| 摘要 |
The invention relates to a fish migration aid comprising a plurality of interconnected individual pools (71) which form a flow path and each of which has an outer wall arrangement (72) forming a water holding space (77, 78) as well as a transfer slot (76) for allowing water to flow between adjacent individual pools (71). Each individual pool (71) includes an inner wall arrangement (73) which subdivides the water holding space (77, 78) of the individual pools (71) into first and second water holding spaces (77, 78). The water holding spaces (77, 78) are interconnected via a flow slot (75) to allow water to flow out of the first water holding space (77) into the second water holding space (78). |
