Many species of fish, including those that are important to the U.S. economy, migrate from the ocean to freshwater rivers and streams to spawn. If they make it past strong river currents and hungry predators, these determined fish may then find themselves blocked by man-made barriers, such as dams. Special “fish ladders” are built to help fish pass over these dams so they can continue swimming upstream to reach their spawning grounds.
