✦ Synopsis
Population dynamics of the dominant calanoid copepods
Acartia spp. and Tempora longicornis were followed during a dense spring bloom of Phaeocystis pouchetii in the northern Wadden Sea off Sylt. Positive correlations between algal concentration and abundance of the copepod species suggest that P. pouchetii constitutes an important food organism for the copepods in spring and early summer. In laboratory experiments, feeding and ingestion rates ofA. clausi and T. longicornis were determined when P. pouchetii colonies were offered as food. Maximum food intake reached 48% of body carbon per day in A. clausi and 87% in T. longicornis, respectively.
