Abstract

Abstract

The larvae of bay scallop Argopecten irradians were treated with catecholamines and metal canons, to test the ability of these compounds to induce metamorphosis. Epinephrine (10^-4~10^-6 mol/dm³),norepinephrine(10^-5 mol/dm³)and L-DOPA(10^-5 mol/dm³)could increase metamorphosis significantly; at long duration exposure to excess KCl and CaCl₂,the metamorphosis of larvae was increased. When the larvae were induced with the optimum concentration of epinephrine, L-DOPA and KCl in a series time, they exhibited high sensitivity to epinephrine and L-DOPA, but the efficiency of K⁺ depended on time and dose. These suggest that epinephrine and L-DOPA appear to be via receptor-mediated pathway to trigger the process of metamorphosis; the elevated external concentration of K⁺ is to cause the depolarization of excitable cells and then enhance the larvae to metamorphose. The results of our study can offer an useful technique for inducing metamorphosis in spats commercial rearing of molluscs.
