A comparative study of fish species composition in two spatially isolated nature reserves, Jiangxi, China

The ichthyofauna of mountain streams in the Danzhangshan Nature Reserve (DNR) and the Raoheyuan Nature Reserve (RNR) was investigated during 2008. A total of 385 samples were collected and classified into seven families and 14 species from the two nature reserves. There were 12 species belonging to seven families in the RNR, while eight species from four families were collected in the DNR. Overall, six species were found to be endemic to China, representing five families. The relative abundance of endemic species to China was higher in the RNR than in the DNR. Current threats to conservation of fishes in both nature reserves were reviewed and management solutions are suggested.
