Mites as parasites infesting fish have been described in a few case reports involving Histiostoma anguillarum, H. papillata, and Schwiebea estradai. We describe the unexpected occurrence of oribatid mites of the genus Trhypochthoniellus on farmed tilapia Oreochromis niloticus. The fish had mites on the skin, fins, and gills, as well as in the mouth. The morphological characteristics of the mites, observed by optical and scanning electron microscopy, were consistent with those described for T. longisetus longisetus. All stages of development were observed, suggesting that the mites were able to actively reproduce on fish.
在一些涉及鳗鲡组织口虫、乳头组织口虫和埃氏施维螨的病例报告中，已描述了寄生于鱼类的螨类。我们描述了在养殖尼罗罗非鱼身上意外出现的毛甲螨属螨类。这些鱼的皮肤、鳍、鳃以及口腔中都有螨类。通过光学显微镜和扫描电子显微镜观察到的螨类形态特征与长鬃毛甲螨所描述的特征一致。观察到了螨类的所有发育阶段，这表明螨类能够在鱼身上积极繁殖。
