Reproductive Biology of Syntopic Blackside Dace and Southern Redbelly Dace in Two Kentucky Streams
… is known that the federally threatened Blackside Dace and common Southern Redbelly Dace are ecologically similar species, occur syntopically in Kentucky in the upper Cumberland River basin, and utilize some of the same host species for nest sites; however, it is unclear if the two fish species are …

Population Fragmentation and Genetic Diversity of Chrosomus sp. cf. saylori (Clinch Dace)
Clinch Dace (Chrosomus sp. cf. saylori) is a newly recognized species of minnow with a restricted distribution in southwestern Virginia. Field sampling and genetic analysis support the hypothesis that Clinch Dace populations are small and fragmented. Analysis of neutral genetic markers shows that …

Distribution and Population Characterization of Clinch Dace (Chrosomus sp. cf. saylori) in the Upper Clinch River System, Virginia
The Clinch Dace Chrosomus sp. cf. saylori is a species of minnow known from only two counties in Virginia. Prior surveys established the species' presence in just eight tributaries to the upper Clinch River. A management plan, which should include both population monitoring and habitat restoration, …

Ecology of Glacial Relict Fishes in South Dakota's Sandhills Region
… priorities. South Dakota populations of three dace species (northern redbelly dace Chrosomus eos, finescale dace Chrosomus neogaeus, and pearl dace Margariscus margarita) are relict of Pleistocene Glaciation and are isolated from the northern core of their distribution, but little information …

A Post-Restoration Assessment of the Fishes and Macroinvertebrates of Mill Branch, Knox County, Kentucky, with Emphasis on the Blackside Dace (Chrosomus cumberlandensis)
… project for the federally threatened blackside dace, Chrosomus cumberlandensis (Starnes and Starnes), was initiated in fall 2005 on Mill Branch, a small headwater stream located in the Upper Cumberland River basin, Knox County, Kentucky. The lower 700 meters of Mill Branch were restored through …

Response of brook char (Salvelinus fontinalis) and blacknose dace (Rhinichthys atratulus) to acidic episodes in three headwater streams within the Shenandoah National Park, Virginia
… Brook char (Salvelinus fontinalis) and blacknose dace (Rhinichthys atratulus) were the only two species common to all watersheds. Both species used pools more than riffles (P<0.05). Brook char density in pools increased with ANC (P<0.05), ranging from 13.1 to 40.1 fish/100m². Blacknose dace …

The efficacy of back calculation methods for determining length at age data and the use of such data to determine growth standards, national growth patterns and recruitment dynamics of roach (Rutilus rutilus (L.)), dace (Leuciscus leuciscus (L.)) and chub (Leuciscus cephalus (L.)) in UK rivers
… curves were originally produced for roach, dace, chub and bream (Hickley and Dexter 1979) and later expanded to include pike (Hickley and Sutton 1984). Habitat rehabilitation (Quinn 1994) and water quality improvements (Environment Agency 2001; 2006) are among a number of factors that have …

Distribution, ecology, and reproductive biology of the orangefin madtom (Noturus gilberti)
… madtoms included chubs, mountain redbelly dace, rosyside dace, crescent shiners, and crayfish; only Roanoke darters were considered positive associates. Sand and silt levels were significantly lower at sites with N. gilberti, while percentage of small cobble, local gradient, and depth were …

A quantitative evaluation of environmental enrichment for stream fish at the Tennessee Aquarium
… behaviors of tangerine darters and Tennessee dace in response to increasing temperature. If seasonal mimicking functions as environmental enrichment, I expected both species to exhibit behaviors consistent with those observed in wild populations. Tennessee dace became more active. Tangerine …
