Causes of Fish Lift Shutdowns on U.S. East Coast Hydroelectric Dams
Hydroelectric dams in the northeastern United States pose a challenge to the upstream spawning migrations of anadromous fishes, such as American Shad Alosa sapidissima , Alewife A. pseudoharengus , Blueback Herring A. aestivalis , Atlantic Salmon Salmo salar , and Sea Lamprey Petromyzon marinus .
