We conducted a bibliometric analysis in order to quantify and characterize the scientific knowledge about threatened freshwater fish species in Brazil based in studies published in peer-reviewed journals from Web of Science database from Clarivate Analytics. We verified an increase in the number of papers for threatened freshwater fish species in Brazil, especially in the last eleven years of studied period. The journals with the most papers were Neotropical Ichthyology, Environmental Biology of Fishes, and Journal of Fish Biology. The number of publications among the Brazilian regions and states is not homogeneous. The most studied threatened fish was piracanjuba Brycon orbignyanus . Some important gaps in scientific knowledge need to be addressed, such as the relatively small number and/or lack of studies conducted Brazilian states and with threatened freshwater fish species in Brazil.

巴西红色名录受威胁物种的科学知识：以淡水鱼为例

我们进行了文献计量分析，以根据 Clarivate Analytics 的 Web of Science 数据库中发表在同行评审期刊上的研究，量化和描述有关巴西受威胁淡水鱼类的科学知识。我们证实了有关巴西受威胁淡水鱼类的论文数量有所增加，尤其是在研究期间的最后 11 年。论文最多的期刊是 Neotropical Ichthyology、Environmental Biology of Fishes 和 Journal of Fish Biology。巴西地区和州之间的出版物数量并不相同。研究最多的受威胁鱼类是piracanjuba Brycon orbignyanus。需要解决科学知识中的一些重要差距，
