The metamorphic response of pediveliger larvae of Mytilus galloprovincialis to the neurotransmitter blockers chlorpromazine, amitriptyline, rauwolscine, idazoxan, atenolol and butoxamine, and to tetraethylammonium chloride (TEA) was investigated through a series of bioassays. Chlorpromazine, amitriptyline and idazoxin inhibited larval metamorphosis induced by 10-4 M epinephrine. The concentration that inhibited metamorphosis by 50% (IC50) for chlorpromazine and amitriptyline was 1.6 x 10-6 M and 6.6 x 10-5 M, respectively. Idazoxan was less effective with an IC50 of 4.4 x 1013 M. Moreover, these three inhibitors showed no toxicity at any of the concentrations tested. The larval metamorphic response to K+ was not inhibited by 10-3 M tetraethylammonium chloride after 96h. Thus, the neurotransmitter blockers chlorpromazine and amitriptyline are inhibitors of larval metamorphosis, and will be useful tools for antifouling studies.
