Harnessing eDNA technology to identify fish diversity and distribution in the Kashi River, a tributary of the Ili River, Xinjiang, China.

ABSTRACT: Monitoring species diversity and distribution patterns in remote ecosystems presents significant challenges due to vast geographic coverage, harsh environmental conditions, and the limited availability of traditional survey resources. Environmental DNA (eDNA) technology has been proven to be an effective method for biodiversity assessment, offering a non-invasive, cost-effective, and efficient solution. The study used eDNA metabarcoding technology to investigate fish communities in the Kashi River, a vital waterway in Xinjiang. Two-season of 37 eDNA water samples were taken from multiple sites, and 77 species were detected in April and 137 in September. Additionally, the results of spatial analysis showed that there were significant differences in fish composition among the different areas
