The relationship between communities of chub endoparasites (Leuciscus cephalus) fished in the Orta and Pescara Rivers in the Abruzzo region of Italy, and the quality of the water in which they are caught, were studied in surveys designed to evaluate the feed quality of fish in the inland waters of the Abruzzo. Samples were taken monthly from October 2000 to September 2001 in the Orta River (Buscesi District) and the Pescara River (near the Villareia bridge); a total of 86 chub were caught. During periods of low and moderate flow in both rivers, benthonic macroinvertebrates were sampled at the fish sampling sites to classify the water quality using the extended biotic index (EBI) method. The Orta River was moderately polluted and the Pescara River slightly more polluted than the Orta. A parasitological study of the fish was conducted using conventional methods. A morphological study of the parasites led to the identification of seven species of endoparasites. Five of these (Allocreadium isoporum, Caryophyllaeus brachycollis, Caryophyllaeides fennica, Rhabdocona denudata and Pomphorhyncus laevis) were found at both sampling sites, while Acanthocephalus clavula was found only in the Pescara River and Neoechinorhynchus rutili was found only in the Orta River.
在意大利阿布鲁佐地区，为评估该地区内陆水域鱼类的饲料质量而开展的调查中，研究了在奥尔塔河和佩斯卡拉河捕获的赤睛鱼（Leuciscus cephalus）体内寄生虫群落与捕鱼水域水质之间的关系。2000年10月至2001年9月期间，每月在奥尔塔河（布斯切西区）和佩斯卡拉河（靠近维拉雷亚桥）采集样本；共捕获86条赤睛鱼。在两条河流的低流量和中流量时期，在鱼类采样点采集底栖大型无脊椎动物样本，采用扩展生物指数（EBI）法对水质进行分类。奥尔塔河受到中度污染，佩斯卡拉河的污染程度略高于奥尔塔河。采用传统方法对鱼类进行寄生虫学研究。通过对寄生虫的形态学研究，鉴定出七种体内寄生虫。其中五种（等孢异肉吸虫、短颈鲤蠢绦虫、芬兰鲤蠢绦虫、裸腹杆咽线虫和光滑刺头线虫）在两个采样点均有发现，而棒状棘头虫仅在佩斯卡拉河发现，鲁氏新棘吻虫仅在奥尔塔河发现。
