Abstract: To explore the research hotspots and development trends in the physiological responses of fish migratory behavior to river damming, this study analyzed relevant literatures from the past 20 years in the Web of Science Core Collection database using CiteSpace software for visual analysis. The analysis covered publication volume, country/regional collaboration, journal distribution, author networks, and keyword co-occurrence. The results indicate that the number of publications has shown a "fluctuating" upward trend, with United States and Canada the primary contributors. Research papers in this field are published in journals spanning multiple disciplines, including hydrology, ecology, biology, and environmental science, demonstrating clear interdisciplinary characteristics. Changes in oxidative stress indicators during fish migration are currently a key research focus. The complex physiological responses of fish migratory behavior in the altered flow environments of dammed rivers exhibit diversity in physiological indicators and tissue-organ specificity. Exploring the intricate mechanisms underlying the interaction between fish migratory behavior and internal physiological processes represents a future research trend.
