Species Overview

The bigeye chub is very common in the rivers and large creeks of middle and east Tennessee. They are intolerant of siltation and have been extirpated from much of their former range in the Midwest.



Bigeye chubs have large eyes and short, blunt snouts. They have a relatively large barbel present at the back corner of the mouth and abundant pigmentation above their lateral stripe.

Bigeye chub spawn in late spring to early summer and reach a maximum size of 4-inches. They feed on midge larvae, mayfies, and stoneflies.
