United States (contiguous states) country information

Common names: Bonytail
Occurrence: native
Salinity: freshwater
Abundance: scarce (very unlikely) | Ref: Page, L.M. and B.M. Burr, 1991
Importance: | Ref:
Aquaculture: experimental | Ref: Sowka, P.A. and P.E. Brunkow, 1999
Regulations: protected | Ref:
Uses: no uses
Comments: Extremely rare (Ref. 86798). Extant only in Green River, Utah and perhaps in some large impoundments of the Colorado River (Ref. 5723). Several factors contributed to the decline of bonytail populations in the Colorado River. These include habitat alteration produced by reservoir construction and predation by introduced species (Ref. 41720). Little recruitment has been observed for over 30 years (Ref. 41720). Also Ref. 3814. Status of threat: endangered; status same as 1989. Criteria: 1,3, 4 (http://fisc.er.usgs.gov/afs/) (Ref. 81264).

Short description Morfología | Morfometría

Gila elegans can be distinguished from similar species Gila cypha by having terminal mouth, angle along anal fin base continues well above caudal fin, more slender caudal peduncle, smaller hump on nape, usually dorsal fin with 10 rays; and 75-99 scales on lateral line. Breeding males with red lower side and pectoral and anal-fin bases (Ref. 86798).

Biología     Glosario (por ej. epibenthic)

Inhabits flowing pools and backwaters, usually over mud or rock. Streamlined body may suggest occasional occurrence in swift runs (Ref. 86798).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00455 - 0.02896), b=3.03 (2.81 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  2.0   ±0.2 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Muy bajo, población duplicada en un tiempo mínimo superior a 14 años (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (45 of 100).
