致病原因和疾病鱼体病是由一种有鞭毛的鱼体属原生动物引起的，正式名称为Costia。这些寄生虫非常小(5-10微米)，有自由游泳和附着的阶段，很容易在检查中被忽视。死鱼是一种专性寄生虫，寄生在包括鲑鱼在内的鱼类的皮肤和/或鳃上。当鱼腥鱼出现在鳃上时，会严重降低幼年鲑鱼适应海水的能力。
I. Causative Agent and Disease Ichthyobodiasis is caused by a flagellated protozoan of the genus Ichthyobodo, formally known as Costia. These parasites are very small (5-10 um) with both free swimming and attached stages that can easily be overlooked in an examination. I. necator is an obligate parasite infesting the skin and/or gills of fishes including salmonids. When present on gills, Ichthyobodo seriously reduces the ability of young salmon to adapt to seawater.
