The desert dace (Eremichthys acros) is a rare cyprinid fish known only from the warm springs and creeks of Soldier Meadow in western Humboldt County, Nevada, USA. It is the only member of the monotypic genus Eremichthys. [2] . The species is also notable for its ability to live in waters as warm as 38 °C (100 °F).

Desert dace is a small olive green and silver fish and is found in several thermal springs and outflows in Soldier Meadows in Humboldt County, Nevada. It has the highest temperature tolerance of any minnow in western North America and can live in waters as warm as 104 degrees Fahrenheit.

The desert dace inhabits thermal springs and their outflows, including small irrigation ditches, where waters are warmer than 67 ° F (19 ° C). Water temperature appears to be a major factor controlling the distribution of desert dace within a spring system.

The desert dace (Eremichthys acros), a rare desert fish, is found only in Soldier Meadows’ hot spring outflows north of Mud Meadow Reservoir. The desert dace is a monotypic genus federally listed as threatened. A rare plant, the basalt cinquefoil (Potentilla basaltica), also …

Eremichthys acros is distinguished by the following characters: absence of barbel or frenum; dorsal fin origin behind pelvic-fin origin; complete or incomplete lateral line with 68-78 scales; anal fin with 7-8 rays; pharyngeal teeth 0,5-4,0; hard sheath on upper and lower jaws; small, slightly subterminal mouth; black lips; short blunt snout; de...

2004年6月6日 · Desert dace are thermal endemics, and restricted to a series of less than 10 small springs and their associated outflows in Soldier Meadow, an area tributary to the Black Rock Desert, northwest Nevada, USA (41° 22' N, 119° 11' W). They have been isolated there for a long but indeterminate period.

Desert dace is a small desert fish endemic to thermal springs found in Soldier Meadows, Nevada. During the time of listing, habitat alterations associated with water diversion and irrigation channels (Factor A) were the primary threat to the species as well as invasive species
