The fallfish (Semotilus corporalis) is a North American freshwater fish, a chub in the family Cyprinidae.
Spawning males build stone nests, known as a redd, which form a prominent part of the bottom on many streams throughout the northeast.
[4] Fallfish are found in the northeastern United States and eastern Canada, where they inhabit clear streams, lakes, and ponds.
[6] Fallfish are often encountered when fishing for more desirable species, but their large size, dogged fighting style, powerful runs on light tackle, and willingness to strike make them a worthy quarry in their own right.
The International Game Fish Association (IGFA) All Tackle World Record for fallfish is 3 pounds 9 ounces (1.6 kg), caught by Jonathan McNamara in the Susquehanna River near Owego, New York, USA on April 15, 2009.
