Means of Introduction: Spotfin Shiners have been stocked intentionally as a forage fish in Nebraska (Bouc 1987). It most likely entered Smith Mountain Lake, Virginia, from the nearby New drainage, possibly transferred with white bass from Claytor Lake (Jenkins and Burkhead 1994). The method of introduction into other areas has not been reported although introduction via bait bucket releases is a possibility in some areas.
Status: Established in parts of Nebraska (Bouc 1987; Lee et al. 1980 et seq.). Established and abundant in Smith Mountain Lake, Virginia; reported from Sherando Lake, Virginia (Jenkins and Burkhead 1994). Reported, probably established, in Iowa outside its native range (Lee et al. 1980 et seq.).
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
