Abstract：
The European conger, Conger conger, is a benthic marine fish species with a geographical distribution extending through the northeastern Atlantic and the Mediterranean. Despite being extensively distributed and widely appreciated by Spanish consumers, studies regarding parasite presence in this fish are scarce. In the present work, a hundred and eight specimens from the Mediterranean coast of northeastern Spain (Catalan waters) were surveyed for the presence of nematode parasites. Several species were morphologically identified: third-stage larvae of Anisakis type I (sensu Berland, 1961) (n = 131), third-stage larvae of Anisakis type II (sensu Berland, 1961) (n = 18), third- and fourth-stage larvae and adults of Hysterothylacium spp. (n = 48), adults of Cucullanus sp. (n = 391), and adults of Cristitectus congeri (n = 69). Moreover, some fish and decapode species were also observed as part of the host\'s diet, with the most detected preys being Micromesistius poutassou, Sardina pilchardus, Macropipus sp., and Goneplax rhomboides. This represents the first survey of nematode parasites infecting C. conger from the northeastern Spanish Mediterranean waters. Among the parasite species detected, the presence of Anisakis species should be highlighted as the ingestion of C. conger parasitized with these larvae could potentially lead to anisakiasis in consumers.
摘要：
欧洲的Conger,康格·康格,是一种底栖海洋鱼类，其地理分布遍及东北大西洋和地中海。尽管西班牙消费者广泛分发和广泛赞赏，关于这种鱼中寄生虫存在的研究很少。在目前的工作中,调查了西班牙东北部地中海沿岸（加泰罗尼亚水域）的108个标本中是否存在线虫寄生虫。在形态上鉴定了几种物种：I型Anisakis的第三阶段幼虫（sensuBerland，1961)(n=131)，II型Anisakis的第三阶段幼虫（sensuBerland，1961)(n=18)，三，四期幼虫和成虫。（n=48），Cucullanussp.的成虫。（n=391），和Cristectutuscongeri的成年人（n=69）。此外，一些鱼类和十足动物也被观察到作为宿主饮食的一部分，发现最多的猎物是Micromesistiuspoutassou，Sardinapilchardus,Macropipussp.,还有菱形菱形.这是对西班牙东北地中海水域感染C.conger的线虫寄生虫的首次调查。在检测到的寄生虫物种中，应强调Anisakis物种的存在，因为摄入被这些幼虫寄生的C.conger可能会导致消费者的anisakiasis。
