Range Extent<100 square km (less than about 40 square miles)
Number of Occurrences1 - 5
Rank Reasons
Small population occupies a few springs in Nevada; exotic fishes are the primary threat; excessive cattle grazing is detrimental.
Range Extent Comments
Endemic to Crystal and Hiko springs of pluvial White River drainage in White River system, Pahranagat Valley, Lincoln County, southeastern Nevada. Extirpated from Hiko Spring in 1967; later reintroduced. A refugium population exists in Blue Link Spring far outside the native range.
Occurrences Comments
A few occurrences at most.
Threat Impact Comments
The original population in Hiko Spring was extirpated from the spring and its outflow stream due to habitat modification for irrigation in 1963, and the later introduction of mosquitofish, shortfin mollies, and largemouth bass. The Crystal Spring population has declined to dangerously low levels due to predation and competition with convict cichlids and shortfin mollies; the nonnative species invaded Crystal Spring from Ash Springs. The Blue Link Spring population declined in 1990 when water flow into the reservoir decreased, and the water cooled to unfavorable temperatures. The population is now flourishing after the spring box water supply valves were repaired, and 150 fish from Hiko Spring were introduced to aid in repopulating the spring. The species continues to be threatened by habitat modification, and competition, predation, and parasitism from exotic species. Source: USFWS, Nevada Fish & Wildlife Office.

Habitat changes associated with the presence of cattle may result in increased mortality (Taylor et al. 1989).
Ecology & Habitat

Habitat

Prefers spring heads and quiet waters along outflows.

Reproduction

Spawns in warm summer months; eggs are laid and fertilized one at a time. Incubation lasts 5-7 days (La Rivers 1962).
