Bigmouth Buffalo was first reported in eastern Lake Erie in the 1990s, although it has been present in other parts of the lake for several decades. It is nonnative in Lake Erie. Little is known about its favored habitats except that adults are seen in spawning condition near Dunkirk. It has been caught in Lake Ontario near Bay of Quinte, which is on the Canadian side of the lake.
