Ecology: In its native range in the Upper Niagra River, Notropis atherinoides juveniles are more often found in natural habitat (e.g. marshes) than developed habitat (e.g. seawalls; Cochran 2017). Cochran (2017) also found that larvae recruited to sampling gear in July and August. This species is a key forage species in its native range (Cochran 2017).
Means of Introduction: This species was stocked as forage in Jennings Randolph Reservoir, Maryland (Christmas, personal communicaton), Lake McConaughy, Nebraska (Bouc 1987), and in certain Wyoming reservoirs (Hubert 1994). Its presence in two reservoirs in New York may be due either to bait bucket releases or to movement through the Old Chenango Canal (Snelson 1968; Smith 1985). Snelson (1968) also hypothesized that the widespread occurrence of this species in the Mohawk-Hudson system of New York may have been a result of dispersal through the Erie Canal system. If records from West Virginia represent introductions, the method of entry was likely by way of bait bucket releases. The species probably was brought to Maine illegally as a baitfish; however, information on the location and exact date of its first occurrence in the state has been lost (Kircheis 1994). It was introduced into Willard Bay Reservoir in Utah in 1983 (Sigler and Sigler 1987). The Emerald Shiner has been stocked for forage in many Colorado reservoirs (Colorado Division of Wildlife).
Status: Introduced populations considered established in Maine, Maryland, Massachusetts, Nebraska, New York, Utah, West Virginia, and Wyoming.
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.
