Abstract

Currently, water pollution has become severe, affecting biodiversity in the Thuong River basin. Therefore, investigating aquatic species in this area contributes to the development of a database and the conservation of biodiversity. However, data on fish species in this region remain incomplete. This study aims to record the fish species composition for the first time in the Thuong River basin in Bac Ninh Province. Through three surveys conducted in April, August, and December 2024 at five locations, a total of 52 fish species were recorded, belonging to 42 genera, 22 families, and 9 orders. Among them, the Cypriniformes was the most diverse (27 species). Ten fish species of marine origin were also recorded in this area. Two species (Pseudohemiculter dispar, Oreochromis mossambicus) are classified as vulnerable on the International Union for Conservation of Nature Red List, and Pseudohemiculter dispar is also listed in the Vietnam Red List with the same threat level; two species (Clupanodon thrissa, Megalobrama terminalis) are listed under Group II according to Decree No. 26/2019/ND-CP. River habitats were more diverse than pond, lake, and rice field. August recorded the highest number of species (35 species). These results provide scientific evidence for management, conservation, and sustainable exploitation of fishery resources in the local area.
