Concept Reference Code: B91ROB01NAUS
Name Used in Concept Reference: Phoxinus oreas
Taxonomic Comments: This species formerly was included in the genus Phoxinus. Based on patterns of genetic variation, Strange and Mayden (2009) reassigned all North American Phoxinus species to the genus Chrosomus.

A hybrid Phoxinus oreas x Semotilus atromaculatus has been recorded in the James River drainage, Virginia (Copeia 1992).

Riverine Habitat(s): CREEK, High gradient, MEDIUM RIVER, Moderate gradient, Pool
Special Habitat Factors: Benthic
Habitat Comments: Habitat includes rocky pools and runs of headwaters, creeks, and small to medium rivers (Page and Burr 2011). This dace is typical of small, cool to warm, clear to often turbid, sandy to rocky streams (Lee et al. 1980). Spawning has been observed in association with Nocomis nests.

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.
