Zusammenfassung:PROBLEM TO BE SOLVED: To provide a corner fish passage capable of forming a region of a gentle stream and suitable as a pathway for fish without forming an independent stream for a fish passage. SOLUTION: The fish passage is formed at the bottom wall of a water passage. A plurality of generally V-shaped baffle boards each comprising a vertical plate 47a and lateral plates 47b joined to the vertical plate so as to extend from both sides of the vertical plate diagonally upward are arranged along the bottom wall of the water passage at predetermined intervals. The region of a gentle stream which can form the pathway for fish is formed at portions along the generally V-shaped inner and outer parts of the baffle boards. COPYRIGHT: (C)2010,JPO&INPIT
