Wuyishan National Nature Reserve is located in the northwest of the Wuyi Mountain Range in northeastern Jiangxi Province. The fish fauna of mountain streams in the nature reserve was investigated seasonally from June 2015 to May 2016. A total of 2 505 samples were collected and classified into 7 families and 16 species. None of those collected in the nature reserve were alien species. Overall, 9 species (56.3% of the total number of fish species collected) were found to be endemic to China. The dominant species were Pseudogastromyzon fasciatus (IRI, 48.23%) and Onychostoma barbatulum (IRI, 46.39%); the common species were Acrossocheilus parallens (IRI, 9.76%), Formosania stigmata (IRI, 4.32%) and Zacco platypus (IRI, 1.15%). There were negative correlations between altitude and total number of species (S), altitude and Margalef index (D), and altitude and Shannon-Wiener index (H). Current threats to the conservation of fish species in the nature reserve were reviewed and management solutions were suggested.
