| Outline of Final Research Achievements |
To contribute to the design technology of fishways for small migratory fish, such as ice goby (Leucopsarion petersi), pond smelt (Hypomesus nipponensis), and goby (Gymnogobius urotaenia sp.), the authors conducted a field swimming experiment to determine the swimming ability of these fish. Results show that the relation between the swimming speed and the swimming distance corresponding to the velocity condition of the required hydraulic factor for fishway design was clarified for the first time nationally. The analysis results of the swimming ability of these fish are available as a guideline for the hydraulic design of mild slope-type and a pool-type fishways with partitions.
