The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Taxonomy: available through www.itis.govITIS logo

Identification: Becker (1983); Smith (1985); Page and Burr (1991); Jenkins and Burkhead (1994). This species is represented by two subspecies, F. d. diaphanus and F. d. menona.

† Populations may not be currently present.

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: 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.

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).
