The Gravel Chub Erimystax x-punctatus (Family Leuciscidae) is an imperiled minnow with a disjunct distribution in Illinois. Due to its affinity for deep, swift flowing water, this species is often difficult to collect with traditional sampling methods and might be overlooked during fish sampling surveys. We performed a status assessment of this rar...

... x-punctatus was found in depths varying from 0.3 to 2.1 m (mean: 0.78 m ± 0.39 m SD; Figure 3) and stream velocities ranging from 0.4 to 2.3 m/s (mean: 1.02 ± 0.45 m/s SD; Figure 4). Depth (t = 0.07, P = 0.53) was insignificant with presence of E. ...
