The present paper comprises a systematic survey of helminths from 202 red groupers, Epinephelus morio (Valenciennes) (Pisces: Serranidae), the most important commercial marine fish in the region, collected from ten localities off the Yucatan Peninsula in the Gulf of Mexico during 1994-1996; two more helminth species were recorded from E. morio earlier. Thirty species of helminths were found: Monogenea 1, Cestoda 3, Trematoda 17, Nematoda 8, Acanthocephala 1. Of them, 15 species were adults, whereas 15 species were larval stages parasitizing piscivorous elasmobranch and teleostean fishes, birds and marine mammals as adults. A new didymozoid trematode, Allonematobothrium yucatanense sp. n., is described from the fins of this host. Most findings represent new host- and geographical records. Philometra margolisi, a nematode parasitizing the gonads, is undoubtedly the most important parasite affecting the reproduction of the host, endangering E. morio in aquaculture. Larval anisakid nematodes (Anisakis, Pseudoterranova, Hysterothylacium) recorded from the red grouper in the region of the southern Gulf of Mexico are important from the viewpoint of public health.
本文对1994年至1996年期间从墨西哥湾尤卡坦半岛附近十个地点采集的202条红石斑鱼（Epinephelus morio Valenciennes）（鱼类：鮨科）中的蠕虫进行了系统调查，红石斑鱼是该地区最重要的商业海洋鱼类；此前已从红石斑鱼中记录到另外两种蠕虫。共发现30种蠕虫：单殖吸虫1种、绦虫3种、吸虫17种、线虫8种、棘头虫1种。其中，15种为成虫，15种为幼虫阶段，成虫寄生于食鱼的板鳃亚纲和硬骨鱼类、鸟类及海洋哺乳动物体内。本文从该宿主的鳍中描述了一种新的双身虫科吸虫，即尤卡坦异双身吸虫（Allonematobothrium yucatanense sp. n.）。大多数发现代表了新的宿主和地理记录。寄生于性腺的线虫马氏费洛线虫（Philometra margolisi）无疑是影响宿主繁殖的最重要寄生虫，对水产养殖中的红石斑鱼构成威胁。从墨西哥湾南部地区的红石斑鱼中记录到的幼虫型异尖线虫（异尖线虫属、伪新蛔线虫属、宫脂线虫属）从公共卫生角度来看很重要。
