Resumo: | A large proliferation of Noctiluca scintillans (Dinophyceae: Noctilucidea) was observed in neritic waters off the central Cantabrian coast during late April 1995. Eggs of Acartia clausi (Crustacea: Copepoda) were the most conspicuous prey within vacuoles of Noctiluca. Noctiluca ingested 73 % of the total stock of A. clausi eggs. This intense predation on copepod eggs could potentially affect the recruitment of nauplii. The potential impact on the stock of Acartia clausi eggs and on the daily egg production of the population is discussed. There is a negative correlation between the average number of ingested eggs by a single Noctiluca cell and the abundance of Noctiluca. This fact, coupled with the lack of significant correlation between the former variable and the abundance of Acartia clausi eggs, suggests that interference processes play a major role in regulating the predator-prey interaction between Noctiluca and Acartia eggs.
