North America: Utah Lake and its tributaries in Utah, USA. Two subspecies were recognized: Chasmistes liorus liorus from Utah Lake; and Chasmistes liorus mictus may have arisen as a hybrid between Chasmistes liorus liorusand Chasmistes ardens and replaced the original form of Chasmistes liorus.
Length at first maturity / Size / Вес / Возраст
Maturity: Lm 46.5, range 44 - 49 cm
Max length : 60.0 cm TL самец/пол неопределен; (Ref. 35393); наибольший возраст (опубликованны данные): 40 годы (Ref. 35393)
Formerly most common in deep waters of Utah Lake. Used tributaries of lake for spawning (Ref. 5723, 86798). Adults are pelagic and feed on aquatic invertebrates in the mid-water column. Juveniles inhabit emergent vegetation, apparently as refuge from predators (Ref. 35293).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [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).
Trophic level (Ref.
69278): 3.4 ±0.45 se; based on food items.
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (tm=5-10; tmax=40).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (44 of 100).
