Zusammenfassung:White spot disease by Cryptocaryon irritans broke out among cultured Japanese flounder (Paralichehys olvivaceus) in october 1983, in Mie Prefecture. About 1000 2-years old fish died of this disease within three days. Multiple white spots with a pin point size were observed in the gills. The histopathological examination revealed that many parasites penetrated under the epithelia of gill filament and lamellae causing hyperplasia of epithelial cells and mucous cells at the parasitic areas.
