Common Name: margined madtom
Taxonomy: available through 
Identification: The margined madtom has a light cream-colored belly, a light brown to grey back and chin barbells. There are no blotches or saddle marks on this fish's back and sides as found on other madtoms. Its dorsal and caudal fins are light brown with black edges, its adipose fin is attached along the length of the body and is continuous with the square caudal fin. Smith (1985); Page and Burr (1991); Jenkins and Burkhead (1994).
Size: 15 cm.
Native Range:
Atlantic Slope from the Delaware drainage, New York, to upper Altamaha River drainage, Georgia; upper Kanawha (New) River system, Virginia and North Carolina; upper Monongahela River system, Pennsylvania and Maryland (Page and Burr 1991).
Nonindigenous Occurrences: This catfish has been introduced outside, or possibly outside, its native range, in the Monongahela drainage, Maryland (Lee et al. 1984; Jenkins and Burkhead 1994); Crooked Springs Brook in the Merrimack drainage, Massachusetts (Hartel 1992; Hartel et al. 1996); Lake Gogebic (=Lake Clark), Michigan (Taylor 1969; Emery 1985); the Merrimack River drainage, New Hampshire (Taylor 1969; Scarola 1973; Schmidt 1986; Hartel 1992); the Finger Lakes, Mohawk, Oswego, and St. Lawrence drainages, New York (Emery 1985; Jenkins and Burkhead 1994); the Watauga River, Tennessee drainage, North Carolina (Starnes and Etnier 1986; Menhinick 1991; Page and Burr 1991; Etnier and Starnes 1993; Jenkins and Burkhead 1994); the Monongahela drainage, Pennsylvania (Cooper 1983; Hocutt et al. 1986; Jenkins and Burkhead 1994); the Watauga River above Watauga Reservoir, Tennessee (Etnier and Starnes 1993); the North Fork Holston River, Virginia (Page and Burr 1991; Etnier and Starnes 1993; Jenkins and Burkhead 1994); and the Monongahela River, West Virginia (Hocutt et al. 1986; Jenkins and Burkhead 1994; Stauffer et al. 1995).
Ecology: Gutowski and Stauffer (1993) found that margined madtoms preferentially feed on baetid, chironomid, and simuliid larvae. Locomotory activity levels increased after dusk as is common for most species of madtom. According to catch per effort data, these fish were most active near midnight (Gutowski and Stauffer 1993).
Means of Introduction: Many of these occurrences may have been the result of bait bucket introductions (Taylor 1969; Jenkins and Burkhead 1994).
Status: Established in most waters where introduced.
Impact of Introduction: Unknown
Remarks: Taylor (1969) and Jenkins and Burkhead (1994) discussed native and possible nonnative distribution. Hocutt et al. (1986) listed this species as native but possibly introduced into the Monongahela drainage.
