Nonindigenous Occurrences: This species was stocked in ponds in Windham, New Hampshire (Scarola 1973). It was collected from the upper Ohio and Beaver river systems in far western Pennsylvania, apparently in the late 1930s and early 1940s (Raney 1938, cited in Trautman 1981). It has also been collected in Pennsylvania from the Juniata River in Blair County; Sandy Run, a tributary of the Little Juniata; in Conowingo Pond in Lancaster County (Denoncourt et al. 1975a), the Schuylkill and Brandywine drainages of the lower Delaware, and the Lower Susquehanna (Denoncourt et al. 1978).

Means of Introduction: This species was introduced into ponds in New Hampshire, apparently via bait bucket release (Scarola 1973). It was transferred to far western Pennsylvania from the Delaware River drainage of the eastern part of the state (Raney 1938, cited in Trautman 1981), possibly as a baitfish. The other collections in Pennsylvania are believed to be bait bucket introductions (Denoncourt et al. 1975a, 1978).

Status: Previously established or locally established in New Hampshire and Pennsylvania (Scarola 1973; Trautman 1981). Denoncourt et al. (1975a) reported only two specimens from Sandy Run, and one specimen from the Juniata River. Established in the lower Susquehanna and Delaware drainages (Denoncourt et al., 1978).

Impact of Introduction: Unknown.

Remarks: None.
