In aquaculture, disease management and pathogen control are key for a successful fish farming industry. In past years, European catfish farming has been flourishing. However, devastating fish pathogens including limiting fish viruses are considered a big threat to further expanding of the industry. Even though mainly the ranavirus () and circovirus () infections are considered well- described in European catfish, more other agents including herpes-, rhabdo or papillomaviruses are also observed in the tissues of catfish with or without any symptoms. The etiological role of these viruses has been unclear until now. Hence, there is a requisite for more detailed information about the latter and the development of preventive and therapeutic approaches to complete them. In this review, we summarize recent knowledge about viruses that affect the European catfish and describe their origin, distribution, molecular characterisation, and phylogenetic classification. We also highlight the knowledge gaps, which need more in-depth investigations in the future.
在水产养殖中，疾病管理和病原体控制是成功养殖鱼类的关键。近年来，欧洲鲶鱼养殖业蓬勃发展。然而，包括限制鱼类病毒在内的破坏性鱼类病原体被认为是进一步扩大该行业的一大威胁。尽管主要的虹彩病毒（）和圆环病毒（）感染被认为在欧洲鲶鱼中得到了很好的描述，但在有或没有任何症状的鲶鱼组织中也观察到了更多其他病原体，包括疱疹病毒、杆状病毒或乳头瘤病毒。这些病毒的病因作用迄今尚不清楚。因此，需要更多关于这些病毒的详细信息，以及开发预防和治疗方法来彻底解决这些问题。在这篇综述中，我们总结了最近关于影响欧洲鲶鱼的病毒的知识，并描述了它们的起源、分布、分子特征和系统发育分类。我们还强调了知识空白，这些空白需要在未来进行更深入的研究。
