fish ladders

A fish ladder is a structure built around barriers like dams to help fish migrate upstream or downstream. It provides a series of stepped pools or channels that mimic natural river conditions, allowing fish to gradually ascend or descend around obstacles. This ensures they can reach spawning grounds or continue their natural life cycle. Fish ladders are vital for maintaining healthy fish populations and supporting ecological balance, especially in rivers impacted by human-made structures. They are carefully designed to accommodate different species and their swimming abilities, facilitating safe and efficient fish movement across barriers.
