Noturus miurus Jordan, 1877
Common name: Brindled Madtom
Taxonomy: available through www.itis.govITIS logo

Identification: Trautman (1981); Smith (1985); Page and Burr (1991); Etnier and Starnes (1993); Pflieger (1997).
Size: 13 cm.
Native Range: Lower Great Lakes drainages in Ontario and New York, southwest through most of the Ohio River basin and lower Mississippi River basin (west to eastern Kansas and Oklahoma; Pearl River and Lake Pontchartrain drainages on central Gulf Slope in Mississippi and Louisiana (Page and Burr 1991).

Nonindigenous Occurrences: Introduced into the Mohawk River in New York (Mills et al. 1997). Specimens have been taken at Lock 7 near Schenectady and at Lock 9 at Rotterdam Junction (Smith 1985; Mills et al. 1997). Smith (1985) mapped another location on the Mohawk near Little Falls, where it is presumably also introduced. The eastern range expansion is relatively recent, Lee et al. (1980 et seq.) reported it only as far east as Oneida Lake.

† Populations may not be currently present.
Means of Introduction: Canal connection. Probably gained access from Lake Ontario systems in western New York to the Mohawk River via the Erie Canal (Smith 1985; Mills et al. 1997).
Status: Reported in New York.
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: None.

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.
