説明
Upstream migration behavior of Japanese dace, Tyibolodon hakonensis, was investigated at a pool and weir fishway.<BR>Most of the upstream migrating Japanese dace were mature fish of 2 years old, and some immature fish. Upstream migration rate was examined for 7 days in succession, and was found to exceed 50% on day 2. In June and July, the upstream migration rate in 24 hours was found to increase as the discharge volume of the fishway increased.<BR>It was revealed that the water condition for the upstream migration of Japanese dace of 8.4 cm in body length is; water velocity below 100 cm/s, water depth over 15 cm, and water head below 28 cm.<BR>More swimming type was observed than the jumping type. The number of migratory fish reached maximum between 14 : 00 and 16 : 00.<BR>To design fishways suitable for Japanese dace, not only the hydraulic factors, such as discharge volume, but the way Japanese dace utilizes the fishway structures and water movement should be investigated and taken into consideration.
