Nonindigenous Occurrences: The species is established in Silvio O. Conte National Fish and Wildlife Refuge, Franklin County, Massachussetts (USFWS 2005).  The eastern subspecies F. d. diaphanus was introduced into Lake Erie, the Little Miami drainage, and several areas in the upper Ohio River basin in Ohio, and into the Ohio and Beaver River drainages (Raney 1938, cited in Trautman 1981), the Monongahela drainage (Hocutt et al. 1986), and the Youghiogheny River (Hendricks et al. 1979) in Pennsylvania. This species was accidentally stocked in Lake Andes, South Dakota, by a federal hatchery stocking of largemouth bass (Bailey and Allum 1962). Fundulus diaphanus is known from Baskett Slough, and the Columbia, Lewis and Clark, and Willamette rivers, Oregon (Bond 1994).  It is established in Big McNary Lake on Sauvie Island in the Columbia River, Oregon (Logan 1994). It also has been reported from the Columbia and Kalama Rivers, and Lake Sacajawea, Washington (Fletcher, personal communication).

Means of Introduction: The fish was transplanted to parts of eastern Ohio and western Pennsylvania from the Delaware River drainage of eastern Pennsylvania (Raney 1938, cited in Trautman 1981). A population in Clough Creek, Ohio, was likely the result of an aquarium release (Trautman 1981). One lake in South Dakota was stocked accidentally with largemouth bass (Bailey and Allum 1962). The species was introduced into other areas through unknown means; possibly bait bucket releases.

Status: Established in Ohio, Pennsylvania, South Dakota, Oregon, and Washington. In Pennsylvania, known from the Ohio and Beaver drainages and established in the Youghiogheny.

Impact of Introduction: Unknown.

Remarks: According to Bond (1994), the Oregon introduction involved the subspecies Fundulus diaphanus diaphanus; however, Li (personal communication) reported it as being the western subspecies F. d. menona. The Washington record was also reported as F. d. menona (Fletcher, personal communication).

Voucher specimens: Ohio (OSM 33514, 13865).
