 note = {Currently, a need exists to preserve environments in which living creatures can create habitats rather than simply preventing the riverbed evolution and landslides usually associated with disasters. The installation of fishways in erosion control/conservation dams has been used for this purpose. Inadequacies such as low flow-rates in existing fishways or fish having difficulty gathering at the fishway entrance have been documented (Irasawa et al. 1992). Various studies have been conducted on such controversial points, and improvements have been made. However, compared with functional research, much less research has examined maintenance management with regard to important controversial topics related to fishways. Consequently, the present study clarified the actual conditions of fishways in mountain streams through questionnaire surveys.},
