|Scientific Name:||Etheostoma zonistium|
|Species Authority:||Bailey & Etnier, 1988|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Smith, K. & Darwall, W.R.T.|
|Facilitator/Compiler(s):||Hammerson, G.A. & Ormes, M.|
Somewhat small extent of occurrence, but listed as Least Concern in view of the large number of subpopulations, apparently stable trend, and apparent lack of major threats.
|Range Description:||Range includes tributaries of the lower Tennessee River system of western Tennessee and Kentucky, northwestern Alabama, and northeastern Mississippi, upstream to Bear Creek system; confined to western tributaries except in Land Between the Lakes, Kentucky, and Hardin County, Tennessee; also Spring Creek of upper Hatchie River system in western Tennessee, and Hubbard Creek (extreme upper Sipsey River system, Alabama (Bailey and Etnier 1988, Page and Burr 2011).|

This species is represented by a large number of occurrences (subpopulations). Reported from at least 50 localities.
Total adult population size is unknown but presumably exceeds 10,000. This species is common (Page and Burr 2011).
Trend over the past 10 years or three generations is uncertain but likely relatively stable (Warren et al. 2000).
|Habitat and Ecology:||Habitat includes sand- and gravel-bottomed pools of headwaters, creeks, and small rivers (Page and Burr 2011); Coastal Plain streams with low gradients and fine gravel to sandy substrates; upland habitats (Black Warrior River system) in clear cool streams with abundant areas of boulder and bedrock substrates; also (in Hatchie River system) cool spring-fed streams with silt and fine sand substrates in areas of swampland forest (Bailey and Etnier 1988). Eggs are laid probably on submerged logs and snags (Bailey and Etnier 1988).|
|Major Threat(s):||No major threats are known.|
|Conservation Actions:||Currently, this species is of relatively low conservation concern and does not require significant additional protection or major management, monitoring, or research action.|
