General Information

The spinedace is described as a small (about 4 inches) silvery minnow. There are minimal differences between the sexes. The pectoral fin on males is larger than females, but both males and females are relatively the same size. During breeding season the bases of paired fins in males has been described as turning an intense reddish-orange, or a wash of weak yellow or orange. Females are also reported developing a watery yellowish or reddish-orange at the bases of the paired fins. Generally, the fish has an olivaceous, bluish, or lead gray back and olivaceous upper sides. There are nearly vertical dark lines that extend dorsally from the midside and have a silvery tint. There are irregularly distributed, fine, black puncticulations giving a pepper-like effect.

Habitat Requirements

Has been found in flowing stream sections where substrates consists of sand, gravel, rocks, boulders, some silt and bedrock. Water color can vary from greenish brown to clear. Predominately in open pools with undercut banks and/or boulders for cover. Water temperatures in occupied habitats ranged from 58 to 78 degrees Fahrenheit. Given the fluctuating nature of the Southwest, the spinedace is adapted to adjust to different physical conditions.

Food Habits

Spinedace are omnivorous, and food items include chironomid larvae, other dipterans, filamentous green algae, and crustaceans.

Movement / Home Range

Historically, and currently found between 4,000 and 8,000 feet in elevation. Currently the range of the species is confined to disjunct locations within the East Clear Creek Watershed, Chevelon Creek, the upper LCR (including Nutrioso and Rudd Creeks), and Silver Creek. Critical habitat includes 18 miles of East Clear Creek, 8 miles of Chevelon Creek, and 5 miles of Nutrioso Creek (52 FR 35034).

Reproductive Strategy

Eggs are presumably randomly deposited over the stream bottom or on aquatic vegetation or other debris. Spinedace are late-spring to early-summer spawners, although some females have been found to contain mature eggs as late as October.

Other

Identified threats are habitat fragmentation, habitat loss, drought, urban growth, mining, timber harvest, road construction, livestock grazing, and other watershed disturbances (e.g., road construction and maintenance, recreational development and usage, fire management, and inter-basin water diversions), and predation by non-native piscivorous fish/crayfish.
