Down arrow Species Information
Size 280mm or 11" SL. Find near, nearer or same sized spp.
Identification One of the easier ictalurids to recognize. It has a relatively dark body with many small bold white spots which no other bullhead has. There is a dark oval blotch at the base of the dorsal fin. The upper jaw is longer than the lower jaw. Caudal fin and the relatively short rounded anal fin have a distinct narrow black margin. Not to be confused with the southern mottled form of Ameiurus nebulosus.
Sexing Females are much fuller bodied during breeding season. This occurs during early spring.
General Remarks A spectacular looking fish. A great catfish to keep for those looking for a smaller predatory fish. In the wild, it has a limited distribution and is not commonly found even in its own range.
