La gestion de l'eau douce en Seudre
Provedor de dados: 5
Autores: Masson, Daniel.
Suedre River, a small river in Charente-Maritime, is 45 km long and drains a 380 km2 river basin. Its flow rate is about 20 m3.s(-1). Beyond the Saujon agglomeration, the river extends to the sea via a 25-km long estuary which, through the action of tides, becomes a sea arm reaching 1 km in width. Freshwater and salt marshes line the banks of the Seudre River. Freshwater marshes are occupied by large cattle farms and intensive, irrigated crops. Salt marshes are used for oyster finishing—the final, fattening process in oyster farming. The coexistence of both types of activity is sometimes problematic, particularly in terms of water management, a frequent source of conflict. The climate in Charente-Maritime is characterised by dry summers and rainy winters,...

Gestion de l'eau douce et conchyliculture en Charente-Maritime
Provedor de dados: 5
Autores: Masson, Daniel.
The wetlands of Charente-Maritime represent 100,000 ha and are classified in three categories: flooded marshland valleys, freshwater marshes (farmed land) and coastal salt marshes (traditional and modern shellfish farms). The economic character of the latter two categories gives rise to conflicts of use. Both the agricultural and aquacultural professions are particularly sensitive to these conflicts due to the difficult economic times they are currently experiencing. The main issue is freshwater management, in both its qualitative and quantitative aspects. Charente-Maritime climate is characterised by rainy winters and dry summers and all players need water (or wish to evacuate it) during the same periods. It is thus necessary to mediate disputes or even...

Les contaminations microbiologiques des secteurs conchylicoles du Pertuis Breton - Dessalure et colimétrie
Provedor de dados: 5
Autores: Pautret, Soizic.
Le pertuis Breton est le site d'une production annuelle d'environ 10 000 tonnes de moules de bouchot, et d'environ 5 700 tonnes d'huîtres, essentiellement sur la côte nord de l'île de Ré. Cette activité est très dépendante de la qualité des eaux marines, qualité qui aurait tendance à se dégrader dans ce haut lieu de la mytilicultme française. En effet, lors de la plus récente étude de zones il a été constaté une diminution de la qualité sanitaire de l'eau. Certaines zones, dont l'estuaire du Lay et l'anse de l'Aiguillon, ont subi un déclassement. En l'état actuel des choses, si aucune mesure n'est prise pour enrayer cette dégradation du milieu côtier, ou si les exigences légales deviennent encore plus strictes, la profession se verra dans l'obligation de...
