Crustaceans are a valuable resource globally, both ecologically and economically, and investigations into their health are becoming increasingly important as exploitation rises. The microbiome plays a crucial role in crustacean immunity, and understanding its composition and structure can provide insights into the health of an organism and its interactions with various factors. In this study, we investigated the hepatopancreas microbiome of the velvet swimming crab, Necora puber, and compared its composition and structure with several study factors, including two different sampling points and infection with a paramyxid parasite, Paramarteilia canceri. To our knowledge, we provide the first description of a velvet crab microbiome, highlighting the dominance of a single microorganism, Candidatus hepatoplasma. We identified variations in microbiome composition between sampling points and discussed the possible processes affecting microbiome assembly. We also outline a core microbiome for the velvet crab hepatopancreas, consisting of 12 core phyla. Our study adds to the growing literature on crustacean microbiomes and provides a baseline for future investigations into the velvet crab microbiome and the health of this crustacean species.
甲壳类动物在全球范围内都是一种宝贵的资源，在生态和经济方面均如此，并且随着其开发利用的增加，对它们健康状况的调查变得越来越重要。微生物群落在甲壳类动物的免疫中起着至关重要的作用，了解其组成和结构可以深入了解生物体的健康状况及其与各种因素的相互作用。在本研究中，我们调查了绒毛近方蟹（Necora puber）的肝胰腺微生物群，并将其组成和结构与几个研究因素进行了比较，包括两个不同的采样点以及感染副黏孢子虫寄生虫（Paramarteilia canceri）。据我们所知，我们首次描述了绒毛蟹的微生物群，突出了单一微生物“候选肝浆菌”（Candidatus hepatoplasma）的优势地位。我们确定了采样点之间微生物群组成的差异，并讨论了影响微生物群组装的可能过程。我们还概述了绒毛蟹肝胰腺的核心微生物群，由12个核心门组成。我们的研究为关于甲壳类动物微生物群的不断增加的文献增添了内容，并为未来对绒毛蟹微生物群和该甲壳类物种健康状况的调查提供了基线。
