Deslous-paoli, Jean-marc - 1987Contrairement aux U.S.A., où ils ne représentent que 4,6% de la production marine totale (Chew & Donaldeson, 1985), les productions de mollusques principalement bivalves ne peuvent plus être considérées comme marginales. En France, 100 000 tonnes d'huîtres dont 98% de Crassostrea gigas (...Contributeur (s):

The accumulation of biodeposits brings about geochemical modifications of the underlying sediment, that are noticeable. The increase can reach 83% of the amount of organic carbon. By catching the deposits on the spot and by gathering them directly from the oyster tables we get a daily deposit that...Contributeur (s):

Shellfish farming leaves its mark on the environment in which it has developed, and the men who depend upon it. These changes have altogether balanced the lagoon cycle and have caused disastrous episodic events. Increased water c1arity caused by the uptake of particulate material by shellfish...Contributeur (s):

Heral, Maurice / Deslous-paoli, Jean-marc / Razet, Daniel / Prou, Jean - 1984The flesh production of oysters is mainly related to concentrations of dissolved carbon and free amino acids. The younger oysters are dependent on concentrations of pheopigments while the production of the older ones is related to chlorophyll a values of the water-sediment interface. Shell...Contributeur (s):

Deslous-paoli, Jean-marc / Heral, Maurice - 1986In the bay of Marennes-Oléron, the shell represents 60% and the dry flesh from 3 to 8.5% of the total weight of Crepidula fornicata. Seasonal changes in the biochemical composition of the dry flesh show two periods of spawning for the females and a single period of reproduction for the males, and...Contributeur (s):

Heral, Maurice / Deslous-paoli, Jean-marc - 1985The analysis of the official statistics of commercialised production of oysters (.Crassostrea angutata and Crassostrea gigas ) is achieved from 1866 to 1984 in term of their numbers and weights for the bay of Marennes-Oleron. The number of sanitary labels, multiplied by the mean weight of a crate...Contributeur (s):

Dans un bassin aquacole fermé (claires à huîtres), l'évolution qualitative et quantitative des matières en suspension subit des variations saisonnières directement liées aux capacité de production planctonique. Ainsi, à la fin du printemps et en été, le réchauffement des eaux s'accompagne...Contributeur (s):

A relation between the evolution of biochemical components of molluscs and the available amount of food is difficult to establish. In addition to energy relations we tried to use a factorial correspondance analysis in the study on relation between the evolution of biochemical reserves of tissues of...Contributeur (s):

Deslous-paoli, Jean-marc / Masse, Henri - 1982Hundred and ten samplings were made in the bay of Marennes Oleron, during the summer 1981. They allow to localize the hight loads of Crepidula fornicata in the middle of the bay (along the mud-bank of Charret and in the courante d'Oleron°. In this two Points, we value the dry biomass at about...Contributeur (s):

Heral, Maurice / Berthome, Jean-paul / Polanco Torres, E. / Alzieu, Claude / Deslous-paoli, Jean-marc / Razet, Daniel / Garnier, Jacqueline - 1981The appearance and changes of the oyster shell's gelatinous bags have been monitored since 1979. The increase in thickness that causes the growth into a "ball" can be explained by an overproduction of gel. The various environmental factors that can intervene in the secretion of gel...Contributeur (s):

Deslous-paoli, Jean-marc - 1982In 1979-1980, the main growth o oysters Crassostrea gigas, in the basin of Marennes-Oleron occured in June and July. The available amount of food and the energetic requirements for the reproduction are important factors determining growth. Tissue weight decreased after spawning until the end of the...Contributeur (s):

Berthome, Jean-paul / Deslous-paoli, Jean-marc / Heral, Maurice / Razet, Daniel / Garnier, Jacqueline - 1982The want of C. gigas spat-catching in the Marennes-oleron basin in 1981 can be due to various different reasons which are analysed here. Physico -chemical and trophic factors that can induce variations in the quality of gametogenesis, are successively in comparison with the year 1979 when...Contributeur (s):

Les conclusions de cette étude...Contributeur (s):
