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&lt;sup&gt;-1&lt;/sup&gt; 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 (&lt;i&gt;Acartia&lt;/i&gt; spp. and cirriped nauplii) tended to feed more on small particles than the dominant species in the seaward part (&lt;i&gt;Temora longicornis&lt;/i&gt; and &lt;i&gt;Centropages hamatus&lt;/i&gt;), the potential grazing pressure on small phytoplankton (&lt;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.
