Blackside Dace (Chrosomus cumberlandensis)

Description: 

Blackside Dace are a federally threatened species found in the upper Cumberland River Drainage above Cumberland Falls. Coal-mining activities in this area have caused population declines. Like other members of the Redbelly Dace group, male Blackside Dace develop bright breeding colors in the early spring with yellow fins, red bellies, and a golden back.
