The present study was undertaken to determine the levels of endogenous catecholamines in various tissues of Patinopecten yessoensis, Crassostrea gigas and Mytilus edulis using high performance liquid chromatography (HPLC).Dopamine and noradrenaline were identified in the ganglia, gills and gonads. Dopamine levels in all tissue were from three to one hundred thirty times as much as noradrenaline levels. In the scallop, dopamine and noradrenaline levels decreased in the order of ganglia, gill and gonad. In the oyster, dopamine levels decreased in the order of gill and gonad, however both tissues showed the same amount of noradrenaline. Dopa and adrenaline were not detected in any of the tissues under the present experimental conditions.Dopamine levels of the scallops decreased during spawning induced by U.V. ray-irradiated seawater, whereas almost no change of noradrenaline levels were observed. These results suggest that the release of dopamine may be especially implicated in the spawning of scallops.
