Range and Identity
Erimystax dissimilis is recorded across the Ohio basin from western New York toward northern Indiana and south toward Alabama. A single Lake Erie record is also noted. One lake observation should remain identifiable as such rather than becoming a claim of widespread Great Lakes occupancy.
Habitat and Behavior
Adults use riffles, runs and current-swept pools in small to large clear rivers. Gravel and rubble are characteristic bottoms. The shared feature is flowing water over coarse material, even though depth and channel form differ among the occupied positions.
Food and Life History
The reported maximum is fourteen centimeters total length; 8.8 centimeters is a common reference. Foods include periphyton, the growth attached to submerged surfaces, plus midge, mayfly and caddisfly larvae. The account does not establish a fixed seasonal migration.
Field Note
Describe the flow through a pool rather than labeling all pools as still water. Current-swept pools are explicitly part of this chub's recorded habitat.
