The Largemouth Bass is also stocked in Puerto Rico (Erdsman 1984; Lee et al 1983).

Means of Introduction: This species has been an important sport fish for many years and as such has been stocked widely in areas where it is nonindigenous. Intentional stocking for sportfishing.

Status: Established in most locations.  Expanding its range in inland locations in the Great Lakes basin.

Impact of Introduction: Introduced bass usually affect populations of small native fishes through predation, sometimes resulting in the decline or extinction of such species (Minckley 1973). Species that have suffered such effects include relict dace Relictus solitarius, Clover Valley speckled dace Rhinichthys osculus oligoporus, Independence Valley tui chub Gila bicolor lethoporus (U.S. Fish and Wildlife Service 1985b), a distinct population of Gila chub G. intermedia, Monkey Spring pupfish Cyprinodon sp. (Minckley 1973), White River springfish Crenichthys baileyi, Pahranagat roundtail chub Gila robusta jordani (U.S. Fish and Wildlife Service 1985b), Owens pupfish Cyprinodon radiosus (Miller and Pister 1971), wild brook trout Salvelinus fontinalis (Boucher 2003), and White River spinedace Lepidomeda albivallis (U.S. Fish and Wildlife Service 1994e). Jenkins and Burkhead (1994) speculated that introduced Largemouth Bass may have contributed to the demise of an isolated population of trout-perch Percopsis omiscomaycus in the Potomac River in Virginia and Maryland. Introduced predatory centrarchids are likely responsible for the decline of native ranid frogs in California, California tiger salamander Ambystoma californiense populations (Hayes and Jennings 1986; Dill and Cordone 1997), and the Chiricahua leopard frog Rana chiricahuensis in southeastern Arizona (Rosen et al. 1995). In Squaw Creek Reservoir in northcentral Texas, introduced Florida largemouth intergrade with native northern largemouth (Whitmore and Hellier 1988). Nonnative predators, including Largemouth Bass, have been shown to reduce the abundance and diversity of native prey species in several Pacific Northwest rivers (Hughes and Herlihy 2012). The presence of Largemouth Bass, along with other introduced piscivores, reduced the richness of native minnow communities in Adirondack lakes (Findlay et al. 2000).

Remarks: This account includes introductions of both subspecies M. s. salmoides, the northern Largemouth Bass, and M. s. floridanus, the Florida Largemouth Bass. For instance, both subspecies have been introduced into Nevada (Deacon and Williams 1984). Tyus et al. (1982) gave a distribution map of the this species in the upper Colorado basin. MacCrimmon and Robbins (1975) showed a map depicting this species' native and introduced range. Jenkins and Burkhead (1994) reported the largemouth as introduced into the Roanoke drainage in Virginia. Recently prehistoric bones of M. salmoides were discovered near the Roanoke River in Roanoke, Virginia, indicating that the species is native there (Jenkins, personal communication).

Introduced Florida Largemouth Bass are known to hybridize with native populations of northern Largemouth Bass (Whitmore and Hellier 1988), with introgression of Florida bass genes into populations occurring rapidly (Gelwick et al. 1995) and dispersing away from original introduction/stocking sites (Ray et al. 2012).
