Bilan des connaissances sur la qualité de l'eau dans la zone du polder conchylicole de Bouin - Projet LEAUPOLD
Provedor de dados: 5
Autores: Hatt, Philippe-jacques; Stavrakakis, Christophe; Buchet, Vincent; Dupuy, Beatrice.
Le polder conchylicole de Bouin (Vendée) est le principal bassin français de production de naissains d’huîtres creuses issus d’écloseries. Depuis 2007, et malgré l’installation de dispositifs de traitement de l’eau, des anomalies dans les élevages voire des mortalités affectent la production des écloseries et nurseries du secteur, ainsi que celle de microalgues en grand volume d'une entreprise spécialisée. Les observations des professionnels orientent la recherche de la cause de ces mortalités sur les contaminants chimiques, notamment les pesticides utilisés par l'agriculture, dont les exploitations du polder agricole, qui jouxtent le polder conchylicole. Comme l'ont montré de nombreux travaux, certains de ces produits altèrent la qualité de l’eau de mer...

Estimation de la qualité biologique de l'eau sur le littoral atlantique du Sud-Ouest de la France à l'aide des tests de croissance des larves de Mytilus edulis
Provedor de dados: 5
Autores: His, Edouard; Quiniou, Francoise.
The quality of the seawater off the southwestern Atlantic coast of France was assessed by studying the effects of the water from three sites (Arcachon Bay, Mimizan and Capbreton) on larvae of the mussel (Mytilus edulis). Mussel larvae were raised in water samples taken at all three sites on March 12, 1991 and larval growth was monitored during 10 days. The results indicate that the water quality was best in the Bay of Arcachon, followed by Mimizan, whereas the water off Capbreton was possibly contaminated by pollutants.

Bilan des connaissance et des enjeux relatifs aux ressources marines de l'estuaire de l'Odet
Provedor de dados: 5
Autores: Billy, Stéphany; Peronnet, Isabelle.
The estuary of the Odet, which can be defined as a ria, is an integral part of SAGE, taken on by SIVALODET. This space was hardly studied and it seemed important to perform a full assessment of knowledge and issues relating to this ria's fragile and unstable ecosystem. This assessment must be performed according to several points of focus; it must first of all strive to retrace the history of the fisheries in the Odet, then make it possible to identify as clearly as possible the marine habitats that make up this site. With that, it must then bring to light the potential resources of the estuary and finally resituate the Odet in relation to the other Breton estuaries.
