Article: Settlement behavior of black scallop larvae (Chlamys varia, L.) in response to GABA, epinephrine and IBMX.(gamma aminobutyric acid, 3-isobutyl-l-methylxanthine)(Report)

ABSTRACT Competent larvae of the black scallop Chlamys varia (L.) were treated with the neurotransmitter gamma-amino-n- butyric acid (GABA), the catecholamine epinephrine, and 3-isobutyl-l-methylxanthine (IBMX), at different concentrations and times of exposure, to test the effects of exposure to the compounds on larval settlement. After 24 h, maximum percentage of settlement (>30%) was induced by [10.sup.-5] M epinephrine. After 48 h, maximum settlement rate was also achieved by [10.sup.-5] M epinephrine (>54%). Exposure to [10.sup.-6] M epinephrine and to [10.sup.-6] M GABA also induced significantly higher larval settlement than in control larvae. By contrast, IBMX ...
