| The human-mediated introduction of marine non-indigenous species is a centuries- if not millennia-old phenomenon, but was only recently acknowledged as a potent driver of change in the sea. We provide a synopsis of key historical milestones for marine bioinvasions, including timelines of (a) discovery and understanding of the invasion process, focusing on transfer mechanisms and outcomes, (b) methodologies used for detection and monitoring, (c) approaches to ecological impacts research, and (d) management and policy responses. Early (until the mid-1900s) marine bioinvasions were given little attention, and in a number of cases actively and routinely facilitated. Beginning in the second half of the 20th century, several conspicuous non-indigenous species... |

| Species invasion is considered as a main factor impacting the marine biodiversity (CBD, 2008). A comprehensive review of species invasion along the French Atlantic coastline is carried out to assess the present status and side effects resulting from those invasions. Vectors of introduction concerning voluntarily and involuntarily, legal & illegal case studies are reviewed to provide baseline information relating invasion success and potential control. Historical case studies regarding shellfish aquaculture-fisheries development and impacts of exotic diseases (e.g., Bonamia ostreae) as well as hitchhikers (e.g., Rapana venosa) are discussed. Among at least 150 reported exotic species, around 10 species have highly significant side-effects on the... |

| The history of French oyster culture consists of a succession of developmental phases using different species, followed by collapses caused by diseases. The indigenous species Ostrea edulis was replaced first with Crassostrea angulata, then C. gigas. France is now the top producer and consumer of oysters in Europe, producing around 120,000 t of the cupped oyster C. gigas annually, and an additional 1500 t of the flat oyster O. edulis. Cupped oysters are produced all along the French coast from natural and hatchery spat. Various structures are used to collect spat from the wild. After a growing-on period, oysters are Cultivated by three main methods: (1) on-bottom culture in the intertidal zone or in deep water, (2) off-bottom culture in plastic mesh bags... |

| Monitoring hydrology is an essential part of studying an ecosystem such as the Marennes-Oléron Bay. Since 1977, bimonthly samples have been taken from five stations in the bay. These samples provide important information on physical characteristics (temperature, oxygen, salinity), nutrients (NH4, NO3, NO2, SiO3, PO4) and particulate matter composition (seston, chlorophyll a and pheophytin). |

| An hydrobiological monitoring survey has been carried out in the Bay of Marennes-Oléron since 1977. Five stations, distributed over the Bay, were sam pied twice a month. Spatial and temporal trends of the physical characteristics (i.e., seawater, temperature, salinity, dissolved oxygen and suspended matter), nutrients (azote, nitrite, nitrate, silicate) and organic variables (chlorophyll a and pheopigments) were assessed by using a statistical time-series analysis mode\. It was used to distinguish seasonal variability from long term trends. Pluviometric data as weil as the Charente River fluxes were similary analyzed by the model. The seasonal variability showed an homogeneous pattern over the five stations for all parameters, but the site-dependent... |

| The evaluation of the ecological and economical consequences of the hydrocarbon pollution of the Erika implies the setting up of monitorings, analysis and experiments in the short, medium and long term. Among the consequences to be evaluated, a great deal of attention has to be paid to the direct impact on the biology and production performances of the main shellfish species as about 30% of the national production (around 130,000 tons of oysters and 60,000 tons of mussels per year) is cultivated in the impacted area. The main difficulty in evaluating the effects of the contaminants on a distinct part of the ecosystem which is mostly dominated by a cultured population dwells in the different approaches to set up as well as the variability of the answers... |

| Après le naufrage de l'Erika, la question s'est rapidement posée de l'impact des hydrocarbures sur la santé des coquillages, car la pollution concernait des zones de production conchylicoles. Le suivi zoosanitaire en place dans ces zones permettait d'avoir des données de référence avant impact. Il a été choisi différents sites exposés de référence, qui ont fait l'objet d'analyse en toxicologie et en pathologie. A la différence du cas de l'Arnoco Cadiz, l'effort n'a pas été mis uniquement sur les huîtres mais aussi sur d'autres espèces de coquillages, comme les moules et des fouisseurs, particulièrement exposés comme les coques et les palourdes. La mesure de l'exposition effectuée par la Direction de l'Environnement Littoral (MONERlKA) montre qu'une... |

| Fisheries and aquaculture are of major importance to the coastal communities throughout the Bay of Biscaye. Almost half of French fishermen rely on catches from the Bay which achieve and estimated first sale value of more than 525m annually. Moreover, emblematic species such as eels have an additional economic as weil as social value for coastal communities. Similarly, the main French shellfish rearing areas are located within the Bay of Biscaye. They contribute predominantly to the yearly spat (mussel & oyster) recruitment, used to sustain the entire French shellfish industry. These activities have a direct impact on ecosystem functioning and biodiversity. Meanwhile, drastic environmental changes have been reported over the last 30 years, including a... |

| In European waters, significant economic damages to wooden structures are caused by bivalves molluscs and crustaceans. Treatments like copper-chrome-arsenic mixtures (CCA) were designed to prevent settlement of these wood borer species. However, limited and conflicting evidence regarding the toxicity to non-target organisms are available in the literature. This report aims to provide insights regarding the CCA leachates' toxicity to an important aquaculture species, the blue mussel Mytilus edulis for which much information on normal and stressed physiology is available for purposes of comparisons. The mussels are usually considered as a particularly suitable species for biological monitoring (Smaal and Widdows, 1994). To address the CCA leachate issue, two... |

| Integration of shellfish farming along the French shoreline (around 5500 km) has been progressive, as marine bivalve culture is a traditional activity in our country. The history of mussel culture relates that the "bouchot" technique (intertidal culture on wooden poles, producing annually around 60,000 tons) was developed as early as the XIIIth century, by a refugee attempting to capture birds by sticking branches of brushwood along the shore. The European flat oyster, Ostrea edulis, already appreciated at the Roman period, was first cultivated in France after Victor Coste introduced the technique of spat collection at the end of the XIXth century. The Pacific cupped oyster, genus Crassostrea, now the most-cultivated in France (around 120,000 tons marketed... |

| Historically, research involvement in shellfish industry appeared as soon as the 19th century with studies on oyster sanitary quality and nutritive values. Those aspects were developed to satisfy consumer's demand and public health issues. Later on, rearing technologies were developed to ensure optimization of the characteristics of shellfish population dynamic such as recruitment, growth, and mortality. In a third step, management of leasing grounds allocation required studies on ecosystems' functioning. It integrated over space and time relationships between environment (as a trophic resource) and shellfish production. Presently, new challenges regarding environmental protection and consumer's satisfaction have involved studies on optimized uses of... |

| At the present time, it has been determined that the average fish consumption per inhabitant should double by the year 2030, as it did between 1973 and 2003. Hence, what should we do to better preserve (if not increase) fish stocks that are constantly decreasing? How should aquaculture be considered? Can it meet this growing demand, and if so, what will be its environmental impact? How could developing countries ask aquaculture companies to take care of the extra costs linked to a sustainable aquaculture production? |
