| 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. |

| This presentation of the economic aspects of the Mediterranean shellfish culture is based on the first intermediary report and on different country reports (France, Spain, Italy) from EU's FAR program n°2-456 about "the analysis of the costs and prices for an economic study of shellfish culture management in Europe". The aim of the first part of this study is to identify the production and marketing techniques of the main EEC countries, analyse international trade between them and consider the development perspectives of these productions and trade.

| Bivalve predation by seabream has been observed worldwide and is a major concern for bivalve farmers. Farmed bivalve-seabream interactions must be better understood to ensure the sustainability of bivalve aquaculture. The objectives of this study were to characterize gilthead seabream Sparus aurata presence in a bivalve farm in Prevost Lagoon (Mediterranean Sea) using acoustic telemetry and to evaluate monthly losses of mussels Mytilus galloprovincialis and oysters Crassostrea gigas due to seabream predation over an 18 mo period inside the farm and at an unprotected experimental platform. Large (281 to 499 mm TL) seabream were more commonly detected in the bivalve farm than were small (200 to 280 mm TL) seabream. In contrast to small seabream, 90% of large... |

| Shellfish production, and production of marine bivalve molluscs in particular, is the main form of marine aquaculture in the European Union, with a production estimated at 1,200,000 tons in 1999 (Food and Agricultural Organization). Moreover, aquaculture production is rapidly expanding throughout Europe and is becoming a major economic resource in developing areas such as Northern Greece, Ireland, and northwestern Spain. These shellfish, mainly mussels, oysters, and clams, are produced in a natural environment. Due to variations in their environment, these otherwise edible species may however become unsafe for human consumption. Potential problems are amplified due to the nature of shellfish themselves: as they are filter feeders, they consume large... |

| This report includes a qualitative and descriptive approach of the oyster and mussel industries in the European Community. This report compares the structure of production, the marketsn the professional organisation, competition for the resource, legislation and support systemat the community levell. Technical and statistical datas are summarized to représent the structure of the industry, the trade flows and the main evolutions of the two industries in the EC. A summary of the county reports gives an overview of the present state of the industry in each country and suggest a first evaluation of constraints and prospects. [NOT CONTROLLDED OCR] |

| The oyster growth has been studied for a 10 year period, from 1986 to 1995, in four locations of the bay of Bourgneuf (French Atlantic Coast). The relations between oysters growth and the main molluscs stocks (cultivated oysters and wild mussels) or environmental factors (hydrobiology, currents, climatology) are analysed to understand the functioning of this shellfish ecosystem. As the water renewal time is about two months, primary production is essentially autochtonal. Phytoplankton development is controlled by the nutrients brought by the river Loire. An important part of the microalgac is composed by the microphytobenthos resuspended by west wind. High seston concentrations, measured on the North of the bay (150 mg/1 as an average), have a negative... |

| The process of ultrafiltration (UF) of natural seawater often encounters the problems of variation in water quality and coastal blooms. To validate the feasibility of UF in shellfish farms, this study compared the hydraulic performance and pollutant removal efficiency of the UF process with those of the commonly used treatments that combine several filtration steps with UV disinfection. The comparison was conducted in the cases of natural seawater and a coastal bloom. Given that the UF process encountered this specific pollution, this study evaluated the filtration performance of the UF process and the retention of total suspended solids (TSS), bacteria, phytoplankton, and zooplankton. A real coastal bloom was considered in the case study of an... |
