Scientific Name
Noturus fasciatus

Common Name
Saddled madtom

Biology
Collected from riffle habitats with gravel, cobble, rubble, or slate substrate; mean depth of 0.2 meters (0.1 - 0.3 m), and stream width averaged 13.6 meters (range 8 - 25 m); mean current readings from the 3 capture sites ranged from 0.59 - 0.76 meters per second. Riffles are typically occupied during daylight hours when individuals are likely buried within the interstices of gravel. Based on its small adult size (to 72 mm SL), this species probably lives no longer than 2-3 years. Preserved females contain mature oocytes from late May to late July; females are mature at sizes as small as 44 mm SL (Ref. 56218).
