This study provides a parasitological analysis of the elasmobranch species caught in the northern and central Adriatic Sea. Sixty-two marine leeches were recorded on 747 individuals of Raja clavata Linnaeus, 1758 (thornback ray), Myliobatis aquila Linnaeus, 1758 (common eagle ray), and Torpedo marmorata Risso, 1810 (marbled torpedo ray) caught in 56 hauls over a 5 yr period. All leeches were identified as Pontobdella muricata, which is a typical ectoparasite of benthic elasmobranchs. The prevalence of infection ranged from 7.11% on R. clavata to 12.00% on M. aquila. The intensity of infection, the preferential sites of attachment to the host, and the periodicity of infection were evaluated.
本研究对亚得里亚海北部和中部捕获的板鳃亚纲物种进行了寄生虫学分析。在5年期间的56次捕捞中，共捕获了747条1758年的孔鳐（Raja clavata Linnaeus，棘背鳐）、1758年的鹰魟（Myliobatis aquila Linnaeus，普通鹰魟）和1810年的斑电鳐（Torpedo marmorata Risso，大理石纹电鳐），并记录到62条海蛭。所有海蛭均被鉴定为多疣拟海蛭（Pontobdella muricata），它是底栖板鳃亚纲动物的典型体外寄生虫。感染率从孔鳐的7.11%到鹰魟的12.00%不等。对感染强度、在宿主体上的优先附着部位以及感染周期进行了评估。
