本文讨论了寄生鞭毛虫鱼身虫对养殖牙鲆幼鱼的高死亡率。日本比目鱼，Paralichthys olivaceus，是一种底栖比目鱼，常见于日本列岛和邻近地区的沿海沃茨。其幼鱼被大量生产，以提高野生渔业种群，并在日本用于商业网箱和池塘养殖。这种经济上重要的鱼类的大规模生产方法已经得到很好的建立。此外，许多寄生虫附着在鳃盖和口腔的内表面，也附着在眼睛的角膜上皮上。用100ppm福尔马林溶液浴处理1小时后，大部分鞭毛虫从鱼中除去，并且死亡停止。
This article discusses about high mortality of cultured juvenile Japanese flounder, Paratichthys olivaceus, caused by the parasitic flagellate Ichthyobodo. The Japanese flounder, Paralichthys olivaceus, is a benthic flatfish, common to the coastal waters around the Japanese Isles and adjacent regions. Its juveniles are mass-produced to enhance wild fishery populations, and for commercial net-cage and pond culture in Japan. Mass-production methods of this economically important fish have become well established. In addition, many parasites were attached to the inner surface of operculum and oral cavity, and also to the corneal epithelium of eyes. Most flagellates were removed from the fish and tnortalities stopped following a bath treatment with l00ppm formalin solution for lh.
