species, which is listed as threatened by the U.S. Fish and Wildlife 
Service. H. cahni was common in this reach of the Clinch River in moder- 
ate current over sand and pea-sized gravel substrate, similar to that de- 
scribed by Masnik (1974) and Burkhead and Jenkins (1982). 
A single collection (two specimens) of the pygmy madtom, Noturus 
stanauli Etnier and Jenkins, was taken in August 1979 at Brooks Island 
(RM 183.7). This site is composed mainly of medium gravel substrate 
and moderate flow, similar to the type locality described by Etnier and 
Jenkins (1980). Two subsequent collecting trips in 1980 at this site pro- 
duced no more specimens. Noturus stanauli , which is restricted to this 
section of the upper Clinch River and to the lower Duck River, is con- 
sidered threatened in Tennessee (Starnes and Etnier 1980). 
The undescribed “duskytail” darter, Etheostoma ( Catonotus ) sp., 
had not been collected from the main Clinch River prior to our study. 
We collected a single specimen at RM 211.1 in May 1980. This site is 
only 0.5 mile below the mouth of Copper Creek (CRM 21 1.6), which is 
known to have a stable population of the duskytail darter. Thus, the 
Clinch River specimen was most likely a transient individual from 
Copper Creek. 
Masnik (1974) reported a total of 75 specimens of the Tippecanoe 
darter, Etheostoma tippecanoe , from six localities in the Clinch River. 
He regarded the apparent rarity of this species in the Clinch River as 
possibly resulting from use of collecting gear (seines) that is ineffective 
for small-size specimens (Masnik 1974). (This theory is also discussed in 
a previous section on E. tippecanoe in the Duck River.) Our study in 
the same general area of the Clinch River produced a total of 170 spec- 
imens at four sites (RM 183.7 to RM 219.4). These results indicate that 
E. tippecanoe is not rare in the Clinch River and that Masnik’s assump- 
tion about the ineffectiveness of collecting gear for this species may be 
correct. 
The sampling site at RM 189.5 (Kyles Ford) yielded the most spec- 
imens of E. tippecanoe , 125; RM 211.1, 183.7, and 219.4 produced 24, 
12, and 9 specimens, respectively. A total of 115 specimens were taken 
in June samples, whereas August, May, and July samples produced 29, 
19, and 7 specimens, respectively. As discussed previously, E. tippeca- 
noe was most abundant in July samples from the Duck River. 
The only populations of E. tippecanoe in Virginia are in the Clinch 
River and Copper Creek. Owing to its restricted range in Virginia, this 
species is considered threatened in that state (Jenkins and Musick 1980). 
Several other species taken from the Clinch River in our study have 
special status. Species listed by Jenkins and Musick (1980) as being of 
special concern in Virginia are: popeye shiner, Notropis ariommus 
(Cope); steelcolor shiner, Notropis whipplei (Girard); river redhorse, 
Moxostoma carinatum (Cope); bluebreast darter, Etheostoma camurum 
(Cope); blueside darter, E. jessiae (Jordan and Brayton); blotchside log- 
perch, Percina burtoni Fowler; and channel darter, P. copelandi (Jor- 
dan). Tangerine darter, Percina aurantiaca (Cope), is listed as in need of
