Abstract

The effects of the excretory-secretory products (ESPs) of several fouling organisms on the larvae of the sponge Halichondria panicea were assessed in laboratory experiments. The ESPs of the brown alga Laminaria saccharina significantly stimulated larval settlement and metamorphosis, while the metabolites excreted by conspecific adult colonies were harmful to H. panicea larvae. The ESPs of the ascidians Styela rustica and Molgula citrina and the blue mussel Mytilus edulis impeded both the settlement and metamorphosis of the sponge larvae to varying degrees. The chemical cues of the bivalve Hiatella arctica had no significant effect on the number of settled larvae of H. panicea but retarded their metamorphosis.
