Fish Passage Facilities

Abstract A fish passage facility provides fish with a watered route around or through a barrier to migration in a fluvial system. Fish passage facilities have been designed for both natural and artificial barriers. Some passage facilities allow fish to propel themselves past the barrier, while others physically transport fish past the barrier. Fish passage facilities must provide passage during periods dictated by migratory requirements without injuring or unduly stressing fish. Fish passage facilities have been designed and constructed in North American, Europe, Russia, Latin American, Africa, Australia, New Zealand, China, and Japan. Depending on the region and type of application, fish passage facilities are also referred to as fishways, fish ladders, fish passes, fish bypasses, fish locks, and fish elevators.
