Centropages hamatus, Copepods, Feeding behavior of Copepods
Adult copepods Centropages hamatus were induced to feed on 10 to 40 µm Sephadex beads by adding Thalassiosira weissflogii or Scrippsiella trochoidea whole-cell extract, or filtrate from a T. weiss flogii culture , to a bead suspension. Beads were neither ingested in the absence of a chemical stimulus, nor in the presence of filtrates from cultures of S. trochoidea and Olisthodiscus luteus , or 0. luteus extracts. Extracts from both S. trochoidea and 0. luteus, and filtrate from an 0. luteus culture, appear to exert an inhibitory effect when applied in combination with T. weissflogii extract. Copepods acclimated to T. weissflogii for 24 h did not significantly increase their feeding rate on T. weissflogii flavored beads and did not ingest S. trochoidea-flavored beads.
