Designing Fish-Friendly Culverts (and bridges) is an environmental education science lesson about fish passage fish passage
Fish passage is the ability of fish or other aquatic species to move freely throughout their life to find food, reproduce, and complete their natural migration cycles. Millions of barriers to fish passage across the country are fragmenting habitat and leading to species declines. The U.S. Fish and Wildlife Service's National Fish Passage Program is working to reconnect watersheds to benefit both wildlife and people.

Introduction to Fish Migration

Fish need to move! They need to find food, find places to spawn, to hide or rest - and they need aquatic connections between all of these places. Were you aware that over 6-million man-made barriers, in the U.S. alone, keep fish from getting to where they need to go to grow and survive?

Discover why fish migrate, learn about barriers to their migration, and how to make a barrier more fish-friendly.

As you review the materials, consider adapting the lesson using migratory fish found in the waterways near you. You can learn more about the fish where you live by visiting your state's fish and game website.

Designing Fish-Friendly Culverts (and bridges) is a hands-on lesson about the amazing lives of migratory fish, and how barriers to their migration impact their survival.
