Fish ladder

Imagine a really tall staircase, but instead of people walking up and down it, fish are swimming up and down. These staircases are called fish ladders and they help fish get past obstacles like dams or waterfalls so they can reach their breeding grounds or feeding areas.

The fish ladder is made up of a series of small basins or steps that the fish can swim up. Each step is filled with water and has a small gate or barrier that prevents the fish from swimming back down. As the fish swim up the ladder, they jump or swim up each step until they reach the top.

The steps of the fish ladder are designed to be easier to swim over than a dam or waterfall, so even weaker or smaller fish can make the journey. Once the fish reach the top, they can continue swimming in their natural environment and complete their life cycle.

Fish ladders are important for preserving fish populations and maintaining healthy ecosystems. Without these ladders, fish may not be able to reach their breeding or feeding grounds, which could lead to declining populations, and even extinction.
