Short description Morphology | Morphometrics

Chrosomus cumberlandensis can be distinguished by having the following characters: two dusky stripes along side converge on caudal peduncle, coalesce into wide black stripe on large male; back and upper side with many black specks; 66-81 scales on lateral line; pharyngeal teeth 0,5-5,0; olive to green-gold above, silver white to red below; large male bright red below, behind opercle, and at base of dorsal fin; bright silver pectoral and pelvic fin bases, yellow fins; body moderately compressed; pointed snout and slightly subterminal mouth (Ref. 86798).

Biology     Glossary (e.g. epibenthic)

Inhabits rocky pools of headwaters and creeks. Usually found along undercut banks, near large rocks or among detritus (Ref. 86798). Feeds on attached algal growth and aquatic insect immatures (Ref. 10294).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.6   ±0.26 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (tm=1; tmax=4).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
