L'ostréiculture en baie de Bourgneuf. Relation entre la croissance des huîtres Crassostrea gigas et le milieu naturel : synthèse de 1986 a 1995 ArchiMer
Barille-boyer, Anne-laure; Haure, Joel; Baud, Jean-pierre.
The oyster growth has been studied for a 10 year period, from 1986 to 1995, in four locations of the bay of Bourgneuf (French Atlantic Coast). The relations between oysters growth and the main molluscs stocks (cultivated oysters and wild mussels) or environmental factors (hydrobiology, currents, climatology) are analysed to understand the functioning of this shellfish ecosystem. As the water renewal time is about two months, primary production is essentially autochtonal. Phytoplankton development is controlled by the nutrients brought by the river Loire. An important part of the microalgac is composed by the microphytobenthos resuspended by west wind. High seston concentrations, measured on the North of the bay (150 mg/1 as an average), have a negative...

Modélisation des cycles de l'azote et du phosphore dans les sédiments d'une lagune soumise à une exploitation conchylicole ArchiMer
Chapelle, Annie; Mesnage, Valérie; Mazouni, Nabila; Deslous-paoli, Jean-marc; Picot, Bernadette.
A simulation of nitrogen and phosphorus exchanges for the sediment-water interface is presented, The aim of the sttudy is to understand the dynamic behaviour of an eutrophie coastal lagoon (Thau, France), ln situ experiments were performed to estimate the different pools of nitrogen and phosphorus in the water column and in the sediment. The diffusive fluxes between them were also estimated. A numerical mode1, simulating nitrogen and phosphorus cycles, was developed and calibrated with data recorded .at two seasons (winter and summer). This study leads to the conclusion that is necessary to know the different pools of nitrogen and phosphorus in order to estimate which fraction is bioavailable and the rate of nutrient exchange between sediment and water. It...

Rapport d'activité 2001 du Laboratoire Conchylicole de Poitou-Charentes de La Tremblade ArchiMer
Le Moine, Olivier; Goulletquer, Philippe.
La compétence géographique assurée par le laboratoire dans ses fonctions concerne l'ensemble des Pertuis Charentais depuis le Sud-Vendée jusqu'à l'embouchure de la Gironde. Ce rapport d'activité tient compte de ces faits et présente par ailleurs les programmes de recherche selon la nomenclature établie dans le cadre du Plan Stratégique de l'Ifremer et dans la définition des mandats de laboratoires.
Tipo: Text Palavras-chave: Rapport activité; Réseaux surveillance; Ecosystème conchylicole; Production aquacole; Marennes Oléron.
