This work reviews the significant community of digenean trematodes observed infecting the edible cockle, Cerastoderma edule, and the snail Nassarius reticulatus in the channel of S. Jacinto, Ria de Aveiro Estuary, Portugal. The Digenea observed comprise 15 species, belonging to the families Bucephallidae (1), Echinostomatidae (4), Gymnophallidae (3), Lepocreadiidae (1), Microphallidae (1), Monorchiidae (1), Renicolidae (1), Strigeidae, (1), and Zoogonidae (2). The species were studied by light microscopy and scanning electron microscopy. Information is included for hosts, sites of infection, prevalence, and a brief description of parasite surface morphology. The significance of these observations is compared with the presence of these digeneans from other regions, mainly the Atlantic Ocean and Mediterranean Sea. The Ria de Aveiro is a geographical location conducive to extensive species co-occurrence resulting from the overlap between southern (Mediterranean) and northern definitive hosts of the parasites. Differences in life cycle strategies were observed and discussed.
本研究回顾了在葡萄牙阿威罗河口圣雅辛托海峡中观察到的感染可食用鸟蛤（Cerastoderma edule）和织纹螺（Nassarius reticulatus）的复殖吸虫群落。观察到的复殖吸虫有15种，分属于以下科：头盘科（1种）、棘口科（4种）、裸茎科（3种）、鳞肉科（1种）、微茎科（1种）、单睾科（1种）、肾睾科（1种）、牛首科（1种）、后睾科（1种）和动殖科（2种）。通过光学显微镜和扫描电子显微镜对这些物种进行了研究。文中包含了关于宿主、感染部位、感染率以及寄生虫表面形态简要描述的信息。将这些观察结果的意义与来自其他地区（主要是大西洋和地中海）的这些复殖吸虫的存在情况进行了比较。阿威罗河口是一个地理位置，由于寄生虫南方（地中海）和北方终末宿主的重叠，有利于广泛的物种共生。观察并讨论了生命周期策略的差异。
