In this study, the habitat suitability index (HSI) was calculated through on-site monitoring twice on July 9-10, 2021 and November 6, 2021. During the site monitoring 1,625 objects comprising 35 species belonging to nine families were collected from six survey stations. In addition, physical data, such as depth and velocity, and biological data, such as fish species and populations, were collected. The dominant and subdominant species were Pungtungia herzi (28.00%) and Zacco koreanus (19.26%), respectively, followed by Zacco platypus (13.72%), Rhodeus pseudosericeus (7.63%), Pseudogobio esocinus (3.75%), Coreoleuciscus splendidus (2.52%), Acheilognathus rhombeus (2.03%), and Acheilognathus lanceolatus (2.03%). To calculate the HSI using the Instream Flow and Aquatic Systems Group method, physical information, such as depth and velocity, were used from three selected fish species. P. herzi was selected as the dominant species, and Z. platypus and Z. koreanus as the subdominant species. For P. herzi, the water depth was 0.5 -0.6 m and the velocity was 0.0–0.1 m/s. For Z. platypus and Z. koreanus, the water depths were 0.3-0.5 m and 0.4–0.5 m, respectively, while the velocity was 0.0–0.1 m/s for both species. These species have an HSI value of 1.0 in this range. The HSI developed in this study may be utilized to calculate environmental ecological flow and improve river health. Additionally, it is judged to be highly useful as basic data for river restoration plans.
