fish ladders  

Définition

  • Fish ladders are designed to allow fish passage around dams or other barriers by providing a series of relatively low steps that the fish may leap from one level to the next (hence the term ladder). Anadromous fish (e.g., salmon, sturgeon, and lamprey) need access to both the rivers where they spawn and the oceans where they spend their adult life.
