Glossary

Riverine migratory corridors are river systems that drain to the Sound. They are often bordered by flood plain trees and wetlands. Migratory species, such as Atlantic salmon, shad, and herring, use these rivers to travel to fresh waters miles away from Long Island Sound to spawn. Dams, culverts and other obstructions can block passage for fish to travel from the brackish waters of Long Island Sound to freshwater rivers to spawn. Removing these obstructions is preferable but not always practical. Recreational and commercial fisheries benefit when river corridors remain healthy and passable to migratory fish.
