The Kanawha darter (Etheostoma kanawhae) is a rare freshwater fish species found only in the New River drainage.  Here a brightly colored male searches for a female during spawning season in Helton Creek, North Carolina.

Research Interests

My research compares the habitat preferences of three closely related species of non-game fish in the New and Elk river drainages. This is particularly important because one of the species, variegate darter Etheostoma variatum, has recently been introduced into the New River drainage where it threatens to compete with two of the native and already imperiled New River species, candy darters E. osburni and Kanawha darters E. kanawhae. Other objectives of my research include documenting how habitat preferences change with ontogeny and season, as well as providing management recommendations for the physical habitat and temperature requirements for candy darters that may ultimately lead to the recovery of the species in Virginia.
