Resumo: | The trophic relationship between a population of cultivated oysters and potential food was modeled in Marennes-Oleron Bay. Coupling the transport process of particulate matter with assimilation by a population of oysters was achieved through a box mode!. Transport between boxes was based on a mass conservation equation. Parameters were derived from volumes of the boxes, tidal movements and residual 110ws between boxes, and were computed from a numerical hydrodynamical model. Consumption, assimilation and respiration terms were put into an energetic budget equation which enabled simulation of growth. A result of the model was the variability of growth along an axis from North to South, which was related to the oysters' accumulated consumption of food. Finally, further development of the model was shown lo be necessary in order to be more realistic and predictive. Primary production and resuspension of sediment must be taken into account.
