Abstract
A total of 23 individuals of glass eel (Anguilla japonica) were investigated from two estuarine barrages of the Nakdong River in 2016. It was observed that most individuals migrated through the eastern barrage, compared to the western. Individual numbers differed significantly along the corridor modification of the barrages; for example, the number of individuals was two to three times higher after the modification. These results indicate that modification of fish way and lock gate for has facilitated migration of glass eel, and our study potentially offers the operation strategy of estuarine barrage in order to induce more active migration of glass eel.
