Description synthétique Morphologie | Morphométrie

Rayons mous anaux: 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).

Occurs in sluggish sand- and gravel-bottomed pools and backwaters of creeks and small rivers. Often found in vegetation and sometimes in ponds and impoundments (Ref. 86798).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): 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), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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