Values of nitrogen nutrients (ammonia, nitrite and nitrate) are compared with values of total organic nitrogen and urea. In summer, the consumation by micro and macrophytes is added to less important telluric input of nineral nitroge. However, an important provision of organic nitrogen remains. On the contrary, in winter, organic nitrogen does not represent more than 10% of total nitrogen. The autors postulate that populations of oysters are at the starting point of the organic nitrogen production cycle.

Crassostrea gigas Thunberg's infestation by Mytilicola orientalis. Mori in 1979 in the basin of" Marennes-Oléron presents two maxima,  one during spring, the other during autumn. The parasites have infested until 64 %of bred oysters.. The intensity of infestation la weak (93.5 %of oysters are infested by lass than six females) and depend on the hosts'size. By this fact, slgnificant impact appears only in spring and in winter. A middle infestation of more than three M. orientalis females seems to induce a significant decrease of rates of carbohydrates and of glycogen
