospecting cruise targeting deep demersal fish (200 to 600 m) was set up on the west coast of Reunion Island in 2000. This project was carried out by the Regional Fishery Committee and the French Institute for the Exploration of the Sea (Ifremer). Large commercial stocks were identified, and numerous professional or recreational fishermen started employing electric winches to exploit these deep resources.  However, the deep demersal species are a fragile resource due mainly to low growth rates and late sexual maturation. Due to the rapid increase in fishing pressure, Ifremer was asked to set up a new study and two scientific campaigns were carried out in...

Campagne de prospection de poissons démersaux profonds réalisée autour de La Réunion en 2011
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Evano, Hugues; Le Ru, Loic.
Since 2000, the exploitation of the deep demersal fish (200-700 m) with the use of electric winches has been increasing in Reunion island ; and this has needed a new appraisal of yields (CPUE) and individual fish sizes, as indicators of the state of the fish stocks. A first survey has been carried out at the first half of 2011, in order to set up the comparison with a previous survey in 2000 on the West coast of Reunion island. Drops of yields and sizes could be pointed out, attesting the overexploitation of the commercial species (Fleury et al 2011). This present report displays the results of a second campaign, carried out in the second half of 2011 all around the island. 32 fishing trips have been conducted which have permitted 251 fishing operations....

Scallop Sea Bed Culture in Europe
Provedor de dados: 5
Autores: Dao, Jean-claude; Fleury, Pierre-gildas; Barret, Jean.
(Not controled OCR) In recent years, scallop production throughout the world has been expanding at a fast rate, due to developments in aquaculture. Hanging as well as sea bed cultures produced good results in some countries. This latter method has been successful for Patinopeeten ye.ssoen.sis and Pecien novaezelandiae in Japan and New Zealand respectively. In Europe, only Peeten ma.ximus as a local species seems appropriate for development by a sea ranching production: the market demand is strong, the fisheries are closed due to over exploitation and hanging cultures are not economically feasible. Experiments in sea bed cultures started in the 1980s in France and extended to Ireland, Scotland and Norway. The technique involves the production of juveniles...

Le risque sédimentaire

The "sedimentary risk" has been identified since the mid-nineties in the Marennes Oléron Bay. The proximity of the sediment (from 0 to 15cms) increases the mortality rate. Depending on the year, mortality can be 10 to 20 % higher than in "high" conditions (50 to 70cms). These zootechnic results, gathered since 1996 on the working site of Ronces – Perquis, lead to the research of a pathogenic agent or a toxic substance released by the sediment. Studies conducted between 2002 and 2003 [12, 18] did not allow the identification of any pathogenic agents and ruled out the infectious risk. In 2004, the chemical risk (sulphides, ammoniacal nitrogen) was studied on 4 sites (3 working sites + Quiberon). In 2004, the "on-bottom/off bottom" mortality model of the...

Le choix d'un site de semis de coquilles Saint-Jacques : le littoral Ouest-Cotentin
Provedor de dados: 5
Autores: Fleury, Pierre-gildas.
La coquille Saint-Jacques est un mollusque filtreur au comportement spécifique. Ceci confère à son élevage des contraintes particulières. Une étude de site est donc nécessaire avant tout essai d'aquaculture extensive. Elle consiste d'abord à examiner les facteurs naturels et socio-économiques de la zone prospectée, en soulignant leurs intérêts ou inconvénients à l'égard d'un semis éventuel de Coquilles Saint-Jacques. Pour le choix d'un site de semis, on confronte ensuite des critères de sélection aux aptitudes des différents secteurs. La sélection peut se faire, par élimination ou par comparaison, les deux méthodes étant complémentaires. La côte Ouest du Cotentin a été ainsi étudiée. Le secteur qui paraît le mieux convenir serait celui entre les Nattes et...

The network IFREMER/ REMORA watches every year, from February to December, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year class ; and "adults" = two-years class), distributed 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 regarded as an accurate estimation of professional oyster ongrowings. With regard to REMORA results, generally tallied with professional observations, 1998 on the whole was a second year of low mortality. But some areas remained affected by significant mortalities such as Pen-Bé in South Brittany. The year 1998 was overall a very poor year for growth : the mean oyster weight in...

The objectives of marine protected areas (MPA), such as Reunion’s Marine Reserve founded in 2007, are (i) protect habitats (ecosystems) and resources (biodiversity) from increasing pressure due to a major urban, economic and recreational development; ii) manage uses and conflicts between traditional fisheries, spear-fishing, diving and recreational activities inside the coastal zone. These goals necessitate monitoring tools such as indicators and diagnostics. The PAMPA programme involves seven MPA including the Natural Marine Reserve of La Reunion (RNMR). It aims for each site to identify and validate indicators according to management objectives and group them in a MPA performance dashboard. This panel will help to visualize temporal trends and define...

Le réseau de veille zoosanitaire des mollusques, REPAMO, a été créé en 1992 afin de protéger les espèces d'intérêt économique des maladies susceptibles de les affecter. En effet, de même que les autres productions animales, la conchyliculture est frappée par diverses maladies dont certaines se comportent comme des facteurs limitants de la qualité ou de la quantité des productions. L' histoire de l'ostréiculture française a connu de tristes expériences en la matière, notamment dans les années 70 pour l' huître creuse portugaise, Crassostrea angulata ou encore pour l'huître plate, Ostrea edulis. En fait, nous ne disposons que de très peu de possibilités de protéger les mollusques bivalves vis à vis des maladies infectieuses. D' une part, les traitements,...

The phenomenon of summer mortalities of the Pacific cupped oyster Crassostrea gigas is observed in France since the beginning of the 90's. These mortalities are classically associated to younger stages and summer temperatures and occur during the reproduction period of the animal. The studies undertaken during the project Morest (2001-2005), showed that a number of biological and environmental risks, the interaction of them induces lethal stresses for animals in physiological weakness, exists in summer. Among these risks, that which is withstood by the oysters bred close to the sediment proved to be significant in intertidal areas. In Quiberon bay (southern Brittany, France), the breeding practices of sowing oysters in deep water is thus likely to expose...
