Abstract:

The Luoxiao Mountains is a key area of biodiversity conservation in China, and is also watershed of the Ganjiang River and Xiuhe River basins and Xiangjiang River basin. However, there is little research on fish diversity in the Luoxiao Mountains, and species composition, distribution and threat factors are unclear. Here, fish specimens were collected in eleven streams of the Luoxiao Mountains between 2014 and 2018. The fish specimens collected from the Luoxiao Mountains belonged to 113 species, 64 genera, 17 families and 5 orders. A total of 108 fish species were found in the eastern slope of the Louxiao Mountains, which were more than those from the western slope (72 species). The ecological types of fish was mainly settlement, demersal and carnivorous, and fauna was mainly the endemic fishes of the river plain in East Asia. From the perspective of species diversity, the Suichuan River, Yuanshui River, Shushui River and Xiuhe River had a high diversity in fish species, and a low diversity occurred in the Jinjiang River and Fushui River. The analysis of beta diversity showed that some differentiation in fish species was found between the Suichuan River and Jinjiang River, Heshui River, Fushui River.
