Abstract

Decapod crustaceans and their associated fisheries are an important resource globally, and demand for seafood continues to grow alongside a growing human population. With a combined 2023 value of €36 million in Ireland, three species of brachyuran crabs, the velvet crab (Necora puberLinnaeus, 1767), edible crab (Cancer pagurusLinnaeus, 1758), spider crab (Maja squinado Herbst, 1788)), and the European lobster (Homarus gammarusLinnaeus, 1758) are decapods of commercial importance. These species are also important components of their respective ecosystems. Parasite infection can affect the health of crustaceans and may affect population productivity. Microparasites, including paramyxids (Hematodinium spp.) and microsporidians can infect decapod crustaceans and have a range of effects on their hosts. We assessed three microparasites in four crustacean species. Paramarteilia canceri was found in all three crab species, and we provide the first genetic confirmation in spider crabs. A microsporidian associated with cotton crab disease, Ameson sp., was identified in N. puber, along with a second species of microsporidian which will require further classification. None of the three parasite groups were identified in Homarus gammarus. Species of Hematodinium were not identified in any of the species studies. Our work highlights the need for parasite surveys to uncover parasite diversity and prevalence in crustaceans to help elucidate host-parasite interactions, and the potential impacts of parasites.

对爱尔兰的四种十足目甲壳动物(十足目:腕足动物、天体动物)进行微寄生虫筛选
十足类甲壳动物及其相关渔业是全球重要的资源,随着人口的不断增长,对海产品的需求也持续增长。在爱尔兰,2023 年的总价值为 3,600 万欧元,三种腕足类蟹,即绒蟹(Necora puberLinnaeus,1767 年)、食用蟹(Cancer pagurusLinnaeus,1758 年)、蜘蛛蟹(Maja squinado Herbst,1788 年),以及欧洲龙虾(Homarus gammarusLinnaeus,1758 年)是具有商业重要性的十足目动物。这些物种也是各自生态系统的重要组成部分。寄生虫感染会影响甲壳类动物的健康,并可能影响种群生产力。包括副寄生虫(Hematodinium spp.)和微孢子虫在内的微寄生虫可感染十足目甲壳类动物,并对宿主产生一系列影响。我们评估了四个甲壳类物种中的三种微寄生虫。在所有三种蟹类中都发现了癌副蠕虫,我们首次在蜘蛛蟹中进行了基因确认。在 N. puber 中发现了一种与棉蟹病有关的微孢子虫 Ameson sp.,还有一种需要进一步分类的微孢子虫。这三种寄生虫都没有在伽马鼬(Homarus gammarus)中发现。在任何物种研究中都没有发现半孢子虫的种类。我们的工作突出表明,有必要进行寄生虫调查,以发现甲壳类寄生虫的多样性和流行率,从而帮助阐明宿主与寄生虫之间的相互作用以及寄生虫的潜在影响。
