The shoal chub (Macrhybopsis hyostoma) is a species of freshwater ray-finned fish belonging to the family Leuciscidae, the shiners, daces and minnows. It occurs in Mississippi River drainages from eastern Ohio to southern Minnesota and Nebraska south to Louisiana. Its preferred habitat is sand and gravel runs (shoals) of small to large rivers.
In their breeding condition, males develop horny nuptial tubercles on the pectoral fins, and both sexes produce a sandpaper-like texture which is present across the surface of the head and much of the body.

A blank area on the dot layer usually means nobody sampled there, not that the fish is absent. Turn on “every survey site” to see where the survey looked.
The USGS stream survey caught it at 60 of its sites, in 8 states. That survey and the GBIF records are two different counts of two different things, so the site keeps them apart.
