Abstract

Between 2015 and 2020, 2 092 specimens of cartilaginous fishes (Chondrichthyes: Elasmobranchii) belonging to eight species and five genera were sampled along the Tunisian coast and examined for their cymothoid parasites, Among the eight examined elasmobranch species, only three were infested, Five parasite species were identified: Anilocra physodes, Emetha audouini, Ceratothoa oestroides, C. parallela and Nerocila orbignyi, These parasites presented three maturation stages: ovigerous females of A.physodes and E. audouini, adult non-ovigerous females of N. orbignyi, and juvenile females of C. oestroides and C. parallela, Most of these parasitic isopods were found on a single host species except for the two Ceratothoa species. We report new host-parasite associations, including the presence of A. physodes and E.audouini on smooth-hound Mustelus mustelus, the occurrence of C. oestroides and N. orbignyi on cartilaginous fish species, and the presence of C. parallela on black smooth-hound Mustelus punctulatus and M. mustelus. Parasitological indices and the seasonal variation in prevalence of the collected cymothoids, as well as parasitic species richness, are presented.
突尼斯水域棘鱼科鱼类感染的新宿主-寄生虫群(甲壳纲,等足纲)
2015年至2020年间,在突尼斯海岸采集了属于五属八种的2092个软骨鱼类标本(软骨鱼类:Elasmobranchii),并对其类囊状寄生虫进行了检查。在八个检查的软骨鱼类物种中,只有三个受到了感染。确定了五个寄生虫物种:Anilocra physodes、Emetha audouini、Ceratothoa estroides,这些寄生虫呈现三个成熟阶段:A.physodes和E.audouini的产卵雌性,N.orbignyi的成年非产卵雌性,以及C.estroides和C.parallea的幼年雌性。除两个Ceratothoa物种外,这些寄生等足类大多在单个宿主物种上发现。我们报道了新的宿主-寄生虫关联,包括在光滑猎犬Mustelus Mustelus身上存在A.physodes和E.audouini,在软骨鱼类物种上出现C.estroides和N.orbignyi,以及在黑色光滑猎犬Mustellus punctulatus和M.Mustelus上存在C.parallea。介绍了寄生虫学指标和收集的类Cymothoid流行率的季节变化,以及寄生虫物种的丰富度。

期刊介绍: The African (formerly South African) Journal of Marine Science provides an international forum for the publication of original scientific contributions or critical reviews, involving oceanic, shelf or estuarine waters, inclusive of oceanography, studies of organisms and their habitats, and aquaculture. Papers on the conservation and management of living resources, relevant social science and governance, or new techniques, are all welcomed, as are those that integrate different disciplines. Priority will be given to rigorous, question-driven research, rather than descriptive research. Contributions from African waters, including the Southern Ocean, are particularly encouraged, although not to the exclusion of those from elsewhere that have relevance to the African context. Submissions may take the form of a paper or a short communication. The journal aims to achieve a balanced representation of subject areas but also publishes proceedings of symposia in dedicated issues, as well as guest-edited suites on thematic topics in regular issues.
