Abstract: This study conducted to investigate the status of early-stage fish resources in Jinping bend in the lower reaches of the Yalong River in 2019 and 2020. The results showed that there were 19 fish species in 4 families and 2 orders. Among these, 7 species spawned drifting eggs, 5 out of which were endemic to the upper reaches of the Yangtze River. These were Leptobotia elongata, Jinshaia sinensis, Jinshaia abbreviata, Sinibotia reevesae, and Coreius guichenoti. The number of fish eggs flowed through the Lizhuang section was estimated to be 103.07×10⁴ and 388.58×10⁴ in 2019 and 2020, respectively, and the dominant species were Jinshaia sinensis and Lepturichthys fimbriata. According to the analysis, there were many spawning sites of fish drifting upstream of the Lizhuang section, and the larger spawning grounds were mainly located in the Yandai, Nanhe-Qingna, and Lizhuang sections from upstream to downstream. Species composition of drifting fish eggs was similar to historical studies, but the spawning scale was on the decline, especially those river migratory fishes such as Leptobotia elongata, Coreius guichenoti and Rhinogobio ventralis, which spawned sporadically only in the present survey. Although affected by many factors such as hydropower cascade exploitation, overfishing, sand mining and gold digging, as the longest flowing section in the lower reaches of the Yalong River, the Jinping bend is still a crucial distribution area for breeding of many fishes, and the spawning scale has gradually increased in recent years. On the basis of existing protection measures, we suggested expanding the scope of the existing reserve to protect the fish spawning habitats, restoring river connectivity to meet the demand of migration, and optimizing ecological operation, to effectively protect fish resources in Jinping bend of the lower Yalong River.
