| Resumo: |
Grazing activity by the dominant zooplankton species in the Oosterschelde (SW Netherlands) was studied as part of an ecological survey accompanying the construction of a storm-surge barrier at the mouth of this tidal inlet. At station WEST, situated at the mouth, potential grazing pressure by the zooplankton amounted to 6% d<sup>-1</sup> of the phytoplankton standing stock and 18% of the primary production. At station EAST, in the inland part, 16% of the phytoplankton standing stock and 11% of the primary production was potentially consumed daily. Because the dominant zooplankton species in the inland part (<i>Acartia</i> spp. and cirriped nauplii) tended to feed more on small particles than the dominant species in the seaward part (<i>Temora longicornis</i> and <i>Centropages hamatus</i>), the potential grazing pressure on small phytoplankton (<20 µm Spherical Equivalent Diameter) was 3 times higher at station EAST than at station WEST. Ecological consequences of this difference are discussed in relation to developments to be expected in the post-barrier situation.
