Means of Introduction: White perch (M. americana) invaded the native range of yellow perch via the Chicago Shipping Canal from the Great Lakes, where it is also introduced. It gained access to the Great Lakes via the Erie Canal system in New York (see account for white perch).
Status: Established in the middle Illinois River.
Impact of Introduction: Hybridization and competition may represent another threat to the already dwindling yellow bass of that region (Irons et al. 2002).
