Invasion
Invasion Description
1st Record: NY/Erie-Canal-Hudson River (1902, Smith and Lake 1990; Mills et al. 1997; Daniels et al. 2005) The Largemouth and Smallmouth Basses (Micropterus dolomieu and M. salmoides) were widely lumped as 'Black Basses' and frequently confused. The first definite record for M. dolomieu in the Hudson Basin is from 1902 Both species may have been introduced by the Erie Canal, or stocked later on (Mills et al. 1997; Daniels et al. 2005)
Geographic Extent

Regional Impacts
| Ecological Impact | Predation | |
| Impacts of Smallmouth Bass (Micropterus dolomieu) in East Coast estuaries are probably limited by the low abundance of this primarily freshwater river species, especially in the Mid-Atlantic states, but it is an important predator in upland rivers (Jenkins and Burkhead 1993) and can affect anadromous fish populations. Smallmouth Bass is considered a major predator in the Hudson River (Mills et al. 1997). | ||
