Central and Eastern U.S. (Clarkson and deVos 1986)
First introduced to the Western U.S. in the early 1900s (Clarkson and deVos 1986)
Most introductions have been associated with escapes from aquaculture operations. Other pathways include bait used for recreational fishing and escapes or releases through the pet trade, landscape ponds, research, and teaching (Adams and Pearl 2007).
Competes with and preys on native species (Ficetola et al. 2007)
