| The oyster culture basin of Marennes - Oléron is characterized by the tastiness of its oysters and the good quality of its waters, and thus of its shellfish. On that account, the quasi-totality of the production areas are ranked A for non-burrowing shellfishes, thus confirming the privileged character of the basin. This microbiological and chemical quality contributing to the reputation of the basin's shellfish farms needs to be preserved. In this purpose, the Regional Shellfish Culture Section of Marennes - Oléron (SRC) approached the Ifremer in order to continue the monitoring of the microbiological quality carried out on different production areas susceptible to be affected by some bacteriological contaminations leading to a deterioration of the... |

| Breeding Crassostrea gigas was conducted in three rivers of Morbihan (Brittany France). During one year, every four months, their increasement was examined. In one of these rivers, oysters showed, however their age and their origin, an abnormal increasement. Shells were very thick, with many chambers. At the opposite, in the two others rivers, oysters did not show that disordered state. Shells were sound and their linear increasement was harmonious |

| De 1970 à 1972, les élevages de Crassostrea angulata Lamarck furent décimés. Ce phénomène apparut d'abord en Bretagne, provocant vers la fin de l'année 1970, leur disparition à Etel et Penerf. Puis en 1971, les centres de Paimpol, de Cancale, du Croisic et de Mesquer furent touchés. Une légère mortalité réapparut en Bretagne au début de 1972. Les premières huîtres frappées furent les C. angulata importées du Portugal. Elles présentaient pourtant jusque là une croissance satisfaisante. Celles originaires de France semblèrent mourir moins massivement. Pour reconstituer leurs élevages, les ostréiculteurs avaient importé des Crassostrea gigas Thunberg, communément appelées huîtres japonnaises Introduites massivement à partir de 1969, cette huître n'a jamais... |

| La loi sur la protection et la mise en valeur des paysages élaborée par le ministère de l'environnement a pour but de faire prendre en compte la protection des paysages dans les plans d'aménagement. dans les plans d'occupation des sols et dans tous les documents correspondant à des actions pouvant en modifier l'aspect visuel. Cette loi met l'accent sur deux aspects fondamentaux: - la protection des paysages: * sans interdire l'implantation de nouvelles activités ni la construction d'habitations * sans exclure des modifications importantes de l'organisation des activités agricoles (par exemple: remembrement) à condition que l'aspect visuel soit préservé. - la prise en compte, dans différents textes, du maintien des paysages. * Les documents tels que les... |

| The microbiological classification of the Marennes-Oléron shellfish farming area (according to Council Directive 91/492/EEC) let appear sorne periodically polluted spots. A research of the potentiel sources has been conducted around these spots. Twelve points were sampled during a year with faecal coliforms and streptococcus contamination level in water (and shellfich when possible). Several microbiological pollution sources were found, in the Seudre estuary (umstream) and in Oléron island : lack of, or ineffective sewage systems, cattle farming without convenient manure treatrrtent, and so on .. Recommendations are given to improve this situation. |
