Abstract

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 rare species with methods that target benthic-dwelling fishes by sampling at 50 sites throughout the species range. Our data showed that E. x-punctatus is still extant throughout the Rock River drainage and the mainstem Vermilion River (Wabash River drainage), and that this fish showed a strong attraction to high velocity areas over clean, rocky substrates.
