    摘要:

    神农架林区位于湖北省西北部,是长江中、上游水系的分水岭,其特殊的自然环境和众多的河源溪流孕育了独特的淡水鱼类区系,是我国生物多样性研究的热点区域之一,但是目前对于该区域鱼类多样性还缺乏必要的了解。基于2021—2022年调查结果,结合历史文献记录和相关类群最新分类学研究进展,更新了神农架林区鱼类物种名录。结果表明,神农架林区内共有淡水鱼类52种,其中土著鱼类44种,外来鱼类8种。物种组成以鲤形目鱼类为主,鲤科和鲴科物种数目最多。更新物种名录包含了6个神农架林区新纪录种、3个未被描述物种和12个发生分类变更的物种,并剔除了8个历史记录的种类,保留了此次调查未采集到的27个历史纪录种。此更新物种名录可为今后的神农架鱼类资源开发与利用以及其鱼类多样性的保护提供基础数据。

    Abstract:

    The Shennongjia Forestry District (Shennongjia) located in the northwestern region of Hubei Province, serves as the watershed between the upper and middle Chang-Jiang basin. Due to the unique natural environment and well-developed river networks, Shennongjia harbors a relatively high species diversity of freshwater fish, thus making it one of the hotspots areas of biodiversity research in China. However, there is still a lack of essential understanding of the fish diversity in this region. An updated checklist of fishes in the Shennongjia is provided, based on the results of the field survey conducted from 2021 to 2022 and combined with historical records of fish diversity in this district and the latest taxonomic progress of relevant taxa in the known literature.This updated checklist includes a total of 52 species, 44 of which are native and eight alien. The Cypriniformes dominates the fish fauna of Shennongjia. Two families of Cyprinidae and Xenocyprididae have the highest number of species. There are six newly recorded species, three previously undescribed species, and 12 species undergoing nomenclatural changes. Eight historically recorded species are excluded from this list, but 27 historically recorded species uncollected during this field survey are remained.The updated checklist presented here can serve as a fundamental reference for future biodiversity analyses and the biodiversity conservation of Shennongjia.
