Short description Morphology | Morphometrics

Anal soft rays: 7. Oregonichthys crameri can be distinguished by the following characters: caudal peduncle strongly tapering to very narrow; barbel small (sometimes absent) at corner of terminal mouth; rounded snout; dorsal-fin origin over or slightly behind pelvic-fin origin; breast fully scaled; lateral line complete with 35-39 scales; 7 anal-fin rays; pharyngeal teeth 1,4-4,1; body compressed and deepest at dorsal-fin origin; and color consists of olive-tan above, green-brown stripe along back in front of dorsal fin, clusters of large brown-black spots scattered over back and silver side giving salt-and -pepper appearance, darkly outlined scales on back, lines of brown specks on lower side (Ref. 86798).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates in FishBase (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.2 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (13 of 100) .
