| 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... |

| 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... |

| 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,... |

| 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... |

| (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... |

| 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... |

| Un groupe de travail réunissant des biologistes et des économistes de l'IFREMER a réalisé en 1992 un document pour dessiner le cadre de l'évaluation technico-économique de la filière d'élevage de la coquille Saint-Jacques en France. Suite à ce premier document, un dossier plus complet a été constitué afin de faire le point sur l'ensemble des données techniques, biologiques et économiques disponibles en intégrant les aspects de la consommation des coquilles St-Jacques en France. |

| 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... |

| 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... |

| 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... |

| (subtidal on-bottom rearings), has been the year of the gestation for the RISCO-QB project (Risks in shellfish farming, in baie de Quiberon). Discussions with various potential partners have resulted in the project drafting with 3 main objectives : - estimation of the trophic capacity of the bay and adjustment of the rearing biomass, - impact of sediment nearness upon on-bottom technique and adjustment of the rearing practices, - appraisal of the impact of these 2 factors (trophic capacity and sediment nearness) on the budget of the farming companies and their consequences in the management of the mortality risk. Concurrently with the project writing, pre-studies, mainly methodological, have been conducted in the bay since 2007 in order to investigate the... |

| The Réserve Naturelle Marine (Natural Marine Reserve) of La Réunion island has been created recently (2007) for managing the coral reef of La Réunion West coast. In this area, traditional shore fisheries and spear-fishing are now regulated, controlled and under scientific survey in order to optimize the management of these fisheries, mainly leisure activities. This report draws up a first evaluation of the Reserve eco-guards monitoring in 2008-2009 over these fisheries, with double aim of : - improving the methodology : sampling strategy, terminology standardization ; data base setting up ; - collecting a data series for future evolution survey and comparisons with previous data (before creation of the Reserve). According to the collected data, the... |
