Etheostoma spilotum

The Cumberland Plateau darter (Etheostoma spilotum) is a species of darter endemic to the eastern United States, where it occurs in the upper Kentucky River drainage in Kentucky. It inhabits rocky riffles and pools of headwaters, creeks and small rivers. This species can reach a length of 12 cm (4.7 in). Habitat includes upland creeks and streams, generally in headwaters, but juveniles and sometimes adults are also sometimes found in larger streams; generally this darter occurs in slow to moderate current in cool, sluggish pools or areas above and below riffles (avoids swift currents) over bedrock, rubble, cobble, and pebble, often interspersed with sandy areas. Spawning occurs apparently in riffles in water about 5–15 cm deep or under or near rocks in raceways. Conservation Fisheries, Inc. (CFI) reported that CFI, in cooperation with Kentucky Department of Fish & Wildlife, developed captive propagation protocols for reintroduction of Etheostoma spilotum into streams within its native range to restore populations that have been extirpated. Reintroduction sites will be chosen where habitat conditions are suitable and there is some level of protection (e.g., within wildlife management area or national forest boundaries). Survivability and movement patterns of released fish will be assessed through mark-recapture methods and through periodic monitoring using non-invasive methods, such as visual census techniques. Accordingly, 110 juvenile Etheostoma spilotum were released to Sugar Creek, Kentucky in an effort to restore the species to a stream (near the source population) where the species had apparently been extirpated, but which exhibited currently suitable habitat.
