Bloodfin Darter | Nothonotus sanguifluus

Status: IUCN: Least Concern

Threats: Impoundments, mining, and sedimentation.

CFI Status: Propagated at CFI in 1994 to develop propagation protocols as a surrogate species for Boulder Darters. (What do these terms mean?)

Native Range: Middle Cumberland River drainage from Rockcastle River, KY to Caney Fork, TN

Spawning Habitat Preferences: Spring spawners in small to medium streams with high flow and rocky substrates; lay eggs in crevices of large rocks or boulders

Fun Fact: In our experience, the Bloodfin Darter can change its color more quickly than nearly any other fish we work with. When a mature male is uncovered during a survey, he can change from a jet-black fish with blood-red fins and spots to a largely brown little darter in just over a second. This remarkable survival adaptation has been a source of frustration for those wishing to capture images of their stunning beauty.
