Secondary Production of the Brackish Copepod Communities and Their Contribution to the Carbon Fluxes in the Westerschelde Estuary (the Netherlands)

The zooplankton community of the brackish part of the Westerschelde estuary (November 1989–October 1990) was dominated by two calanoid copepods, Eurytemora affinis and Acartia tonsa. Eurytemora was present during a longer period of the year and was much more important in terms of total abundances and biomasses than Acartia.
