Reproductive Timing Of Erimystax Insignis (Blotched Chub) In The Flint River Of North Alabama, Bruce Stallsmith, Josh Mann, Candice Allen

Southeastern Fishes Council Proceedings

Important details of the reproductive ecology of many freshwater fishes of the species-rich southeastern United States are still poorly known. One such species is Erimystax insignis (Blotched Chub), whose range includes the Tennessee River drainage in northern Alabama, USA. To determine timing and patterns of reproductive effort, collections were made monthly of as many as 30 individuals from August 2011 through July 2012 from a 14 km stretch of the Flint River in Madison County, Alabama.
