Dynamique et enzymologie de la digestion chez l'huitre Crassostrea gigas
Provedor de dados: 5
Autores: Boucaud, C; Lebesnerais, C; Lubet, P; Lihrmann, I.
Feeding experiments carried out on Crassostrea gigas allowed the authors to set up the stages and the timing of the movement of food throughout the digestive tract. Various activities involved in digestion (glycosidases, esterases, and peptidases) were investigated histochemically in the digestive tract in order to localize the sites of absorption and the sites of protein and carbohydrate digestion. An explicative model of the different stages of digestion is proposed.

Introduction: Marine farming in France is currently very widely dominated by oyster farming. French oyster production totals 148,467 tons, for a turnover of close to 280 million euros, making France the leading European producer. The two main species concerned are the cup oyster, Crassostrea gigas (140,000 tons) and the flat oyster, Ostrea edulis (2,000 tons), the production of which has collapsed since 1970 following successive epizootics of Marteilia refringens and Bonamia ostreae. French oyster farming is thus in a situation of quasi single-crop farming, with more than 90% of tonnage pertaining to the cup oyster (FAO data from 1993).  This situation of quasi single-crop farming leads to the pessimistic observation that one hypothetical crisis in the...

Croissance, engraissement et mortalité de l'huître creuse Crassostrea gigas en baie de Bourgneuf  : comparaison de quatre secteurs ostréicoles
Provedor de dados: 5
Autores: Haure, Joel; Baud, Jean-pierre.
A study on mortalities, growth and fattening of the oyster Crassostrea gigas was carried out spring with the autumn 1987 in four sites of bay of Bourgneuf. Mortalities, more important in spring, prove to be higher in the sectors North compared to the Southern sectors of bay of Bourgneuf.  The performances of growth are rather weak when they are compared with other French oyster sectors. They however present a better production in the cattle-breeding areas located at the South of bay. The spring phase is marked by the formation of glucidic reserves, at the moment of the reheating of water, which is quickly transformed, in the majority of the sites, in lipids of reserves of the ovocytes, during the gamétogenèse.   The state of fattening of Crassostrea gigas...
