The Desert Dace

Desert Dace is a small Nevada minnow adapted to thermal springs. Its deep body, dark lips and hard jaw coverings distinguish a fish living in water much warmer than many other western minnows tolerate.

Identification

The body is relatively deep with a blunt snout and small mouth set slightly below the tip. Both jaws have a hard covering, and the lips are dark. Olive, green, brassy yellow and silver tones occur across the body.

Warm Springs

Desert Dace is associated with the springs and outflows of Soldier Meadows. The temperature it can tolerate is a documented limit, not a recommendation to make all its habitat that warm. Conditions can differ along a spring outflow.

Size and Conservation

The maximum length is 7.7 centimeters including the tail, with a smaller common reference around 5.1 centimeters. Changes to spring flow and habitat for irrigation or other uses are important conservation concerns. A small occupied area makes the condition of individual spring channels consequential.

Tolerance Is Not a Target

Surviving unusually warm water does not mean a fish benefits from further heating. Preserve the natural variation within its spring habitat.
