Short description Identification keys | Morphology | Morphometrics

Chrosomus oreas can be distinguished by the possession of the following characters: black stripe along side broken under dorsal fin; large black spots in row along back and along upper side; 64-81 scales on lateral line; pharyngeal 0,5-5,0; snout moderately pointed; mouth slightly subterminal; coloration consists of olive to green-gold above, silver white to red below, bright red below (including lower half of opercle), behind opercle, and at base of dorsal fin in large males, bright silver pectoral and pelvic fin bases, black chin and breast, and yellow fins (Ref. 86798).

Inhabits rocky pools and runs of headwaters, creeks and small to medium rivers (Ref. 86798).

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): 2.0 ±0.00 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
