Aquatic Organism Passage 396

What is it

An engineered structure made to improve or provide passage for aquatic organisms. Removing barriers that restrict migratory fish and other aquatic organisms is part of creating effective passages.

How it helps

Migratory fish need to be able to reach their spawning grounds to reproduce. In many cases, fish travel long distances from their fresh water birthplaces to the ocean, and then make the long journey back to their original salt water breeding grounds to spawn. Man-made structures like culverts and roads can stop these fish from reaching their destination.

Building passages helps fish population numbers to stabilize or increase by connecting fragmented habitat.
