Description synthétique Morphologie | Morphométrie

Rayons mous dorsaux (Total): 8; Rayons mous anaux: 8. Previously thought to be of hybrid origin and similar to parental Gila robusta and G. intermedia. Dorsal and anal fins with 8 rays; lateral line with 71-90 scales, usually fewer than 80; first gill arch with 10 or more rakers; and often with diffuse stripes on dark gray or brown side, dark fin membranes (Ref. 86798).

Biologie     Glossaire (ex. epibenthic)

Inhabits pools and undercut banks of headwaters, creeks and small rivers. Maximum length is presumably about 38 cm TL (Ref. 86798).

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [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):  2.0   ±0.2 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100).
