Bilan des essais d’élevage de la palourde sur le littoral Morbihannais - 1983 ArchiMer
Perodou, Dominique; Dreano, Alain.
Ce document vient compléter les "bilan d'élevage de la palourde sur le littoral morbihannais" diffusés en 1979, 1981 et 1982 dans le cadre du contrat de Pays d'Auray. Il est constitué de 2 parties: - La première partie a pour but d'exposer et de commenter les résultats obtenus à partir des semis réalisés en mars et septembre 1980 et en avril 1981, ainsi que des essais de prégrossissement du printemps - été 1982. Une étude du milieu en relation avec les stations de prégrossissement du Pô (Carnao) et de La Trinité Sur Mer a été effectuée pendant l'été 1982, mais les résultats en sont restés inexploités, faute de temps (et de personnel) disponible. Ils feront, dans la mesure du possible, l'objet d'une publication ultérieure. - La deuxième partie du rapport,...

Les risques conchylicoles en Baie de Quiberon. Deuxième partie : le risque de prédation sur l’huître creuse Crassostrea gigas. Rapport final du projet Risco 2010-2013 ArchiMer

This study (“Risco”), implicating both industry, socio-economic experts and biologists, was funded by the Regional Council of Brittany, for 3 years (2010-2012), to investigate about the causes of oysters (Crassostrea gigas) mortalities in the bay of Quiberon (South Brittany, France). The protocol including both a sonar and video visualization of the bottom, and a monthly survey of 15 experimental oyster structures, allowed to assess the risk due to predation. A clear spatial distribution of the predatory effect was evidenced, with starfish (Asterias rubens and Marthasterias glacialis) predominating in the North-East sector, and boring snails (Ocenebra erinacea and Pterophora inornata) in the South-Center area.. The main mortalities from these predators...

Les risques conchylicoles en Baie de Quiberon. Première partie : le risque de mortalité virale du naissain d’huître creuse Crassostra gigas. Rapport final du projet Risco 2010-2013 ArchiMer

This study (“Risco”), implicating both industry, socio-economic experts and biologists, was funded by the Regional Council of Brittany, for 3 years (2010-2013), to investigate upon the origin of oysters (Crassostrea gigas) mortalities in the bay of Quiberon (South Brittany, France). Specific mortalities of adult oysters were recorded in this bay in 2006, whereas mortalities of one year old spat were observed since in 2008 in this bay as at a national scale. The experimental protocol in 2010, including a monthly survey of oyster batches at 15 experimental stations, allowed to assess the risk for one-year oysters, due to viral disease. A clear spatial distribution of this risk was evidenced, with a western area spared from contamination and mortality, and a...

Les risques conchylicoles en Baie de Quiberon. Troisième partie : le risque d’hypoxie pour l’huître creuse Crassostrea gigas. Rapport final du projet Risco 2010-2013 ArchiMer
Stanisiere, Jean-yves; Mazurie, Joseph; Bouget, Jean-francois; Langlade, Aime; Gabellec, Raoul; Retho, Michael; Quinsat, Kevin; Leclerc, Emilie; Cugier, Philippe; Dussauze, Morgan; Menesguen, Alain; Dumas, Franck; Gohin, Francis; Augustin, Jean-marie; Ehrhold, Axel; Sinquin, Jean-marc; Goubert, Evelyne; Dreano, Alain.
The project “Risco”, supported by the “Pôle Mer” and funded by the Regional Council of Brittany, deals with specific risks of mortality of oysters, Crassostrea gigas, cultivated on the bottom, in a subtidal bay of South Brittany : the bay of Quiberon (56, France). Massive mortalities of oysters were reported in summer 2006 in this bay, exclusively located in the deep muddy area with a positive gradient eastward. A validated biogeochemical model was applied in order to simulate the dissolved oxygen over 2000-2006 : it revealed several episodes of hypoxia, more or less intense according to years, but with the same spatial distribution. This approach proved 2006 to be the most hypoxic year since 2000. The hypoxia was due to a rare conjunction of 3 factors :...
