Abstract

The ladder exit at its lower point has an adjustable surface area so that the flow of water through the exit can be maintained at a level which is not too high for preventing a fish from swimming upstream through the ladder. The ladder comprises a vessel with an exit at its lower point and a pipe linking the vessel to a connecting part at the upper point.
