Ecology & Life History
Basic Description: A small fish (minnow).
Reproduction Comments: Spawns in spring. Eggs hatch in a week to 10 days. Sexually mature at age 1-2 (Becker 1983).
Ecology Comments: A schooling species (Becker 1983).
Habitat Type: Freshwater
Non-Migrant: N
Locally Migrant: N
Long Distance Migrant: N
Riverine Habitat(s): CREEK, Low gradient, Pool
Lacustrine Habitat(s): Deep water, Shallow water
Special Habitat Factors: Benthic
Habitat Comments: Habitat includes small, clear, sluggish weedy creeks or small rivers with sand, gravel, or mud bottom overlain with organic sediment; this species also is common in cool, stained or acid waters of boggy streams, ponds, and lakes, and it is common in overflow ponds near rivers. Spawning occurs among vegetation in shallows and in flooded marshes. Eggs are scattered on vegetation and on the bottom (Becker 1983).
Adult Food Habits: Herbivore, Invertivore
Immature Food Habits: Herbivore, Invertivore
Food Comments: Eats algae, phyto- and zooplankton, benthic invertebrates, surface drift, bottom ooze (Becker 1983).
Phenology Comments: Winters in pools and deep runs under shelter or buried in debris (Becker 1983).
Length: 10 centimeters
Economic Attributes Not yet assessed
Management Summary
Biological Research Needs: Little is known of the breeding biology of this species (B73SCO01NAUS).
Population/Occurrence Delineation
Group Name: Small Cyprinids

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on evidence of historical presence, or current and likely recurring presence, at a given location. Such evidence minimally includes collection or reliable observation and documentation of one or more individuals (including eggs and larvae) in appropriate habitat.
Separation Barriers: Dam lacking a suitable fishway; high waterfall; upland habitat. For some species (e.g., slender chub), an impoundment may constitute a barrier. For others (e.g., flame chub) a stream larger than 4th order may be a barrier.
Separation Distance for Unsuitable Habitat: 10 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: Data on dispersal and other movements generally are not available. In some species, individuals may migrate variable distances between spawning areas and nonspawning habitats.

Separation distances (in aquatic kilometers) for cyprinids are arbitrary but reflect the presumption that movements and appropriate separation distances generally should increase with fish size. Hence small, medium, and large cyprinids, respectively, have increasingly large separation distances. Separation distance reflects the likely low probability that two occupied locations separated by less than several kilometers of aquatic habitat would represent truly independent populations over the long term.

Because of the difficulty in defining suitable versus unsuitable habitat, especially with respect to dispersal, and to simplify the delineation of occurrences, a single separation distance is used regardless of habitat quality.

Occupied locations that are separated by a gap of 10 km or more of any aquatic habitat that is not known to be occupied represent different occurrences. However, it is important to evaluate seasonal changes in habitat to ensure that an occupied habitat occurrence for a particular population does not artificially separate spawning areas and nonspawning areas as different occurrences simply because there have been no collections/observations in an intervening area that may exceed the separation distance.
