文摘Conspecific foot mucus,excessive[K^+] and gamma-aminobutyric acid (GABA) showed different metamorphosis-inductive effect on the veliger of Haliotis discus hannai.The inductive effect of excessive [K^+]and GABA was developmental stage-dependent and dose-dependent,while that of conspecific foot mu-cus was only developmental stage-dependent.At 20℃ the veliger larvae became competent within 4 daysafter fertilization H.discus hannai larvae showed gregarious settlement pattern on the conspecific foot mu-ous under the conditions of either presence or absence of KCI or GABA.The present studies showed that the effect of conspecific foot mucus on abalone larvae metarnorphosis could be dose-independent.
