The sub-terminal mouth is oblique with equal jaws, and a barbell is on the posterior tip of the lower jaw. White and Orth (2014) classified Clinch Dace as a nest associate of Central Stoneroller (Campostoma anomalum) and Creek Chub (Semotilus atromaculatus) and observed spawning from mid-May to July at a water temperature of approximately 15 C. Summary 2 Eastern blacknose dace (Rhinichthys atratulus) is a species of ray-finned fish in the genus Rhinichthys.Its name originates from the Old French word "dars" which is the nominative form of the word "dart" in reference to their swimming pattern. Spawning takes place from May through July, when males build a nest of gravel and guard a well-defined territory. After spawning, he carries small stones in his mouth and deposits them on top of the nest. [4] The snout is relatively long and they have a slightly sub-terminal mouth. One study yielded spawning observations in two creeks over 2 d (White and Orth, 2014b).

Western blacknose dace have tan to dark brown backs, lighter sides, and cream colored undersides. Blacknose Dace spawn in spring, May to June, choosing a shallow, sandy or gravelly riffle. In small streams in urban and suburban areas, I suspect that hydrant flushing (with chlorine, chloramine) during low streamflow periods in warmer weather may be more damaging that road salt runoff in winter.
