Echantillonnage des populations naturelles de mollusques compétiteurs trophiques des huîtres cultivées Crassostrea gigas du bassin de Marennes-Oléron : aspects méthodologiques Stock assesments of the non-cultivated molluscs trophic competitors for oysters, in the Marennes-Oleron bay (Atlantic French coast) : methodological considerations

Sauriau Pierre-guy

The main problems involved in making biomass and density estimates of benthic mol1uscs are the choice of a sampling plan, the level of systematic errors and random errors. A stratified random sampling after optimum allocation was used in the case. The benthic molluscs estimates (biomass or density) ...

Francois Cyrille; Miossec Laurence; Garcia Celine; Arzul Isabelle; Joly Jean-pierre; Robert Maeva; Ferrand Sylvie

Created in 1992, the Repamo network (REseau de PAthologie des MOllusques – Mollusc Pathology Network) is in charge of the surveillance and monitoring of the marine molluscs health status along the French coast. It has a regulatory mission (European legislation 91/67 and 95/70) as well as a public se...

Water quality criteria and monitoring for marine mollusc culture : the French experience

Heral Maurice; Berthome Jean-paul

The impact of the main parameters of water quality which act on the life history of molluscs are presented. Two types of parameters are examined: the first are the physical-chemical parameters as temperature, salinity, turbidity, oxygen concentrations. They can be modified by perturbations directly ...

The variability of the operculum in Nucella lapillus (Gastropoda, Muricidae) from a colony in Audresselles, France

Keppens, M.; Dhondt, K.; Mienis, H.K.

In April 2007 the first two authors investigated the rocky outcrops on the beach of Audresselles, northwest France, for the presence of marine molluscs. Special attention was paid to Nucella lapillus (Linnaeus, 1758), also known as the Atlantic dog-whelk. A study of the collected material rev...

Temporal variability in the Pacific oyster spatfall along the French Coast: a new monitoring project Variation temporelle de l'abondance des naissains de l'huître creuse du Pacifique le long de la côte française : nouveau projet de surveillance

Pouvreau Stephane; Maurer Daniele; Auby Isabelle; Soletchnik Patrick; Mille Dominique; Bernard Ismael; Bedier Edouard

In France, spatfall of Pacific Oysters occurs traditionally in two shellfish area of the south west of France: the Marennes-Oléron bay and the Arcachon basin. The spat collected in both sites ensures approx. 70 % of the need of the French oysters production (the other part is produced in hatcheries)...

Recent innovations in cultivation of molluscs in french Polynesia

Aquacop Aquacop

Until recently, mollusc production in French Polynesia was only based upon fishing, for local consumption of edible bivalves mainly the oyster Saccostrea cucullata and for the exportation of pearl-oyster shells. As a consequence of parasitism problems on local oysters, a mollusc program was initiate...

L'ostréiculture en baie de Bourgneuf. Relation entre la croissance des huîtres Crassostrea gigas et le milieu naturel : synthèse de 1986 a 1995 Bay ostreiculture of Bourgneuf. Relation between the growth of the oysters Crassostrea gigas and the natural environment : synthesis of 1986 has 1995

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, cli...
