In intensive shellfish cultures, biodeposit production leads to several kinds of problems: on one hand, with regard to the establishment of the carrying capacity of the site, and on the other hand, concerning the organic matter accumulation on the bottom and the consecutive risks of pollution (Haven and Morales-Alamo 1966, Bernard 1974, Kautsky and Evans 1987). Thus, an estimation of the biodeposition rate of mussels (Mytilus galloprovincialis) and oysters (Crassostrea gigas) was performed during a two year field study using an in situ sediment trap design, moored at mean depth (2 m). In parallel to these vertical flux measurements, seston concentrations and current speeds were recorded in order to quantify the upstream horizontal food fluxes.
