Affinage des huîtres creuses Crassostrea gigas en claires ostréicoles du Bassin de Marennes-Oléron : Etude des modifications de la Norme AFNOR-NF V 45 056 ArchiMer

Within its oyster quality project, the Marennes-Oleron Professional Organization (SRC) aims to improve the zootechnic rearing conditions in ponds for the Pacific cupped oyster C. gigas "fines de claires" and "speciales de claires", presently specified by the French norm AFNOR NF V45-056 (AFNOR, 1985). The proposed modifications concern a seasonal management of the oyster biomass per m2 , using 1 and 3kg/m2, during 2 weeks from April 1rst to October 31, and 3 weeks from November 1 to March 31, respectively. The Shellfish Aquaculture Laboratory of Poitou-Charentes (LCPC) carried out experiments to address the professional and decision-makers request for an assessment of those modifications on the final oyster quality compared to the current rearing...

Limiting nutrients of oyster pond seawater in the Marennes-Oleron region for Haslea ostrearia : applications to the mass production of the diatom in mesocosom experiments ArchiMer
Turpin, Vincent; Robert, Jean-michel; Goulletquer, Philippe.
Bioassays were carried out with the 'blue diatom' Haslea ostrearia Simonsen, which is responsible for oyster greening during the fattening period of Crassostrea gigas Thunberg in oyster ponds. Samples of seawater were taken from two oyster ponds: one without oysters and the other with 20 oysters per m_, maximal density allowed by the French AFNOR norm for 'refinement'. The aims were to clarify the nutrient requirements of this diatom, also to elucidate the eventual influence of C. gigas at this density on the seawater fertility and to envisage the mass production of this diatom by pond fertilization. Examination of cell numeric densities at the end of bioassays allows us to conclude that silicate was the first limiting nutrient, closely followed by...
