Fish ladder: History & Art

A fish ladder, also known as a fishway, fish pass, fish steps or fish cannon, is a waterway structure on or around artificial and natural barriers (such as dams, locks and waterfalls) that provides aquatic animals (particularly fish) a "detour" to facilitate natural movements and migrations of diadromous and potamodromous species.
