Abstract

langsoni , Pseudohemiculter dispar , Ptychidio jordani , and Cranoglanis bouderius ), qualify for recognition as Threatened Species. Overfishing, water flow diversions and modifications, and the impacts of non-native species are the greatest threats to freshwater fish biodiversity in the Yujiang River. We recommend the adoption and enforcement of additional protected areas, improvement in approaches to sustainable fishery management, much better control of non-native species, and an improvement in and the expansion of fish life-history research. Our study contributes recommendations for the better protection of freshwater fish biodiversity and the development of sustainable fisheries in the Yujiang River.
